If anyone's built the Revell F-15C, you'll recognize the area I'm talking about here. I seem to remember having this same issue when I built this as a kid some 25 years ago. Back then I didn't care and just glued it up, stepped seam and all.
Anywho, where the forward fuselage with cockpit and nose gear fit to the main fuselage, there is a size difference in the diameter of the mating surfaces. I'm thinking it's at least 1/8 or 1/4 inch.
Top seam would be manageable:

But the bottom....oh my:

Here's the step in the instructions for clarity:

Sanding, grinding and putty ain't gonna git it here without a major contour change. I thought of bracing the inside of the rear fuselage to push the mating surface outward, closer to a flush fit, but it strains the other seams I've already glued so much they are threatening to crack.
I contacted Revell to see if they'll comp me a kit. Their F-15E is about the same price range, so we'll see. This might be the first kit I've had to toss in quite a while. Pretty bad.
