The muscle powered planes can be really lite. What is the world lightest "real" combustion engine based ac ? Is it Whing Ding II ? http://www.planeandpilotmag.com/aircraft/international-aircraft-directory/homebuiltkitbuilt-aircraft/hovey-whing-ding-ii.html ...or is it Pterodactyl Ascender of 56,7 kilos ? http://en.wikipedia.org/wiki/Pterodactyl_Ascender Neither has closed cockpit and top speed is limited to 55 mph region. I am currently wondering if a 50 kilo plane with 100 mph top speed was possible. In fact I have 3-views of such ( of my own design ), but not made model of it yet. ---------- Reason why there are no more 120-150 lbs planes is possibly the fact that US FAA allows heavier planes to operate without pilot lisence; http://www.usua.org/Rules/faa103.htm

They are lite...but are they air craft ( AC ) ? How lite could a plane with protection for the pilot from rain and birds be ?

Well the Cri-cri came in at about 78kg and that's a twin that can fly on one engine. Colomban has also designed the Luciole that's not a whole lot heavier and a practical single seater.

Well paramotors (and paragliders) are technically classed by the CAA as aeroplanes. But although I fly them myself it is hard to think of them as 'aeroplanes'. I carry mine in a big bag that probably weighs less than the avionics in a PA28. I prefer to think of them as aircraft in the same way a basic microlight is one. To me an aeroplane has a door and instruments, and ailerons and an elevator or stabilator. If it don't have those kittens it isn't an aeroplane to me. I learned to fly in the 1970s on Cessnas and Pipers and all these microlite and ultralight aircraft don't 'feel' like real aeroplanes either. But some of them rock!

I agree VeeOne ! I have flown an aeroplane model succesfully with monowheel/ski without the rudder control..but tricycle landing gear would need a rudder steering too. I'll save few kilos when leaving the pedals away on my monowheel design. I think also that ac would need to have a feeling that you are protected from the hard slipstream, hails, byrds and possibly engine room slightly warming your hands and feet while flying in a cold weather.

Musculair I was 28 kilos..and flown with father and daughter configuration..with musclepower of course. Garbrick built a 90 lbs plane for his son and he flew it..a teeenager. Airy-Plane is the smallest twin ever by Wilbur Staib.
