Important Notes

R/C helicopters, including the M1, are not toys. R/C helicopters utilize various high-tech products and technologies to provide superior performance. Improper use of this product can result in serious injury or even death. Please read this manual carefully before using and make sure to be conscious of your own personal safety and the safety of others and your environment when operating all OMP HOBBY products. As they have no control how the product has been assembled and operated by the user, the manufacturer and seller assume no liability for the operation or the use of this product. Intended for use only by adults with experience flying remote control helicopters at a legal flying field. After the sale of this product we cannot maintain any control over its operation or usage. We recommend that you obtain the assistance of an experienced pilot before attempting to fly our products for the first time. A local expert is the best way to properly assemble, setup and fly your model for the first time. M1 helicopter requires a certain degree of skill to operate, and is a consumer item. Any damage or dissatisfaction as a result or accidents or user's modifications are not covered by any warrantee and cannot be returned for repair or replacement. Please contact our distributors for free technical consultation and spare parts when you experience problems during operation or maintenance.

Safety Notes

[CAUTION] Fly only in safe areas, away from other people. Do not operate R/C aircraft within the vicinity of homes or crowds of people. R/C aircraft are prone to accidents, failures and crashes due to a variety of reasons including lack of maintenance, pilot error, and radio interference. Pilots are responsible for their actions and damage or injury occurring during the operation or as of a result of R/C aircraft models.

[FORBIDDEN] R/C helicopters fly at high speed, thus posing a certain degree of potential danger. Choose a legal flying field consisting of flat, smooth ground without obstacles. Do not fly near buildings, high voltage lines or trees to ensure the safety of yourself, others and your model. For the first practice choose a legal flying field please and can use a training skid to fly for reducing the damage. Do not fly your model in bad weather, such as rain, strong wind, snow or darkness.

[FORBIDDEN] R/C models are composed of many precision electrical components. It is critical to keep the model and associated equipment away from moisture and other contaminants. The introduction or exposure to water or moisture in any form can cause the model to malfunction resulting in loss of use or a crash. Do not operate or expose to rain or moisture.

[FORBIDDEN] Please use the replacement parts as listed in the manual to ensure safety operation. This product is an R/C hobby model, so do not use for other purpose.

[WARNING] Before turning on your model and transmitter, check to make sure no one else is operating on the same frequency. Frequency interference can cause your model or other models to crash. The guidance provided by an experienced pilot will be invaluable for the assembly, tuning, trimming and actual first flight. (We recommend practicing with a computer-based flight simulator.)

[WARNING] Operate this unit within your ability. Do not fly under tired condition and improper operation may result in danger.

[CAUTION] During the operation of the helicopter, the main rotor and tail rotor will be spinning at a high rate of speed. The blades are capable of inflicting serious bodily injury and damage to property. Be conscious of your actions, and careful to keep your face, eyes, hands, and loose clothing away from the blades. Always fly the model a safe distance from yourself and others, as well as surrounding objects. Never take your eyes off the model or leave it unattended while it is turned on. Immediately turn off the model and transmitter when you have landed model.

[CAUTION] R/C models are made of various forms of plastics. Plastic is very susceptible to damage or deformation due to extreme heat and cold climate. Make sure not to store the model near any source of heat such as an oven, or heater. It is best to store the model indoors, in a climate-controlled, room temperature environment.

Transmitter Controls (RTF)

The transmitter features LED indicators (Red/Blue) for status and flight modes. It supports Mode 2 and Mode 1 control layouts. Key controls include Throttle/Yaw, Pitch/Roll, and switches for flight modes (Attitude Mode/3D Mode, HOLD/Autorotation). The transmitter specification includes dimensions, operating frequency (2.4GHz), transmit power, weight, modulation type (GFSK), spread spectrum mode (FHSS), working voltage (3.7V), remote range (800m), Micro USB charge interface, low voltage alarm, and a 2500 mAh LiPo battery.

Flight Controller Settings

The M1 Flight Controller has several adjustable parameters accessed via a SET button and control sticks. The functions include setting Yaw Rate, Yaw Gain, Pitch Rate, Pitch Agility, Pitch Gain, Aileron Rate, Aileron Agility, Aileron Gain, Servo Mid-Point, and Collective Pitch. Each setting is adjusted by navigating menus with the SET button and using the elevator stick to modify values from 1 to 9. LED indicators show the current setting mode. A reset function returns all settings to factory defaults.

Radio Setup

Radio Set Requirements: A minimum 6-channel transmitter with heli program supporting 3 flight modes (Normal, Idle1, Idle2) and throttle hold is required. An S.BUS compatible micro receiver is also needed. The receiver connects to the M1 flight control unit via its S-BUS port. Ensure correct pin assignment when connecting.

Transmitter Setup: Swashplate type should be H1 (no mixes). Revomix and all other mixes should be inhibited, with subtrims zeroed. Channel assignment typically includes Roll (Aileron) on CH1, Pitch (Elevator) on CH2, Throttle on CH3, Yaw (Rudder) on CH4, and Flight Mode on CH5. CH5 is a 2-position switch: -100% for Attitude Mode and +100% for 3D Mode. CH1-CH4 should be set to +/-100%.

Flight Mode Setting: The manual provides tables for Throttle and Collective Pitch settings for Normal, Idle1, Idle2, and Throttle Hold modes.

Power On Self Test: Place the M1 on the ground before powering on. After self-test, the blue LED should be steady lit.

Servo Neutral Position Adjustment: Disconnect motor power before adjustment. Power on the remote control and aircraft. Access the servo setting mode via the SET button. Use the transmitter sticks (CH1 for aileron, CH2 for elevator, CH4 for rudder) to center the servos. Save settings by holding the SET button.

Pre-flight Check

• Pitch: Tilt the helicopter forward; the swashplate should tilt back to compensate.
• Roll: Tilt the helicopter to the right; the swashplate should tilt left to compensate.
• Collective and Cyclic Control Rates: Check for any binding on the swashplate when moving sticks to maximum deflection. Adjust rate settings if binding occurs.

First Flight

Step 1: Take the helicopter off. [CAUTION] If the swashplate tilts before lifting off, do not manually trim it, as this can cause instability after takeoff. Allow the helicopter's sensors to stabilize.

Step 2: While hovering, observe for oscillations. If forward/aft oscillations occur, land and decrease pitch gyro gain. If left/right oscillations occur, land and decrease roll gyro gain. Repeat until oscillations disappear.

Step 3: If tail drift or delayed yaw response occurs, reset yaw neutral or increase yaw gyro gain. If the tail oscillates, yaw gyro gain is too high; decrease it.

Step 4: In forward flight, if oscillations similar to Step 2 occur, reduce pitch gyro gain. If the helicopter pitches up or responds slowly, increase pitch gyro gain. Repeat for roll gyro gain.
