I had a similar problem with my latest v3. When I first calibrated it everything was fine then after a few mins of running it started cogging and stuttering. I switched the receiver from my Rustler (Futaba R153) and it seems to work fine with it. I noticed that when it was acting up with the first receiver (Futaba R133) that it was more like a glitching problem because I could see the red LED flash when I was giving it forward throttle. I also switched channel 1 and 2 to see if the receiver was fubar but it's fine.
