LRP set to release new Sphere Competition
LRP has taken its brushless system to the next level with a speed control designed specifically for racing. The Sphere Competition is a forward/brake controller, and with a motor limit of 3.5-turns or more, it can handle any brushless motor available today. Like the original Sphere, the Competition can also run standard brushed motors (5-turn motor limit). Other cool features include automatic adaptation to brushed and brushless motors (which means no programming required when switching motors) and "AutoCell" adaptation that allows the safe use of LiPo cells. The Competition also features ADPC (a variable, optimized motor management within six different profiles.) So like the QC2, a brushed-motor speed control, the Sphere Competition automatically varies and adjusts the profile as you drive.

AAAGH the picture doesnt work. If this thing is the same size as the regular sphere (or smaller) and doesnt have a huge cap like my GTB I'm definately getting of these as soon as I can.
Edit- Check the rccaraction main site for a picture. It looks exactally the same as the regular sphere, only with different writing on it. I'm definately getting one the day they're avaliable.

It is the same size as the original Sphere and no cap is needed.
Also, you guys are the first to see this product outside of the LRP offices.

What does the "AutoCell" feature actually do? Is it just a cutoff when voltage gets low or something? I didn't think an ESC needed anything special to run Lipo.

The AutoCell feature automatically detects if you're using LiPo or "standard" batteries. While I can't confirm this yet, I bet the Sphere Competition has a voltage cutoff so the LiPo batteries do not discharge too deep.

I have the Sphere and I love it. I only use BL motors so the only thing I could gain with this ESC is the ADPC and the use of LIPOs.
However, after looking at the picture I'm still disappointed with the 4 holes that ESC has in it. Dust and dirt can get into there if you don't seal them up.

The "auto cell" cut-off better known as Low Voltage Cutoff (LVC) is a standard built-in feature (usually programmable via PC) available on high end competition sensorless ESC's.
Since the characteristics of LiPos aren't recommended to go below a specific voltage level the addition of LVC makes it possible to "cut" the voltage at a safe level. Thus preventing damage when recharging and prolonging battery life as well.

ok to the post above with the pic. why have an aluminum heatsink battery brace when you have either tape or foam between the contact point of the brace and the battery. nm
i have had nothin but problems with lrp speed controls and thei neew one isnt going to make me buy one. i have had only one novak fry since 98. count 4 lrps in my group since last season. qc2s, plus to run a spektrum you need a large power cap, or it will shut down.

I use the masking tape to help keep the batteries in the shape I want. The battery bar does get warm and helps to cut down on battery heat. :cool:
I used Novak ESCs before the LRP and I haven't had an issue with any of them.

The only thing I'm concerned about is the weak BEC on the original Sphere. Has that been solved? If not, then LRP hasn't addressed the biggest issue of the ESC.

Glad to hear you guys like the features, the full details are going to be available during the I-Hobby show this weekend. There's more in there... :)
About the "BEC complaints", let's face it... 99% of these issues are related to racers using the Spektrum system, it works fine with all other receivers/servos. Why do you think does Spektrum release a capacitor set and an update of their receiver? Because the speedos have a problem or their receiver... They keep blaming weak BEC's, but the truth is that the Spektrum is VERY unreliable on this subject! I don't want to start a flaming war, but it's simply not true that the Sphere has a BEC issue.
Btw, the Sphere shares the exact same voltage regulator chip as Novak uses! So hard to believe this should be the problem... :)
Will there be a possibility to update existing Sphere's with these new features ? Just spend ~300euros on the system just to find out there is a updated version on the pipeline :( ...
burito
10-20-2005, 05:59 AM
@ALi: sorry, updates are not planned so far.
does this still require the heatsink kit if you run in certain conditions (touring, etc) ?
burito
10-20-2005, 09:29 AM
Yes, heatsink will be required for "high power" classes such as TC or 4wd. While it will be ok to run without heatsink in 1/12, 2wd and most likely Truck also.
WheelNut
10-21-2005, 02:45 AM
If your going to need a heatsink to run it in TC (assuming that is with the lowest turn motor currently avaliable, 5.5) how in the world could it run a 3.5 motor without thermalling? If it can actually run a 3.5t motor that thing would be smoking hot, no?
why didn't LRP just include the heatsink right way for this? Seems this would be a great thing to do, have it all in one and probably will cut down on people blowing there ESCs too. I believe novak does this already?
burito
10-21-2005, 11:15 AM
@Cain: not sure if I misunderstood... but the heatsink is included of course, it's just not mounted from the factory because some classes don't require the heatsink. Also it does of course look neater and is easier to mount without the heatsink for 1/12 and 2wd, as I explained above.
@WheelNut: lowest you can get at the moment is 5.5t, but you're just ready for the future with the Sphere Competition... :)
Rtsbasic
10-21-2005, 11:22 AM
Hmm, tipping the balance towards LRP again :) This with the Novak GTB 5.5 motor on 7 cells would be quite fast :) Would probably push the controller quite close to its limits though.
Maybe LRP plan to come out with a 4.5 motor in the future to pair with this controller..would be nice.
I think my question is based on what people with the current sphere are stating that you need a heatsink/capacitor combo that is bought seperately. Am I to understand that this is now included with this newer sphere?
What I am waiting for with brushless is where they have alittle dial that I can set for the following performances:
10 turn
11 turn
13 turn
19 turn
stock
something that just goes like that with similar power performance to those settings so I can dial in.

