I realize keeping it simple may make it difficult to answer the question, but basically, I have a DF26 with a setup pushing around 29K RPM. To keep the amps low on the motor with a 4s setup, I am looking at possibly a X632 or X432 size prop. I tried the X637 cause I had one handy and the motor could not handle it. Temps were too high. Calcs seem to like the smaller 32mm props, but would I be wasting my time?.....
