Techproaviation from Czech designed and is producing parts for Merlin and Merlin Lite. Many airplanes which have very nice flying qualities are designed and parts built by Techproaviation and then sold by different companies as their own kits or Ready To Fly airplanes.

My suggestion is to use professinal blueprints of aerobatic airplanes. There is an airplane with a great flying characteristics and at the same time with a high level of durability - Zivko Edge 540.

I've found an option to outline blueprints here: Zivko Edge 540 Clipart - Download Aircraft Clipart Images and Blueprints in PNG, PSD
Or you can use free ones from this source: https://www.f3m.com/spain/3view/Imagenes/fai edge 540.jpg
And what does have to do with the single tube idea, please explain !

A quick update...

I shortened the fuselage a little to keep the gear from interfering with the pilots feet

Higher parts count than the AP but half the weight. Either tin snips and templates or CNC would be easy enough.

The wing would be tin, I just stuck the ranger wing on to see how things line up. I'm still not sure what motor it needs.

What kind of tubing would be required to build this one, and what size and gage of gussets would be required?
