I have a fairly new OS CV-RX(s) .18 engine. The crankshaft broke for some unknown reason. I have an old TRX.15 that came in a Traxxas Rustler. Do you think it's possible to use the TRX crank in the OS? Thanks for any help.

i doubt it but even if they would fit it would probably mess up that engines powerdont try and make a ghetto bandage for do it right also doesnt that engine under warrenty

Well I got it about a year ago and accidently threw away all the paperwork. [&:]

Its very unlikely that the crtankshafts are interchangeable, i have 2 .12 engines and the crankshafts are completely different.

If you can find the correct part number for the crankshaft for your engine, then you could just order that part though....
