Balloon Powered Helicopter Third Attempt - modicum of success


I had plenty of suggestions on how to improve my Balloon Powered Helicopter and combining Justwantahover's suggestions with Amir Alamir's suggestion we are finally moving in the right direction - UP - still not flying high, but a definite improvement compared to attempts 1 & 2.

david vernon williamson has a great design that really works. Here is his comment and link.
One of the simplest ways to improve it is use a sausage-shaped balloon (Tesco) it's got something to do with the balance as it spins round. also use aerofoil shaped wings & only three blades. full instructions at http://durealeyes.com/rotodyne.html

Generally my projects are for my grandchildren to enjoy. OK, I enjoy them too. If anybody else likes them, that is a bonus. I like to keep my work as simple and basic as possible so that it can be copied easily and improved by anybody who wants to try themselves. I recycle or repurpose items rather than buy new and when I do buy I like to keep it cheap.
