RE: as scale as it gets
My scale ability is nowhere near top gun level but I do build both statc and flying models. I am building a 78" Spifire Mk5 for static disply. It would not take away from the detail to put it in flight but it would add some complexity. I would love to see it take to the sky but I am happy with my baby on the ground where it is safe. My piont is if the builder of the spit had the desire to make it rc he could have without sacrificing the detail he put into it. I believe you can even but a 1/5 scale Allison engine that runs! If he was as detailed with the mechanics as he was the appreance I bet every guage in the thing would work and it would be controled by the yoke and pedals. I guess the only real challenge would be building a radio control pilot.
CHECK THIS OUT! THIS GUY WAS WAY OVER THE TOP.
