CHANNEL 7
Full proportional control is possible, with a rotary dial. This can be used to control any accessory item where
smooth or precise movements is desired.
DIGITAL TRIMS
One trim lever is included for each of the four main controls, located adjacent to the respective stick. All
trims are digital in function, and always rest at mechanical center position. Briefl y depressing the lever to
either side away from center will cause the respective servo output to fi nely rotate to one direction. Pressing
and holding the trim lever will cause the servo output to move repeatedly. Ideally during a fl ight, when the
main sticks are released and spring back to center position the aircraft should not veer in any direction. If
the aircraft veers in a particular direction, click the respective trim lever until the aircraft maintains a straight
attitude on its own.
For models with glow engines, the position of the throttle trim lever is helpful for determining the engine’s
preferred idle point. The throttle trim lever is not active when the main throttle stick is above 50% full throttle.
REVERSING SWITCHES
Inside the battery compartment is a bank of switches, with one reversing switch for each channel. Each
switch can reverse the rotational direction of the servo that is connected to that 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.
The switch bank is numbered 1-8 each respective channel. Moving the small switch lever under the respective
channel number will change the direction of control for that channel.
DUAL RATE SWITCH
The travel distance of 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 simultaneously (not separately). With the switch in one position, each channel’s servo
will be capable of rotating through its full travel range (100%). Moving the switch to the opposite position
will limit the rotational range of each channel’s servo to 60% of its maximum rotational range. Placing the
dual-rate switch in one position can allow for better control of the model while on the ground, at low altitudes,
or while performing certain maneuvers. Moving the switch to the opposite position can allow for optimum
control of the aircraft in mid-fl ight.
The TTX810 Tx includes both wired and wireless trainer functions.
IMPORTANT!
Before fl ying the model in training situations it’s important to make sure all channel
reverse settings and trim adjustments on the teacher and student transmitters match! Otherwise, the
model could suddenly veer in an unwanted manner when the teacher’s trainer switch is activated.
Proper matching of the student and teacher’s Tx settings should ensure that no unexpected movements
occur when the trainer switch is pressed. This is especially true of the throttle control!
WIRED TRAINER
This option allows for connection to another Tx having a trainer jack, and can function as either the teacher
or student’s Tx. This also allows for connection of the TTX810 to some computer based fl ight simulators. See
the SERVOS AND ACCESSORIES section on page 12 for recommended trainer cords. Refer to instructions
