Even though I posted this over in rcgroups, I thought I'd throw this out here to you guys. I ran a couple of 2s's in my cycle. The throttle wasn't smooth at all, kinda that jerky, cogging when putting on the throttle. My Aftershock and mini Revo do this sometimes so I figured it was the same situation. Well, set the bike down and got it going. It got hung up in the grass so I put on full throttle and the jerking just kept continuing. Finally brought it in and tried another lipo. Same thing. Tried it holding the bike with a 3s, same thing.
I called Duratrax and they are sending me another speed control. They said putting a 3s on the bike is really pushing the speed controlo. I took the temp of the speed control last night just holding the bike and trying a 2s. The speed control temp after just a minute of trying to "go" was around 130 degrees. Pretty fast warm up for just being held up. So hopefully it's the speed control that is jacked.
Is there any way for me to test if the motor is bad? I guess when I get the speed control from Duratrax and it still is a problem, that will be my next call them. The tech from Duratrax told me that a no load test on the motor won't tell me anything (just pulling the pinion back from the spur). It spun freely without issue when I tried that.
