Now I think a 109 lb rotary would be perfect for this. Very impressive.

A great job of engineering but 10 GPH for a 200 HP 2 stroke
is BS.  a 2 stroke is lucky to see a BSFC of
.65 pounds of fuel per HP hour. That means 130 pounds
of fuel per hour or 21 gallons an hour GPH.

5 gallons of fuel would weigh 31 pounds giving an endurance
of 15 minutes. Range at 63 MPH would therefore be 16 miles.

The engine was probably an OMC or Mercury outboard motor.
Although an air cooled version would make more sense.
Flying out side in a cloud of dust would make it un
flyable :)

That will make it a good James Bond movie prop :)

An ultralight helicopter makes more sense.
