I purchased two of these stacks and have had many problems. The gyros on both needed extensive filtering to even get it off the ground without flip. Finally I got them right after way to much time adjusting in Betaflight. Sure I've had some great flights when it's working properly but so not worth it. Now I see the plug for the fc on the esc is loose after I lost power in mid flight. Garbage.

After 3 flights, Plugged in 5S to my 7" and the negative wire on the provided Capacitor blew like it was a fuse. Since then the FC's gyro got worse and worse till it crashed on takeoff. Replaced just the FC and it was great again. The FC and ESC are a great combo. The plugs for the GPS and LED are great. It does fly amazing in my 7" build. Hard to tell if I would use this stack in another build.
