I have to admit he does bring up a good point. I have often wondered
what the difference in strength's and weakness would be if I used
different wood in my plane, or enlarged the components for a larger
pilot.

Which is probably one reasons designers don't provide the equations. Many hate
it when folks make changes.

your honour I sold the guy the plans, I provided him with the worked
design calculations showing how the design was arrived at. the
comments in the calculations show how the material sizes were arrived
at. he has made changes to the aircraft which are neither in the
original designs nor show any validating calculations so my conclusion
is that he just guessed at the changes and proceeded blindly.
I cannot see how I can be held responsible for the stupidly
incompetent actions of others.

sounds like a defense to me.
