Another build that started with a frame. It was meant to be completely different as this frame allows for dual 16mm stack. But it ended up as inverted motors build. This frame is just incredibly versatile. As it turns out to be too powerful for indoors I may put Caddx Turtle or RunCam Split on it and convert it into micro HD setup that's safe to use around people.
It flies ok, but needs some troubleshooting:

Black lines start to appear on video feed to the extent that after several seconds of flight I can't see anything.
Motors get hot. I checked for motor screws touching the windings as some youtube videos suggested but screws are ok. Maybe I should make some adjustments to the tune.
If you have any suggestions as to what might be causing these issues, please let me know in the comments. Thanks:)

Might not be enough air flow into your motor windings becasue of the inverted motors. Just a thought.

Also, I would try to separate the vtx and rx antennas. No, it's not what causing the black lines but it will not hurt
