I have a Sirio .18 drop in for a Maxx. The problem I'm having is the guy who had it before me cut the pilot off the shaft!! (why..I have no idea :crazy: ) The problem is I haven't been able to find a pilot shaft adapter to fit.

The threaded part of the crank is the same as a 2.5 crank so...

the pilot for the .15 won't work (thread size way too small)

I bought a New Era pilot shaft for a .21 conversion (uses 2.5 clutch, flywheel, etc.) and apparently standard .21 shaft tread is still smaller..(really close, but still doesn't fit)

:confused:

Can anyone help me out here??

there is a traxxas part to extend the shaft, I've seen it. I can't help you with a part number though sorry

Yeah, the Traxxas part is for the pro.15 stlye engine, it works for conversions like the O.S. .18 cvrx when you have to cut the crank, I looked at that one but the thread size is different.

I know Ofna makes a .21 pilot shaft but its 1/4 x28 and the Sirio shaft is more like a 24p or maybe metric?

This is the engine I'm talking about...

I've owned 3 of those Sirio's..... I just wonder why the last dude cut the crank :confused:
