Friend in the club I fly in tried to fly his airplane without pluging in the wing servos, the airplane refused to defy gravity. Went in nose first. Airplane destroyed, DL 50 did not come out either. What suprised me was eng mount held up, mounting lugs on crankcase all busted. (this was a version one eng.) . He spoke with Bob @DL USA and ordered the version Two crankcase, had to order both front and back. He said it was an easy swap of parts, had to drill and tap the back half for the pressure nipple. Good to go again. DL50 NEVER SAY DIE.
His new airplane is the lanier edge 540. Can,t wait to see how the plane flies with the DL.
