From memory, the differences were slight. The wing airfoil was different.
The W-10 has a curve on the bottom where the W-8 was flat. I understand
that there were 2 or 3 inches of extra width in the fuselage. Also, the
W-10 was stressed for larger (Lycoming) engines. I built the airframe for a
W-10 and talked with Mr. Wittman about it a couple of times. I also saw him
at Oshkosh several times and talked with him in person once. He was a VERY
thin man and medium height. I can easily understand the change in the
fuselage.

He did not think much of people who put in Lycoming 0-290's or 0-320's (like
I was going to do). He much preferred the 85hp Continental. When I talked
to him, I found out that he was turning his little engine at about 3,200
rpm -- way, WAY over readline. It was putting out as much HP as the larger
(and heavier) Lycomings. He did say that he had to overhaul it about every
400 hours. Since he did it himself (rather than hiring an A&E), he did not
think that it was a problem at all.

W-10 fuselage is a little bit longer and has a bit more room in the
****pit area (especially if built as a "C" model - ala Jim Clement).
The -10 will carry a larger motor (if you really want),
very effective wing tips added,
reshaped fin and rudder,
and slightly larger stab/elevator.

The FIRST W-8 wing was a flat bottomed affair.

The "round" airfoil was first flown on the W-8, which leads to some
confusion.

It was incorporated into the -10 along with the trucated triangle wing
tips.
The wing is all-wood, laminated spars(?), truss ribs, and plywood skin.


Most of the new Tailwinds ar W-10's with O-320's in them.
They average 750 to 850 pounds.

And yes, there are a few O-360 powered dragsters flying.

My W-10 has an O-290-D2 Lycoming (rated 135 hp at 2750?)
I'm trying to keep it fairly light, but functional for cross country
flying.

Mainly, I want to keep it as aerodynamically clean as possible.

Anybody remember a Turner T-40 named "Ophelia Bumps"?


A friend had an O-200 powered W-8, which is a sweet machine for her age.
Cruises about 155 mph...
