Sailplane wings, which without doubt are the most efficient wings in the air are long and narrow.. This gived the exact opposite of your suggestion, a very extended leading edge to main spar area. The area from the main spar to the trailing edge is kept to a minimum .

I suspect that like us your ultralights grew out of hang gliders with little engines screwed on. We managed quite well for a while building and flying without interference but then there was a series of well publicised accidents and the CAA stepped in. Luckily Ann Welch, a long serving and well respected member of the British Gliding Association got imvolved and managed to get the same autonomy for the fledgling ultralight community that the Gliding Assoc had managed to retain. This gave permission for us to get on with our own organisation as long as we kept our respective noses clean. This has worked well and I think that since the introduction of `Section S` which laid down a standard for build quality and specified what an ultralight is in law there have been no structural failures. We have never had the freedom to build and fly whatever we liked that you seem to have in your experimental category. I am not sure if that is good or bad!!!!!!

If he sees that your work is of good quality he will probably accept your figures. If not....., after all he is signing the machine off as flyable. All ultralights here are supposed to be weighed at their annual every five years to ensure that it does not exceed the MTOW which defines an ultrlight in law. People add, radios,spats,extra tanks etc., and if you are not within the law then the insurers will wriggle out of paying for any accident.

Lehman" Subject: Re: Kolb-List: mo CG --> Kolb-List message posted by: "David M.

If you want to know everything there is to know about aircraft W&B, curl up in front of the fire and read this book... The FAA has their own W&B book, "Aircraft Weight and Balance Handbook", FAA-H-8083-1... It will instruct you how to perform a W&B on a 747, although the theory is the same for a Kolb...
