Important ESC and model information

The ESC included with the model has a safe start. If the motor battery is connected to the ESC and the throttle stick is not in 

the low throttle or off position, the motor will not start until the throttle stick is moved to the low throttle or off position. Once the 

throttle stick is moved to the low throttle or off position, the motor will emit a series of beeps. Several beeps with the same tune 

means the ESC has detected the cells of the battery. The count of the beeps equals the cells of the battery. The motor is now 

armed and will start when the throttle is moved.

The motor and ESC come pre-connected and the motor rotation should be correct. If for any reason the motor is rotating in the 

wrong direction, simply reverse two of the three motor wires to change the direction of rotation.

The motor has an optional brake setting. The ESC comes with brake switched off and we recommend that the model be flown 

with the brake off. However, the brake could be accidentally switched on if the motor battery is connected to the ESC while the 

throttle stick is set at full throttle. To switch the brake off, move the throttle stick to full throttle and plug in the motor battery. The 

motor will beep one time. Move the throttle stick to low throttle or the off position. The motor is ready to run and the brake will 

be switched off.

Battery Selection and Installation. We recommend the 11.1V 2200mAh 25C Li-Po battery. If using another battery, the battery 

must be at least a 11.1V 2200mAh 25C battery. Your battery should be approximately the same capacity, dimension and 

weight as the 11.1V 2200mAh 25C Li-Po battery to fit the fuselage without changing the center of gravity significantly.

1.Pull back on the latch, releasing the canopy.

2.Remove the canopy, revealing the battery compartment.

3.Apply hook and loop tape to the battery.

4.Install a fully charged battery into the battery compartment, with 

the battery cables facing aft.

Note: The center of gravity can be adjusted by moving the battery

forward or aft. Having the correct center of gravity is critical to 

achieving proper flight characteristics.

Receiver diagram

Preflight check

The cables from the servo connector board should be connected 

to your receiver in the order shown. Note that the LEDs can be 

powered by any spare channel on the receiver. Tuck the wire 

leads into the recessed cavity towards the rear of the battery 

hatch.
