Extremely cheap homebuilt helicopter . . .

Well, the rotorhead at least. If anyone makes a complete working model, I'll be impressed.

Nr,

That is a sad, sad site! Helicopters are complicated enough when they fly but to do it just for a Lego toy that will never fly - well! :rolleyes:

Someone has too much spare time on their hands. I would rather watch a full episode of Eastenders or dig my garden for a full day and I have never done either yet! ;)

I wonder if it could be a useful teaching aid. Especially for those students who fall asleep or look panicky in briefings if the words, pitch, rotor disc, or torque are mentioned! :eek: :confused:
