That's an unusual length for a #2, at 2-1/2 inches long, if I'm reading this correctly. Any chance of using blind nuts and switching to a machine thread?

I'll take a look downstairs, as I have a collection of hardware. Maybe someone here may have some to donate?

Agree, this thing looks like a commercial grade sewing needle. It holds the wing on an AirfieldRC 55" P-40 Warhawk. I went to finish putting this thing together over the weekend and only found one screw. Went to local hobby shop and it was a no-go. The AFRC website offered no contact info.

I'd probably just rework it a bit, to use a larger screw. I haven't bought any foamies in a while, but I remember the GWS setup with 3mm machine screws and nut inserts. I always reworked those setups a bit, tying in the mounting plates with CF and light ply. I would not be surprised if you could improve on the Airfield mounting plate setup a bit, if you reworked it.

Check with RTL, if they don't have it I'd be surprised.

Wow, I never heard of anything like that before. I gave a look it does not seem like even Fastenal carries them.

If they don't have it then I am at a loss for that size. Can you modify it to accept something else?

I have a Fastenal store within walking distance of where I work. May go have a look. Online stock could be different. Thanks!

You could get any length 2mm screw and just cut it down to length. Scew a nut on first if you have one to "clean" the threads when unscrewed.

McMaster-Carr is usually the master of oddball hardware. You might need to make do with all-thread and nuts...

Ask me why your DX5e is doomed... and how to fix it.

Last ditch solution, if you are staying with the #2 wood screw:

I've often extended pushrods with brass and aluminum tubing. The key is to crimp a number of nicks on the wire ends, which provides a good grip when the tubing sleeve is CA glued across the two parts. You could use any thin screw that you can find, and then use the tubing sleeve to attach a cut off portion of a #2 threaded screw to the bottom.

Thanks all. Still haven't found one and may heed some of these suggestions.
