NOTE: This section is VERY important and must not be
omitted! A model that is not properly balanced will be
unstable and possibly unflyable.
1. The balance point (Center of Gravity) is 3-1/4” (82mm)
from the Leading edge. This is the balance point at which
your model should balance for your first flights. Later, you
may wish to shift the balance up to 1/2”(13mm) behind this
point to change the flying characteristics. Moving the CG
forward will add stability but it will decrease the overall
performance of the sailplane. Moving the balance back
makes the model more agile with a lighter and snappier
“feel” and improves the sailplane’s response to air currents.
However, it will also make the model less stable and can
cause the sailplane to “tuck under” or dive when its flying
speed increases.
2. With the wing attached to the fuse, and all parts of the
model installed (ready to fly), lift the model by picking it up
with your fingertips. If the tail drops when you lift, the model
is “tail heavy” and you must add weight to the nose to
balance. If the nose drops, it is “nose heavy” and you must
add weight to the tail to balance. The model should hang with
a slight nose down attitude. Add BB’s or lead to the nose.
1. The tow hook should be in the front hole for the first
flights. After the first flights the tow hook can be moved back
to the middle hole for most flying conditions. For contest
flying you may want to try the rear hole as it can help
achieve a higher launch. But be careful as the sailplane will
be less stable and more apt to “Pop Off’ the line.
If you are not thoroughly familiar with the operation of R/C
models, ask an experienced modeler to check to see you
have the radio installed correctly and all the control surfaces
do what they are supposed to.
TRIMMING FLIGHTS
It is a good idea to do a couple of trim flights before each
flying session to make sure the plane is still in trim and the
radio is working properly.
Hold the SPIRIT ELITE under the wing with the nose
pointed slightly down and directly into the wind. Launch the
model with the wings level and the nose pointing at a spot
on the ground about 50 feet in front of you. If the sailplane
is launched with the nose up or launched too hard it will
climb a few feet, stall and fall nose first straight down. With
the nose pointed down slightly the sailplane will accelerate
down until it picks up enough flying speed, then level off and
glide forward. Adjust the trims on your transmitter to get the
plane to fly straight ahead in a smooth glide path.
