[NSRCA-discussion] Prop Recommendations???

[Dansy44]

With A50-16S that I have in my Sebart Miss Winds I run 6s with a 17x10 with 70'ish Amps.....never did check the RPM I just when with the speed/presentation I wanted.....I did find the model too fast for me with a 16x12 and lacking in the vertical.
