The J-1B was one of those home built planes growing up that seemed to be very realistic to build. I’ve always been a fan of this plane, I think more RC models exist of this plane then the real thing.
The design was from the early 70’s & Poland
The simple but classic lines of this airplane still look good to me today.

In the mid 90’s I got a Plan for a RC 52″ span electric version from RCM, they went belly up years ago, Fortunately the Outerzone project in England has gathered RC plans that are no longer available where you can get a free pdf & building info.

The Double Ender bush plane looks like something I would have doodled up in a sketch book as a teenager.
Alec Wild brought this vision of a ground breaking aircraft into reality.

Quite the interesting web site for all kinds of unusual aircraft
You can click and drag on a PC or move your phone around to look around in the video.

If your needing some rapid prototype part for your project one company to check out is Proto Labs.
I saw adds for their company a few years ago for getting a design cube for free. it comes flat and when assembled its around 2″ on each side. It has molded in all the good / bad features to include with their processing. So if you want to use the company and these methods it can help guide your design before its finalized.
