sliding side levers
Slide levers are located on each side, accessible from the back, for precise control of features such as flaps or FPV camera gimbals.
Proportional dial
The dial above the right gimbal rotates approximately 300°, for fully proportional control. Like all the switches and dials on the TTX660, it can control any and every function you’d like to assign. This ability gives the TTX660 exceptional versatility over the standard 6-channel radio.
