TTX850 Radio Mode Changes
The TTX850 can be set to any stick mode from 1, 2, 3, or 4. These instructions
describe how to change the stick mode on the Tactic brand TTX850 transmitter
between mode 2 and mode 1. Changing modes requires mechanical adjustments
inside the transmitter and electronic confi guration changes. Failure to follow
these instructions properly can result in permanent damage to the Tx and void
the warranty. Contact Hobby Services if you do not feel comfortable making
such adjustments without damaging the radio.
For safe operation and best results, it’s strongly recommended
to read these instructions completely before use.
Most radios for use in the United States are produced with stick mode 2
confi guration. The diagram here shows the difference between modes 2 and 1.
The locations of the aileron and rudder controls are the same for radios
on mode 2 and mode 1. However, the locations of the throttle and elevator
controls will alternate when changing between mode 2 and mode 1. Throttle
is on the left stick for mode 2, but on the right for mode 1.
Follow these steps to change the radio’s electronic confi guration from mode 2 to mode 1:
1. With charged batteries inside the Tx, start with the Tx power switch in the
OFF position.
2. Press the ENTER button on the bottom right and HOLD in this position.
3. Turn the Tx power switch to the ON position. Once the System Setup menu
shows, the ENTER button can be released.
4. Press the
– button to move the cursor next to the STICK MODE selection.
5. Press ENTER then the
– button to change the selection to “MODE1”.
Press ENTER again.
6. Press ESC to exit the System Setup menu.
7. With the transmitter linked to a Tactic receiver and servos connected to channels 2 (elevator) and 3 (throttle), make sure
both the stick and trim controls were swapped for the throttle and elevator controls.
8. If the controls for the throttle and elevator channels did not alternate, repeat steps 1-6 above.
