How to set up CH8 HeliRSC with HereLink?

If you are not using the wheel channel for anything then use it for the motor interlock. The channel that is assigned to motor interlock can be changed. It doesn’t have to be RC8.

1.Thank you for your answer. I have changed CH8 to D button
2.What is the meaning of M/T in BUTTONS?

I don’t know. I am not familiar with the HereLink controller. What software program are the screen shots from? Is this QGC?

It’s the app for setting the remote control in HereLink
I have read the manual but I don’t understand what he said

Could it be momentary/toggle?

It should be thank you
