I'm new to this site and found it my searching for CEN genesis problems. I have had nothing but problems with my genesis since break in! It looks like to me that there was definetly no enough R&D in this one. I've got the new gears installed. Now the pinions break! Fixed that, now the main shaft in the transmittion twisted the nut and threads right off! WHAT'S NEXT??? Was anything on this truck made to withstand 5hp at all? I haven't even got to go off the asphalt yet! After break in was done, I have been able to run it two times for 2 minutes per time. I can't explain the dissapointment after spending break in time and customizing time and $600+, to have to spend more money to break it again and again. It's for sale I guess if anyone is interested, I can't afford the repair bill to fun ratio on this thing. At least not when I can go out and thrash my T-Maxx and walk away with no problems.
