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!
