The Feigao 12s is for 10-12 cells or 3s-4s Lipo. For 6cells, the Feigao 8s will run like like a Lehner 4200, but won't spool up as fast (heavier rotor, but more power). The Feigao 6s has been showed to have no real application, but would still be fast. The Lehner 5300 would be a very good motor. But there is another choice - the Feigao 380 (400) size motors. The 6s (380) would be an excellent motor. It is low cost ($50-60), but will spool up very fast since it is light weight. It will have speed comparable to the Lehner 5300 (faster maybe), but a little less torque. This motor also needs an adapter plate.
