Ok here's my question, I just installed a scale fuselage on my fly bar 450 pro and was wondering what it the best pinion to be using. Right now everything is still in stock form. 13 tooth pinion,150 main gear stock 3400 kv motor and 40 amp speed controller. Flight time is around 5 mins. Would it help to go to a smaller pinion like a 11 or 12 tooth. This fuselage seems a good bit heaver that I would like. Just wondering what you guys think.
