I'm using an EMAX motor, Castle 75A ESC, 5s 4000mah 30c, HS-225s, 15x7 or 15x8 Vox and Xoar props. My SBACH weighs 5.26 lbs AUW.
Flies great but when you harrier it likes to wing rock a lot when it slows way down, so you have to be constantly on the throttle and controls. I fly it inverted, about 500 feet in a knife edge, and it does more than I am capable of.
I just changed my exponential from 30% to 60% at the advice of a fellow 3d flyer. He says it will be easier to control. Haven't check it yet. My TX is in for repair.
