Not many of those Hyperbipes were built/registered. I remember as a kid in the 70s reading my dad's aviation magazines and the plane appeared on the cover of a couple of them. Always thought it was cool but now looking back it seems a pretty antiquated design, steel and plywood.
RON, THE PLYWOOD WINGS CONCERNED ME.. MY BROTHER INLAW WAS AEROBATIC TRAINED... THE HIPERBYPE WOULD HANDLE ANYTHING HE COULD DO.. NOT MANY AROUND.. LOVED THE TWO STICKS WITH SIDE BY SIDE SEATING.. I THINK I REMEMBER SPEEDS AROUND 175??? NOT SURE, IT WAS A GREAT EXPERIENCE A LONG TIME AGO.
Well, lots of airplane construction techniques can seem antiqued I suppose. Tried and true! Maybe I should say the aircraft's design seems a bit antiquated, but hey, it's got some roots in a truly beautiful antiquated biplane :
