I made mine from probably the same stuff.

I flew mine today. I just have to add some down thrust and make it less sensative. It is a fun fly type airplane that I specially engineered for me.

If that plane balances well on the spar and has a good amount of thrust deflection if will fly.

My friend has horible looking aircraft that were crashed repeatedly. He used a twig for the leading edge of one and he said it flew great. It also had a new front end that was looked like a box. The point is that if you saw some of them you would have no doubt that your plane will fly.
