These guys had a booth at Sun N Fun but I can't figure
out if they are setting up a stock scam or just naive.
Swift Engineering has a track record but the Samson company
is management heavy with light weight engineering.

The ducted fan (if it flies) is not going to give them 22 mpg
that is for sure.
Freedom motors is another Moller stock scam. As far as I can tell it
is a phantom company. Nothing produced.
Preliminary Specifications:
# Estimated MGTOW = 1360 LB (Maximum Gross Take-off Weight)
# LENGTH = 15’- 6”
# WIDTH = 6’- 4”
# HEIGHT = 4’-1”
# SEATS = 2
# MAXIMUM SPEED = 95 mph on wheels, 140 mph flying
# RANGE = 500 miles ground, 220 miles air
# MPG = Estimated 48 mpg ground, 22 mpg air
# WINGSPAN = 19’ – 5” main, 6’- 4” canard
# WING AREA = 88 S.F.
# WING LOADING = 16 psf
# ENGINE = 120 hp Freedom Motor twin rotor
# ESTIMATED TBO = 2500 hours (Time Between Major Overhauls)
# FUEL = regular unleaded automobile gasoline (any fuel capable)
# FUEL CAPACITY = 10.1 gallons including reserve
# STALL SPEED = 55 mph
10 gallons of fuel is not going to get you 220 miles.
With a BSFC of .5 or worse for a charge cooled rotary engine
100 HP is 50 pounds per hour or 8 gallons an hour or
1.25 hours or 125 miles at 100 MPH. Freedom motors is
probably lying to Swift about the fuel burn.
The canard span is too short so the main wing will stall first.
Apparently there is no real facility as they are not publishing a brick
and mortar address or email address. They want you to use the browser
to send them your name and address.
I hope this does not turn out to be another black eye on the rotary
engine.
