BK Pitch Gears for XXX. Are they worth it?

[LosiMan3456]

anybody???????????

[Oyster]

I wouldn't use BK pitch if they were half off. They are a different pitch, you'll have to figure out how to convert. You'll be buying spur gears and pinions... for what? I don't understand why people use em.

Save your money. Buy something you can actually use! :)

I am going to practice tommorow and was wondering if I should try the BK gears for my XXX. Are they any good? What are the pros and cons? Also since they are a different "pitch" will a BK 82/23 gearing be same as a team losi/RRP 82/23 gearing? :confused: If not how do I get the same ratio. Right now I am running a 82 tooth team losi spur with a 23 tooth RRP pinion. Thanks

Don't get sucked into the marketing hype. BK pitch gears were designed for the sole purpose of sucking the consumer dry.
Mark my words, in a few years they will be a thing of the distant past. You will have to go re-purchase pinions as nobody will be supporting that proprietary gear pitch, including Trinity. (by then they will be on to "MF Pitch" and sucking even more people dry)

[Railman]

If you want a full blown discussion on the BK gears go to the vehicles forum/XXX or XXXT (can't remember now) thread, & do a a search. They were discused quit a bit. Too much info to retype. There are benefits, but also many drawbacks. Joe

The only reason I would get BK pitch gears, is mainly if I had an on-road car, so, that I did not have to stock my pit-box with 48p and 64p gears.

but, I have yet to see a problem with my 48p gears.

BTW, I have noticed that Team Losi pinions run a little quieter, you may want to try them out, plus, they last a long time.

Hey thanks! I didnt get any. I used to run losi pinions but I like RRP better now. dont know why

[DerekB]

There are no cons or sucking going on with BK pitch. I wonder if this discussion went on when 48-pitch and 64-pitch came out? If you already have a full set of spurs and pinions for your cars, BK pitch may not be for you.

BUT, if you have not purchased a set of pinions or have multiple cars BK-pitch gears make a whole-lot-o-sense. They are in between 48 and 64 so you'll have to calculate if you want to match somebodies gear ratio. You can use these gears on and off-road (you'll notice that BK and most Trinity drivers use them on EVERY car they run) You won't have to buy 64 for on road and 48 for off (the normal). So I owuld get BK pitch gears (I use them).

Don't get sucked into the Everybody wants your money theory. EVERY manufacturer want to suck you dry, that's why they are in business.

LosiMan,

I don't know the pros and cons of the BK pitch, but I just wanted to point out that if you decide to switch to BK pitch, you don't have to recalculate any ratios. Remember, the key word here is "ratio", so 82/23 ratio will be identical no matter what pitch you are using. Of course, the spur and pinion will have to be the same pitch in order to mesh properly.


Regards,

George K.

Trying to stay polite and objective here ...

I agree that companies exist to turn a profit and make bank. No Earth shattering news there ...
I am strongly opposed to any "cross platform" type product that has but a single manufacturer. Trinity will drop BK pitch. They will. Trust me. And you will be left with some half-breed, completely unsupported, proprietary crap.
Also, don't forget that you need spur gears to go along with those pinions ... do they make BK pitch spur gears for your Kyosho cars ? For your Tamiya cars ? In fact, BK pitch spur gears are only made for current, very popular kits. Why ? Because "BK pitch" is a single vendor supported product, unlike 32/48/64 pitch gears which EVERYONE supports.
Even if you have no gears and want to buy some, I recommend using a standard agreed upon by ALL the manufacturers.
I do agree with the single pitch phillosophy, but until it becomes at least an informal standard, I recommend you stay away from BK pitch.
I would be more supportive if they called the product something other than a person's initials. A person who could be racing for AE tommorow. Yes, unlikely, but possible nonrtheless. It just screams "short life cycle" and "quick buck", at least to me.

BTW, 48 pitch and 64 pitch came out so long ago that I doubt there were even cave men :p
So, I coubt there was any complaining going on.

