RE: Weird glitch.
I was having a lot of "uncommanded input" problems with my Tiger2. It would roll and pitch ubruptly while flying straight and level. Ireplaced the radio, same. Replaced Rx. same. One day the plane was on the starting bench, engine running, and ALL the servos went crazy. A friend looked it over after I shut it down and found my EZ-link on the throttle. He told me to get rid of it. Idid and the problem went away.
Ihad used that system on all of my planes, and all of them would suffer the intermittent "twitches." 3 of them went in the trash because of it. Idon't use it any more. LOL
