I have a Stinson 108-1 and have owned it for the last 21 years or more. It's a flyer, fly's every year, all year and has the Franklin 165 exchanged for original 150hp. Franklin engine is an opposed 6 cyl. and "inverted" doesn't apply. That applies to inline engines for "inverted" and "right side-up"
CFI and A&P
PS I used to fly a Bell 47 helicopter that had a Franklin and those engines were VO or vertically opposed engines. They stood on end.
PSS I agree with others, This photo is an L5

I owned and also took my check ride (1971)IN A 1947 STAION WAGON. THE PLANE WAS VERY DOCEL AND ALMOST IMPOSSABLE TO STALL. GREAT X COUNTRY PLANE.

this is an l-5 not a 108. own a 108-3 station wagon. the franklin used in stinson 108 are opposed 6 cyl engines 150hp or 165hp mounted " " rightside up.

The photo of VR-HFD does not show a Model 108 Voyager. It would appear to me to be a L-5 Sentinel "observer" model that has been converted to civilian use. The horizontal stab on a 108 is located much higher, for instance. What country is "VR"?

I took my private test in a Stinson Station Wagon in 1963. Don't know the year of the plane. Comfortable, quiet ride. Original models had an inverted Franklin engine in them, but the model I flew had the "right side up" engine, still a Franklin.

Stinson also made a model called the Flying Station Wagon which was almost identical to the Voyager. I saw some at Detroit City Airport in 1946 and later.
