Quoting Jeremy McCreary
A perfectly plausible pair of desert plunders.
Thanks! Another one you might be interested in - the only Steamy-build I've done so far that actually has something functional built in - is the Red Falcon. http://www.mocpages.com/moc.php/334257. It's chunky and awkward, and the gears tended to slip, but on a good day I could get it to sustain some pretty good flapping. Still wish I'd videoed the thing... ah well... maybe there will be a future re-build. Need to work out a simpler mechanism. Simplicity is hard.
