Henderson-Glenny Gadfly, scratchbuilt 1/72

The smallish Gadfly I started life in 1929 as an ABC Scorpion-powered conventional monoplane of simple lines and conservative design. Soon after, though, its ailerons were deleted and instead a new device was installed, the so-called "oyster" rotary ailerons, becoming the Gadfly II. Gadfly III had a Salmson AD9 radial.

This rather simple and small Gadfly is representative of an entry-level project, but there are plenty of other good candidates out there.

I happened to have an old Aeroclub Salmson 9AD white metal engine (Aeroclub accessory), so I will be building the Gadfly III (G-AARK) that had that engine. Photos can be found of it flying with either "oyster" or normal ailerons, but I will do the "oyster" ones, since have never seen them on a model.

The techniques and resources used for the build are far from being written in stone, and there are many ways to solve scratchbuilding engineering challenges. The build is meant to be only indicative of some basic approaches to the task, for those interested in scratchbuilding endeavors. Decals as usual from Arctic Decals.
