Unknown fusalage

Rich,

Not sure if it's of any use but I have attached a copy of Pat's ASW22 wing root template for a comparison.

Cheers,

Mark.

Richard,
Attached is a pic of my PT ASW20 Fuz & rudder.
The fuselage moulding is 1850 long.
If you are going to Woodspring on Sunday, then bring the Fuz along & Pat says that he will be able to tell you instantly if it is one of the PT range.

With the modern glass ships over time designers from various manufacturers have come to the most efficient fuselage shape. The result is that there is not much noticeable difference in shape anymore. The key is to reduce the fuselage surface area as much as structural possible. In doing so the surface drag is reduced and glide angle improved.
The glide angle of a glider or any other plane flying without engine power is the ratio between flying weight and total air drag at a given speed.
Sample, if a glider flying weight is 300 kg and the glide angle is 1:30 the total drag is 300 divided by 30 is 10 kg.
For model scale gliders this is the same so reducing drag as much as possible will improve glide angle. Note glide angle and minimum sink rate are two different subjects and happen at different speeds but that is a story for an other time.

Just for interest-
The Pat Teakle fuse is the one at the top and the unidentified fuse is at the bottom.
