Erh7771: I had a old 90mm FlyFly fan that I modified to cut the fan by removing one half of the fan house, and I Fan was in balance after it was cut.

St. Martin: It is only natural to loss thrust when you remove areal form the rotor regardless of the shape of the blades, but I must emit there is a limit to how much you can remove from a scimitar shape... After cutting the fan I ended up with a pitch of just over 45 degrees at the tip, so it is not to bad.

Extreme_RC: The reason for me is to try to gain airspeed not just thrust, for that I needed more power giving me a need for a bigger motor and a more power full rotor. Sense the CS 90 rotor is build more vigorous it is the first choice for me. And when cutting it down the centrifugal force work with my witch allow me to up the rpm's.
