Nope. It's the Savox. That being said I still run Savox in all my vehicles. It's even an issue with my rx8, however all I need is a cap to make things work, unlike mmp I had to have a external bec. I ran a few different servos with my mmp and spectrum and had no probs. but take any one of those 3 items out of the equation and pribs solved. I battled this and trouble shooted for over a year.
