Just got the 523 today and hopefully tomorrow I can get it running. For the 1st gen maxx what can you recommend for me to do other than performing a .21 swap? I have the motor, mount, pipe, but don't have the flywheel nut...should I get a new traxxas nut or another brand?

I can't imagine it's any different that any other motor swap but fot thise that have swapped this motor is there anything I should know??

Are the bearings the same size for the clutch bell?

Thanks

Bump to add I have the pro .15 version and not the 2.5 so the engine accessories don't seem to mate well. Will I need the 3.3 engine parts or 2.5 or either?

well i don't have a tm523 but i upgraded my first gen tmaxx to 4908 spec(tranny, driveshafts, motor, 4wd) and all that i mentioned is made bigger and tougher to handle the trx 3.3's torque. So....start there! I would suggest upgrading to cvds etc...

Your going to hate the rb 523 you should not of got it. Send it back get the picco the rb 523 is just full of bugs!

My rb 523 had half a tank of nitro in it and the ****ING cod rod SNAPED!!!!!!!!!!

That is either mechanicle failure from the factory, or you were running it VERY lean. I think it was a dud from the factory though because it will take a few tanks of fuel to strecth the rod like that and then break it. Also the first few tanks are break-in so you really don't push the motor either. I don't think you could say the RB523 was crap from experience though, since you only ran it for half a tank. Plus it was a dud engine, so sounds more like a bad experience to me. I feel bad for you FrAnCioS.
