Scale question
On the subject I am building (scale bolkow-graupner) I notice on the full size that all along the tail boom at the top failring on the outside there are metallic bits, (like small child spoons in shape) retained by a screw on the both ends at intervals? Can anybody tell me what these are for? Is it to do with lightning orwhat? They also are at intervals around the edges of the panels that open on the sides and they have me really puzzled.I want to reporoduce them on my ship, they are no bigger than a baggage clasp but different and obviously serve a different purpose.

i believe yo uare talking about the fasteners. one screw (or fastener is actually the one you undo to pop the hatch or cover off/open, the other is actually permanently fastened there to keep the screw/fatener there so you dont have to put it somewhere only to have to search for it later. sort of having the screw kept from being lost i guess. many times they are unpainted because they are very often removed or unfastened and they flex. paint would not like all that flexing.drive a rotary, fly a rotorcraft

I know the fasteners you're referring to sky because I have them on my sheet, but its not those squarish ones I mean, but the type with the two screws mentioned above.
Thanks for that info though.

Those are called Dzus fasteners. they screw in a quarter of a turn,latching onto a wire stretched across the underside of the aircraft skin of the aircraft, used extensively on most aircraft, for cowling, panels,etc.
