found the glitching issue, need help solving it

[kufman]

FM and AM are in the same carrier band, both are susceptable (sp?) to mechanical vibrations. This is supposed to be the advantage of the newer 2.4GHz systems.

As for the problem. does you antenna wire run under the chassis and then up through the antenna mount? Is the receiver padded from the aluminum chassis? I am with the guy above who suggested trying a regular receiver pack once to see what happens. be sure to remove power from the Ubec when you do this experiment.
