Steve, do you mean, your starboard can, tapered, toward the back? If so, yeah i had the same problem, by as much as 5mm, just to ask WHY?
I sanded out the front of the can, and took the ellipse out fully, this brought the balance to 1mm, maybe a tad under, which i think i can live with, but i cant figure how this has happened, were they sanded flat while making the master, as thats two kits, both with tapered starboard cans?
Also NOT putting a cockpit in, no way.......does look better without, i love the shape of the side windows on this model with there lozenged profile, the cockpit interior ruins that lol.
