Rudder setting: adjust the rudder travel to roughly
45 degrees in the left and right directions with
the ATV function.
7. Dual Rate setting (D/R, p. 26)
Adjust the servo motions with the D/R function
(in the Basic menu).
Aileron Dual Rates: adjust the aileron travel to
roughly 7/16” (11 mm). You may also wish
to adjust EXP so that its rate is -20 to -30% to
soften things around neutral.
Elevator D/R: adjust the up side to 15/32” (12
mm) and the down side to 17/32” (13 mm).
EXP should be -15 to -20%.
Rudder: adjust the left and right travel to 40 to 45
degrees. EXP should be about -20%.
8. Airbrake (ABRAKE, Advance menu, p. 47):
an airbrake effect is obtained by raising both
ailerons and adding elevator to trim. This high-
drag configuration assists landings in small
airfields. It is possible to loose some aileron
effectiveness so test the airbrake effect at altitude
before trying it on a landing approach. You
should spend some time fine adjusting the elevator
travel so that there is no trim change with the
application of airbrakes.
The rates may vary considerably for different
models, but for initial settings choose the flap rate
to be (+)50-55% for both CH1 and CH6. The
ELE rate should be set to -7% - -10%.
We recommend that you select the Manual mode.
The default airbrake switch is SW(C), lower
position ON. Move SW(C) to the lower position
and verify its operation.
9. Snap Roll (SNP, p. 50, Advance Menu)
Activate the Snap Roll function by pressing the
plus (+)
key.
Set the deflection rate for each switch position.
Be sure that the direction of motion of each
control is correct.
Aileron: 80 - 100%
Elevator: 90 - 110%
Rudder: 60 - 70%
We recommend that you activate the safety switch.
This stops your model from snap rolling if the
landing gear are not retracted, so you don’t
accidentally snap while taking off or landing.
If your aircraft snaps poorly, increase the
deflection of the elevator and rudder. Note that
some models don’t snap even when the control
deflections are increased. This may caused by
too far forward center of gravity, or by the
characteristics of the airplane.
10. Failsafe settings: we recommend that you set
the Fail Safe function (F/S, p. 29) to move the
throttle to idle if interference is experienced.
Note that the failsafe function only operates in the
PCM transmission mode.
11. Now take advantage of your system’s other
great programming capabilities. You may set
such functions as Throttle
→
Needle and Throttle
delay to improve engine response, and couple
elevator to flaps for tighter corners in the elevator-
to-flap mixer (ELE
→
FL, p. 48). You may want
to use programmable mixers to get rid of
unwanted tendencies (for example, pitching up
during knife-edge flight. Finally, if you have
dual elevator servos, you can turn on the Ailevator
function (ALVATR, p. 49) to increase roll
authority in low-speed maneuvers. The sky’s the
limit — enjoy!