Instead you might be able to buy a higher turn BL motor. Check out these Neo 1 motors on Tower Hobbies website:
http://www2.towerhobbies.com/cgi-bin/WTI0095P?FVSEARCH=neo&FVPROFIL=
There might be a 11 and 13t BL Neo 1.
burito
10-21-2005, 12:45 PM
@cain: the "original" Sphere does also come with a heatsink, no need to buy that separately of course! But the fan and powercap are sold separete, if this is what you're refering to.
Dialing in different winds into a brushless speedo is almost impossible, at least as far as I can see at the moment. Wouldn't be very efficient doing that at least... But we do offer different winds, which represent your winds pretty well.
Any plans to include the option to program via PC?
I understand that this feature comes standard on ESCs built on the more advanced sensorless technology.

When is the launch of this new speedo? I was looking at getting the other sphere. Now I will wait for this new unit. :D
WheelNut
10-22-2005, 02:43 AM
Burito- What I meant was that if this model will get hot enough to require the heat sink with a 5.5t motor, then would it not require at least a fan to run something like a 3.5t motor? Although I suppose its still a big improvement, considering the Novak GTB needs a fan+huge heatsink to run only a 5.5t motor. If this Sphere model can handle a 5.5t motor without needing a fan that is certainly an improvement.
burito
10-23-2005, 03:32 PM
@Key: sorry, nothing like that is planned for the near future. Btw, sensorless really isn't more advanced then the Sphere Competition is... :)
@dodgeguy: don't want to give a date at this stage which we may not be able to achieve! Will have more information about delivery within the next few weeks.
@WheelNut: yes, it might be required to run a fan for low-turn applications in "power hungry" cars. When correct gearing is done, a 4.5t could be used without the fan (but of course the heatsink!). But don't quote me on this since ambient temp, type of car, gearing, driving style, track layout etc have a huge effect on the speedo temperature.
Burito thanks for the response. Yes, sensored technology have made some improvements lately with the introduction of the Sphere and GTB line of controllers but not quite up to the feature rich Sensorless standard.
The reason I was curious with programming ESC parameters via PC is that it can open doors to additional tuning areas that were once unreachable through sensored and/or brushed ESC's.
On the other hand, Sensorless ESCs such as the U-Force 75 and Mtroniks (brushless versions) are generally built with the intention of handling higher Amp draws continuously without sacrificing handling and overall smoothness equal if not better than running on a brushed motor. This feature also comes in handy particularly when running higher voltage LiPo setups such as 11.1v or 14.8v with lower kV rated (higher turn) sensorless brushless motors.
There are numerous advantages to programming an ESC through a computer besides access to additional parameters. One of them is being able to perform updates/upgrades to the controller’s firmware through manufacturer’s website. This eliminates the process of having to physically send the ESC back and forth and is an added step forward for brushless (and LiPo) technology.

Actually, let's face it: the Spektrum doesn't have any of these problems with the GTB system from Novak.
Don't be so quick to pass the buck.
[edit]
And PS: My buddy, who owns a synth XS3, had the exact same problems with the Sphere/NEO that I had with my DX3. Neither of us are having these problems with our GTB w/6.5 motors.

@tbone77: can you excribe the exact problem you and your friend had? So far the only feedback I get is "we got a problem", which doesn't help since we found it to work flawlessly when we tested.

