Carbon Cub S2

Battery Selection

• We recommend the E-ite

2200mAh 11.1V 3S 30C

Li-Po (SPMX22003S30).

• If using another battery, the battery must be at least a

2200mAh battery.

• The battery should be approximately the same capacity,

dimensions and weight as the E-ite Li-Po battery to t

in the fuselage without changing the center of gravity a

large amount.

1. Lower the throttle stick to the lowest setting and center

the throttle trim. Power on the transmitter, then wait 5

seconds.

2. Apply a strip of hook tape (A) to the bottom the battery

near the end opposite the battery wires.

3. Turn the latch (B) and open the battery hatch.

4. Install the ight battery as shown. See the Adjusting the

Center of Gravity instructions for more information.

5. Make sure the ight battery is secured using the hook

and loop strap (D).

6. Connect the battery to the ESC. Close the hatch and turn

the aircraft over and place it on its wheels. Keep the

aircraft immobile and away from wind for 5 seconds.

7. Keep the aircraft immobile for 30+ seconds until GPS

lock is established as described in the Flying section.

CAUTION: Always disconnect the Li-Po ight

battery from the aircraft when not ying to avoid

over-discharging the battery. Batteries discharged to

a voltage lower than the lowest approved voltage may

become damaged, resulting in loss of performance and

potential re when batteries are charged.

CAUTION: Always keep hands away from the

propeller. When armed, the motor will turn the

propeller in response to any throttle movement.

Install the Flight Battery

An aircraft with the correct CG has its weight balanced on

the center of the aircraft for safe, stable ight.The aircraft

CG and weight are based on an E-ite 11.1V 2200mAh

30C battery (SPMX22003S30) installed. Make sure the

ight battery is secured using the hook and loop strap.

The CG location is 62-68mm back from the leading edge

of the wing at the root. Balance the aircraft on your nger-

tips near the fuselage under the wings.

• If the nose goes down, move the ight battery back

until the aircraft balances.

• If the nose goes up, move the ight battery forward

until the aircraft balances.

When in intermediate and experienced modes, if the

aircraft CG is too far forward (nose heavy), up elevator is

required to y level at 50%–60% power. If the aircraft CG

is too far aft (tail heavy), down elevator is required to y

level. In Beginner mode the aircraft is not affected. The

SAFE system controls the aircrafts attitude.

Adjust the battery position as needed.
