Welcome aboard, friends
@ Don - I was pretty sure the the choice would please you
For a single-seater, the Fireball has a bulky fuselage. For the model, it is good because there is a solid floor plate that doubles as the front undercarriage compartment ceiling.
The parts behind the pilot’s seat are not long enough to reach the cockpit bulkhead, despite being marked there. As the base of the seat back panel is clearly marked in the cockpit floor, I aligned the parts according to the base.
