Thanks Al, I appreciate your help. I can see what you mean. I'm going to include the method you describe to check things out more.
I dont know if you are familar with the APM system, this is a print out of the model I did.
Unfortunately it doesn't account for human error or the slight distortions you get on a printer. I can see the nearest wing strut is a fair bit out too
.
I'm not sure I've got the wings tips right either.
It certainly pays to get a view from someone else.
Cheers mate
Terry
