RE: HOW-To..3D maneuvers
Inverted Flat Spin
Requires High rate rudder and elevator and aft CG.
1. From any attitude, push full down elevator, full right rudder and full left aileron.
2. As the plane starts to flatten out continue to hold full down and full right rudder, ease the ailerons back to center.
3. Adjust ailerons as needed to level the wings. Adjust the throttle to keep the nose level.
Variations
To make a nice transition, slowly ease off of the rudder and let it come back to center a little at a time, adjusting throttle and ailerons to control attitude and wings level. The spin will start to open up into a flat circle and the diameter will increase as you let off the rudder. The the spin rate should decrease to a slow lazy flat inverted turn and look like a lazt falling leaf. From here you can transition into an inverted harrier, rolling harrier etc...
