Stealth gear-sets

I recently installed a small 2S brushless system in to a stealth-equipped RC10 and hoped that the trans could handle information technology. I think it might if the bearing, gears and even the pinnacle shaft wasn't worn. Under full power, information technology will skip a tooth occasionally. My first thought was that the bearings were too far gone but after replacing them, the meridian shaft still had also much radial movement. I plant that the installed top shaft was worn where the inner races sit. I took a take chances on a solid metal topshaft from ebay but only realized, when it arrived, that it was a 64 pitch gear. No problem I thought, simply order the other gears in the same pitch,,, merely they don't seem to be available. I can find 48 pitch idler and diff gears and I can find(and have one) 64 pitch elevation gears only I tin can't seem to discover a full ready of either pitch.

Looking for sources of new parts. I don't really care if they are 48 or 64 pitch. I understand that the 64 pitch gears are quieter but fifty-fifty the worn 48 pitch gears were repose enough.

Thorp 64P idler and unequal gears rarely surface, and the factory stealth 48P steel topshaft will easily handle a brushless mod motor.

Hello Chaos

Guess I should first ask if you have had the trans apart... And if so...

I could be wrong but a stealth trans "skipping a tooth occasionally" would leave evidence of near catastrophic failure on the confront of a gear.
And you said the worn 48 pitch gears were tranquillity enough.
I would think of either loosening the slipper or tightening the diff.
A diff that is not set properly tin can "bark".
Lots of references to diff setup here and on AE spider web site.

But I can't find the factory summit shaft either :cry:

My first problem was manner to much loose on the slipper. Tightened that and information technology either started or continued to slip the unequal. Tightened the diff and the the popping(that I assumed was a gear skip) began. Once opened, I did non seen any major gear damage, just what appears to be loose mesh and a lot of motion in the top shaft (which is all metal already). How quiet I claim it to be may needed to exist taken with a grain of salt,, I oasis't been effectually many other stealth transmissions to compare. The simply other one was a 6 gear trans and I can't call back how it sounded or where it is now.

Just a heads up I run a 4.5 brushless Novak and information technology's held upwardly fine even at the elevate strip. I run a 5.5 and even a 3.5 with a stealth but in a light car.

I've seen a few shafts on eBay shouldn't be hard to get they don't command big money yet :wink:

The stealth transmission is a golden standard.
It first came out in 1989 (30 years ago!) And is however the same in the current B6.1 and has been copied past every manufacturer.
All that has inverse is the gear ratio and the slipper. It can handle any motor a modern auto can utilise, if geared correctly.

There are plenty of height shafts (6571) on eBay, although there are less of the more modern B4 shafts (9601) equally used on the ReRe.

Cheers Bluewormx, searching ebay WITH that number 6571 showed three options that seem perfect. I had searched many different wordings but didn't know the part number.

Acme shafti is on its way...

You may all the same desire to check the unequal
With the pinion off the motor (testing the trans only), rotate ane cycle while belongings the other wheel still.
This can requite you lot a reasonable assesment of the diff'due south status. New rings and assurance should exist quite smooth. If taken apart, a fingernail dragged beyond the ring will tell the story.
Hope that shaft helps.

When I tightened it, I rotated it against itself and would not say that information technology is/was quite smooth. I would say that information technology was right in the eye of "butter-smooth" and "no mode that will piece of work". But, its also probable tighter than it needs to exist. I intend to loosen the slipper enough that I can loosen the diff a little. I am probably going to have to replace the other two gears and will plan to replace the balls and ring if and when that happens.

When considering the other two gears, does a metallic top gear, metal diff gear and plastic idler brand sense? I don't retrieve I like the idea of metal vs metal and the idler seem to be the cheapest. But I am not sure how to feel about metal balls agains the metal diff gear either. I am thinking that maybe metal top gear is all that is needed. I would happily have others experience with this, or fifty-fifty opinions.

thanks for the info to this point...

I would think, all things considered, that the plastic diff gear is ideal. Power to absorb some impact, low rotational mass, broad gear confront and quiet performance/depression friction is quite good.
The idler can be ane of two different models depending on the gear case y'all take. Splendid clarification here viewtopic.php?f=35&t=44233&p=502426&hil ... 64#p502426
The 6565 instance ( if y'all have the newer 6564 case) ,the 6580 diff gear, the 6579 unequal rings and 6570 idler ( if y'all have the 6565 case) are all available and reasonable. The 3/32 carbide balls are a little more.

The top shaft is here and in that location is very little radial play in the bearings. I am pleased with that. Just, equally I expected, there is too much habiliment and backlash in the other 2 gears to wait things to work(for long anyway).

I see RC10, RC10T and RC10GT gears, are they interchangable?

Mine has the idler gear stock-still to the shaft and bearings in the trans housing.

New gears, new bearings and this thing is silky-shine. Diff certainly leans toward the butter stop of the usability spectrum.

Would exist ready to roll if I hadn't decided to amend the front finish "a little". That fiddling quickly turned into a lot but I'g getting in that location.
