Here are some tips for you guys that want to learn the fast rolling circles. (aka KIKI rolling circles)

Start from level flight.
Pull the nose up a little bit, and shove full right aileron in it.
If the nose drops, add more throttle
If the nose climbs, pull off a little throttle.

You can control the nose attitude with the throttle. Forget rudder and elevator...you dont need them.
You want to keep the nose pointed about 5-7 degrees up. You'll be all over the throttle bumping it as it goes around in the circle, but it will do a real nice super fast rolling circle all by itself.
