RF Interference
#1
Any idea what may fix this?



Note, this is RF interference, not electrical. There is a power filter in place. All of the grounds are good.

It sure looks electrical, given the picture is clear until you fire up the motors. When you say you have a power filter connected do you have your fpv cam and VTX running through it?

That's correct. It's possible that my VTX is damaged. I have a new one on the way.

Good idea, always pays to have a spare on hand, even if it is just for testing purposes.

I'd check if frame isn't grounded somewhere because You probably have antenna connectors touching it somewhere - hard to avoid that. Or solder a capacitor just for a quick check before a spare arrives.

The frame is grounded. It's an LS210. There's a hole in the top plate specifically for attaching an antenna.

What I meant - check if other ground wires/pads aren't touching carbon somewhere, You may have some ground loop that's conducting small current.
