Full Scale Mockups do have their places in museums, and those created from mouldings of original aircraft such as Tallichet's P-40's and P-51s' or the spitfires in the UK show what can be achieved, others can be built as composites of fibreglass, timber, metal and even incorporate original structure like the Halifax at Yorkshire in the UK.
Other than providing for a polished bare metal finish, I am not convinced a metal FSM is actually going to meet or exceed the quality of the moulded fibre-glass examples, or is worth the trouble if moulds exist already? in this case it would be interesting to see the difference in the current P40-B project mentioned above, and the outcome of modifying an output of Tallichet's fibreglass P-40 E moulds?, and smiliarly with a future metal P-51 against the fibreglass examples already existing?
If the FSM is to be painted I cant see any benefit at all in trying to produce it in metal?, of course it is possible to create a non-flying replica based on the same patterns etc used by the reproduction / restoration businesses, fit out a cockpit etc ie duplicate the real structure, but not in airworthy materials, however that outcome is more a replica or reproduction than an FSM?
The advantage of the moulded FSM's is that they exactly duplicate the skin profiles, contours and rivet lines, the only way a 1:1 metal FSM can achieve that is to place sufficient structure to rivet and hold the skins in compound curves, some of which may have originally been achieved by heavy pressing not simply bending and riveting. Of course false rivet lines can be created without any frames or intercostals existing behind the skin, but that risks a wobbly skin that belly's in and out when touched. However the simple problem would be the cost in time and materials to duplicate the skin and rivet lines in metal.
In the end if significant compromises are taken to keep the costs and effort down, an FSM can start to look like a cartoon characture of the type rather than a museum quality display, while "compromised" FSMs can form the basis of film set extras in the background or for action/demolition shots, "if it does'nt look right" I am not sure they really have a place in museums given the space they take up, unless the type is essential to the purpose of the museum and cannot be presented or acquired in any other way?.
I look forward to how Avn-Tech and Leon will address some of those difficulties in the metal 1:1 full scale replicas being built to Museum Quality?, and look forward to seeing the photos of work in progress and the finished products, as I said earlier FSM's do have a valid role in museums.
Below is a scratch built DH-89 Dragon Rapide, and DH-61 Giant Moth both in Fibre-glass, the Dragon Rapide is outside Hotel at the former Speke Airport in the UK, while the DH-61 is in the Qantas museum at Longreach Australia.
A Fibreglass P-51 is in the American Air Museum at Duxford and a Spitfire on a roof in Canada - Fibreglass being the material of choice for outdoor FSM's, with many fibreglass Spitfires replacing real ones as gate guardians in the UK at RAF bases.
