eflite outrunner and hobbylobby airblaster...
I have a Hobby Lobby Airblaster with an E-flite 400 920 kv outrunner motor. The prop sizes recommened for this motor range from 9x7 to 11x4.75. I have a 10x6 cam prop which works nice and has great vertical performance, but sometimes I would just like a little more speed and to conserve battery life. If anyone could run these numbers through a moto calc program of some kind(I'm not familiar with how these programs work) and tell me if a 8x8 or 8x9 or 7x 10(if anyone sells these sizes) or what my other options are. I'm using an E-flite 20 amp speed control as well. One more thing if I am goimg for speed should I go with an e-prop or sf slow flyer prop? Any help or points in the right direction would be greatly appreciated.
