[NSRCA-discussion] Futaba ZAP WC2 transmitter problem

[Peter Pennisi]

Hi Karl,

Great to hear from you again. I wouldn't mind your weather at the moment. It
is so hot down here that you can't stay outside let alone fly.

I have checked the loom and all is OK in that department. It appears that
the pot may be rotating so I am investigating this theory.

Cheers,

Peter

  Peter,

  Hope every body is well down under.
  I had a similar problem where the servo would jump at the very end of
  the stick travel. All it was that the loop in the wires from the pot was
  to tight and at the end of the travel would put some strain on the pot
  connections. I increased the amount of the slack in the wires and
  that fixed the problem. Don't know whether that might be your problem
  as well or not.
