Propeller lever does not react on assigned throttle quadrant in Twin Otter Extended Posted October 2 · Report reply 1 hour ago, FlyingAxx said: Now I have to look for a local replacement... Well, I just installed the 4bladewheelcargo model of FEDEX (definitely done by Tom) and it works properly. Unfortunately I don't have a hint where I got the D-IVER from (the source had been just a guess). Actually, I'm not in the mood for hunting a glitch. Thanks for stepping in. EDIT: I just re-installed the D-IVER and it works now as it should. I've still no idea what happened.
