I was flying the other day and in midair, my prop came off.. my enging immediately screamed to 5 billion rpms and died.. luckilly the engine is fine but I lost my prop, the nut and the plate that the prop sits against. (15.00 and 2 weeks of waiting) I got the idea to use 2 prop nuts that I picked up at wally world for a dollar ot hold teh prop on.. Just tighten one down and then snug the other one against it and I dont think I will ever have this problem agaian.. does anyone else do this or am I just a genius
