Dragonflyer is an ornithopter with 2 pairs of wings. It is a bit tricky on takeoff and landing, but it works. How to operate: AG1 activates the front pair of wings, AG2 the back pair. When activating AG1 only at first and folding the front wings a bit more the half way up, it behaves much like a “real” dragonfly when in the air. Throttle to let the wings flap with the desired speed, TRIM for trim. All other controls are standard, including landing gear. Takeoff: Keep trim in the middle and accelerate to abt. 120 km/h then put trim half way up. When in the air, retract the legs with landing gear and put trim back in the middle ore a little above. Landing: Reduce throttle to abt. 60 %, extract landing gear and put trim half way up. Gliding can be done with trim fully up. Have Fun!
