BSFC vs gas mileage, 2 stroke vs 4 stroke

Great anecdotal evidence Mark, thats what I'm talking about! Same
fuel burn, double the climb. The key of course is that less work
(useless work) is being done because your kite has less mass. You're
moving the same payload, just less airplane. I'm sure you can land
way slower at the end of the day.

the reason i ask is my 618 GT 500 burns right at 3 1/4 GPH, as does a
frineds 912 powered GT 500,

and mine will double his climb rate !


Kite ??

a similar plane has apssed all the FnAA testing just as the big boys
did,

and its empty weight is 595, not a kite by most folks standards,

and the fuel burn isn't exactly anecdotal, but carefully measured,
including injection oil for about fifty hours of flight time, part of
which was 1000 mile round trip to Osh kosh,

it will haul two large people, comfortable too, and roomy, if a nit
clumsy to get in due to sitting empty on the tail,

carries 17 gallons of fuel too, and with a reserve, will fly five hours
at 85 cruise, 5400 RPM,,,,,at 3 1/4 GPH

surely not sluggish even with full fuel and two up either,

maybe twice the fun of GA at half the cost,

can't say it is checp though, gravity being what it is !
