Hi! I posted this moc a while ago in a specific topic as an example, but I never made an own moc topic for it. JFAIR "contest" has "no rules", and the theme is about really flying Lego things, or things related to fly, so I think it's a good opportunity to present this moc: http://www.brickshel...ry.cgi?f=500935 The machine has a very small frame (7L beam), and two propellers for propulsion: http://www.brickshel...y.cgi?i=5432844 Here you can see it flying and raising: (I don't know it's the first, or not, it just flies. ) I think a flying Lego machine can raise from it's own power. It's easy to throw or spin something with your hand. I made some experiments with pull back motors, because they are pretty powerful compared to their size and have lot of rpm, which is very needed to generate raising force. So it can raise/flying off only with Lego parts. The motors with the base structure, the flying thing are all 100% Lego. Yes, it can't raise too high (0,5 m max.), but the flying itself was my goal. Flying time is about 1 sec. The accelerating unit contains two pull-back motors: http://www.brickshel...y.cgi?i=5432841 (I used these motors, because with (even with overvolted) Lego electric motors it seems, it's impossible to fly without wires between the ground and flying machine. And, If I use wires, then it's not a flying machine, because it's connected to the ground.) The video was recorded with 600 FPS. We made some 1200 fps videos, but they have pretty low resolution.
