I had some issues with my quad this evening.
I have an Eachine Wizard X220 that has only been out for a few flights but has experienced a few crashes as well. This evening when adjusting my rates, I wanted to test the arming as I enabled the idle motor spin when the quad is armed, so (yes, I know I did a bad thing and I learned my lesson the hard way) I put on the props and set it on the ground, powered it on and flicked the arming switch. It seemed fine so I gave it a little throttle and then backed off to 0. However, the quad didn't. I quickly disarmed the quad, but yet again, it didn't. Instead, it increased the throttle and even remained armed when I powered off the remote. In fact, it throttled so high that it lifted off and then spiraled and crashed, destroying all 4 props (two of them hit me but I'm alright).
With the threat of the props gone, I plugged it into my computer and opened betaflight. There didn't seem to be anything wrong with my config except for the fact that receiver tab did not show anything. (See pics: https://drive.google.com/open?id=0Bz7gw_c3GS-ETGswQnRseElDaG8) Nothing has changed since my last flight except for the fact that I adjusted my rates and the idling motor when armed. I even turned the idling off and still was experiencing receiver issues.
When I power on the quad by batter with the remote on, the remote connects to the quad no problem, but it wont arm. When the battery is in and connected to betaflight, it doesn't show that it's receiving any inputs.
I'm at a loss. I reset the quad, reset the remote, verified that all my wire connects were solid on the quad and that everything was the way I had it during my last successful flight. The receiver on the quad is receiving power but it just isn't sending signals to the board.
I would really appreciate any help anyone could provide.
