RE: OFFICIAL HPI RUSH / EVO THREAD
OH I forgot about that tiny detail. you need to put a washer or two behind the flywheel otherwise the pilot shaft will bottom out before getting tight. I took the pull starter off and the haxagonal one way bearing off and held onto the crank shaft with a vise grip with cardboard in between, as not to damage the crank shaft. Very important to take off the one way bearing and grab the shaft only. If you found another way to hold the crank then nevermind.