Not to sound argumentative, but why? The Sphere has a sportsman mode for stock... why couldn't additional modes be added?
< That's rhetorical question, I already know (http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXLRH2&P=7) the (http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXJJG2&P=7) answer (http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXLRH3&P=7) ;) >
By the by, speaking of sportsman, will the Competition include that mode as well? It's pretty handy on the current one.

Sorry but I have to disagree with you there. The Novak GTB has more usefull setup function that ALL sensorsless controllers on the market lack:
min drive
min brake
drag brake
dead zone
Now they might not look like much, but I can tell you that they make the world of difference when trying to lose 1/10 of a second off your lap times.
Also a car with sensored system will get a better start off the line and may even pass a senorless car before the first corner.

These and more functions are available on the Brushed/Brushless , Sensor/Sensorless ESC from Graupner , the Genius 80 just cost 135 Euro in Europe.
UF75 (2/3 years old ESC) does have these features ...

PS: Why the LRP Sphere cost much more then the Novak GTB ???
The GTB isn't worst then the Sphere ...

Sorry yes the UF75 does have these features, but you need a laptop with a serial port and the special interface to adjust them.
The Graupner esc is so far unproven, I didn't know it had those features. I hope you don't need a laptop for that too.

Further to the correction made above the question should be - can the GTB or any other sensored based esc provide the option to program via PC in the areas of :
- Adjustable Low Voltage Cutoff
- RPM Motor Limit
- Brake threshold
- Stick deadband frwd / rvrs
- Brushless Motor Type (2,3,4,6-poles)
- neutral positioning
- throttle positioning
etc, etc, etc,
The U-soft's cabling options are either thru Serial and/or USB and I'm personally using the latter for the added convenience. There are over 20 parameters available for adjusting to the nth degree in order to keep up with the demands of available LiPo formats (2s, 3s, 4s) and Sensorless x-pole motors available to date. Hence this accounts for faster acceleration / speed :)
novak and or lrp should be taking notes ;)

WheelNut
11-05-2005, 02:58 AM
Yeah and the U-force only costs $275! Plus the USB cable.....thats crazy! I do have to say it is an incrediable ESC, but that price is wild. And its pretty big as well. I think I'll stick with LRP/Novak.
Yes, they are expensive. The software, cd and cable cost an additional $23. Aside from cost and imcomparable features can you name an esc to date manufactured up to the specs this esc brings to the table?
I'm not quite sure what the issue is as far as dimensions - the gtb without its large external kidney is 12mm shorter in length similar in width and much taller in height due to its fan. Everything in the UF is integrated runs cool without any protruding devices and no sensors/xtra wires.
If lrp and novak had come up with the U-Force based specs would there be any excuses then?
I am not putting down other ESCs in any way but credit should be given when due.
Schultz can demand whatever price they may feel suitable as there are no manufacturers that are able to patent anything close to this 3 year old brushed/brushless/sensorless technology designed around Lipo
and NiMh in mind.

The only feature I need out of those is the low voltage cut off, and that's not hard to do without. A lot of the other things I can use the transmitter to adjust. Certainly don't need to set motor type ;).
The other reason to go with the GTB is the fact it is legal ;). Next year I plan to race in some more nationals as I did this year and I will need either the sphere or GTB to be able to use a legal motor.

To outrun the competition every string of detail is looked at in terms of car/motor adjustability and that's what separates the winner from the rest of the pack.

There are no legal senorless motors. The U force is only splashproof.

You could drop almost any kind of motor you give this baby. This includes any "legal" brushless sensored and brushed types. Hence the reason for the motor type parameter changes made available for programming.
The reverse cannot be applied meaning a sensored based ESC like the Sphere Comp cannot run the more robust sensorless/wire-less motors.
The UF75 manual terms it as "SealTec Water Resistent". Rain is not an issue.

I wasn't aware it could run a sensored motor using the sensors. If you mean you can just run the novak motor in sensorless mode then you are missing out on the none cogging(I hate any cogging) feature of the novak system.
I wouldn't want to run a sensorless motor. THEY ARE NOT MORE ROBUST. They have crap wires sticking out of the ends, these are the wires that actualy go around the coils and once they snap off you've not got a usable motor anymore. The cheaper ones are very low qualty in comparison to a novak.
Has anyone tested the waterproofing on the shulze?

