HQ Prop R37 5137 5.1" Racing Propeller (2CCW+2CW) - Poly Carbonate - Choose Color

A little more ridgid for higher speed turns without prop washout

HQR37 prop

The best props for my build. Very durable

Happened to like the R series

I am an advocate for the J37s but the R37s have a little bit more juice if you need on my lower kv setups
