Hi everyone, I'm a new Stinson owner and really happy with my 1947 108-2

Thanks! It's got a Lycoming O-435 engine with a variable pitch Hartnell propeller. I flew it from NE to FL last week and she did great...just slower than I anticipated - 90kts indicated at 3500' MSL.
You are finding what every Stinson owner knows, but few want to admit to it. The Stinson is a very draggy airplane, but makes up for it in being the most stable airplane ever built, no matter the size.
I have always believed the model number comes from the design airspeed, 108 mph. That is the speed I get in mine at normal power settings and have for the last 52 years!
Larger engines do not help. I converted to a Lycoming 180 hp 8 years ago and the plane still goes 108 mph at 2350 rpm. It will go 120 or a little over with the Lyc turning red line 2700 rpm but probably burns 15 to 16 gallons per hour at that speed. I have never flown one with the Lyc 190 O-435, with a variable prop, but I would think that might help a little, but still the drag of the airframe is the controlling factor.

Thanks for all your expertise and willingness to share your knowledge on this forum for us new Stinson owners. Did all Stinson 108-2 aircraft leave the factory equipped with the Scott 3200 tailwheel?
Hi Curtis, considering the purchase of a 108-3 with the Lyc o-435 and Harztell prop (adjustable pitch), so same set-up as yours. I am reading of difficulty in obtaining parts for this engine as Lycoming does not support it anymore. Do you have a reliable place to buy parts for it? That is the only factor that is worrying me a little right now.
Thank you in advance
Understood, is the o-435 a 1200hrs between overhaul engine?
