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.

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.
