Hi everyone,
I bought a new Eachine Wizard X220S. I tried to do some tutorial to configure it by using Betaflight.
The signal from the Sky-I6x can be decoded by observing from Betaflight. After that, I connect the battery and try to make motors run but nothing happened.
However, I can make motors spin directly by using sliders in the Betaflight software (in Motors tab).
Please take a look at the following video and suggest me some solutions.
