Ed Armstrong,

on the gross wt of the aircraft; be careful increasing the gross wt.  the
aircraft wing area and horsepower will dictate takeoff distance and the
factors are additive, iow, if you increase you weight by 10% you may
increase your takeoff distance by 20%.  also, the 9 "G's" oft quoted is
"ultimate", not "use". Lancair's tech reps told me that the use load for the
320/360 is 4.5 g's @ 1685 lbs.  it you go to 2000 lbs. gross, this could put
you below the lowest legal limit.(3.75 "g's)and ground you.  remember the
entire aircraft structure and all surfaces and connections would need to go
up to 2000 lbs. x 9g rating, not just the wing to be safe, and they are
rated appropriately, including landing gear brakes and wheels.

hope this helps,

Scott Dahlgren
