Computing best decalage for desired speed and trim is actually fairly
involved. I know of no one good reliable simple formula that you can use to
calculate decalage (angular difference between wing and horizontal stab) for
all sizes and types of soaring gliders. If you pressed many designers
FM radios modulate the base carrier in frequency (slightly increasing and
decreasing the frequency of the carrier) to transmit information to
receivers and servos. The polarity of the shifting of the carrier is
different for different manufacturers. It would be nice to use one
transmitter
I would be grateful to know of a source for fiberglass mold surface coat
(sometimes a special hard epoxy is applied to the surface of a fiberglass
mold to improve wear and durability). There is one product listed in
"Aircraft Spruce and Specialty Company" catalog but I am uncertain if it is
Discussion in rec.models.rc.soaring usenet group reveals that enthusiastic
local Liftdistribution software "experts" do not understand (at least in a
satisfying intuitive way) why the "Local Cl" graph tends to peak up when
local chord become narrow and decrease when local chord become large
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
There are some really fine experienced designers (which I will not mention
for fear of leaving someone out) that tend to lurk in RCSE and the F3F
mailing list. My hope is that a few of them will join this discussion and
offer nice suggestions. I will offer the following two wing designs in an
