Personally I don't get it. Is this so A) you can keep the airplane at home & drive it to the airport where you convert it back into flying shape, B) To drive home when the weather grounds you, C) To drive around & get surprised looks from everyone, or D) all of the above?
I'm sure it's more airworthy than any of the goofy "flying cars" I've seen. But going 55 or 60 down the freeway on tailwheel gear looks to me like a groundloop waiting to happen. I didn't see the tailwheel/motorcycle turning, so does that thing have steerable mains?
Looks to me like yet another solution in search of a problem. If it's about taking an airplane down the road (to an airstrip or wherever), it seems to me like a trailer behind a skookum truck is a better way to go. BTW one of my hangar neighbors just bought a brand spanking new 16' double axle flat trailer at a place near Chehalis WA for like $3K. He told me he'd seen used beaters around for sale for more. A couple feet too short for my airplane, but would probably work for a Pacer or something similar. An 18 footer would do the trick nicely for mine.
