Uh, I'm not thinking "nightmare," just impossibilities. You would have to fly in dead calm. The variables of wind on the planes' surfaces would be impossible. Each plane would have to be the same weight, to a tenth of an ounce, powered by the same engine, tuned at the same rpm, top and bottom, with identical throttle throws and trim, same, balanced prop. And I'd like a section, 360 acres of flying field, to take off and land in.

And there are the variables of receivers and servos. Wow.

I think it's POSSIBLE, but you'd have to be willing to give up one plane in your mind, I'm thinking. You have maybe one chance in a 1000 of getting them both back on the field safely. But I could be wrong. I've been wrong before--and always learn from it.

I'm enjoying just THINKING about the challenge. Thanks.
