Great detail is unnecessary since you cannot buy a new ArrowCopter and I know of no used ones for sale although at least two were sold into the United States (they appear in pictures). Still, it's worthwhile to look at some of its unique qualities.
American gyroplane enthusiasts first saw ArrowCopter back in 2014, only three years after its maiden flight. If you were at Bensen Days that year and admired ArrowCopter, you may be aware you've seen nothing since.
ArrowCopter's aerodynamically shaped landing gear strakes provide lift in horizontal flight, claimed some reviewers, and serve as fuel tanks. This design feature is one of several distinctive ideas that ArrowCopter designer Dietmar Fuchs incorporated.
As ArrowCopter accelerated down the runway, pilots looked for 60 mph (52 knots) and 340 rotor rpm. At that point ArrowCopter is ready to launch. Climb out occurs at 60 mph while cruise speed is 99 mph (86 knots). ArrowCopter's never-exceed speed was 120 mph (104 knots).
Non-gyroplane pilots may not find that particularly fast. Certainly, it is not compared to a fixed-wing, high-powered mLSA aircraft. As gyros go, though, that's fairly quick. It's smooth lines explain much.
What you should know is that gyroplanes are some of the best aircraft in recreational aviation at performing well in stronger winds. This is true of all gyroplanes, not only ArrowCopter.
Here is the video that ranked so high with YouTube enthusiasts:

A dozen years ago, fixed wing pilots thought very little about “gyrocopters” — as some people called them. Actually that word is a model name established by Igor Bensen, widely thought of as the father of this activity along with Juan de la Cierva of Spain, known for his pioneering autogyro work. The preferred term these days is “gyroplane.” Names aside, what pilots care about is having fun in the air and being able to afford a flying machine. When an aircraft also looks terrific, heads turn. From eleven years ago comes the #3 in our list of Top 50 Aircraft Videos. More than 450,000 views of this video show broad interest in ArrowCopter, quite the head turner in its day. Gyroplane interest grew quickly after European designers took the lead from American manufacturers. Think back to the days of Ken Brock’s gyro or the former Air Command (now under new management).

"[However, FAA's] data is not clean," Steve observed. I am well aware of this problem. Uncertainty about data accuracy of "alternative" LSA is why we have reported fixed wing Special LSA, only offering guesses for weight shift trikes, powered parachutes, gyroplanes, motorgliders, and more.
However, we hope that will now change and our market share reporting will be more inclusive. Hurray!
Problems in FAA's database is not caused by incompetent clerks. Agency personnel must sort through inconsistently-reported aircraft. If, as Steve pointed out in one example, the registered name of the aircraft is slightly different, it won't show up on a casual investigation.
He added, "There's no end of that kind of thing …just so we know the limitations on this exercise. But with that understanding, I love this kind of thing, I have the skills to do it, and would be honored to support your good work for the sport."

Chuck's son Jim Vanek took over the business and revamped the Vancraft designs. He said his "award-winning, world’s-first, two-place gyroplane took the prestigious Charles Lindbergh award at the Oshkosh airshow in 1985." The company also reports his Sport Copter II design was voted as one of the Top Ten Best Designs at AirVenture in 2011.
An airshow performer, Jim said he wrote the parameters and guidelines for gyroplane looping for the FAA in 1998 after performing the world’s first loop in a conventional gyroplane, in 1997. The company's website reports, "He is the only gyro pilot in the world that holds an International Council of Air Shows card for gyroplane looping and rolling." Don't even think about trying this yourself, however.
The company said, "We offer 22 thru 28 foot rotor blades of our own design with a lift capability from ultralight thru 1,200 pounds gross weight." They added, "We are the only manufacturer that test flies all blade sets prior to shipping." For export, Rotor Flight will fully build their aircraft but in the USA, FAA will only permit them to deliver kits, the same as all gyroplane producers.
As with all the modern gyroplanes, Rotor Flight uses a substantial tailplane. "The Dominator [series of one and two-place machines] incorporate the Tall Tail design for stability." Asked how their product differs, the company's website states, "What makes the Dominator so unique is its high profile design. It sits up very high off the ground."
