Well I tore into the landing gear situation, apparently the shaft that drives the main landing arm from the gearbox broke inside the landing gear arm and it also broke off one of the two corners of the gearbox where one of the lugs is that keeps it from spinning when power is applied sooo, for now I have ordered a new main landing gear with gearbox and motor to replace the one side. Guess my dual setup will go on hold for now but I will have a spare motor and gearbox. When I get the old leg out I'll look and see if I can rebuild the upper end for a spare.
