I toured the production facility a few weeks ago and test flew the prototype. It is an impressive airplane. Philipp Steinbach is equally impressive, he is a talented engineer and seems to have a clear understanding of the business. The business is backed by a Walton and has plenty of cash; hence, Bentonville. They are working to create multiple revenue streams from their composite manufacturing expertise and equipment.
The plane is crazy light. You can hold the empanage with two fingers. It is very much like a life sized version of a model airplane. Philipp is working with Garmin on an ideal avionics package so the current prototype and web art are not up to date.
Cockpit is comfortable, I am 6' 1" and it was fine.
Not so sure about the "tail dragger training" claim, that is a stretch. The airplane is very sensitive in pitch and roll; it is an unlimited aerobatic airplane after all.
