More Throw
Move the linkages in the direction shown by the
arrows to increase the throw of that surface.
Move the linkages in the opposite direction to
decrease the throws. Always configure the
linkages toward the outside of the horns when
possible. This will tend to reduce the amount of
slop that adds up.
NOTE: Throws are measured at the widest
part of the elevators, rudder, and ailerons.
ELEVATOR: NORMAL ....1/2" UP 1/2" DOWN
(High Rate) 5/8" up

(Low Rate) 3/8" up

RUDDER: NORMAL ... .7/8" RT 7/8" LFT

AILERONS: NORMAL ... .9/16" UP 3/8" DOWN

(Low Rate) 3/8" up
1/4" down
NOTE: "Dual Rates" is a feature on some
radios which allows you to switch the control
surface throws in flight. This allows you to
change the responsiveness of your aircraft de-
pending on what maneuvers you are doing. If
your radio does not have "dual rates", then set
up the control surfaces to move at the NORMAL
throws. The SIERRA can be safely flown with
any of the control surface throws listed above.
The higher throws just offer a little quicker
response.
APPLY TRIM
The main pictures show a Sierra covered in Mono-
Kote yellow, red, and orange. Another attractive
option, as shown on the side panel, is covered in
MonoKote jet white, pearl red, and pearl copper.
NOTE: This section gives an overview of how we
often trim our models. Some of the techniques
may seem slightly advanced for beginners, but
they are not really difficult.
NOTE: We use standard MonoKote for almost all
of the trim on our models. "Trim sheets" are not
completely fuel proof, and over time they will
begin to peel up. MonoKote is very thin and
lightweight. When ironed on, it wilt almost never
come off. MonoKote has the added advantage of
being able to go over compound curves since it
is applied with heat.
1. Patterns are provided in dashed lines on the
plan sheets. You may wish to trace these so you do
not destroy the plans. Only one pattern is required
to make the left and right trim pieces using the
technique described here.
NOTE: The better the quality of the cutting board
you use, the better your results will be.
2. The model is first covered completely in its
base color.
3. Choose a piece of trim to start with... for
instance, the forward stripe on the stab. Securely
tape an oversized piece of normal MonoKote,
backing side down, to your cutting board. Tape
another piece of MonoKote, backing side up, on top
of the first piece (this one will be for the opposite side
of the stab).
4. Cut the pattern from the plan sheet, leaving a
healthy border around the lines where possible.
5. Tape the pattern over the MonoKote-covered
cutting board (an alternative is to use a spray glue
such as 3M-77 to hold the pattern to the MonoKote
backing).
6. Always use a very sharp knife and enough
pressure to cut through all of the layers of covering
in one stroke.
7. Use a straightedge to cut all of the straight
lines first.
8. Next, free hand cut all of the curved sections.
snags or mismatches.
10. Use the dashed lines on the plans to locate
the trim on the aircraft. Apply the trim in the same
way as normal MonoKote, but reduce the tempera-
ture some to reduce the occurrence of air bubbles.
11. Repeat this process for all of the trim.
9. Separate the trim pieces and clean up any
