How is this for cheap?

I put one together it flew great 'til I dumb thumbed it showing off.
I made it a tail dragger and threw a TT GP 42 on it.
I covered mine with econocote. Yellow on top and black on the bottom. It was a sweet flying plane. I am working on it's twin right now. At $30 I could not resist and bought two more.
Next week or so I will cut some cores and make a 8' wingspan version. I am going to sheet the foam cores and put a Saito 180 on it.
The small one flew great. The bigger one should be perfect!
