Hi Christof

Looked at this thread after a long time. Excellent work!
Couple of questions
1) How do you machine the CF?
2) How do you ensure alignment between connectors on the central hub and those on the detachable arm
3) What safeguards do you use to ensure motors point vertically up?

Hi Srinath

1) How do you machine the CF?

I use a portal milling machine with a HF spindle and 2mm bits.

2) How do you ensure alignment between connectors on the central hub and those on the detachable arm

I placed fitting bores in the upper and lower central plate. The arms have (perpendicular to the prop plane)precision bores. At asssemly time I use bolts to ensure that all motors are aligned.

3) What safeguards do you use to ensure motors point vertically up?

It showed, that even the connectors align the arms very well once adjusted. I use the alignment holes at both ends.
In the attachemnt you can see the alignment holes in the center of the brackets.
Cheers
Christof

What a beauty Christof and smooooooth...
Looking forward to see it in real life.

[kinderkram]

Yeah! Bring that beauty to the MF.

[teramax]

yea Chris, flies and looks beautiful but the motors sound like breaking in pieces in the moment.
Is it just the video?

There is a little nervous sound when yawing hard in real life too. Maybe @ MF I get some tuning help to get rid of that. But otherwise the sound is fine for a 5Kg machine and 13" props.
