<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></blockquote>
