I have a YF-23 EDF, made by LX. The front landing gear came off on a landing. There was NO damage to landing gear, nor to plane. Before I re-installed the front gear, I checked to see that it worked. It does work, however, it now goes in the opposite direction of the main landing gear. When the main gear are going up, the front is going down and vice versa. Is the problem with the retract controller, or the front gear? I changed the main & front gear positions on the retract controller, but it made no difference.
