What is gt-jtx? I feel it's cool to control an airplane with a 3d joystick rather than gimbals. It's intuitive and real aircraft pilots (or those trained on MSFS) can appreciate. See Yoke and HOTAS ("Hotass")

After a good amount of self provocation, I embarked on the journey of doing a joystick based 4 analog and 1 digital channels transmitter for controlling Airplanes. Additionally, this system needs to have a basic menu system, settings (Expo/Dr, Rev etc..) and a monitor

The gt-jtx uses a 3d joystick for controlling an RC airplane. The X axis map to ailerons (roll), Y to Elevator (pitch) and the joystick grip twist/Z axis map to Rudder (Yaw) control. The throttle control has a separate pot on the base of the joystick. Digital push buttons 5-12 on the joystick base are trim switches for the four channels and pressing unique combos on these switches along with power switch navigates through the menu and settings screen.

There are three variants of the gt-jtx in order of ease of development

• Arduino Mega - V1.2 available - Open TX
• ATMEGA 8 - V1.0 available - Custom firmware
• ATMEGA 32 - Work under progress

See the wiki for more details
