If X propeller at Y rpm produces Z # thrust, then we could all post our observations/measurements with various props. Because these thrust measurements should be repeatable, people wouldn't need a "thrust calculator" program. They could just take their tach readings and compare it to postings on here of the same prop/rpm and it should give them thrust estimates. It wouldn't matter what type or size of engine turned these readings as rpm's are rpm's.

This would be a continuous listing of thrust produced by members' engine/prop combos. Of course HONESTY would be the main ingredient. [X(]

RE: Thrust Chart???

OK, I'll post some #'s. These thrust figures are from a search of this website and are actual "fishing scale" measurements. No thrust calculator #'s here.
