People seem to get the impression that a quality prop is expensive. If you mean carbon fiber maybe that's true, but excellent wood props are very competitive with paint stirrers:

BME: 22 x 8, 10, 12 - $25.00
Bolly: 22 x 10 $32.00 22 x 8 $32.00
Menz: 22 x 8, 10, 12 $25.00

These are prices taken off the BME and Desert Aircraft websites. What does one pay for a Zinger - $18 maybe $22? Is the aggravation of lousy performance worth $5 when the engine cost $600? Props REALLY do make a difference!
