RE: 1/8 scale TopFlite Corsair Mods
Here's and additional photo of my finished cockpit. The pilot you have will fit well, and be mindfull of the weight. Mine doesn't have anything below the waist, and I even trimmed off his shoulders in width so it would look better. The pants are folded in on themselves at the knee, to give the impression of a full leg when looking in the cockpit.
Watch the height they sit in the cockpit, I don't have the seat because you wouldn't see it anyway. In the earlier photos, you can see the pilot is sitting higher than the finished. Those were before the surgery.
