Appendix I (Control Throws)

These throws are specific to the role of predominantly gliding. If you choose to go fast (DSing) be
prepared to modify the suggestions substantially to support higher speeds. Similarly with slope
aerobatics. I generally stooge around at best glide slope looking for lift with the odd sprint through
sink (+2mm of camber).

Launch Mode

High rates set (rate selector switch inactive), camber preset at -3mm, elevator preset at +1.5mm to
initiate the climb out and 2mm right rudder is preset to counter prop wash rotation. Throttle set at
100% (full). Mode is selected on the right hand spring switch.

Best Glide Slope Mode

Normal mode is selected by the middle position of the top left switch. The rate selector switch
(top right 3 position switch) is active controlling aileron, elevator, and rudder as a set.

All measurements are in mm, + is up, - is down. Exponentials are shown as percentages.

Flaps

Mixing

Camber and flaps to elevator active, 0 to -9 at full deployment

Aileron Differential

active, aileron to rudder mixing 8mm to -8mm.

Loiter Mode

Medium rates selected, rate switch not active. Camber preset to -3mm, left slider camber control
from +5mm to -8mm. Aileron differential and aileron to rudder mixing active.

Landing Mode

High rates selected, rate switch not active.

Crow active a11, flaps -12 right slider controls flaps to -30.

Elevator mixing active -4 mm to -9 mm controlled by flaps.

Aileron differential off

Aileron to rudder mixing off

NB

Do not land with full flaps deployed. Once in ground effect switch to normal mode
