I also found this to try out

Nice! Best idea I've seen yet, and adheres well to the KISS principle.

Yeah, thats a good way to start.

I will try this one, a 3mm centered reference hole perpendicular to arms and centerplate. Adding a precision bolt at the time of assembly should give good results too.

Thats also a good alternative but the holes need to be in the exact position. Preferably with a cheap solution.

On mine with round booms, I place the copter upside down on a flat surface (my bench) so it was resting on the ends of the motor shafts. Then I ran a small machinist square all around the edge of the motor rotors and adjusted till they were perpendicular to the bench.
This assumes the shafts are of identical length

my approach to leveling. Four 3d printed cups lying on the motorplates and a flat surface. For a X8 config were the pros are pretty far away so prop tips are not close enough to compare, had to think of something like this.

I like the cups idea, but does it work to ensure motors are parallel on a coax? Probably just the angle of the photo, but in that last picture the motor mount plates don't look parallel to each other. In the past I've used a caliper to measure the distance between the plates at each corner... very tedious but a decent way to check.

Hi Max it is both, the angle the photo was taken and i only loosened one side of the clamps to quickly adjust the mount to the cup, for the sake of taking a picture and showing it ! The curcial parts after having them aligned is tightening the scewrs of the mount and clamps.

Thanks
