“I bought the three F4 gears as a substitute for the weak FlyFly F100 kit plastic gears. The knee shock absobtion system requires only requires a minimal cutting out of the gear well on the aft side of the wheel. The rest fits perfectly regarding size. The spring is exactly what it should be to absorb heavy landing forces even with a 6S5000mah battery in the frame, but keeping the gear straight during normal operation, effectively hiding that it is a kneeling system. Everything is made very strong and operates like a charm. The wheel looks very scale and the hole unit is very suitable for operation from grass fields.”
