OK, lets see. This is a sure fire way, for me, to get in a spin. It takes some altitude to do this so clime high.

Stall you plane facing straight up. As your plane rolls over facing the ground push your ail/elv stick to the left and full throttle. Then slowly push your rudder to the right (your left stick is up and right). Slowly pull back on your elevator (now your right stick is down and left). Then slowly push your right stick to the right giving opposite aileron (your right stick is now down and right).

Presto, inverted flat spin.

Sometimes it’s easier than others. Most of the time it flies right into it.

Good Luck!