Let's try to keep this on topic guys :)
Yes this is going on a tangent and will make this very short in response to post#50:
"Crapy wires/quality" would be the last thing in mind with sensorless motors since it caters to planes, as well as helis. Again as mentioned prior to this the majority of motors out there can work efficiently with the more advanced UF75.
Anyhow in reference to this topic - I've witnessed the current Sphere in action, its fast and efficient enough to run cool and I'm sure that their brushless Sphere Comp series will provide better results within sensored technology limitations.
-Key
sensored technology limitations.
-Key
And what would they be? lol
One of many limitations would be inability for a sensored ESC to charge a pack under brake. It may not mean much when cruising around but certainly not during legalised competition.
The list goes on but to allow more focus on the Sphere Comp subject, more info is made available within the brushless section of this forum for better overall understanding of brushless/lipo/sensorless/sensored systems.

from what I have seen the GTB costs more than the Sphere. I was looking at doing the sphere but the reports I have gotten of problems with it just made me stay away.
The GTB with a Novak 5.5 motor cost less then 250$ in US , and less then 250 Euro in Germany.
The LRP sphere ESC only cost around 230 Euro in Germany.
So to me it sound that the LRP is by far more expensive then Novak !
Even from Europe is more effective to get the Novak, from a US eBay seller.
e_lm_70
Why would a sensorless esc not be able to do that?? The only difference between the two design concepts is that the sensorless uses back EMF instead of hal affect sensors. What are all these other things that you have on your list? Might as well write them here because they may be false as well...

It is on topic.
The Sphere is a sensored esc. There is no reason that if sensorless can have regerative braking the new sphere couldn't.

Post 54 was meant for the GTBs inability to charge back under braking which is incorrect but that definitely doesn’t require this sort of premature negative attitude.

Have I responded to you in a rude manner upon providing your disagreement based entirely on useless/false information that someone else had respectfully corrected? Or jumped into stating that your subsequent disagreements were all false?
Consider your actions first before jumping into others.
The point is that there aren’t any sensored systems out there to-date that can perform what was mentioned earlier including critical Lipo and motor functions readily accessible thru a number of sensorless units especially when considering Schultz standards.
Maybe this is an area LRP may consider in the near future.
-Key
You said that sensored could not do those things, which you have agreed was a false statement. The gtb is not designed with liop's in mind, but that is not because it's sensored. I have already said that the fact the schulze does those things was news to me and have been modest enough to admit I was wrong. You should swallow your pride and admit you are wrong in saying senored cannot do anything sensorless can do. Just because the GTB might not be able to do it doesn't mean it cannot be done.
So to sum up..
Sensored is not any more technicaly limited than sensorless.

Corrections over your points were adjusted a number of times not just once and were intended to make readers aware of facts . Certainly not to insult as in your earlier scenario that clearly shows no subsequent sense of guilt or modesty.
Can you say the Sphere or GTB (sensored) currently provide the same enhancements as the U-Force75 (sensorless)?
Then what doest "swallowing ones pride/admitting" have anything to do
with the current facts?
Rather than underestimating the capabilities of sensorless units by throwing multiple best guesses reviewing its functions preferably thru their manual, tech support responses, etc.. can definitely provide a better understanding of its capabilities under the sensorless umbrella. Considering this approach may have avoided or the very least reduced many of the reoccurring misconceptions stated earlier around sensorless units.
In terms of currently available brushless systems sensored is technically limited than sensorless but certainly the gap is much closer with the introduction of the Sphere and gtb

I have the Sphere + Vector and it goes really good. The "auto cell" cut-off better known as Low Voltage Cutoff (LVC) is an improvement. But i'm still disappointed with the four holes that ESC has in it. Dust and dirt get into there and cause malfunction at the switches. Novak GTB doesn't have this "little" problem and it's waterproof. So, i still prefer Novak GTB.
PS: Sorry about my english :o

Any idea when this new ESC will be out?

I just got my sphere and ready motor this last weekend and ran it in 2wd truck. I noticed that the motor temps were like around 150 and the esc was blistering hot after a run. I went and put the heatsink on the esc and it seemed to help. My batteries were also like 150 after a run. I had it geared at 20t pinion, was it over geared and made it run hot? Anybody else with some temps on theirs?

what truck are you running it in? 20t does sound high, when I ran one in my mf2 I had a 17t.

I would go down to a 17 or 18t and check to see if the temps are any better. I just checked novaks site and they say a 18-19 for there 5800 system. The reedy is a higher rpm motor so it should be geared lower.

A 20t pinion is definately way to large. Go pick up a number of pinions for your LHS, get 16,17, 18, and 19t gears. That should cover just about any condition you come across.

