So I'm about to do the mod where you install an HPI 77mm dogbone and revo drive cups in place of the rear center drive shaft. Anybody done this mod? I've heard you have to install o-rings in the drive cups for some reason.....

Just wondering if anybody had any additional info...
 
Probably would. I''ve already recieved the dogbone, still waiting on the drive cups. So I'll have to see how it goes...
 
Well I got the drive cups and threw everything in. Everything fits fine and rotates smoothly as far as I can tell. I haven't gotten a chance to run it yet. I did put o-rings in the drive cups. It seems to give the shaft a little bit of cusion. Heres a pic..This is my first attempt at posting a pic so bear with me....
