Will a Dynathrust prop ruin my Zenoah engine ? The Dynathrust props are a bit more flexible than wood and APC props.... ok maybe a lot more flexible [X(] I remember someone telling me once that a prop that flexes in flight can ruin the bearings in an engine Is this true ????

I know Dynathrust props suck, and that they tend to throw blades, but I just got a new G-45 and put it on a new airplane I jsut finished I really want to test fly this plane tomorrow and the only prop I have at the moment is a Dynathrust 20x8 [:@] , and for a the test flights the dynathrust would be perfect as I dont mind if it gets broken I just need to know if using that prop is going to harm my engine ????
