My 2 cents;
1. Those bats are cheap at Walmart because they are produced by the hundreds of thousands. I'm wondering how much they would cost at a low production run.
2. Why stop at the body, do the wings the same way. Just add yardstick, a little glue here, a little glue there...
3. Most people I talk to don't want to do combat not because of the plane, but because of the other expensive stuff that can get ruined in a mid-air. Engine, receiver, servos, etc... I can't tell you how many needle valves I've gone through.
How about finding a retired guy, get him hooked, and let him build them and buy them off of him. There is someone here that is building them for $40 all ready to add equipment to.
And no, I don't really have a point....
