Hi,I have started a build of a 2.5m Octocopter.One of the many difficulties lies with the flight controller, as the ones I have seen are sometimes limited in size, presumably because of the PID algorithms.Does anybody know or have experience to recommend a flight controller suitable?Many thanks.

I want to know what's you power system?
Beware that the more big are the propellers the more difficult is to control their inertia.
Start with a smaller and most important with a lightest copter do some filming and then reconsider your project. t
You will probably find that flight time is essential when you do filming especially if you have a director without very clear ideas.
Anyway I will start with a traditional Pixhawk and not a Pixhawk 2.1 , if you buy a Pixhawk made in Usa it is more reliable than the 2.1 IMO
Thanks for the suggestion Armin Strobel, I will have a look.
I should have explained more perhaps, the platform is for filming, so I am looking for something very stable.
I am also quite interested to delve into the system, if it is open, but thats another thing.
Depends on the application you looking to use your vehicle for.
Without that knowledge i would advise anything where you can install the PX4 firmware stack. For a big machine I probably would use Pixhawk 2.1
It will take me some time to real about them in turn.
Here are some of flight controllers Dji N4 , A2, A3 , MikroKopter Flight Ctrl , TopXGunT1 , PX4, PIX-HAWK CUBE, PIX-HAWK
