Hello, my name is Norberto and I'm from Argentina. I have a poor english, I hope you understande me...

I have two aircraft with identical configuration:
Futaba T10CAG transmitter.
Elevator Futaba S3010, rudder Futaba 3010, ailerons Futaba S3010 one on each and throttle Futaba S3001.
Futaba 12" extensions in each aileron servo and Futaba 6" extension in receiver for each aileron servo.
Futaba R617FS receiver.
Hydrimax 4.8V 2000mAh batteries.


I noticed that the ailerons, mostly channel 1 has a malfunction. When returning the stick to the center, the servo exceed this position but immediately it back producing a kind of bounce.
It has also happened that the servo in channel 1 stands still when I move the stick to one end and it moves later.
It has also happened that the servo is dead as if disconnected and I can move with my hand. Then reacts and it is impossible to move with the hand.
In the video I'm using a NiMh battery 6V 1600mAh and the problem gets worse.

Usually, such a "bounce" is caused by dirty connections. If you don't have a good connection, then the wiring will not deliver full voltage to the servo. Unplugging and reconnecting the servo several times usually cleans the connectors.

When you mention that the servo sometimes has no holding power, it means that it's getting no power. We'd suspect the wiring has a problem somewhere.

Hello Bax, thanks for your answer.
I'll check the connectors.
Yesterday I noticed that after a couple of flights the problem disappear.
Anyway I'll check the ailerons servo connectors inside the wing.
