Here are some links to YouTube videos that explain a little bit about the Flea and show the details of its construction

Building the Flying Flea: The Project (introduction)

Building the Flying Flea: Wing Ribs

Building the Flying Flea: Wing Spars

The Flying Flea was designed in the 1920's by Frenchman, Henry Mignet. After some early design issues the tandem wing design has proved safe and easy to fly. There have been lots of variants in the evolution of the concept. The HM293 is the version that I have chosen as my next project, like the one above. It is very simple to build with no ailerons. And, quick folding wings make for compact storage.

I made a wood kit for the airplane and took it to Florida to have something to work on as we spent the winters there. But, I've been so busy with other activities that I have not started the wood construction.

The wood, Sitka Spruce and some lumber store softwood, all milled to the correct dimensions.

Thia is the wing rib jig that has the 4 different size ribs layed out, 2 on each side.


 4/25/2020 - However, back in Pennsylvania we are stuck home due to the COVID19 virus so I have started working on the metal parts.

The control stick assembly cut, welded, and powder coated.

Assembled and ready to go.

I have started making wing ribs. About 36 of the 51 needed have been completed. Production was interrupted for a little while as I worked on an Avid model C.

I totalled up the parts that went into making the 51 ribs and this is what it took: 871 pieces of 1/4" square wood, 1996 1/16" plywood gussets, and 5812 staples plus about 1/2 quart of T-88 epoxy.
