Hi chaps. Today I tried to sort out my receiver. However I am getting a lot of chatter from the other servos when I engage one servo. I have tried all sorts. I am making sure that the transmitter is turned on and the sticks etc is mid position before I switch on the receiver. But still get chatter no matter what I do. Can anyone help, thanks.

Hi Terry, how many servo,s are you using? And what operation do they do?

Have you/can you try another battery to power the RX/servos - my hunch is that that may well be your problem

Hi Terry have you tried re-binding your Tx ?


John

Hi chaps. There are servos for the rudder, water pump and dive planes and one speed controller connected too the receiver. It’s a futaba f14 navy transmitter, and I am not sure binding is needed on this set up, it worked ok on another model. I will try using another battery and see if things improve. Will keep you posted.

Hi Terry,your Tx has christals, not binding buttons or switches or plugs.I would remove the christal from
the Rx give it a clean and refit see if that makes any difference if not try another Rx if you have one.
I presume your batteries are fully charged are you using a magnetic on off switch in our system?
Have you checked all switches are closing properly and you don’t have any voltage drop after them.
I repaired a friends sub recently and the main switch to the Rx had corroded so it did not switch properly.
Just ideas, hope they help

Found the fault. The chattering servo was linked to a second servo. Removed the second servo and all ok. They must of been talking to each other. Michael

Chattering servos is never a binding problem, and very rarely anything to do with crystals.  The symptom there is that nothing happens.
A servo on channel 1 (usually steering) on pre-2G4 sets is often interference being interpreted by the receiver as a valid, but varying, signal.
Servos misbehaving is often caused by dud power, or, in a large set-up, by an overload messing with the receiver voltage supply.  A poorly servo might puta big enough demand on that supply to cause the voltage to drop.  Since servos rely on stable voltage, they will dither in sympathy.
The servo causing this problem "might" be OK on its own, but "might" be dragging the supply voltage down.

Thanks will test the servos later for voltage drop. Good information
