Carl Goldberg GBGA1077 - Manual (Page 27)

Place the fully assembled aircraft on a model balancing stand, as shown above. You can make this simple set-
up with a couple of ¼" dowels with rounded 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 equipment 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
doesn't balance the model, add weight to the far end of the nose or tail, respectively, until the model is correctly
balanced. The least weight is needed when added as far back or forward as possible. Fasten the weight per-
manently in place.
TAIL DRAGGER OPTION
NOTE: The tail-dragger option is not recommended
for novice pilots. It is best to get plenty of
practice with a tri-gear before converting
your Tiger 120 ARF into a tail-dragger.
This option might require additional weight
added to the nose of the plane to achieve the
correct CG Balance. The amount of weight
you have to add depends on the weight of
the motor you are using.
The tail wheel option shown is available direct
from Carl Goldberg Products by calling 678-
450-0085 Monday thru Friday 9:00 to 2:00
EST. This package includes all the hard ware
required to turn the Tiger 120 in to a tail drag-
ger version.
