Hello again,

I have just installed my servos and receiver in my SIG 4* 40. When I switched on the transmitter and then my switch to the reciever everything was fine. But then I reversed the sequence and my goodness the servos went crazy. Jumping around with short jerking movements almost appearing to break the control puch rods. I am a beginner at this and I have went back through my radio manual but nothing that I could see for trouble shooting this situation. Can anybody share their thoughts regarding this.

Thanks,
Lamar

There is nothing wrong with your system. Always turn your transmitter on first. When the receiver is turned on without a signal on its specific frequency, it will respond to atmospheric interference, stray signals, radio noise, and even your body moving close to it.

Sounds like your first plane Lamar,,,this probably isnt a good plane to start with unless you have a LOT of help...dont try it on your own, please.....Rog

Thanks for the advise...This is actually plane number 2 (1st one is the trainer). The trainer's radios doesn't seem to go as crazy as the 4* does. I was afraid that I might have a defective unit or something and was hoping for a little insight.

Thanks again.

Have a good one

One other little ditty here is whenever you turn on your transmitter, Extend the antenna a little ways out. Don't have to be all the way but just a bit. This is only if your not flying and just checking things out or something or maybe at home

The radios I have don't normally care whether I turn on the transmitter or receiver first. If I turn on the receiver first they just sit there quietly waiting for the transmitter. However, a couple of my receivers go absolutely crazy if I turn them on while the charger is plugged into the wiring harness.
