RE: Which WWII Warbird?
A Ziroli Stuka with the Sierra struts (Ziroli stocks them) and you can run over anything. The Sierra struts are $25 more than the Robart ones but are 25x better, plus they come with a mounting block that fits right into the rails that are shown on the plans. Take a look at the pics on the Ziroli website.
It flies much like a low wing sport plane, probalby more so than any other "warbird". It will also land slower than most of the fighter planes mentioned in this post.
