Cool! At 1/1 scale, if you switched to a hydraulically-actuated undercarriage, you wouldn't need that huge pneumatic ram and its air bottle mounted behind the MB.5's cockpit. A bit of R/T reorganization and, hey presto, instant space for the guy-in-back
Two of these side by side on the same wing would make the F-82 look weak!
And with two fuselages in the kit, you're already well on the way
