Plan to sand a heck of a lot, Tapio. Most will be from 40% out to the tip.

My impression is that:
6K is larger than the specified 15x15 thou. More like 20-25 x 15 thou.
3K for me seemed to be not be enough until slightly past the 13x13 thou section. Hence the 40-45% doubling.

My test props I barely sanded so they are overweight. Although with 1.4 grams available, not really. They can readily scrub the ceiling and almost never tuck. (I think one tuck in the last 4-5 flying sessions with a lot of pole steering being done. That one was an odd bump that hit just right.)

Good luck with it.

Regards.
