I have the prop washer on behind the higley prop hub[nut]. Behind it is the prop and then the base, behind it is another smaller washer then the engine itself. This is on a brand new OS.61 FX. I hand started it for a while thinking it was the electric starter over torquing things. The engine actually started backwards once! It seems like these should be reverse threaded or the engines + props should turn in the other direction.

So some folks indicated that I should fix other problems. Unfortunately, the only problem I thought I had was that the higley was falling off :-)... What else should I be troubleshooting first? Or, is this just a typical "tighten it more you idiot" case? I did some research and found that Higley actually sells an additional thin nut...I'm going to be kinda depressed if I'm going to have to go drive to east jesus for something that the Higley folks should just be sticking in the bag.

thanks for the responses
