15 C.G. Position
● With the wing attached to the fuselage, all
parts of the model installed (ready fly) and
installed battery.
200 mm ∼ 220 mm
●
● With the wings level, have an assistant help
you lift the model by the propeller shaft and
the bottom of the fuselage under the tail.
If one wing always drops when you lift the
model, it means that side is heavy. Balance
the model by adding weight to the other
wing tip.
Do not fly before confirming the
correct location of the C.G.
● If the tail drops, the model is "tail heavy" and the battery and/or receiver must
be shifted forward or weight must be added to the nose to balance. If the nose
drops, the model is "nose heavy" and the battery and/or receiver must be shifted
aft or weight must be added to the tail to
balance.
● If you found it necessary to
add any weight, recheck the
C.G. after the ballast weight
has been installed.
