ok i have a question for everyone i need some help figuring out this problem i have with my radio/esc/servo. I have a ko helios, with a hi-tec 6965 servo, and a quantum competion 2 esc. everything works fine with this combenation. I have another car i am going to use this JR900s servo in. when i plug it all in and turn it on it looks as if everthing is ok, but when i have the throttle at any position, and turn the wheels, the motor pulses and loses power. i have no idea what is going on. if anyone could help or give me any ideas of what to do that would be great because i am at a loss. Both servos are digital servos.
