Would one of you kind souls measure the dimensions of a slipper or Hydradrive top shaft that has the top gear keyed to a roll pin, please and thank you...?! It's for a secret project that may or may not include mutting up a Lethal Weapon for an even more mutted up Ultima Pro XL
I'm really curious about the distance from the roll pin to the end of the shaft, how far from that end of the shaft the slipper hub flats are. Also, I think there's a circlip groove, that would be good to know too.
My bad. Forgot it was flat on both sides and not D shaped.
It was the 3,2 measurement i was loking for. 1/8" i guess...
I have most parts for a XX slipper as spares in my old box of rc stuff. Would like to fit it to a LRM transmission but is missing the top shaft. Thinking of having one made. So this thread is very helpful.

I installed a XX Double-disc slipper (could also do single disc/hydradrive, whatever) on one of my LRMs, no mod needed, just used XX stuff I had laying around. Now I know the early ones weren't slipper at all, but the later ones (like this one) were made for the slipper. You just need a Losi A3120 top shaft... if you can find one.

Yes...
Both my LRM:s are non slipper.
The idea is to use your measurements in combination with measurements taken from my non slipper shaft and see if I can get one of my machinist friends to make one. It might cost me a couple of beers.

Sorry adam lancia for stealing your thread!
It sounds very interesting using a Lethal Weapon in an Ultima with a Losi slipper.
Keep us updated!
Can anyone ID this top shaft in the B3 I'm building? It's aluminum, and there's a stud that threads in for the slipper hardware. I can't seem to find anything online. Thanks in advance.

Yeah, I've got the manual.
I don't know if I need to change it. It was assembled when I got it, so I'm just going to slap it back together. I was curious if anybody knew what that top shaft was, and if I possibly needed different spacers to shim...
i have the b4 top shaft for my stadium truck now my son wants to get the other truck i have going instead of switching tranies does the b4 topshaft fit the stock 10t tranny or just the stealth.
i wonder how hard it would be to mount the b4 tranny it...

i do have a stealth but i also have 2- 6 gears as well.
i switched the topshaft and the slipper and spur worked great.
with brushless my son cruised it around the track the other day.
Have been out of the hobby for about 18 years just now getting back into it.
Looking to swap the top tranny shaft in a B4.2 with a B3 top shaft. Can this be done?
If this can be done I will buy a B4.2
Thanks for any help.

I did it the other way round so I could run a B3 with a B4 slipper for a brushless setup. It was a straight swap so I can't see why you couldn't do it the other way.....
Hello all. I've been doing some casual club racing with my old T3 just to get some extra wheel time. Anyway, I want to put the T4/B4 slipper/top shaft on it.
I've heard you have to shim up the topshaft to make this work.
For those that have done...

The manuals are on AE's website. Same about of shimming as stock.
I put a MIP top shaft and dual slipper on my T2 without issue.
After some help to save my sanity. I found this Steel topshaft at home and cant work out what its for, The best guess i have is that its an aftermarket B4 top shaft ??? As its the same length also. However, it has a thicker shoulder up to the gear...

Ignore me, sussed it now....... :)
Wait what was it?
Probably something to do with the machined spacer instead of a bearing surface
I recently stripped apart an old stealth out of my junk box and it had a really nice ti top shaft in it! I was curious who made them back in the day, and if they are still available? It came out of a trans that was in an old dirt oval car so maybe...

the plastic idler with metal top gear and diff gear would be the most efficient, strongest and maintanence free. if you decide for all metal you need some good lubrication that stays on the gears.
Is there a way to adopt a b4 style top shaft to a 64 pitch for use with a thorp 64pitch gear set? Were the top shafts and idlers for the thorp 64pitch gt and rc10 stealth the same across kits?

It may be possible to press the gears off and swap them. I'm honestly not 100% sure though.
Are there any threads here on that? Would I just try and torch and hammer off the gear of a associated steel b4 top shaft? Are there any 'blank' b4 shafts?
