F-22 Raptor v2 (4)
The largest change was a total re-do of the undercarriage, then I changed the wedges closest to the cockpit to 45* ones (to fit a longer cockpit). The engine intakes also were enlarged, which the new undercarriage made possible. And finally, new landing gears. I can get the from one to retract, but the angling of the back two make it difficult.
