when I removed the flaps and droops the top speed and fuel economy went up. used to get only 10 to 12 min out of a tank now its more like 15 to 17 min if I am easy on the throttle rolls and turns are much quiker. also the glide rate is smoother found the landing speed is alot higher not so floaty on approach. so go ahead and take them off you can always put them back on
