I got 3 JR NES-8300 Super Servos in my new heli connected to my Futaba 129DP RX, when i turn the power switch on the servos turns alot to on side before turning back to neutral. Otherwise they work just fine. Why dos this happen to just to the 8300 servos and not the other ones (1 JR DS-8425 - 1 Futaba S9251). This happens with the TX on or off.

I believe that some of the JR digital servos do not like the momentary logic high pulse that the PCM Rx sends when it is first powered up.

A similar problem occurs when the Futaba GY501 gyro is used with some JR digital servos. Gyro initialization sends the servo to an extreme position for five seconds, a deadly situation.

Frankly, you would think that JR would fix the firmware in their expensive digital servos to prevent this.

Servo Problem

I am going to change the 8300 servos for new DS-8425 (11kg) for aileron elevator and throttle. It is an overkill but i don't give a F***

Next time i will only by Futaba, 9Z WCII with digital servos. JR can kiss my hiny. And the 10X can suck my d***
