Hi. I want to use JIYI K++ V2 Flight Controller on my 50 kg hexacopter. I research this autopilot but I can’t find any user comment. Can you comment this autopilot ? Can it provides safety flight ? Is its Hardware high quality ? Is its ground station software enough?

This is an RC car forum.

Looks like a controller for a large UAV. I would consult a UAV forum, or maybe try rcgroups.com. Helifreak.com may have some info, but generally geared more towards single-rotor helicopters, so not gonna be your best choice.

I would look for a forum that is geared more towards large commercial drones/camera rigs.
