We tested to a 5 g positive, 3 g negative load and all the tank supports did was
laugh at our attempts. There's really no possibility of the mounting tubes bending.
The only way for the tank to get lower would be for the perimeter of the
fuselage to collapse. The way the tank braces are made makes even this very
unlikely. I may have a couple better pictures of the setup. If so I'll post them
in the next few days. Also, remember the factory setup puts 12 gallons of
fuel on those tubes WITHOUT stiffening the tubes as we have.

I did a short highlight of our trip to Monument Valley and some of the
activities after we and the MV gaggle returned here.

Okay that will be good to see a clearer picture of the tank area. I took some more
pics yesterday when I came back of my set up, and as soon as I can remember
where I put the camera I'll post them. I really should take some pics of the
tanks themselves, as in my design they take quite a bit of the structural load.
But I also added some lower bracing and some lateral bracing in tension to
keep the tanks from wanting to strain on the frame outwards. As someone mentioned
years ago not till I am on my third Kolb will I be able to get it all just
right. right now my main emphasis is to build it strong and if its a few pounds
more then so be it. I will have excess HP so in all I don't expect it will
affect performance all that much if any. All I want to do right now is finish
it some time before the end of the century. :-)

Here are some photos from my trip. It was good to see many familiar faces
again, especially Tom and Betty Kuffel, and to meet some new ones. Always a
good time.
