Do you mean the Guppy? The Guppy was built by Sorrell Aviation as was the Hyperbipe.


Ah yes, the Hyperlite was a later model...

The Fisher Flying products 404 possibly could be made PT 103 and also Raceair Micro Mong and Lil Bitts. They would be woefully underpowered setup to be legal, and the builder would have to be a master at weight control. There was something called the Polecat that was an attempt at a full aerobatic biplane. Belt drive to spin a big prop. I think a couple were built but not really a commercial aircraft.

I would go with either Fisher sides and bust into LSA so you could have an engine to pull it around.

You lot on your side of the pond live a very sheltered life :)

The Aviasud Mistral was quite successful here in France and there are some good used examples still around for not a lot of money. Someone even made a twin which got through the French ULM regs but goodness knows how as ULMs (ultralights) are only supposed to be single engine.

The Cub was also around for a while in the UK and there are one or two restoration projects still on the go.

However, in the modern world the best one that's still in production has to be the Sherwood Ranger ST, a superb two seater biplane ultralight that is available in kit form with a range of engine options (Rotax, D-motor, Jabiru) so even ham-fisted US amateur builders can put one together in a brace of shakes ;)

The Fisher 404 is definitely not an ultralight, though it was originally intended as one.

The Ranger is my ideal of what an airplane should be. But, not an ultralight in the eyes of our FAA.

"THE RANGER ST (Microlight)
Definition of a Microlight is a 450kg 2 seat aircraft with a stall speed of less than 35 knots."

The Biplum is a cool little plane but not for the big and tall crowd. Useful load is 95 kg/209 lb, so with 5 gal/19 liters of gas the max pilot weight is only about 81 kg/179 lb.

“How about Maurice Guerpont's Biplum?“
That’s pretty cool! Looks a lot like a biplane Cloudster. Hmmmm......
Sorry, stanislavz, I'm not quite sure what you mean. Are you asking what is the appeal of an ultralight biplane?
