Thanks GB!

Flew the belly landing configured version of the venerable PZ F4U-1A Corsair on its first and last fighter sweep mission powered by a very successful four (4) bladed prop that is intended to be used on the upcoming retractable landing gear equipped PZ P-51 "Dallas Doll." The landing into a "reasonable looking " stand of grass was made with a little more than 1/2 flap deflection into a mild wind in 80 degree plus air temperature. This test flight proved that four bladed props are a dumb idea for big park flyer belly landers. Also proven was the strength of the two de-pitched and thinned Master Airscrew 12X6 props modified and glued together to make the four bladed prop. The blade that evidently took the greatest impact force on the "crash landing" was bent back noticeably and required some forward bending to make it track with the other blades.

With scale models more than two blades are not needed. For purely aesthetic reasons it has been great to learn that fine tuned three and four bladed props can be made very competitive performance wise with the best two bladed props.

Rolling in to attack.

Out.
