Joe,

That'd be a great article! Just not for MAN. Of course because everything at there "fly's great with just 2 clicks of trim..."
The World Models Cap looks great but it has a thinner airfoild than the H9 and the wing planform is slightly different. It doesn't 3D as well.
The YW? Yellow? It's a tank. I also think that it's the ugliest line of non-scale, scale aircraft availible.
I agree with your learned assesment of the Extra line of aircraft... Like watching pattern
I own a H9 Cap (big & small), and have access to a WM and a Midwest. We could put together an interesting read. That is when the wind stops blowing and snow stops falling here n Detroit.
