There are no special binding instructions. The model powers up in Autobind mode and expects the bind sequence from the transmitter within the first 4-5 seconds.
When the switch is in the rear position the rates will be standard, when the switch is forward rates will be high. There is no need to move the throttle stick to the full up and full down position as with the standard controller.
One of the most annoying functions on the Syma X5C is that the motors stop when the throttle is pulled back. This can be fixed by implmenting Idle-up on the transmitter (think of this as a very simple version of the Betaflight "Air Mode"). Idle up will ensure that even when the throttle is all the way down, a minimum command is passed to the motor to keep them spinning and to activate the stabilization.
1. In the mixer menu add a line under Throttle and mix in a value of between 4 and 6 to be added to the throttle value if the switch is activated. What this does is effectively prevents the throttle from going down to less than this value.
1. When you want to fly in "idle-up" mode flick the switch and your stabilization will always be active.
1. Remeber to switch off idle-up as soon as the quad lands (or crashes - to avoid damage to the motors)
