Let me see if I have the sequence straight:

1) Pull up 45 deg pitch
2) Roll 90 deg to the right
3) Throttle down
4) When the plane just about stops, feel both sticks to the upper right corner? Or is it upper left corner?

It really depends on your particular airplane & you will have to experiment with C-of-G, entry angles & entry speeds to see what works for your particular machine. I get better results from a vertical (or nearly) entry, or a steep inverted entry. For a "classical" Lomcevak, I stick everything into the upper left corners. For a "conical" Lomcevak the sticks are stuffed into the opposite top corners (left rudder, full throttle, nose down, right aileron).

Ah, I remember how I did it now.

Level flight, full power. quick pull to ~45* upline, then quickly full left rudder, full down elevator, full left aileron, and hold on. Part of the trick for me was the quick up elevator followed by down elevator, I think.

The fun is trying different things though. Good luck.

For some reason, if I go upper left corner both sticks, my Kangke Cap 120 goes into a flat spin briefly. This plane does best with both sticks at upper right corner.
