Sam's prop actually measured 76 inches long (if I remember right) which is quite a bit longer than I would want to run on a nose gear equipped RV. A 76" prop leaves very little clearance off the ground and will undoubtedly result in a considerable amount of blade tip erosion over time. If my IVO prop doesn't really work out I think I will give the CATO 3 blade version a try since there are quite a few RVers flying it and it will get the tips off the ground a bit more...at a cost of a couple knots of top end of course!
