I also found this to try out

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

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.

Great idea, would like to know how you will get both holes exactly the same, some sort of jig?

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 :)

When the frame and motor mount permits that's how I prefer to do it. I first spin each prop on the shaft to make sure it rotates in the same plane, then level them to the flat surface.

None of this will precludes you from looking at the logs and adjusting the motors so the AQ has no yaw output or as Bill suggests turning yaw off and flying it and setting them for no rotation after liftoff. I've done dozens of frames and they all needed to be tweaked a little.

Before the AQ board I put them on a test rig that would show yaw rotation and balanced power from each engine at full throttle. Neutral stability is very important.

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
