Model Reset:

 Use this function to clear all parameters of any single memory 

except model type

 back 

to factory defaults. Enter this screen, move the cursor over the memory to reset and press 

ENTER

Select “NO” to cancel or “YES” to proceed with the reset, and press 

ENTER

. The display will then 

return to the “MODEL RESET” screen.

Model Transfer:

  To  transfer  all  parameters  of  one  memory  in  this  transmitter  to  another  Tactic 

TTX850 transmitter, move the cursor to this line and press 

ENTER

. Press 

 or 

 to determine if 

the data transfer should be done by wireless means or through a cable (through the USB data port 
inside the battery compartment).

WING TYPE

This is for setting the type of tail and wing confi guration for the model. Depending on the mixes used and 

setup of the aircraft, it might be necessary to change the aileron, elevator, or rudder reversing settings to 
achieve the proper throw directions for the model.

TAIL SETTINGS

“Normal” is the factory default setting for the “TAIL” type. Move the cursor over “Normal”, press 

ENTER

 

then 

 or 

 to select from V-Tail, Delta (elevon), and 2 Elevator options. Press 

ENTER

 to confi rm the 

selection. The charts below can aid in determining the preferred tail and fl ap setting for the model.

Normal:

 One servo each is used for aileron(s), elevator(s), and rudder.

V-tail:

 Elevator and rudder channels are mixed. Two servos are used in the tail – one for each control 

surface, with connections as shown in the graphic below. V-tail mixing controls the airplane’s “pitch” 
and “yaw” axis at the same time. If the elevator and rudder functions appear reversed at the control 
surfaces, it may be necessary to swap the channel 2 and channel 4 servo plug positions in the Rx. The 
travel limits for each servo can be adjusted independently.

Delta wing (elevon):

 Elevator and aileron channels are mixed, useful for aircraft such as fl ying 

wings and other models not having a tail. Elevon mixing controls the airplane’s “pitch” and “roll” axis at 
the same time. One servo is used for each control surface. Travel limits for each servo can be adjusted 
separately. If the elevator and aileron functions appear reversed at the control surfaces, it may be 
necessary to swap the channel 1 and channel 2 servo plug positions at the Rx for the delta wing mix. 
If the delta wing option is selected, and the “FLAP” option below is set to 2AI1FL, the elevator channel 
will mix 100% to the aileron channel.

2-Elevators:

 Elevator channel 2 and channel 6 are mixed for aircraft which have two separate 

servos moving separate elevator surfaces. Both elevators move independently, and are independently 
adjustable for travel limits, etc.

FLAP SETTINGS

The “FLAP” setting allows for confi guration of the ailerons and/or fl aps of the airplane. Move the cursor over 

“1AI” to select from the following options:

1AI:

 Use this “1 aileron” setting for normal wing types having one aileron on each wing, where one 

servo controls the movements of both servos simultaneously.

1AI1FL:

 This “1 a 1 fl ap” setting is for wings having one servo that controls the ailerons on 

both wings, and another servo (or 2 servos on a Y-harness) that controls the fl aps on both wings (both 
servos moving in the same direction). Connect the aileron servo to Rx channel 1, and the fl ap servo 
to channel 5 (not available for delta).

2AI:

 This “2 ailerons” setting is for airplanes having one aileron servo for each wing. Connect one 

aileron servo to Rx channel 1, and the other to channel 6. This setting allows each aileron servo to 
function independently of the other.
