This is designed for Testor's/Italeri's 1/72 scale Blackbird kit
, and specifically test fitted to the kit No. 145 boxing. This part goes with my SR-71 Engine Spike design.
I designed realistic details into the Engine Inlet, notably the forward bypass doors and the "mice" which were located inbetween each inlet door. The mice functioned by locally increasing parasitic drag, which in turn enhanced pressure recovery ahead of the engine.
I've designed this to fit into the engine nacelle of the Testors/Italeri kit, after removal of the internal mounts for the kit supplied inlet spike. Some sanding on the outerleading edge of of the inlet will be required to achieve a precise fit.
