.....do that thing were the plane pitches up and doeslots of 360* stall turns?

ive seen a full size pilot 'greg po' doing it. he called it the 'po pinwheel'

Unless I'm mistaken, I believe a pinwheel is a Stall Turn/Hammerhead type maneuver that goes past the normal 180 degrees. Your description of "plane pitches up" has me a bit confused. Do you mean a vertical up line, or a sudden pitch up? There is also a maneuver called a windmill that involves a plane pitching up (basically a tight inside loop) but it doesn't involve a stall turn.

As for the pinwheel... I suppose you can enter this from anytime you are pointed up, i.e. torque roll, vertical line, etc. To start, fly good clean vertical line. You need to be sure it is really veritcal. Slow down like you are getting ready to do a stall turn. Then do the stall turn but don't release rudder across the top. Instead hold full ruder and add power to do the 360 stall turn. Engine torque and outside wing generating more lift than inside wing will cause all sorts of funnies. You may have to play aileron and elevator to keep the plane vertical during the pinwheel. Sometimes it also helps to kick a little opposite rudder just before the pinwheel so that you have a bit more yaw momentum before the maneuver. I suppose one could just thrust vector the whole thing but this maneuver seems easier on larger planes where inertia is in your favor.

Not a lot of RC planes will do this - my UCD was the only plane I've owned that could do it. You'll definitely need lots of rudder throw and a strong rudder servo to do it.

thanks flyfalcans and JohnWillman. comming to think of it greg po (in a edge 540 full size) as flying in a strait line the he wiggled his tale left to right then it kinda did a pinwheel but ging forward

Howabout that TOC guy (can't remember the name) that mounted a model rocket motor on his tail that kicked it around?

only brought my Bug coz there were doing this at Woodsprings, mine wont, POS

...

how do it..... learn to write in English !?

Ian, please tell me it is keyboard skills... you cant honestly get away with it at school !

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
