There is a wing life extension mod available that will extend the wing's life by 7560 hrs.
Did someone say you needed a lot of runway to get a Tommy off the ground?
I used to fly into my friends strip in my Tommy and safely out again.
The strip was 260m long! OK, I would not attempt it if there less than 5 kts of wind straight down the strip and it would be lightly loaded but it could and can be done.
Most of my flying was farm strip flying and believe it or not a Tommy can make and ideal aircraft for that type of flying once you've mastered its idiosyncrasies.
So, to the OP, buy one, love it, fly it.
