In fact, there is the floor for my garage which a quick visualization would assume it to be appropriate for the loading described, however there are a few trees in the way, as well as probably 4, maybe 5 residences that fall within the 400 foot radius. However, if you could get it off the ground on the east side its on a hill side and you could get it over the houses, but it would shoot the heck out of your 5foot bottomw because the houses are all like 15 feet tall, and the trees more than that.
Now the Pullman airport is having to relocate their runway to orient it differently, I would guess that once they get the new orientation worked out, there would be a chunck of asphalt at the end fo the runway that would be perfect,,
now in your 11,000 pound pull test, does that accomodate for non limited wind and thermals? because that a whole different kettle of fish,, and a Citabria would not be stressed for the 20 plus G loading in the squares,,and based upon watching you set off for officials without taching, I have some concern as to what would happen should you get a lean run on your Citabria, the handle tension would be a bit stiffer dont you think?
