I just put a 26CC engine in my plane. I have found that when doing a range check (72 mhz) with the antenna down and engine NOT running, everything works well up to 100' or so. When turning on the ignition switch, I get glitching of several control surfaces around 70'. <span style="font-size: larger">Can't figure out why when the engine is not running</span>. Any thoughts or potential solutions to eliminate glitch?

Thanks.
