So, I have been flying for about a week now and today my motor would not get up to full speed. I took the plane apart and noticed when I accelerate the rudder servo moves a little bit. The rudder servo is mounted on the receiver and I'm wondering if the receiver may be faulty. Im pretty handy but this stuff is new to me. I'm getting about 3.8 volts to the motor but the pins are so small I have a hard time keeping the probes on to monitor the voltage to see if it is fluctuating. Also, the motor won't turn unless I spin the prop. After the initial spin I can move the toggle and it responds ok up and down until I take it to zero throttle again. Any suggestions?
