This is a standard HL M35 and the crate in the back holds all the gear for FPV, as well as the gear for the light bar, with plenty of room left over. I'm using a 3S lipo with a step down to provide 5 volts to the light bar. The fpv just runs on straight battery voltage.



And here's what's in the crate



I'm thinking about making a smaller crate. This one was originally planned to hold two different batteries, one for lights and one for fpv, but a tiny little stepdown board meant I could eliminate one of the batteries (thanx again, Erik).
