They are nice planes! I have seen a couple of examples. One was really gorgeous.
The plans call out a special tank with only two lines. If you read the construction article, it explains exactly how to deal with that, and it makes perfect sense. I just built one for a friend.
Pick an engine you are sure will be a steady runner, because you won't want to lose this one if the engine dies in the wrong place. A Medallion would be good if the plane was light.
As on most half-A's, watch the weight. Since this one is designed like a big stunter, if you don't keep your thinking in line with the scale of this plane, it will end up heavy.
I have a Pinto kit that someday should get assembled. Got to finish up some of the other partially assembled nightmares filling up the shop right now....
Go for it!
