RE: Dynathrust props....how do you rate them
I have been flying the dnya's for several years on a ST3000 and 2 ST4500's with no problems. 20x8, 20x10, 22x10 sizes.
prop rpms 7200 up to 8800.
I have rock pits from the gravel on the runway in them over time but they have been good for me and priced reasonable.
They break when I dumb thumb it and strike the bottom edge of air.
my 2 cents
