I tried running the R40 today for the first time, and it reminded my why I got out of nitro years ago. Anyways, I was breaking in my O.S.TR today, and one of my many problems was trying to get the car to move. It seemed like I had use full throttle to get the clutch to engage. Once it did engage, it didn't seem like it was holding too well. Did I do something wrong when I built the car?
