I didn't count them all. There are eight of the 125 thickness required for the anti-torque tube. One of the drawings (FU125) from the web had forty so I assumed forty were required. I'll have to admit I haven't looked seriously at the frame yet. I was thinking if I'm having parts cut I might as well get the full sheet done. There is a $150 minimum charge.

I have 28 tabs holding on my formers. This includes the ones at the front inside the curved channel.

I used .050 for the former tabs, and used DuBro 8-32 blind nuts in the formers.

I have one of the first fuselages welded up by Jeff at Makelan. He used .06" for these tabs.
