Ok so I have bought 2 stealth buggies and 4 rc10t's. What is the ratio on the trannies? I am looking to make 1 runner out of each and 1 shelf queen out of each.

The trucks trannies need to be rebuilt and I've heard that the ratio inside needs to be updated to be competitive is this so?

Where do I get the RPM case at? and the gears to change the ratio?

what do I need to update the slipper to the new style?

Sorry but i'm just getting back into this.

I ordered the Delrin a-arms for the buggy and the RPM hubs. I'm working on the buggy first.

You can get the RPM tranny conversion at Tower, here's the link.

which slipper setup do you want to update too? b3/t3, or the b4?

if you want to update to the b4 slipper, you won't be able to use it with an rpm trans conversion. the topshaft is too big (more teeth). using it in a 2.25 stealth trans will work fine. you'll have to use a b3/t3 slipper with the rpm trans, or the original slipper from a 2.25 stealth.

what i sthe top shaft that comes in the conversion?
and on the 10T what ratio does it need to be brought to? and how i see people putting the rpm conversion on it too.

The RPM conversion brings the ratio to 2.65:1 which is better suited to the larger diameter truck tires. The stock Stealth top shaft comes with the conversion but RPM did make a conversion that came with a Losi top shaft which coincidentally fits the current B4/T4 slipper/spur assembly. Good luck finding one of those though, they've been discontinued for some time now.

so what are the stock ratio's for the stealth in the buggy and truck?

2.25:1

ok i think i am now lost. you said the rpm conversion brings the ratio to 2:65 but after that said it came with a stock stealth shaft. did i miss something?

also i saw user aeiou do the rpm conversion to his project buggy?

It comes with a copy of the standard stealth shaft just with a different number of teeth on the gear. Just means it uses the same slipper clutch mounting as a 2.25 stealth so you can only use a slipper from a B3 or earlier.

the 2.65 rpm trans use a topshaft with less teeth as compared to a stock 2.25 stealth trans. which is how it gets it's lower ratio. that is why the rpm case comes with the topshaft. you use all of the other 2.25 stealth internals to complete the rpm trans, though.

I see. so is there a way to go to the b4 tranney or slipper setup? will the b4 gears fit in our case?? just looking for all the options. thanks guys when i can i will post pics of all my cars. about 12-13 cars/trucks

with a stock stealth transmission, the b4 topshaft and slipper is a direct replacement.

you cannot use a b4 topshaft on the rpm conversion since the rpm tranny uses a different gear on the topshaft than the b4 does.

gotcha!!! thanks
