servo jitters
 

My new Great Planes Ultimate has digital servos everywhere, with Futaba 8 channel 2.4 receivers ( two of em ). Both of my elevator servos jitter so bad that the plane is not flyable. The servos are 9351. Nothing seems to help this. Do I need sound suppressors on these long servo leads ? Any other solutions ?

Can you let us know which receivers you are using?

Krista, thanks for replying. The receiver is the 8 channel R6008HS and the servos are the 9351 digitals. I've replaced the servos, no help. I reduced the battery power from 5 cell to 4 cell, no help. I tried the receiver on "normal" and High speed, no help. The servos jitter in neutral and along the full swing of the servo. They jitter so hard that the plane is not flyable. My plane does have three long leads with three servos in the tail, about 40 inches long. The servo wire is heavy duty. The wires are soldered where the connectors occur; there are no plugs along the way. The aircraft tail does have flying wires connecting the rudder to the horz stab and the stab to the bottom of the fuselage. The wire is Kevlar, and the connectors are plastic. The radio is a 9 ZAP. Please help !!!!!!!

Try connecting the servos directly to the receiver without the long leads. If they don't chatter, then your leads are too long. You're getting too much voltage drop along the leads.
