RE: looking to build a warbird
Keep in mind that if you are looking for a scale Stuka in that size range, and plan to super-detail it, the plane probably will not fly very well because of excessive weight and very high wing loading. Our Stuka could be flown with a .46LA but if would need to be built and covered light - with little or no scale detail.
The Val would be a better choice because of the large wing area. You could add quite a bit of detail and still get gentle, scale-like flights from a .46LA.
