I've seen the Greg Po thing on TV and from what i remember of it he started off straight and level and went into a snap roll of some sort (can't remember if positive, negative combination of both etc). The point of this was, i guess, to build up a load of momentum, though exactly how he initaited the pin wheel part of it i don't know! Bet there were a few recycled dinners before mr. Po figured it out too!

John Willmam described something a bit different but with a similar result. A way to get the plane to swing round better is to kick the tail from side to side on the vert. up line. The plane should begin to build up a bit of momemtum with the nose yawing to and fro, further and further from the vertical. As speed drops off, you need to use the momentum, along with full rudder (provided you have enough) and full throttle to take it round, though as John said you may have to fight it a bit.

Mind you the "Po" pin wheel is much more spectacular. Most models are probably too small and light to build up enough momentum to do it, though the above mentioned vertical entry version is easy enough povided your plane is capable.

See ya
