I'm getting 20 minutes of flight out of my superstar right now. I know that is plenty of flight time but i want more. I know the jet industry <both r/c and real> use a sort of Kevlar wing tanks. Could i put theses in my trainer? I'm takling little 3 oz. tanks in the wingtips. I know it'll weight her down more but right now its only a little under 5 lbs. is this possible? Any info appretiated.
