Good point. The LT25 uses bolts as the wheel axles. Its hard to keep the nuts tight in the correct position after a few dozen flights which results in the nuts moving in on one or both of the wheels acting like the brakes are on! I got fed up of the constant adjustments and went to a standard wheel axle with wheel collars. The plane, the way I built it is too good to give up. I put minimum dihedral in the wings and made it attachable with four 10-32 nylon bolts and put an OS 32SX on the nose. Makes the plane easy to fly in the wind and has lots power. I can take off in 10 feet if I give it full throttle and full up elevator! [8D]
