left. When using the rudder in conjunction with the ailerons, the airplane’s nose can 
point into a turn (instead of pointing up and “skidding” through the turn), allowing the 
airplane to perform tighter, more coordinated turns.

RETRACTABLE LANDING GEAR (CH5)

Channel 5 offers non-proportional control of a servo, and is typically used to control 
retractable landing gear. Servo movement is limited to rotating the servo’s output 
arm to the end of clockwise movement, and the end of counter-clockwise movement. 
The switch for channel 5 is located on the top-left of the transmitter.

FLAPS (CH6)

Channel 6 offers proportional control of a servo anywhere throughout the rotational 
range of the servo’s output arm. This control is normally used to adjust the position 
of an airplane’s fl aps. The dial for channel 6 is located above the left stick. 

TRIMS

A “trim” lever is included for each of the main controls, located adjacent to the 
respective stick. 

The aileron, elevator, and rudder trim levers are digital in function, and always rest 
at center position. Briefl y defl ecting the lever to either direction away from center 
will cause the respective servo output to fi nely rotate to one direction, and will be 
accompanied by an audible tone. Pressing and holding the trim lever will cause 
the servo output to move repeatedly. During a fl ight, when the main sticks are 
released and spring back to center position, the aircraft should ideally not veer in 
any direction. If the aircraft does veer in a particular direction, click the respective 
trim lever until the aircraft maintains a straight attitude on its own. 

The throttle trim lever is analog in function, and can move mechanically up or down 
and rest at any point in the range. Moving the throttle trim lever slightly up or down 
will fi nely adjust the engine or motor at low speeds. For safety reasons, it’s a good 
idea to use throttle trim when controlling the engine/motor at very low speed while 
on the ground. For aircraft with glow engines, the precise position of the trim lever is 
helpful when determining the engine’s preferred idle point. The throttle trim lever is 
not active when the main throttle stick is above the center point.

REVERSING SWITCHES

Four reversing switches are built into the Tx, one for each main channel. Each switch 
can reverse the rotational direction of the servo that is connected to the respective 
channel. This is often a much easier method for changing the direction of a servo’s 
movement as opposed to altering the mechanical connections between the model’s 
surface and the servo. Refer to the model’s instructions for specifi c details.

DUAL RATE SWITCH

The travel distance of the servos for the aileron, elevator, and rudder channels can 
be changed at anytime by using the switch marked AIL ELE RUD D/R, located 
above the right stick. This switch will change the travel distance of all three channels
