<DIV><FONT face=Arial>Push vertical, 2 of 4, rolling in to the wind to wind
correct. Keep a touch of the same rudder in after the 2 of 4 to keep
fuselage from weather vaning, but just enough crab, with full power, to
prevent wind drift. Stall, add a little throttle as it comes
around for a nice tight stall turn, remembering the throttle curve that is
programmed into code 18 for precise throttle resolution around idle to 1/4
throttle needed for complete control. As it comes around add a touch of
up elevator and some aileron to keep the wings perfectly parallell to the axis
of yaw. Hold a touch of rudder as it comes verically down to wind
correct the weather vaning (again on the down line). Ease out of the
rudder gently to prevent any tail wag on the way down. By now you know
the natural frequency of your fuselage and exacly how much rudder is needed to
dampen any oscillation after the stall turn. Get a mental picture on
where the snap should be on the vertical down line. Once at this
perfectly centered point on the vertical down line, punch in down elevator, in
.25 seconds later come in with the aileron and opposite rudder. At
exactly 320 degrees rotation begin to release the down elevator, then rudder
then aileron, thus insuring that the snap speed remains consistent
through the snap yet releasing the controls in this order for a precise
finish. Draw an equal line after the snap and then concentrate hard on
the radius to make sure that it is exactly the same as the radius going
up. Continue to concentrate hard on the wings level and level pitch
exit. Complete. The Snap Roll is just one element of the
overall maneuver where everything, including airspeed up, airspeed
down come in to presentation and final
score.</FONT></DIV></DIV></BLOCKQUOTE></BODY></HTML>
