inboard from the wing root.
Install a #2 button head
screw on each side. The root of the fuselage also has the GC location marked
with a pen. This location is very forgiving; there is no need to move it
forward. The second BVM demo plane is set slightly aft per pilot’s choice.

L-39 1:5 Scale
Center Of Gravity
The factory puts an inked
C.G. mark on the fuselage wing fairing. It is better to transfer that
location to the bottom of the fuse fairing. Make a 1/16” hole 5.6” aft of
the wing L.E. at the root on the fuse. Install a small button head screw on
both sides of the fuse.
A helper is necessary to
balance the model with fuel only in the UAT and a half full 16oz. header
tank. Our demo model needed no ballast. Minor adjustments of the ECU battery
location will suffice.

Center Of Gravity
Balance the eBandit with the gear down and the batteries
in place. The balance point is identified on the bottom of the fuselage by
locating the two 1/16" holes drilled by BVM. They should be 8-3/4" aft of
the L.E. at the wing-to-fuse junction. Install 2 small button head screws to
mark the C.G. position. C.G. position is controlled by battery location.
Mark the fuselage flanges accordingly after test flights.
Balance the wings by weighing them individually. Add weight to the light
wing as follows – example – right wing is 1 oz heavier than the left, add 1
oz of lead in the aileron servo pocket of the left wing. Glue the lead in
securely.
