I bought these to experiment with on my old Bixler 1 with a 2200kv motor, I expected them to be in similar performance to a 6x4 prop, but they're not, compared to a normal 6x4 prop on a 2200kv motor these are MUCH slower in speed, I know these are intended for quads etc, but I believe they are more like a 5x3, using them as normal props and any speed gains will only be made with high KV motors, these are NOT in my opinion as fast as a normal 2 blade 6x4, I expected with the 4 blades i would get similar performance to a 6x4 but no.
