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

1. 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

2. 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

3. 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 22.2V4000mAh-5000mAh 45c Li-Po battery. If using another battery,

4. the battery must be at least a 22.2V4000mAh-5000mAh 45c battery. Your battery should be approximately the same capacity, dimension and weight as the 22.2V4000mAh-5000mAh 45c Li-Po battery to fit the fuselage without changing the center of gravity significantly.

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 is 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. Move the controls on the transmitter to make sure the aircraft control surface moves correctly. See diagrams right.

Check the C.G. (Center of gravity)

When balancing your model, adjust the battery as necessary so the model is level or slightly nose down. This is the correct balance point for your model. After the first flight, the CG position can be adjusted for your personal preference.

1. The recommended Center of Gravity (CG) location for your model is(110-120mm) from the leading edge of the main wing (as shown) with the battery pack installed. Mark the location of the CG on top of the wing.

2. When balancing your model, support the plane at the marks made on the bottom of the main wing with your fingers or a commercially available balancing stand. This is the correct balance point for your model. Make sure the model is assembled and ready for flight before balancing.

Before flying the model

Find a suitable flying site

Find a flying site clear of buildings, trees, power lines and other obstructions. Until you know how much area will be required and have mastered flying your plane in confined spaces, choose a site which is at least the size of two to three football fields - a flying field specifically for R/C planes is best. Never fly near people - especially children, who can wander unpredictably.

Perform the range check for your plane

As a precaution, an operational ground range test should be performed before the first flight each time you go out. Performing a range test is a good way to detect problems that could cause loss of control such as low batteries, defective or damaged radio components, or radio interference. This usually requires an assistant and should be done at the actual flying site you will be using.

First turn on the transmitter, then install a fully-charged battery into the fuselage. Connect the battery and install the hatch.

Flying course

Take off

While applying power, slowly steer to keep the model straight. The model should accelerate quickly. As the model gains flight speed you will want to climb at a steady and even rate. It will climb out at a nice angle of attack (AOA).

Flying

Always choose a wide-open space for flying your plane. It is ideal for you to fly at a sanctioned flying field. If you are not flying at an approved site always avoid flying near houses, trees, wires and buildings. You should also be careful to avoid flying in areas where there are many people, such as busy parks, schoolyards, or soccer fields. Consult laws and ordinances before choosing a location to fly your aircraft. After takeoff, gain some altitude. Climb to a safe height before trying technical manoeuvres, including high speed passes, inverted flight, loops, and point rolls.

Remember, use care not to bump the throttle stick. Otherwise, the propeller/fan will turn and possibly cause damage or injury.

Note: Please refer to your Transmitter Manual that came with your radio control system to perform a ground range check. If the controls are not working correctly or if anything seems wrong, do not fly the model until you correct the problem. Make certain all the servo wires are securely connected to the receiver and the transmitter batteries have a good connection.

Monitor your flight time

Monitor and limit your flight time using a timer (such as on a wristwatch or in your transmitter if available). When the batteries are getting low you will usually notice a performance drop before the ESC cuts off motor power, so when the plane starts flying slower you should land. Often (but not always) power can be briefly restored after the motor cuts off by holding the throttle stick all the way down for a few seconds. To avoid an unexpected dead-stick landing on your first flight, set your timer to a conservative 4 minutes. When your alarm sounds you should land right away.

Landing

Land the model when you hear the motor pulsing (LVC) or if you notice a reduction in power. If using a transmitter with a timer, set the timer so you have enough flight time to make several landing approaches. The model’s three point landing gear allows the model to land on hard surfaces. Align model directly into the wind and fly down to the ground. Fly the airplane down to the ground using 1/4-1/3 throttle to keep enough energy for proper flare. Before the model touches down, always fully decrease the throttle to avoid damaging the propeller or other components. The key to a great landing is to manage the power and elevator all the way to the ground and set down lightly on the main landing gear. After a few flights you will find the model can be set down lightlyon the mains and you can hold the nose wheel off balancing themodel on the mains until it slows and gently settles the nose.

Maintenance

Repairs to the foam should be made with foam safe adhesives such as hot glue, foam safe CA, and 5min epoxy. When parts are not repairable, see the Spare Parts List for ordering by item number. Always check to make sure all screws on the aircraft are tightened. Pay special attention to make sure the spinner is firmly in place before every flight.

Programmable Items (The option written in bold font is the default setting)

1. Brake Setting：Enabled / Disabled

2. Battery Type：Lipo / NiMH

3. Low Voltage Protection Mode(Cut-Off Mode)： Soft Cut-Off (Gradually reduce the output power) /Cut-Off

(Immediately stop the output power).

4. Low Voltage Protection Threshold(Cut-Off Threshold)：Low / Medium / High

1) For lithium battery, the battery cell number is calculated automatically. Low / medium / high cutoff voltage for each cell is 2.85V/3.15V/3.3V. For example: For a 3S Lipo, when "Medium" cutoff threshold is set, the cut-off voltage will be:3.15*3=9.45V.

