Flight controller help
 

I’m looking to build a hex or a octacopter designed to lift a RC Skydiver (4lbs 12 oz) leaning towards a 960mm hex with 18” props
i have figured out the mechanical but can’t seem to find any current information on flight controllers other than DJI and I’m not a fan!
i have used eagle tree vector, and a NazaV2 in the past for discovery and discovery pro and several board types for small racers
I also have a couple of Yuneec camera quads as well
can anyone provide info for FC’s used in the larger format platforms?

Thanks
Terry
