Default RE: Redesign and reconstruction of the Oldest Taurus on Earth

Gents, for who is interested.

Some Taurusses on one picture.

The Contest Taurus(1) and the transferred standard Taurus(2) made with some photo shopping, while I am waiting in the painting process.

As a designer, Ed employed many small details in his narrow Contest Taurus. All of these would have been difficult to reproduce by the “Man in the street”.
The Standard Taurus has to be a plane that fly as nearly as good as the Contest Taurus of Ed himself but with some modifications to make the plane easier to build and maintain.

BTW we see this in nearly all the contest planes when they ‘kit’ them. To make building easy and difficulties less.

What did Ed and Frank, his draftsman, change to make a standard Taurus from his contest Taurus.

I show you the changes I did myself by photo reconstruction, of course not scaled.

Reference is my own Taurus (3), an visual exact copy of the MAN Taurus of the magazine.

• Ed did give the fuselage more internal height near the radio equipment . Result the green horizontal dash volume, so more room for the radio equipment. Important when you do not have “relay less” as Ed did have oder Graupner Varioton oder Telecont?.

• The engine and tank relationship (level) was the same but after the modification of the fuse there is extra room beneath the tank, for batteries, Green bended dash in the tank and battery compartment. So the engine did get the high position in the fuselage also to have more clearance for the prop. Of course the spray bar of the engine’s carburetor is in the centerline of the tank!!!

• The tail cone Ed did make a little longer (Blue vertical dash) as we all know now.

• The fin and rudder did get a steeper angle on the fuselage and the rudder a little smaller(red), as result of research. The tail cone of the new Taurus was made longer that’s why!

• The bottom line from the tank compartment and the tail cone did get a other angle to finish the new shape.

• The fuselage became more wide and if you could not fit your radio even wider.

• No adjustment for the engine, the angles are fixed for side thrust and the down thrust. This was the result of research.

I think the modifications do have the most negative influences on inverted flying because of the angle of the bottom side of the tail cone so more turbulence! Also the thrust line wasn’t neutral anymore. For this reason the Oldest Taurus on Earth, Contest Taurus (Wester Taurus ) is better than the standard Taurus and later Top Flite Taurus.

The Top Flite Taurus is of course much better than the Orion (picture 2) with his "tail high" ATTITUDE (picture 3).

See also my post 465 page 8/10/2008 page 19 of Ed Kazmirski's Taurus.

So, continuing the painting.