Is there any idea's on a release date? I have just begun my search for a sphere ESC and I realize there is a latest and greatest. I can continue to run my novak 5800 for a few weeks but I don't think my paypal balance will hold up it I've gotta wait over 4-5 weeks....
Doubting I'll be able to extract a guestimate on a date but worth a shot.. lol

Targeted release is January!

Sounds good. I was hoping to see it at least listed on Tower with an estimated arrival date as they already have products listed that should be out in Feb.
fingers crossed.

January for the ship date?, like first of January? I am ordering some stuff around the 15th and if its out and I am sure that it will not have issue with my DX3 I am going to order it.

Doesn't the fact that it has no reverse bother anybody?
WhoMe

Its a competition level speed control. Reverse is illegal in racing.
WheelNut

Does no reverse bother me? Nope. Having no reverse just teaches you to drive better. Not to mention it allows them to make the ESC smaller and more powerful.

No, it's a pure racing speed control.

To give you an update about the release date of the Sphere Competition... It's still January, but looks like 2 more weeks or so right now.

Okay its february, has it been shipped yet????
burito
02-09-2006, 03:16 AM
Yes, the first production batch has been shipped to distributers a little over a week ago. They should be "popping up" in hobbyshops allover the world while I write this. :)

How about the QC3 Burito, have those shipped yet?
burito
02-10-2006, 11:33 AM
Nope, unfortunately no QC3's yet and I'm unable to give you a schedule on those. Sorry.
But at least we got the Sphere Competition now. :)

Burito,
I read that the new Competition Sphere ESC is compatible with LiPo cells. Does this mean that under no circumstances should I ever use the LRP Sphere ESC with LiPo cells, which then also means that I can only use NiCad or NIMH with the original Sphere?
2s lipos are so similair to 6 sub-c that it should never be a problem unless you overheat the esc or motor.
burito
02-10-2006, 04:39 PM
@chilly: as Jev said, you can of course use the original Sphere with LiPo's as well. You just don't have the protection of the battery against deep discharging, just make sure you're not crawling around when the battery is empty and you'll be fine with LiPo's and the normal Sphere as well.
chilly4kc
02-10-2006, 05:50 PM
Ok one last question. With the Sphere, if you switch from a brushed to a BL motor I notice that you have to go through the setup each time (brake, thorttle, neutral, etc.). With this new ESC, it automatically detects what you are using.
So does that mean that you don't have to use the setup mode each time you switch motors 9brushed vs BL)?
If so, will it retain the settings last used, or do you have to go through the profile and tell it what settings you want?
ErikRC10
02-10-2006, 07:19 PM
It just uses the set up last used is what I'm guessing.
burito
02-11-2006, 05:31 AM
@chilly: no new setup required whatsoever when changing between brushless + brushed. actually you'd not have to do a new radio-setup either on the "normal" Sphere, rather weird that you have to do that!
The mode settings (LiPo/NiMH, power profiles, initial- and autobrake) are obviously the same when you change between the 2 motor types. So in case you prefer different settings for brushless or brushed, you'll have to adjust the values to your likes.

Burito,
Can we get an ETA of when LRP will be making a support presense in their own forums?
schenck77
03-04-2006, 12:03 AM
does any one know a place that has these in stock? burito said they were shipped almost a month ago but tower doesn't have them listed and stormer says order pending.
redsixer
03-06-2006, 02:15 PM
And where is the QC3?
ErikRC10
03-06-2006, 05:35 PM
Yea really where are they?? Tower's said late feb but now their saying mid march. My b-day comes to soon I guess I'm gonna have to get the reqular sphere instead.
schenck77
03-06-2006, 07:45 PM
I wouldn't get the regular sphere. way to many people had problems with them. The only reason I am even considering the comp version is because it has a lvc for lipo's. This time I will make sure other people test them out and get third party feedback before buying one.
schenck77
03-15-2006, 05:04 PM
incase anyone is interested, it looks like they finally made it to the hobby shops. tower has them list as limited quantities. now if tower didn't have a rediculous price.
ErikRC10
03-15-2006, 05:10 PM
yea peoplehobby.net have them for $189 that's $100 less then what towers has them for. ppl hobby had them in stock a couple of days ago but they're "on order" now.
On the Tower note--did you guys also notice (at the time of this writing) that you can get the Sphere Competition + a Neo One 4 Star brushless combo for 14$ less than just the Sphere Competition ESC by itself? I'm sure it's just a typo or the Sphere Competition price is still the retail price.
ErikRC10
03-15-2006, 05:14 PM
lol RobK I was just about to post that!! lol literally I was. The price of the Competition on towers should drop soon. if it doesn't then they are pretty screwy.
I was the 100th person to post on this thread!!!

