For my next airplane I'm planning on using a folding prop to reduce damage during landings (as my motor is mounted on the nose). The folding prop looked smaller (the actual blade-moving air portion) and I was also a little concerned about the folding blades becoming unbalanced or not fully extending.
I decided to throw three different kinds of props on my motor testing tower and find out what their performance really was. I tested them for amps consumed, watts required, airspeed (at about 1 ft. away from the prop) and of course, thrust.
The folding prop did just fine, and at least matched the performance of the others. I have no hesitation of using on my MTP3.
