tt-01 ESC

[No Moa]

Hi all, i bought 2 TT-01 cars, one is a NSX and it has a Tamiya GT Tuned motor. I have no idea what to get for a ESC? and a battery. I have a Futaba radio. Any help would be great. These are just for bashing, not racing.

The second one is a Mercedes with a stock motor, no servos or anything. So i need cheap radio option, and other info.
Thanks

Anyone?

Lrp makes any number of small, lightweight esc's that will fit your needs. Check Tower or Stormer. If you're just running the stock silver cans you won't need a high dollar speedo capable of handling low turn motors. Not sure on this but I think the GT is a 25 turn. As far as radio's go you can't beat Futaba's 2ph-it's your basic AM no frills type unit but about as reliable as they come. If you think you might want to expand your collection check out Futaba's 3PM. It's more than twice as much as the 2PH but is FM and has a 10 model memory-so the only thing you'd have to buy in the future is a receiver and crystal.

Thank you, is there a post, or an article somewhere that explains motors, and ESCs. I don't know alot, i'm used to 1/5th scale cars. I need to do some reading i guess to learn about motors, brushless, brushed, different turns and so on.

Well, I'd imagine if you searched this forum you'd probably be able to come up with all the information you could ever possibly use, but here's a few things off the top of my head...
With electric motors, "turns" refers to the number of times a strand or wire is wrapped around the armature-generally the lower the turn, the faster the motor. When you hear people talking about "stock", they're referring to a 27 turn motor. "Spec" is 19 turn, and any turns lower than that are considered "modified." Most of today's brushed esc's are rated to handle a certain type of motor-For example Lrp's Quantum Comp.2 is rated to handle motors down to 5 turns-so it can be used with any motor 27 turns down to 5. Some speedos can be pushed a little, (as in running a 4 turn motor on an esc rated for 5) but you risk burning out both the motor and the speedo.

Brushless motors are a whole other animal-While some are rated by "turns", some are also rated by amps, and while the airplane guys have been using them for year's they're relatively new to the onroad hobbyist. The performance of a brushless vs a brushed of the same turns is significantly higher, one difference being you no longer have the drag of two brushes held down by springs grinding away on the comm-longevity is much better, maintenance is minimal, and efficiency is superior. I'm no genius when it comes to these things so hopefully someone else will pipe in on the subject, or you could check out the FAQ's at sites that carry brushless motors.

One thing-some might say that, the TT-01 being an entry level car, it wouldn't be worth it to install a brushless setup, but it really depends on your level of commitment-For example, Novaks latest brushless setup, which includes the motor and esc, runs around $240 at most places. For the same level of performance from a brushed motor you're looking at roughly $50+ for a motor, and usually well over $100 for a decent esc, but you can't think of it like "Hey, for $150 I'm good to go, just saved $90 over going brushless", because brushed motor's require a LOT of maintenance that over time, (less than you would think) will add up. Not to discourage the use of brushed motors, just something to think about if you plan on dropping a wad of cash.

A major consideration that you haven't mentioned is batteries-Try not to skimp on this because these are the deal-breakers when it comes to getting the most out of an electric. Doesn't matter if you buy the latest and greatest platinum edition super mongo esc/motor combo, it's gonna perform like a turd on a cheap battery pack. Current fav is IB's 3800 but the old standby GP3300 still works well if you go NIMH, and they're dirt cheap anymore-someone here posted you can get GP's at Radio Shack!

I could go on but the length of this has already made me go blind.

Thank you for all that, i like the idea of no maintance. I won't use these everyday, but often enough, and i don't mind spending a bit to get 2 cars that will run a good long time, and as for batts, i wanted to get through the motor and ESC first.

I mean, what am i going to do with Brushed, i'm not into buying a lathe to cut them, and i wouldn't know where to begin, back in the old days on my brat, we ran it till the motor would move no more, toss it and buy another. At this point less work, much better.

I have done much searching on Google, and several sites to find the best for me and my 2 TT-01s, i am also looking into a TC4 to build up, here again, just learning. But i like the design of the TC4, and i'm an associated fan.
I'll check out those batts. i'm running GP3300s in my 1/5th scale right now, and they work great, but i'm sure it doesn't use the draw that these cars will.

Anymore help would be great, if you have a set up that you would recommend, that would be even better, just going to run these on a concrete floor, want to be quick out of the hole, don't need 50, but 40 would be fun! :') I'm going to look into a ESC for the Brushed i have, run those then look into a Brushless system, maybe in the TC4.
Thanks

Hee hee. I hear you. That's exactly what I've always done. I actually bought a cheap comm. lathe once but it was so out of true it quickly became a boat anchor.

As far as setup goes, you'll probably need at least a 9-turn to try to get anywhere near 40, although you may be limited by gearing-The TT-01's got only a couple of fixed motor mount positions, right? Trinity's got a line of relatively inexpensive motors called Speed Gems, roughly $35 at Tower. You normally gear down (smaller pinion or larger spur) with modifieds, but you can try it with the stock gearing and see how hot everything gets.

If the concrete you'll be running on is smooth you'll want the suspension set as soft as you can get it and you'll need decent tires. Try the stockers to see how they work first-On rough concrete I've always found Tamiya tires to work just fine, and HPI makes decent 24/26mm rubber in a variety of tread patterns. The smooth stuff (garage floor smooth) will require either a very sticky rubber compound-and even then it still won't hook up as much as you might like-or a soft foam. Pinks (30 shore) are a good compromise between grip and longevity. You might try pinks on the rear and purples up front.

Let me know how it goes!

This is a smooth painted floor, so its going to be slick. I'm going to get a good ESC and use the Brushed i have for now. When i toast them, if i like the way the car goes, i'll invest in a brushless setup. But i got the brushed, and they are brand new, might as well use them up. I found this on Tower for a cheap ESC,http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXGNG5&P=ML This it will work with my stock motors? And a couple of these for batt packs. http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXKAT7&P=7
Thank you for the help