Either Tower or LRP has misprinted their info. If you look at the Sphere/Neo combos, all the motors have the same kv rating. I don't see how 13t and 7t BL motor can have the same kv rating. Since the Novak ESCs can only handle 6 cells with their BL motors, I wonder if the sphere competition ESC can handle the 4.5t novak motor with 7 cells.
ErikRC10
03-17-2006, 08:55 PM
Yea Tower prolly misprinited it or somethin..... I would think there was any reason that the Comp couldn't handle the 4.5r and 7 cells... I mean it's not at it's motor limit yet even though it is at it's cell limiet. If you try it though and have a big kaboom dont' blame me.
schenck77
03-22-2006, 11:12 PM
tower now has them in stock and fixed the price. its now 209 for the esc and 269 for the combo. also just wondering if anyone has tried one yet? I want to see user reports before I consider picking one up.

My local shop in Ohio has them for $199. Very good price.
schenck77
03-23-2006, 03:34 PM
bobf24,
I look forward to hearing any kind of review you can offer. Do you have any other brushless system to compare it to? I run lipo's too and that is why I am considering the lrp comp. I already have the gtb but want a unit with the lvc built in.
ErikRC10
03-23-2006, 06:26 PM
I will hopefully get one in the next couple of days. I asked for one for my b-day and my aunt and uncle really sounded like they would get me one. So if they got it for me it should be here within the next couple of days. I got my present from my dad today, I wanted/needed a FT B4 but he got me a portable DVD player. It's pretty cool for something non r/c related.
bobf24
03-24-2006, 02:36 PM
well i wont be able to give a real good review of it on a track, since i live in canada and its still too cold and snowing, so no tracks are open, but i'm gonna bomb around the back yard, and i'm going to an indoor track this weekend to run a nitro race, so i mgiht bring it along just to try it, and no, this is my first BL system, so i can't compare it to anything else, i got it because of all the reviews i've read, the LRP is supposed to be the smoothest, and the tracks around here are really loose, so smooth is good, and i like the LVC too, and it seems like the LRP is better sutied for offroad, the novak seems like they are more meant for TC, which i dont run,
bobf24
03-24-2006, 08:35 PM
well i got the system installed, first impressions are it rocks, no issues setting it up, i'm running it in a BK2 with a NEO 1 star i think (what ever is the 13T one), with the orion lipo, and its got a TON of punch, my parking lot is wet, and i had dirt hog tires on, and i was just about pulling wheelies, even with little to no traction, i can't imagine what it would do with one of the hotter motors in it, now i really want summer to come so i can start racing it,
i didn't run it very long so i can't say if the auto lipo detect thing worked for sure, cause i never got near the cut off voltage, i only ran it for a couple minites, just to set up my diff and see how it worked, and one other thing, you can deffinatly feel the lighter battery, the car was very light on its wheels, and felt alot more nimble, but again, its hard to tell in the parking lot and not on the track, but as of now, i'm very happy with all the parts,
schenck77
04-03-2006, 05:00 PM
anyone else try one out yet? I am interested in seeing how it compares to the gtb. also does anyone know what the voltage cutoff is set at for lipo's?
ErikRC10
04-03-2006, 06:38 PM
I finally got my Neo 2* in the mail today but the esc is still on back order so I don't know yet but will let you know when I get it.
jnegrx
04-05-2006, 12:18 AM
bobf24:
The 1 star is 13turn equivalent
the 2 star is 11 turn equivalent
the 3 star is 9 turn equivalent (original NEO)
the 4 star is going to be 7 turn equivalent.
I have the original Sphere with the NEO in my FTTC4 and it is a bullet. I just can't wait to try the 4 star with the Sphere competition.
ErikRC10
04-05-2006, 07:18 PM
hey jnegrx Reedy is actually coming out with a 5* if you want to wait. Well I'm not absolutely sure on this but that's what I read in a RCCA article. Also the 4* has been availble for quite a while now.
jnegrx
05-01-2006, 02:04 AM
Yes I know that the 4 star is out but the sphere can't handle it.
4. From Our Mailbag (AE Insiders news letter April 7, 2006)
Q: Will the original LRP Sphere be able to handle the Reedy 4 Star brushless
motor?
A: No, but the LRP Sphere Competition will handle it.
