I have laser cut ribs for the Sterling Mustang and Yak 9 planes.  I believe these are cut the way the plane was originally done and not modernized.  Plans can be downloaded off of the Internet.  $15 for a set of ribs only.  I can bring to the NATS.  Otherwise shipping would probably be $5 to $10.

Are you going to cut any twister ribs. I’d be interested in a couple of Francher sets.
Thanks

These ribs were some I found in my dad's stuff.  I have no idea where he got them.  Or even how to cut some Twister ribs.  Although that is an interesting idea.

Any chance of showing some pictures of the ribs?

I am not sure how to compress the picture to fit.  If I can send it to someone full size and then they compress it for me and post it that would work.
