Remember reading that safety bit? Well today I started working on a plane to see why the one wing servo "dithered". I removed the prop and found out the servo connector on the receiver was a bit loose. As I swung the wing around, the wing hit the throttle lever on the transmitter! instant full throttle! I grabbed transmitter and hit the throttle cut. No problem or damage other than my nerves. Yea; I should have had the throttle cut already on, but the missing prop means I don't have red stuff on the prop or visiting the ER.
