Images of
Stinson model 108-2 on skis. These are Federal model 3000
skis. Note that skis are used only on the main gear. Ski required
on the tail wheel only in deep snow. When landing lowering the
tail without the tail wheel ski causes it to act like a brake.
This airplane is a model 108-1, 1947, with 180 hp Lyc IO-360 and
a wood prop 76x54. This airplane is now flown in the experimental
category. Image is color, about 137K, added 03/25/10

The owner tells me he normaly flies without the fairings at the
landing gear. Take of distance on hard surface with the owner
(220 pound) - and fully loaded with fuel - is just 360 feet.
(nill wind and 55 F.) Which is very impressive when you consider
the airplane has a 54 inch pitch cruise propeller. Belive it or
not, the speed has now increased (!) with additional 2-4 kt
(crusing at 2,200 rpm) and the need for trim is less than
before!
In take off position you lift the tail from the ground/ice as
fast as possible, normaly it takes just some twenty yards before
the tail is rising. Forgot to tell you that I use DOUBLE front
safety wires (5/32) in this installation, and 5/32 springs in the
front, instead of shock cords.
The springs (and one of the two safety wires) are mounted at the
engine lower engine mount fittings. The second safety cable is
attached to the Stinson ski-fitting, bolted to the landning
gear.
By the way, leaning to best economy at 2.200 rpm (then speeding
90 kt) the engine burn just about 7,4 gallon/hour.
Weight and balance is with the Federal 3000 skis is of course
different: The payload for this beauty is normaly 897 pound. The
weight of the Federal 3000 skis, with pump, oil etc are 132 pound
- so with the hydraulic skis the payload decreased to 765 pound,
witch still isnt bad, I think.
Due to balance problems (in worst case) I always have to load at
least 60 pound in the cargo appartment. I always carry a lot of
extra emergency equipment and fuel (duty of flying in mountain
terrain) so its realy not a problem for me. Added 03/25/10.
