@tieffe 22xx is the right diameter, you want to use low KV motors for longer flight times.

The 4in1 I've got doesn't fit, is the naza body wider than the f3 body or the other way round and what's the size difference.
Is it just the body that's different between the versions?
I'm hoping I don't have to redraw it.

Edit, I can get the board to fit but not inline with the gyro so will either move the gyro or altering in the configurator. I need to move some mounting points around and print another one otherwise it should work.

I am working on a new bottom that will have better spacing for 4in1 and also slot for optical flow sensor.

Hi, where I can download stl files? I am logged in but download section does not displays!
