Do you think you could squeeze a soda can in between the booms?
And a cradle or frame to lay a soda can on its side would be cool.
I apologize in advance for the following criticism, I realize it's not particularly helpful or useful but it's smashing into the side of my skull trying to get out. Please feel free to ignore it, delete it and/or rake me over the coals for posting it.
Not that my opinion matters
and it's probably too far along for changes, but aesthetically I think I would make the rear of cockpit/fuselage vertical rather than angled, and maybe widen the space between the booms. As it is it looks more like a sleek gunship than a cargo vessel to me.
Also the "Hind" type tandem cockpit feels a little... I don't know "been there done that" to me. Did you try any variants?
Finally the rear thrusters seem too small, have you tried it making them the same size as the forward engines?
Regardless of all that nattering I can't wait to see the finished model and I'm sure I'll be stocking up on several.
