BALANCING THE MODEL
IMPORTANT: NEVER NEGLECT THIS STEP WITH
ANY AIRPLANE. If you try to fly a plane with the
balance point behind the recommended range, you
run the risk of having an unstable aircraft and the
strong likelihood of a crash. TAKE THE TIME TO
PROPERLY BALANCE YOUR MODEL!
To determine the Center of Gravity, measure back
on the fuselage from the leading edge of the
wing. The C.G. range for this aircraft is
3” to 3-5/8".
Place the fully assembled aircraft on a model bal-
ancing stand, as shown above. You can make this
simple set-up with a couple of ¼" dowels with round-
ed tops, spaced 5" apart. Alternatively, lift the model
under the wing near the fuse by your finger tips. (You
may wish to get help from a friend if using the latter
method.) Referring to the recommended balance
range for your model, move the position of the plane on
the balance stand until the model is level or the nose
slightly down. If the is tail heavy, shift the R/C equip-
ment away from the heavy end of the model and
recheck until the model will balance within the
acceptable range. If shifting the R/C gear still does-
n't balance the model, add weight to the far end of
the nose or tail, respectively, until the model is cor-
rectly balanced. The least weight is needed when
added as far back or forward as possible. Fasten
the weight permanently in place.
3. Bolt the wing in place using the two 4mm x
25mm bolts and flat washers. The blind nuts
are pre-installed in the fuselage.
4. Connect the strut to the fuselage using one
of the 2mm bolts, don’t tighten all the way.
The blind nut is pre-installed in the fuselage.
4. Connect the other end of the strut to the
wing with another 4mm bolt. The blind nut is
pre-installed in the wing. Repeat for the
other strut and tighten all four bolts.
