My R spec busted too. It ran fine the first 5 times, then it seemed like it had to "warm up" then it became very particular to the placement of the motor. I checked to make sure it wasn't the battery so i put my 2.2 back in and it ran fine. I tried to contact Tinyrc through his profile on Sunday and haven't recieved an email back.
Turns out that the motor isn't busted. I was getting ready to send it back so I wanted to check it again to make sure, and it ran. I had not messed with it in about a week. The problem was that the chassis was cracked where the heat sink clips in and it wasn't holding it down a much as it could of. I also bent the the metal surface that touches the end of the motor, which might of helped too. So to you that are pretty new to this too, the R spec seems to need a more solid connection than the stock Tomy motors because the 2.2 still worked fine with the cracked chassis.