[DerekB]

The BK pitch gears will fit ANY car when you use a adapter that you would have to use no matter what aftermarket pinion/spur you use. None of the US spurgears fit Japanese cars.

[Railman]

The reason finer pitch gears may never be a new standard is because by design the will always strip easier. It's not intentional, its just that the mesh has a lot less tolerance to it. A lot of folks can't keep from stripping 48 pitch, or in the case of the gassers, 32 pitch. There is however a performance advantage to them, & for that reason racers will probably switch... eventually. They will never replace the 48 pitch gears because of the precision needed to run them is just too hard for newbies, & some bashers. Just my $.02

[jeepinator]

Derek, I was not referring to aftermarket spur gears, but the spur gears that come with the kits.
I am quite certain there are hundreds of cars that cannot use the BK pitch pinions because there are no BK pitch spur gears for them.
I have owned so many kits that I cannot even remember them all. My trusty collection of 48 pitch gears has fit all of them !

[DerekB]

There are 2 basic (US) spur designs. Losi and pan car style. Losi requires a special spur gear because of the slipper design. The other style is the one used in pan cars with the balls. This will fit most cars. You are missing the point that if you are buying pinion/spur gears for the first time the BK-pitch is a viable alternative. I'm not asking you to switch all your gears.

[jeepinator]

OK, I see your point.
I think we pretty much understand each other ...

One last note: (sorry I am really not just trying to get the last word in)

Tower Hobbies lists 3 styles of BK pitch spur gears:
1) Losi (only the newest dual plate slipper design)
2) "Standard Diffs" (but ONLY in 96, 98, and 100 teeth).
2) TC3 (size not listed)

This means that if you have a new Losi car or truck (no original XX, JRX, etc), or a TC3, or have little need for a wide variety of choices for AE kits, you can use the BK pitch. If you have ANY other kit you cannot use BK pitch (modifications notwithstanding).
So, if a person (first time buyer) decided to go with BK pitch, and then later bought something other than the above list he or she would have to buy two sets of gears anyway. Seeing how 64 pitch is not required on most of the kits that can use it, there is rarely a need to buy 2 sets anyway (unless you buy BK pitch first :p ).

So, I see your point ... do you see mine now ?

BTW, Tower may not list all that is available ... is there a better source for what Trinity offers ? Their website is definately the LAST place to check for product info. How sad.

[DerekB]

I never disagreed with you, I just didn't like the negative tone in your post. I see you side, but there's always two sides to a story.

I'm not sure where a better Trinity parts list available is, when you find one let me know too! :cool:

[jeepinator]

Derek, do you have any relatives that own a company is Portland, Oregon ?

[cabbynate]

BK Pitch spur gears are machined, not molded.They are much stronger than standard spur gears.I don't think many will get stripped out. ;) I run them in my XXXT and they work great.

[Cosmo]

The main problem I see with BK pitch is that nobody else runs them. I have yet to meet someone that uses them. If I am at a track and I need a gear, there is a much better chance that I can either borrow or buy a 48 or 64 pitch gear than find a BK pitch gear.

[cabbynate]

Cosmo-I know what you mean. I am the only one at my track that runs them. I also have to order them when I need them. It's a hassle to run them I know but they are so smooth! I don't run them in my XXX or my XX-4 because I don't race them that much but if I did I would bite the bullet and get more. I like them that much. Why do ya think all the Trinity/Losi drivers use them? ;)

[jeepinator]

BK should stand for Butt Kissing.

[jeepinator]

Well, for all you BK pitch freaks, here is THE BK find:

[Hairball]

Ok, if I remember right, BK Pitch gears = 52 pitch gears. (or really close to that).

the purpose was to get the strenght of 48 pitch gears and the efficency of 64 pitch gears and combine the two.

I kinda wish it would catch on. Having one set of gears for ALL my cars would be sweet.
