29" Kobra parkflyer

This Kobra was designed 1980 by Lars Holmgren to be a parkflyer by 1980's means. Hand launched, no landing gear and a Cox baby bee or tee dee glow engine.

Chris F and I was discussing building a portable fast aerobatic glider when I got a hunch and started rummaging around in the garage attic and found my old Kobra which I built when I was around 12 years old. It newer flew, a lot of things came between and it got forgotten until now. I had an idea of making it portable but I broke it in the process, probably for the good as it was built wrong. I managed to get hold of some .PDF plans (thanks Sebbe ). Got another hunch and started rummaging around in the barn and found the original plans with the magazine it was presented in. AUW at that time was +500g. It's a fast flyer that can do everything a aileron/elevator plane can do.

It was drawn to be fast and cheap to build, all you need is 2 1.5x100x1000mm, 2 3x100x1000mm balsa sheet. and 1 10x10x1000mm balsa rod.

The idea is to make it portable which means detachable wings and detachable horizontal stabiliser. The fuse will get a fixed 4mm CF rod and the wings 6/4 mm CF tube and main spar made of 3mm plywood instead of balsa.

Den är kul & snabb ;)

Jag stoppade i vad jag hade hemma, en TP 2408-21 på 2S och en GWS 8x6HD.

Är halvnöjd med ett servo till skeven, ska stoppa i 2 5gr i vingarna i stället.
