XL-79 progress

[Jeff XL79]

Leonard knew there was enough variables that in certain spots making a mock up was going to be the only solution. When I built mine there was string and duct tape involved. 
The practice of mocking up and verification should have been my method from the beginning.  For example, the landing gear angle and geometry needs to be built using the actual fuselage measurements and calculated wing leading edge location. With a plumb bob and a level fuselage you can then determine axel position and actual forward angle degree. 12° is an approximation. 
Study the plans, make mock ups, stick to conventional methods.

Finally got the seat built. Used webbing and large headed rivits.  Each webbing can hold 1500 lbs. Ends where rivit goes through are double and triple layers at the rivit. It's very comfortable and I don't think it'll give me the dreaded waffle butt.

Jeff XL79,

I too was looking to do nylon webbing. Curious as to what your seat weighed in at? Leonard has said the aluminum strip seat per plans comes in a little under 1 lb.

Pretty tough to weigh it with it in but I would guess it's right at 1.5 lbs. You could always take the equivalent length of webbing and weigh it separately. Still pretty light.

Good morning,

Jeff and Steve, I weighed my seat before I installed it. It is per plans from the original design (not the XL). It was 1.5 pounds, 1.6 with the rubber welting I installed between it and the steel tube.

I weighed everything as I installed it or fabricated it. I put that information in a spreadsheet in the hopes that it would be helpful later to myself or others. That can be found here:
