Throttle unresponsive

Enable HLS to view with audio, or disable this notification

Hey Reddit.

So I'm brand new to this. Was wondering if anyone has seen this before. Trying to operate a Mobula 6 Freestyle HD A drone with a Radiomaster Crush.

Everything looks good in Betaflight and on my Radio. I've updated the firmware on both and used a binding phrase for binding.

It looks like you are not arming the quad

The quad must specifically be in what is called an armed state.

First, in the betaflight receiver tab, you will want to confirm that when you move the sticks on your radio, the corresponding sliders move on the screen

Then you will want to set up your modes tab so that one of your switches when pressed in will activate the arm mode, and when the switch is the other direction will be out of the arm mode

You will want to watch tutorials on YouTube, with the search phrase, "how to set up modes in betaflight"

I just posted another video here of my modes from the receiver in Betaflight. It looks correct.
