RC EYE One Xtreme
The development of the RC Logger EYE One Xtreme began in January of 2013. The Xtreme is available since early 2014.
Starting from here the RC Logger RC EYE One Xtreme is named EOX.
The EOX consist of a fully modular design. Damaged parts can be replaced individually because of the great number of spare and upgrade parts for the EOX. The EOX is a fun flying quadcopter with semi-auto and manual flip function. Three different flight modes - Beginner, Sport or Expert can be chosen by the pilot. A height- hold and a flip- roll function can be activated.
The EOX is also a beginner platform for aerial photography. Many different cameras and environmentally modules are available.

Available types of the EOX
The EOX is available in two different versions; RtF (= Ready to Fly) and ArF (= About/ Almost ready to Fly).
An unboxing video of the RfF-version.
RtF – Ready to Fly
Ready to Fly package contains everything that the user needs to fly the EOX right out of the box. The delivery includes a RC Logger transmitter. There are two different transmitters orderable, Mode 1 or Mode 2 (price is for both equally). There is no difference of the main product itself, hence the main flight controller with embedded 2.4 GHz receiver and the mechanical design of the EOX are identical in both modes. The only difference between Mode-1 and Mode-2 is the stick configuration of the included transmitter. If you are new to the hobby you should ask an experienced RC pilot in your area what mode she or he would recommend you to use. Generally, if you are new to the hobby, it does not make any difference whether you decide to use Mode-1 or Mode2, however it is always best to choose a mode which is most common in your geographical location.
At the RIGHT side of the remote control is the THROTTLE/ AILERON function. When moving THROTTLE/ AILERON into the FRONT/ BACK the EOX will LIFT UP/ DROP. Moving THROTTLE/ AILERON to the LEFT/ RIGHT the EOX will TURN to the LEFT/ RIGHT. On the left SIDE is the ELEVATOR/ RUDDER function. When moving ELEVATOR/ RUDDER to the RIGHT/ LEFT the EOX will fly to the RIGHT/ LEFT. When moving ELEVATOR/ RUDDER to the FRONT/ BACK the EOX will fly FORWARDS/ BACKWARDS.
At the RIGHT side of the remote control is the AILERON/ ELEVATOR function. When moving the AILERON/ THROTTLE into the FRONT/ BACK the EOX will fly FORWARDS/ BACKWARDS. When moving AILERON/ THROTTLE to the LEFT/RIGHT the EOX will fly to the LEFT/ RIGHT. On the LEFT side of the remote control is the THROTTLE/ RUDDER function. When moving the THROTTLE/ RUDDER to the RIGHT/ LEFT the EOX will TURN to the RIGHT/ LEFT. When moving THROTTLE/ RUDDER to the FRONT/ BACK the EOX will fly LIFT UP/ DROP.
Binding the RtF-transmitter (Mode1 & Mode 2) to the EOX
- Move the transmitter’s throttle stick to zero
- Install the flight battery into the EOX and connect the battery. The status LED should go solid green after a short time.
- Press and hold the BIND BUTTON, located next to the battery tray, until the status LED starts to flash green/red.
- Turn the transmitter on (two beeps) and off again (one beep) with the ON/OFF button.
- Press and hold the ON/OFF BUTTON until you hear a beep sound every three seconds. You are binding now the mode. Release the BUTTON.
- Wait until the status LED flashes in the corresponding color related to the selected flight mode indicating that the binding process has been completed. Additionally, two short beeps are emitted.
The delivery is without transmitter. Mostly for advanced flyers who use their own transmitter. The EOX has two options to fly with your personal transmitter. Flying with the OneLink or flying with the PPM-Receiver. The transmitter needs a minimum of 6 channels to control the EOX.
The RC EYE OneLINK (PC: 89036RC)
The RC Logger OneLINK is a signal converter which attaches to your branded transmitter to control the EOX. The OneLINK can be attached via cable (not included) to transmitters from the most popular brands in the model craft industry. The receiver in the EOX is included in the mainboard. The maximal operating distance is 122 meter. Product Codes for the additional cables:
- Futaba Box Trainer Cable (PC: 89056RC)
- Futaba Round Trainer Cable (PC: 89057RC)
- JR Mono Plug Trainer Cable (PC: 89058RC)
- Micro USB Trigger Port Cable (PC: 89059RC)
Binding to OneLINK
- Turn on the OneLink.
