Get your model ready to fly
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 7.4V 1300mAh 20C Li-Po battery. If using another battery, the battery must be at least a 7.4V 1300mAh 20C battery. Your battery should be approximately the same capacity, dimension and weight as the 7.4V 1300mAh 20C 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.
Control throws
The suggested control throw setting for the 1280mm Easy trainer V2 are as follows (dual rate setting):
| High Rate | Low Rate | |
| Elevator | 20mm up / down | 16mm up / down |
| Aileron | 18mm up / down | 14mm up / down |
| Rudder | 24mm left / right | 20mm left / right |
Tips: On the first flight, fly the model in low rate. The first time you use high rates, be sure to fly at low to medium speeds. High rate, as listed, is only for EXTREME maneuvering.
Clevis installation
- Pull the tube from the clevis to the linkage.
- Carefully spread the clevis, then insert the clevis pin into the desired hole in the control horn.
- Move the tube to hold the clevis on the control horn.
Control horn and servo arm settings
The table shows the factory settings for the control horns and servo arms. Fly the aircraft at the factory settings before making changes.After flying, you may choose to adjust the linkage positions for the desired control response.
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.
- The recommended Center of Gravity (CG) location for your model is(65-75mm) 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.
- 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.
Per form 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.
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.
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 maneuvers, including high speed passes, inverted flight, loops, and point rolls.
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 light Lyon the mains and you can hold the nose wheel off balancing the model 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.

Specifications
Programmable Items (The option written in bold font is the default setting)
- Brake Setting: Enabled / Disabled
- Battery Type: Lipo / NiMH
- Low Voltage Protection Mode(Cut-Off Mode): Soft Cut-Off (Gradually reduce the output power) /Cut-Off (Immediately stop the output power).
- Low Voltage Protection Threshold(Cut-Off Threshold): Low / Medium / High1) 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
- 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.
- 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)
- Switch on the transmitter, move throttle stick to the top position.
- Connect battery pack to the ESC, and wait for about 2 seconds.
- The “Beep-Beep-” tone should be emitted, means the top point of throttle range has been confirmed.
- Move throttle stick to the bottom position, several “beep-” tones should be emitted to present the amount of battery cells.
- A long “Beep-” tone should be emitted, means the lowest point of throttle range has been correctly confirmed.
Normal startup procedure
- Move throttle stick to bottom position and then switch on transmitter.
- Connect battery pack to ESC, special tone like ” 123″ means power supply is OK.
- Several “beep-” tones should be emitted to present the amount of lithium battery cells.
- When self-test is finished, a long “beep—–” tone should be emitted.
- Move throttle stick upwards to go flying.
Protection Function
- 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.)
- Over-heat protection: When the temperature of the ESC is over about 110 Celsius degrees, the ESC will reduce the output power.
- 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.
Trouble Shooting
| Trouble | Possible Reason | Action |
| After power on, motor does not work, no sound is emitted | After power on, motor does not work, no sound is emitted | Check the power connection. Replace the connector. |
| After power on, motor does not work, such an alert tone is emitted:“beep-beep-, beep-beep-,beep-beep-” (Every “beep-beep-” has a time interval of about 1 second) | Input voltage is abnormal, too high or too low | Check the voltage of battery pack |
| After power on, motor does not work, such an alert tone is emitted:“beep-, beep-, beep- “(Every “beep-” has a time interval of about 2 seconds) | Throttle signal is irregular | Check the receiver and transmitter Check the cable of throttle channel |
| After power on, motor does not work, such an alert tone is emitted:“beep-, beep-, beep-” (Every “beep-” has a time interval of about 0.25 second) | The throttle stick is not in the bottom (lowest) position | Move the throttle stick to bottom position |
| After power on, motor does not work, a special tone ” ♪56712″ is emitted after 2 beep tone (beep-beep-) | Direction of the throttle channel is reversed, so the ESC has entered the program mode | Set the direction of throttle channel correctly |
| The motor runs in the opposite direction | The connection between ESC and the motor need to be changed | Swap any two wire connections between ESC and motor |
Program the ESC with your transmitter (4 Steps)
Note: Please make sure the throttle curve is set to 0 when the throttle stick is at bottom position and 100% for the top position.
NO.1 Enter program mode
- Switch on transmitter, move throttle stick to top position, connect the battery pack to ESC
- Wait for 2 seconds, the motor should emit special tone like “beep-beep-“
- Wait for another 5 seconds, special tone like “56712” should be emitted, which means program mode is entered
NO.2 Select programmable items
After entering program mode, you will hear 8 tones in a loop with the following sequence. If you move the throttle stick to bottom within 3 seconds after one kind of tones, this item will be selected.