2) For NiMH battery, low / medium / high cutoff voltages are 0%/50%/65% of the startup voltage (i.e. the initial voltage of battery pack), and 0% means the low voltage cut-off function is disabled. For example: For a 6 cells NiMH battery, fully charged voltage is 1.44*6=8.64V, when "Medium"cut-off threshold is set, the cut-off voltage

will be: 8.64*50%=4.32V.

5. Startup Mode：Normal /Soft /Super-Soft (300ms / 1.5s / 3s)

a) Normal mode is suitable for fixed-wing aircraft. Soft or Super-soft modes are suitable for helicopters. The initial acceleration of the Soft and Super-Soft modes are slower, it takes 1.5 second for Soft startup or 3 seconds for Super-Soft startup from initial throttle advance to full throttle. If the throttle is completely closed (throttle stick moved to bottom position) and opened again (throttle stick moved to top position) within 3 seconds after the first startup, the re-startup will be temporarily changed to normal mode to get rid of the chance of a crash caused by slow throttle response. This special design is suitable for aerobatic flight when quick throttle response is needed.

6. Timing：Low / Medium / High,( 3.75°/15°/26.25°) Usually, low timing is suitable for most motors. To get higher

speed, High timing value can be chosen.

Begin To Use Your New ESC

IMPORTANT! Because different transmitter has different throttle range, please calibrate throttle range before flying.

Throttle range setting (Throttle range should be reset whenever a new transmitter is being used)

1.Switch on the transmi t ter, move throttle stick to the top position.

2.Connect battery pack to the ESC, and wait for about 2 seconds.

3.The "Beep-Beep-" tone should be emitted, means the top point of throttle range has been confirmed.

4.Move throttle stick to the bottom position, several "beep-" tones should be emitted to present the amount of battery cells.

5.A long "Beep-" tone should be emitted, means the lowest point of throttle range has been correctly confirmed.

Normal startup procedure

1.Move throttle stick to bottom position and then switch on transmitter.

2Connect battery pack to ESC, special tone like "♪ 123" means power supply is OK.

3.Several "beep-" tones should be emitted to present the amount of lithium battery cells.

4.When self-test is finished, a long"beep-----" tone should be emitted.

5.Move throttle stick upwards to go flying.

E N

Protection Function

1. Start up failure protection: If the motor fails to start within 2 seconds of throttle application, the ESC will cut-off the output power. In this case, the throttle stick MUST be moved to the bottom again to restart the motor. (Such a situation happens in the following cases: The connection between ESC and motor is not reliable, the propeller or the motor is blocked, the gearbox is damaged, etc.)

2. Over-heat protection: When the temperature of the ESC is over about 110 Celsius degrees, the ESC will reduce the output power.

3.Throttle signal loss protection: The ESC will reduce the output power if throttle signal is lost for 1 second, further loss for 2 seconds will cause the output to be cut-off completely.

遥控器设置

警告：为保证安全，在遥控器参数设置及舵面调整过程中，请务必拆下螺旋桨，以免电机意外启动发生事故。遥控器发射机开机

前，确保油门杆在最低位置，其它摇杆在中立位置。开发射机并给接收机通电，随后听到电调初始化音（音符释义见后文“电子调

速器说明书”）。观察所有舵面是否回中，如果没有回中，尽量通过调整舵机摇臂角度、连杆长度的方式来使舵面回中，若调整长度

在安全范围内仍未回中，则使用遥控器通道微调或者菜单中的“SubTrim”选项来使舵面归中。如下图所示观察摇杆动作与舵面

动作的对应关系，如发生舵面反向需要使用遥控器中的通道反向功能来纠正。

1.移动发射器上的控制杆位置，确保舵面可以自如移动。

装电池以后）。推荐把食指放在机翼下面的重心位置来帮助调整

重心。

2.在调整飞机重心的时候请确定飞机处于组装完毕待飞的状态。

110-120mm

飞行前准备

起飞前的检查

每次飞行前须做严格的地面检查，可有效避免飞行事故的发生。

1. 检查全机螺丝是否安装到位、舵角摇臂连接可靠。机翼快拆装置已锁紧。

2. 安装电池，并调整飞机重心到说明书推荐位置。

3. 动力电池、遥控器发射机电池等已充满电，处于可靠工作状态。

4. 发射机油门杆保持在最低位（推荐使用带有油门锁定功能的遥控设备），打开发射机，随后连接动力电池，待电调初始化完成后

检查各个舵面是否回中，是否动作正确。

5. 轻推油门观察螺旋桨转向是否正确。

所有检查完成后，方可进行飞行，初学者首次飞行需要有经验的爱好者协助完成，避免因操作不当发生飞行事故。
