Dials the size of a poppy seed can only be rendered legibly by printing, and 1:72 helicopter instrument panels do what a brush cannot manage at this size. A pre-coloured panel glues in place of the kit part and the cockpit gains depth at once. A panel of this kind is trimmed and test-fitted dry before it is bonded, and the same handling applies to the harnesses, consoles and pedals etched in 1:72 photo-etched sets for helicopters. Printed panels for the larger scales are gathered in instrument panels for helicopter models.
