Dennis, I didn't actually perform the manuever myself, but my IMAC buddy did it with my plane. So, I'm not sure the first part is a pop-up or maybe called something else.

As I recall, he stalls the plane so it flips doing nose-down, at idle. With the plane travelling vertically downward, he pulls up elevator to "pop-up" the nose of the plane. With the plane temporarily popped up, he gives a little throttle to keep the nose up at 45 degrees or so to maintain a Harrier. Then the plane can be "driven around" in the harrier position while carefully balancing throttle, rudder, elevator and aileron to keep it from falling out.

When initially popped up with full elevator, the plane would quickly snap out when the nose came up, so it could never transition into a harrier. By adding the spoileron mix with up elevator, and adding 1oz of tailweight it got really good at the manuever. BTW, this is one of the manuevers he has found that smaller aerobats usually have a tough time doing. His 40% Carden Edge has no problem.

He could do the full 2002 IMAC Intermediate routine with my plane. Also, not typical for a small aerobat, with extremely axial rolls.

Yes, the spoileron mix is definitely on a switch.
