Metal Prop vs. Wood Prop
I have a wood prop on my Taylorcraft and the GPS says it's slow, at around
65 kts. How about a discussion on the relative merits of wood and aluminum props. I understand that wood is easier on your engine but the aluminum prop is more efficient. Another thing I notice too, especially on the O-320 and O-360-powered RV's is that the wood prop is so light it has little flywheel effect and if you don't have your timing retarded, it will kick back in a heartbeat. I figure the wood prop on a Van's aircraft is for CG. I think what I'll do is buy an aluminum prop and try it for a while. I couldn't keep up with a DCO-75 last week and it was a little embarrassing, since his engine was sick. But he had an aluminum prop. |
