It is extremely important to mount the Li-Po battery pack securely in your model, while also achieving the
proper center of gravity.
15.1 Place a section of Adhesive Backed Hook and Loop Tape (EFL2135) on the battery mounting plate
and battery pack. We recommend using the “hook” material on the mounting plate, and the “loop”
(fuzzy) material on the battery pack.
15.2 Mount the battery pack on the mounting plate and install the canopy. Lift the helicopter by the
flybar with the flybar positioned perpendicular to the tail boom. The model is balanced correctly if it
is in a level position in relation to the ground.
If, however, the nose or tail are at a slight downward angle, adjust the position of the battery pack
on the mounting plate forward or rearward as required (with the canopy removed) and repeat the
center of gravity check (with the canopy installed). Continue the battery position adjustments and
CG checks until the model holds a level position when balanced on the flybar.
