About The Project:

The airplane is a home-built, scratch-built Zenith CH 750 STOL. Building from plans/blueprints is a challenging way to build an airplane, since most of the parts you use to build it are not prefabricated. I chose the Zenith CH 750 STOL for its rugged design, its STOL (Short Take-Off and Landing) characteristics and its aluminum construction. Zenith Aircraft Company has designed this airplane so that it can be built from scratch or from a kit by the average person. They provide excellent technical support for both kit and scratch builders. In addition, I'll be installing a 1965 Chevrolet Corvair 164 cid horizontally opposed, air cooled, 6-cylinder engine, with special conversion parts to make it suitable for airplane duty. This is what the airplane will look like when I'm done, although I'll have a different paint scheme:

Flaperon Skeletons

Friends,

Prior to starting the Horizontal Stabilizer build, I actually completed the Flaperon Skeletons. I riveted them together prior to skinning, which I'm not sure was a good idea. I'll still need to de-burr the rivet holes for the skins, but I think I can manage that with the skeletons assembled. I did not go that route with the horizontal stabilizer, though. Anyway, here are the skeletons primed and riveted. I need to fix one hinge bracket/nose rib combo due to an alignment error. It will require making a new bracket and nose rib, and match drilling them to the existing hole in the spar. If I mess that up, I'll have to build a whole new flaperon skeleton.

All 4 flaperon skeletons. 2 each make up each flap/aileron combo:
 

I didn't shoot much video or photos for these parts, though I do have some video footage of assembly. More on that later...

Cheers!

  1. Are the flange gaps in the flaperon ribs (the gaps that reach the flat of the rib) a modification from the original design?

  2. I'm assuming you're talking about the two relief notches on the top curve of the tip ribs, and the corresponding single relief notch on the nose ribs? If so, those are specified in the blueprints.
