How do u do a upright blender
My Magic was capable of blenders in both directions. I normally go to an inverted left flat spin. Beware, as I've snapped the rudder twice in violent blenders, (no throttle, but picked up good speed on the vertical downline). No biggie, it will just flat spin to the ground, go pick it up, glue the rudder back on , and go fly somemore.
For some reason, my Magic will flat spin like a Frisbee upright but not inverted. Oh well. Its been sold and I've moved on to the next plane.
Just make sure your CG is aft enough. Hands off inverted should at least be level or better yet, slightly climbing. And of course, lots of control deflection.
Good Luck.
