How it's made. Five printed parts in PLA, all flat on the bed, no supports: the fuselage (152 mm nose to tail with the canopy and the nose axle grown in), a 180 mm one-piece wing and a 70 mm tailplane that push through snug slots in the body, a swept fin whose tab drops into a slot in the tail, and a 64 mm two-blade propeller. The propeller's bore clears the 6 mm axle by 0.4 mm a side so it spins, and the rounded nub on the axle's tip is larger than the bore so it can't slide off — the same joint the Car Kit's wheels ride on. The tail number is set 0.8 mm into both sides of the fuselage and filled in the second color.
