The DAW Schweizer 1-26 you are currently flying is a rather nice versatile
slope glider when properly trimmed (especially if the glider has been built
with ailerons and reduced dihedral of about 2 degrees). If the glider was
built with rudder/elevator and standard recommended polyhedral it tends to
exhibit some tendency to get blown over in strong winds/crosswind landings
on the slope. I have had good results with the straight dihedral aileron
equipped Schweizer HLG penetrating in rather strong winds up to about 25
mph. I might suggest you consider examining the trim of your glider before
you dump it in favor of a flying wing or other aircraft. Consider
1) Check the CG to make sure it is at the manufacturers suggested location
(the Schweizer tends to build up mildly tail heavy).
2) Check the decalage (relative angle between the chord line of the wing and
the chord line of the horizontal stab) such that it is approximately 1.5
degrees. Foamy airplanes tend to get tweaked when crashed or carried in a
vehicle and they get knocked out of trim. It is also possible to warp the
EPP fuselages when assembling using strap tape. Check to see the the aft
portion of your fuse lies flat when placed against a flat surface (if not it
is an indicator that the fuse is warped/tweaked and you need to correct the
problem using a monocoat iron/heat gun bending the part in a direction
opposite the warp while applying heat).
When properly adjusted the DAW Schweizer has one of the widest performance
envelopes (light lift to very strong wind conditions) of any EPP foamy
glider. The improvement resulting from getting the decalage set correctly is
significant. If you have too much positive incidence set in the horizontal
stab it will reduce the high end speeds that the glider can operate at.
Schweizer 1-26 gliders built for the slope can benefit from slight reduction
of the decalage to no more than 1.5 degrees as this will preserve the wide
speed range the glider can fly at.
The best flying of the EPP foam flying wings in my opinion is the CSD
Boomerang. This is a rather agile glider designed for combat but is tuff
enough for intermediate flight training. If you decide not to work further
on improving your DAW Schweizer this would be a glider to consider (it flies
in light lift and also fine in quite strong winds).
Best wishes!
