please help an old rc addict out.

[shane]

I feel like the "Ripp VanWinkle" of the rc world and I just woke up after a 20 year nap...and I have questions. Any info is appreciated.

Question #1- How many variants ( including upgrades ) of the stealth trany did AE make for the alum. tub, and what are the FDRs?

Question #2- How many different aftermarket transmissions were made to fit the alum. tub rc10? Who made them? FDRs?

Question #3- Does anyone make ceramic diff rings ( I know B-FAST has rings out there, but are they ceramic)?

Question #4- I see the gear diff in the current AE transmission is packed with black grease(#6588) and AE offers various silicon diff fluids ( numbered in CST, what is CST?), so my question is what silicon diff fluid is equivlnt to black grease (so I have a basis to work from)?

Thank you for your help

1) 2.25

2) a&l, mip, rpm, j-car, trackmaster, team pit stop, brp............. that's all i can think of off the top of my head. i'll let you spend the time looking through the scan archives to find all of their final drives, though.

3) i'm sure someone offers ceramic diff rings......... they used to be available. but that'll depend on what you want to use them on.

4) i can't help you there. i don't care much about the new stuff. but i don't see how there would be an equivelent diff "fluid" for "grease".

I can't think of ANY changes to the original Stealth tranny throughout the run. There have been changes to later cars that can be retrofitted to the Stealth (T3/B3 slipper plates and pads, top shaft and dual-disk slipper from the B4/T4), but I don't think they did anything to Stealth at all.

Greases - black (ie graphite) grease goes to the thrust bearing. Silicon "Stealth" lube goes on the balls/rings, note that contrary to the name it's more of an anti-slip fluid than a lubricant.

Then in your question, you are mixing ball diffs and gear diffs. Gear diffs are filled with silicon "oil" (which, again, don't lubricate much) available in different viscosities - the stiffer (more viscous) the fluid in the diff, the "harder" the diff will be. 8th scalers use gear diffs, most 10th scalers use ball diffs

Hope this helps,
Paul

Mmm, sort of. Until a few years ago gear diffs used grease, until 1/8th scale buggies started making sealed fluid-filled gear diffs more popular. Most racing cars had ball diffs and other cars had bevel gear diffs, which were easier to build and more durable (I have some in Tamiya cars that I've never taken apart), but didn't perform as well. The silicone oil diffs are stiffer or tighter, so they are better at handling lots of power, which is why 1/8th scale buggies had them. Some smaller electric vehicles have them now, but some still use the older grease-filled style.

The Associated gear in the SC10 and others uses grease. If you used silicone oil in the fluid would leak out over time, so stick with grease.

Sorry guys,
I fell into ( scr8p pushed me ; Beware forum newbies, I think he likes doing that to us ) into the scans archive and tech forums and I almost got lost. Thanks for your help tho.
I was researching compatable transmissions for the rc10 for my modern project. I was looking at the gear diff in the B4.1/T4.1 manual for possible use, and in the manual, it has black grease applied to all parts of the gear diff, but does not show to apply any lube to the gears, and in the parts manual the gear diff is listed with optional diff fluids (part #s 5450 thru 5459). I just thought it was odd.
I have a new built 2.25 stealth, a new built MIP sp-1 H.D., and the modern AE 2.6 transmissions to work with. The MIP transmission does not have a clutch, so Im hoping that the modern AE clutch will fit. I might put the gear diff and clutch (from the 2.6) in the 2.25 stealth. Not sure where to go on this. Anyone have any ideas? I'm starting with (all new) a basic alum. tub, wide track front end rc10, Andy's f/r arms, and AandL steering rack.
I like ceramic for heat dicipation. Temperature is everthing, because I will run a hot lipo/bl setup. When I'm finished, she'll be a B4 killer.


Scr8p,
I can't blame you for being a hard-core, die-hard, old-school rc10 guy. When I first opened my B4 kit, I cried over what had become of AE. I was happy to be getting back into the hobby, but once I looked it over, I thought," WTF can I do with this? Not what I can with an rc10!" Then I started to put it together and came across things I didn't like.
My rc10b4 still sits , partly built, on my workbench. What is worse is, I have two B4s because I like to buy at least two of everything (for parts or back up).
Now, I am out to prove an aluminum tub rc10 can beat the modern competition in 2wd open off-road.

Thanks again,

shane

the gear diff won't fit in the stealth trans. the diff gears are all different sizes between the 2.25, 2.40, and 2.6 ratio transmissions.

if you are using a gold pan, stick with the stealth, and add the b4 slipper assembly to the trans. sounds like you have 2 sets of slipper clutches at your disposal.

in order to use the 2.6 trans, you would need to cut a rectangular hole in the tube, and fashion some bracketry to mount the trans properly.

[shane]

Has any company ever made an aluminum transmission case for the 2.25 stealth?

[jwscab]

there is some dirt oval company I think made one. I have seen pictures on this board somewhere, but that's about as much help as I can provide.

[shane]

Thank you sir. At least I kwnow they were made and maybe find one now.

I saw a thread in the tech section last night. I think it is pretty cost prohibitive though.....
