so i hooked up all my servos to the rx again and i noticed that the small clicking sound goes away when i move the tx about 6+ inches away from the servos. i guess having the controller to close cause them to not center? what causes this? i moved the sticks and the arms moved like they were new.
toothman..... Putting the transmitter antenna that close to your servos is not a fair test. All electronic devices have RF Suspeptability which is a term that describes an RF signal or multiple signals getting into the circuitry and causing the design to not work properly. The level of radio frequency energy can become too high for circuits to work properly. Move your transmitter back several meters and than look for proper servo operation.
With the above said, if only ONE of your servos exhibits this clicking noise with the transmitter up close, than I would worry about an RF bypass capacitor that may have become loose inside the servo, increasing that servo's RF Suseptability. They should all behave about the same.
After a crash, check servos for physical damage, check the wires carefully for nicks, check the connectors for cracks or problems, and then slowly cycle the servos from one end to the other. Not worth taking a risk if anything is not feeling normal.
