Connect this on the Dx6i spektrum. Two working modes are set during the power up:

• If the Throttle stick is at bottom, the timer is enabled by moving the stick and pause when stick return to bottom.
• If the Throttle stick is at middle, the timer is enabled/paused by the gear switch changes

In all case, Trainer switch can bypass the automatic timer start.
