What is success?
Higher average speed?Faster acceleration?Less drag?Less vibration?Less propwalk, especially in reverse?Good solutions range from a few hundred to a few thousand dollars, depending on your preference, and budget.For instance, we got another 0.5 knots of speed, reduced vibration, and reduced propwalk from a rebuild of the prop that added winglets at the end of the blades. Our cost was $170.DavidLady Lillie
