Think about the extreme testing the FAA would demand for a certificated two-control takeoff on the Coupe. Note that the projected gross weight of the Coupe Cruiser is 1500 lb. so it can't be certified under the LSA rules. I think that he was planning to make the plane as a kit. Therefore, it would, I trust, qualify as a 51% Amateur Built Experimental and could go with either configuration of controls. As Fred Weick said, the side loads on the landing gear are really not all that great in the crabbed, cross-wind landings. You might persuade the designer to make sure his landing gear can handle those loads.
