I have a twin 70 mm 12 ch mig 29 i threw these in. It took me about 6 hours to carve wood brackets to angle these so they would fit into the fuse. everything is in and out for a taxi run. as the plane turned right or left the rear wheels rotated on the shaft so oh well... throw some glue in there and make sure it doesnt do that. one was good to go but left leg allen key screw stripped on the first attempt to remove. Now I have a plane set up looking pretty but cant turn left or right otherwise the whole left gear rotates off center. I have had these screws strip before on me. I have done about 50 cycles just setting everything up to get the doors and fit just perfect and they seem just as solid as the first cycle. Each gear does have play to them as I can wobble the whole bird while its on the ground.Made pretty well. The only problem is front wheel spring is way to weak - folds completely at 400g while should be at least 1.5kg. Fits perfectly into LX MIG-29 even by having 1cm bigger wheels than stock.je vai les mont sur mon mig 29 lanxiang
