Hi, I am in search of making low cost and budget flight control boards using Arduino. I welcome comments from every corner on this matter.
Thanks
Have a good day

 

What you mean by flight controller ? What do you really want to build ?
Arduino ? Mumble ...

 

I am willing to make a 4 rotor dron (quad copter)

 

Rather than re-invent the wheel, you might find what you're looking for on one of the drone forums.
