I had a small crash into my tower because I wasn't paying attention (then panicked) which burned out one of the ESC's in my Phantom 2 Vision plus ver 3. The ESC that I received was a new 2.1 version but all others in the Phantom are the non labeled v2 version. Has anyone noticed any problems installing just one of the new ESC's? It almost seems like one of the motors is now over spinning and causing it to tip forward then kind of circle on the pavement (glad I have the prop guards on for the moment). I've tried an advanced IMU calibration and re-calibrated my sticks in hopes that might be the cause but that didn't help. I've had my son hold the Phantom while I try to apply a small amount of power and you can clearly see that one corner lifts more than the others. I tried switching to Atti mode to see if maybe it was a GPS issue but it seems to react the same way. Does this sound familiar to anyone? I'm a little bit baffled.
