    I didn't know there were Powered Hang Gliders - I will have to look that up.

    If I were to take up this challenge, I would do it with 'construction foam' and 'packing tape'. I use the same materials when building my 'ZAGI' flying wing radio controlled gliders. They are extremely strong and I haven't been able to break one yet. From 1000 feet up, I can smoke it into the ground without any damage. I would scale it up to whatever payload desired.

    I once broke a surf board in Long Beach, California by having two many women sitting on it, while stretched across between two beds in my hotel room, to provide extra seating. When the board broke, I had a good look at just how minimal those materials were, and how strong the board actually was. When I started flying the ZAGI r/c glider, I was equally impressed by how strong packing tape was, when used as a tensile skin, so to speak. These inexpensive gliders are extremely tough and in the last 10 years, I have not been able to destroy one while using it for air-to-air combat. https://zagi.com/

    Not overly common and I’d guess (not flown one) that they’re more cumbersome to operate than PPGs. The PPG backpack is quite a neat “installation”. Improved designs (compared to above) quickly encroaching on flex wing microlight territory.

    I wish there was something more aeroplane like in this division.

    Someone mentioned that even if you could design and build a flyable 50 kg empty ac the officials would ruin it..starting to demand this and that.

    That depends on your officials. In the UK there is a sub 70kg class which is pretty open.

    Even still, 50kg really is not a lot of mass budget to play with. More plane really does = more mass.

    Comments from an experienced ultralight designer and producer, copied from another forum about producing an electric Part 103:
    Dale is the designer and former producer of the Lazair. Link to the thread is https://www.rcgroups.com/forums/showthread.php?1412424-100-scale-Electric-Lazair/page45#post34307141 and was first posted here by Speedboat 100 (thanks) in another thread.

    I have actually tought of two rubberbands for a 1/5 scale R/C model. It would be the first...but proving my concept efficiency.
