So basically your telling me I wasted $70 bucks on the Hacker that's supposed to be so great. So what would the Hacker go in. I have been looking at the new E-flite Yak. Would that be a good match for it? So what is wrong with the Hacker 4900kv? Why would a another moter of the same type, such as the Himax or the E-flite Park motors outperform it by alot. I mean this is literally the worst flying plane I have flown as far as power goes?
