One purchase lifts a whole small-scale build: upgrade sets for 1:72 helicopter models combine photo-etched parts and masks drawn for the same kit, so nothing has to be checked for compatibility afterwards. The listing covers a set for the British Chinook; which seventy-second kits get combined equipment follows how widely they are built and how much detail they repay.
If no combined set exists for your machine, assembling the equivalent is straightforward: metal comes from 1:72 helicopter photo-etch, and stencils from the mask section. Machines worth the effort are in 1:72 helicopter kits, and every scale is summarised in helicopter upgrade sets. Always check the intended kit: masks and etch fit only the moulding named in the title.
