the rolling. the mantra and mephisto all have different bearings.. I cant remember what bearings are in each but out of the 3 motors you need 4 bearings to cover the front and rear on all the 3 engines. but yes they are kind of pricy but ebay is a good source.. I have replaced 2 bearings in the 3 motors total and technically 1 bearing was in a buddies px5..

mantra front. 17011 rear 16801
mespisto front 17007 rear 16801
rolling front 17011 rear 16005
those are the bearing numbers. as stated before they semi cross over but 4 bearings needed for 3 motors.

17007 is the same size as the 17011 it just has black shields and 8 balls instead of 7. nova used it on the .28s around 2010

I have a RB motor that I just acquired. It’s a 9 port Rally Xtreme. Was sitting for a few months with what I’m assuming was fuel inside the motor. I took it apart and lubed it with after run oil and cleaned up anything I could. Put it back together and can’t get it to turn over at all. Took it apart a second time and heated it up in the over (at home) and it freed the motor up a bit where it now turns by hand (with flywheel on; but still tight at tdc. Rest of the movement is free. Bearings are good and free). The sleeve/piston has a weird click/thump at TDC. Pinch is tight, but seems off to me. Next move it to try a heat gun to get it to temp to attempt to get it turning on the starter box. I’m using an older 1/8th scale ofna blue top starter with lead gel battery that’s fully charged. I’m no pro, but I’m no beginner to nitro motors either.
Also trying to identify some parts on this motor. There’s an engraved ‘R2’ in a few places. Any clue who’s signature that is? also... replacement piston/sleeve/rod for this motor? Can’t find anything on Nova site. Not sure if nova internals are interchangeable.
