Keith -
Nifty little ACES II you've got there. I'm basically a 1/35th Armor guy, but work with Boeing in the F/A-22 program and am familiar with the ACES seat (F/A-22 uses a "Modified" ACES II). Might want to get some feedback from "Mother" as he is a scratch-building ejection seat genius. Only thing I'd suggest maybe is adding a piece of yellow coated or painted wire to represent the "D-ring" ejection control handle on front of seat. Great "little" build.
