I'll make some measurements once I get home.

Possible solution to the rear landing gear leg

This is a mockup. I strung an elastic band from the LG leg to the interior of the wing.

There are two sections of plastic straw on the elastic band which allows it to retract into the wing.

Robert,

Very clever idea! That should work fine. Can't wait to see her finished and in the air.

This should give you idea of the sizes. The jackscrew is 48mm long.
I would probably use a 3D printer to build custom legs around the jackscrew mechanism

Final Medial Landing Gear Struts

Mockups of the medial landing gear struts were initially fabricated out of drinking straws and hot glue. The design worked and now they are made of aluminum tube and JB Weld.

A Bit Closer on the Posterior Gear Leg

The most promising solution so far for a cosmetically acceptable, retracting posterior gear is two short aluminum gear legs strung on elastic cord.

The function isn't quite right yet. The posterior leg still hangs up about one retraction in 15. I need to figure out a way to guide the rear LG leg upward so that it never binds.

I also added bushings for the axles so that the wheels would fit properly and used a washer and a cotter pin as wheel retainers.

And then there were two

The second LG leg is complete.

Bart came over tonight and helped me work on the LG. He came over to show me some progress on a Bush Hawk he is building. I hope he makes a build log. It looks great.

Tightening the elastic thread a bit solved the intermittent retraction malfunctions.

Thanks Bart and Don,

By the way when I wrote "Bart" of course it was Marysville Dutch Bart formerly of Zeeland, not Dutch Bart currently of Oostovoorne. In my experience one can never have too many Dutch Barts although it can cause confusion.
