Important ESC and model information

1. 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 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.

2. 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.

3. 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.

4. 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.

The transmitter and model setup

Before getting started, bind your receiver with your transmitter. Please refer to your Transmitter Manual for 

proper operation

CAUTION: To prevent personal injury, DO NOT install the propeller assembly onto the motor shaft while 

testing the control surfaces. DO NOT arm the ESC and do not turn on the transmitter until the Transmitter 

Manual instructs you to do so.

Tips: Make sure all control sticks on your radio are in the neutral position (rudder, elevator, ailerons) and the 

throttle in the OFF position. Make sure both ailerons move up and down (travel) the same amount. This 

model tracks well when the left and right ailerons travel the same amount in response to the control stick.

1. Move the controls on the transmitter to make sure aircraft control surface move correctly. See diagrams 

below.

1. Apply the hook tape to the cable end of the battery (fig14).

2. Slide the battery into the battery hatch with the power supply cable toward the rear end of the plane and the                         

hook tape facing the bottom of the battery hatch. Note: You may need to relocate the battery position to    

achieve the correct CG for your model.
