I have purchased a Xaircraft V8 with 8 coaxial octocopter. The thing is the electronics on this things are horrid.
So I replaced the entire thing with arducopter APM 1, new ESC compatible with arducopter as well as the motors.
When trying to set this thing up I noticed that there is no settings in the flight planner for Coaxial octocopter so I am wondering is there a step by step guide into how to get this setting on board the APM.
I have searched different topics but none of them gave a distinct answer but I saw plenty of people on here flying Coaxial 8 Octocopters using Arducopter
