I'm new to the hobby and I notice that the feed from the FPV camera has a lot of static that are very distracting.   Is there a method of eliminating or minimising them?

I also notice that most quad FPVs frames are using light weight carbon fibre flat boards cut to shape but has very little consideration for high stability fast flight aero dynamics.  Is anyone besides KAREAREA thinking laterally?

Hi D9D, welcome to the forum.
The noise in your FPV feed mostly comes from your motors/ESC. If you have a noise setup, try adding low ESR capacitors to your ESC power, or at the XT60 lead:

Ahhh yes... caps do help them oscillating voltages smooth out.
