Measure aft of the LE at the wing fuse joint 8.3”, place a piece of 1/2” wide tape on the fuselage. BVM used the back side of the tape to CG for a slight nose down balance.

OPTION: Install a #2 button head screw a 1/4” inward at the aft side of the tape on each side of the fuselage.

 Balance the model fully assembled, with all batteries in and gear down

F-16  1:5 Scale

Center of Gravity

Measure aft of the front/rear fuselage joint 8.5”. Drill a 1/16” hole in the fuselage skin 1/4” 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.

 Balance the model fully assembled, empty fuel tanks, gear down, and a full UAT. With the correct CG, the model should balance level.

To help mark the Center of Gravity position when the wing is in place, you can use two Buttonhead screws on the bottom of fuse at the fuse wing joint. (BVM # 5625)

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.

Use a 1/16" drill bit located 9.5" aft of the L.E. of the wing strake. Drill 1/16" holes in the bottom of both wings.

Elevator Throw
Surface travel measured at the tip should be: DOWN - .5" UP - .6"
Flap Throw
Surface travel measured at the root T.E. should be: TAKE OFF - 1-1/4" LANDING - 2-3/4".

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.
