The First model 1-26 Standard prototype flew in 1954 and
entered production in 1955. Later a kit version of the
Standard was produced by Schweizer and was designated the A
model. This model was then produced at the factory and
designated the B shown here which was essentially the same
as the Standard and A models.
With the 1-26C, the wings were fully sheeted in aluminum
rather than only back to the drag spar with the ailerons,
rudder and elevator still being covered in fabric as in all
previous and subsequent models.
The D model incorporated the first dramatic change in the
1-26 with the advent of a more drooped nose section to
increase pilot visibility, and new shape to the canopy and
instrument panel bulkhead and the new raked squared off
vertical fin and rudder.
Finally with the E model which was the last to enter
production in the 70s, the same changes as in the D were
incorporated along with an all new monocoque aluminum
fuselage with the aft section now being an oval cross
section instead of the previous model's triangular shape.
All told, 700 1-26 sailplanes were produced by the
Schweizer Aircraft Corp. making it the most popular and
numerous sailplane in the world.

The TMRC 120", 96" and 80" span E model 1-26
models are all constructed as true to the
all-monocoque method of the full size as we feel
possible, providing scale realism and the ability
to add even more detail such as side hinged canopy,
fully scale instrument panel, piano hinged dive
brakes doors, fully built up and fabric covered
control surfaces and more.
