Hi there
Glen has sent us some more CAD images and I've added them to the News item.
Looking at Jessie's linked shot of a -3, the top of the fuselage looks basically level with the horizon, whereas the CAD view will have a distinct tail-down sit when the wheels are set horizontal. Perhaps the mainwheels are too small? - they do look small compared with Jessie's photos...
Does the cut-out for the arrestor hook look a bit big in the side view?
All the best
Rowan
