    When the CNC is built and passed its testing stage.... :rofl:


    I already have one of these units built as prototype to make sure it was fit for the intended purpose,workslike a dream.

    Thing is I need to get the bits at a cheaper rate ie buy in bulk to reduce the cost of a singular unit.

    What do you make the aircraft component structure out of? is it plywood?

    I LOVE spitfires. Form definitely follows function...
    I built a small balsa kit of one once - really satisfying. 1.6m is a pretty big wingspan :)

    I think I would have had an orgasm.

    Take me back to my apprenticeship days laid flat out on the top of a running V12 Rolls with no manifolds on setting the carbs for 6" of blue flame out of the exhaust ports, no H&S, no ear defenders.

    What ?

    Not quite the same John, but did you catch the dreamliner flypast Rolls last month? It was cloudy all day, but they parted just in time.

    Anyway, I let the bowl out of the computer today. I scaled Z independent of X and Y to get a better result, so it looks a little different. Need to glue this up, then on to the next step...

    George,

    Fuselage formers are 3mm liteply. This is a layer of ply, then balsa, then ply. Much stiffer and stronger than 3mm balsa, for not too much weight gain.
    Wing aerofoils are currently 3mm balsa, but may change to liteply and hollow out most of the inner material.
    Stringers and longerons are 1/4" balsa square section.
    Airframe and wings will be 100% skinned in 1/16" balsa.

    Finish probably brown paper and pva, followed by lots of sanding, sanding filler, and finally camo spray and decals.

    John,
    I'm totally with you! Been designing my own purpose made aircraft for many years, but always hankered after a Spitfire. Saw one for real do an aero show at Cosford 2 years ago and brought a tear to my eye . . .

    If you make an electric Spitfire of 2m or more, you can carry the weight of a sound system with real startup sound, full V12 Merlin engine, machine guns etc. from a pair of loudspeakers:
