Nice plane, for the money. I fly it on a 800 mah 2-s Lipo. Easy to launch flies right out of you hand . Pretty fast amour 50 mph or so . Goes straight up for awhile. Stable and smooth to fly. Goes where you point it. Keep the aileron throws to about 1/8 in movement each way. You'll be surprised at how fast and it is. More of a speed plane than a glider. RON
