The sequence for a blender is:
1) Vertical downline aileron roll
2) Snap
3) Slide aileron toward oppisite side to flatspin
Upright to the left would look like:
Vertical down at idle full left aileron
Throw in full left rudder and up elevator (for the upright snap)
Quickly slide aileron to the right enough to flatten
My Magic does it great. Upright flatspins are better than inverted on my Magic too.
Does anyone Flatspin their Magic all the way to the ground? The upright flatspins are like a frisbee and I'm tempted but haven't done it yet
