Looks the best yet, Duncan. A few points:

1) What's your tail clearance in taxiing position? Looks like it might be getting a bit close to the dirt (but I actually kinda liked the T-tail).

2) What's your entry (door) look like? If you're carrying most loads through the strongback, can you go to a single piece windshield?}

3) That main gear is more far forward than I would expect (although not insanely so; it might very well be right). Are you sure you have your vertical CG estimated correctly?

Hi Addaon,
Wow - not a lot gets past you, does it? Tail clearance is about 20 inches. Is that sufficient. do you think? As far as aircraft egress is concerned, I don't know (yet). I can't visualise it, and I can't do 3-D CAD, so I'm going to have to design it once it is a physical entity. I'm hoping to butterfly the rear window from the substantial side-post, which is straight. And you are spot on with the main gear position being incoirrect. It was out by just on 4.5 inches. I'd just forgotten to update the drawing from the calculations.

Cheers,
Duncan
