Hi Fellows,

A friend of mine bought a Giant YAK 54 powered by a G62, I did the test flight on the bird and after 5 minutes of flying time the trothle and rudder started make some glitches, it was scary but manage to get it safe back to the ground. We check the connections on the trothle and rudder servo and everything looks ok. After disconnecting a home made engine kill swicht we flew the plane again and same results, it glichtes again.

Any suggestions or advise where to look are Welcome,

Daniel
