Really nice work there John - I like the attention to detail. However, given that the Me-262 is a favorite of mine - I’m still not convinced about the leading edge slats being in the stowed position. They were spring loaded and only retracted when airborne due to the force applied to them by the airflow at speed. When correctly calibrated, they deployed at a certain airspeed for approach & landing and of course the take-off. They would never be in the stowed position unless lock-wired into the stowed position for transport; but, this was rarely done as it caused problems in recalibrating the springs. However, you are doing a beautiful job!!
