Re: Crazy robot idea for this year 2

You completely missed the point of my post which was that you don't need to balance weight with thrust to get a vehicle to fly. A Helicopter relies on the same principles as an aircraft however the wings move above the craft rather than the craft moving through the air to generate lift.

And spinning blades are any better? Let me tell you a story now that we're on the safety train--

One time, bout 5 years ago at the RC flying field I am a member of, there was a gentleman tuning a new helicopter he had just built. This was a 0.30 cubic inch engine size heli, nothing big, bout 5lbs weight, with a rotor diameter of about 3 feet. While checking the rotor balance, he lost radio communication and the throttle was stuck wide open. Luckly the collective was in the neutral position so it just sat there on the ground at full power. Well this guy decides that the best thing to do is to reach under the blade and pull the fuel line off the engine. While he was pulling on the line to get it off the radio cut back in and the machine twitched. The sound was sickening- his arm was clipped by the rotor and broke it in three places. We rushed him to the nearby hospital and the resulting damage was so bad it requied 68 stitches, multiple reconstructive surgeries and he nearly lost the arm. This was after they cut off the leather coat he was wearing to get to the wound.

I would far prefer seeing fixed wing aircraft than rotary wing aircraft.
