Sounds reasonable to me. The Shockflyers go for around 65 bucks here.

I just finished building a mini ultimate biplane. 22" wingspan. Flys on a GWS S1 motor with a 7.4v 350mah LiPo. Enough power to fly, but could probably use a little more for 3D.

22" sounds like a lot, but on a biplane, the plane is really small.

OH YEAH heres a HOT TIP!!!!!!!

We all like to use carbon fiber for stregthing up the fuselage of the foamy planes. Only problem is a carbon fiber tube in the hobby store runs close to $30 bucks......but heres the tip!!

Goto wal-mart and look in the sporting goods section. You will find carbon fiber arrows that you shoot with a bow. They are SUPER light, and VERY strong. Just cut the ends off with a dremel tool, and yank the fins off. Use CA to shore up the ends....

Here's the Kicker....Total cost $4.69
