OMP edge prop change=tailslides.
i never did like the 12.25x3.75 prop. try a 11x5 apc.good pull and response. i just cut down a zinger 12x4 to 11.5x4. havent tryed it yet. the 11.5x4 apc was to slow on response but pulled real good. the zinger 12x4 responed good but the motor wasnt pulling that good. im hoping the cut down zinger will work.
i never though about responce till i put it in a 1 ft hover. i learn real fast. any way good luck and let us know what you think.
