Shaped masks for the glazed cabin of the Czechoslovak Aero HC-2 and HC-102 Heli Baby light helicopter in 1:72 scale.
Responsibility details are not available.
The Heli Baby was a two-seat machine with which the Czechoslovak design school announced itself in helicopter work in the 1950s. The cabin, shaped like a glazed teardrop, sits on a truss tail boom and the whole thing looks more like a flying scooter than a military machine. The HC-102 version received a different powerplant and with it more power. They flew mostly in training and in light utility work, and the machines built were counted in dozens, not in hundreds.
Rounded glazing has not a single straight edge to rest a strip of tape against, and the frames run across it in complex curves. Shaped stencils solve that by being cut to the developed shape of the part, so they do not wrinkle on the curve.
Lay the film down from the most convex point toward the edges and press it home gradually, not all at once. If it does lift somewhere, it is better to trim the loose corner off with a scalpel and fill in with a strip of tape than to pull the whole stencil away and reapply it.
Before you start spraying, think the sequence of work through. On these machines the glazed cabin is cemented in early and afterwards you can barely get at it, whereas the tail boom and the rotor can be added at any time later. So leave the masked and sprayed part sitting in the fuselage and finish the rest of the build around it. That saves you repairs in a place a brush can hardly reach.
