Oscar, I too have been surprised by my flop.I routinely forget to lower it when I start the engine and the propwash will"wang" the flop down hard. Each time this happens, the forces in essencewant to pull the hinge screws out. I had to retighten them after onlythirty hours or so due to my forgetfulness. I used longer screws, a littleglue on each and added more foam padding so when it bangs down, I still haveto pull it a little further into the foam to get the latch to catch, AND I'mtrying to be more careful. Now I only forget about 25% of the time.DouwePs. Does anyone know anything about dynamically balancing a prop???________________________________________________________________________________
