My favorite weekend "beater" has a wing loading of 53 oz/sq ft, of course being a bit bigger helps due to the fact that everything is a bit more efficent as you get bigger. You won't have any problems as long as your P-51 is straight and the CG is good. If anything set it up a tad on the nose heavy side, then when you pull off the power it should establish a nice glide which will help on landing. Best of luck, it's a pretty model.
