Last month I started a thread entittled "Landing" and from the replies but not mentioned, was wing loading. It all comes down to, the higher the wing loading, the higher the landing speed most be. What would change if an ARF manufacture produced a scale P-51 with a wng span of, let's say 83" and it weighted 15lbs dry or less. Take a look at BH models and you will notice they already have moved in this direction. I have there GS 83" WS AT-6 and it weighs about 16lbs WET. I powered this plane with a Saito 180 FS and the power to weight is prototypical. I do realize these ARFs are considered sport scale but it would not take much effort to kit bash them.