- Connect a charged battery to the EOX. The status LED (9) light up solid green. The LED of the OneLINK slowly flashes red.
- Press and hold the bind Button for three seconds. Wait until the status LED starts flashing red and green. The EOX is now in bind mode.
- Press and hold the middle button on the OneLINK. An audible signal will be emitted. The status LED on the EOX will start flashing (green, orange or red) depending on flight mode.
Radio owners will be able to use their existing transmitter in combination with the EOX's PPM ( Pulse-Position Modulation) + S.Bus receiver. The S.Bus micro receiver fits well between the EOX's front orientation LED and battery tray, while the PPM converter can be positioned in-between the control board and battery compartment.
The transmitter has to be capable of transmitting PPM SUM signal, and a PPM receiver that is capable (Not PWM). The transmitter and receiver need to have:
- A minimum of 6 channels (7 channels are recommend for operate the Camera or Modules)
- Two 3-way-toggle-switches
- One 2-way-toggle-switch
For example the PPM can be ordered with the Futaba R6303SB 3/18- channel S. Bus micro receiver and one PPM to S.Bus converter from Fr SKY, but there are many other receiver suitable for the EOX.
The EOX PPM + S.Bus receiver is fully compatible with all versions of the EOX, including the Mode 1, Mode 2, ArF and OneLINK versions. Further information

Before every flight, check the functional reliability of your model and the transmitter. Watch out for any visible damage e.g. defective plug connectors, damaged cables and wires or damages on the main frame. All moving parts of the model must run smoothly but shouldn’t have any play in their bearings. Before each operation, check the correct and the secure position of the propellers. Ensure sufficient residual capacity of the batteries inserted to the EOX and in the transmitter.
During the flight
Check if a propeller is out of alignment. Put your EOX around two meters away from yourself at a eye level. If one of the propellers appears to be visible twice (tow lines), the tracking must be fixed. Signals during the discharging process of the battery (only for the technical Release Note Firmware Release V31).
Orientation LED indicated Low Voltage (LV) during the flight (blink frequency is approximately 16 Hz). Additionally flight batteries prevent from being discharged below 3.3V / DC. The LV detection overwrites any LED control status and indicates LV detection even if the LED’s are turned off before the flight. This new feature helps to identify damaged batteries and assists in preventing units from falling. If LV is detected, the user must land the unit immediately.
- Furthermore the transmitter has 4 different warning signals, signaling how long the EOX is already flying
- Alarm I: after 4 min 1 x beep (3 sec. pause), 1 x beep (3 sec pause), 1 x beep (3 sec pause), 1 x beep
- Alarm II: after 5 min 2 x beep (3 sec pause), 2 x beep (3 sec pause), 2 x beep (sec pause), 2 x beep
- Alarm III: after 6 min 3 x beep (3 sec pause), 3 x beep (3 sec pause), 3 x beep (3 sec pause), 3 x beep
- Alarm IV: after 7 min 4 x beep (3sec pause, 4 x beep (3 sec pause), 4 x beep (3 sec pause), 4 x beep
The charging condition of the transmitter batteries are inspected every time the transmitter is switched on and also, continuously inspected while the transmitter is operating.
- Turning orientation LED’s on and off
The LED’s can be turned on and off via the transmitter. Turn them on or off before starting the engines.
- Mode 1: Move the ELEVATOR/RUDDER lever (left side) and the THROTTLE/ AILERON (right side) stick diagonally into their right bottom corner.
- Mode 2: Move the AILERON/ ELEVATOR stick (right side) diagonally into the right bottom corner.
The LED’s will turn on/off.
Flying the EOX
- The EOX has many flight options for just about every type of flyer.
Checklist (to do list) before flying
- Safety checks before commissioning?
- Is the battery connected properly?
- Is the transmitter with the EOX binded?
- Flight mode correctly chosen?
- Gyro Calibrated?
Flight modes & changing
- The EOX comes with three flight modes, beginner, sport and expert mode.
- Beginner is a docile flight mode intended for users who are new to fly quadcopters. The control respond is slow and may feel slaggy to advanced flyers. Auto-levelling is possible in this modus, thus if the pilot lets go the aileron and elevator control levers, the EOX will regain a horizontal level position. The beginner mode is not designed for outdoor flying and carrying a camera or a module since the motor power and agility are reduced.
- The Sport mode may flight the most of the EOX users. This mode is more agile and powerful than beginner mode. Auto-leveling is still engaged, so it is still easy to fly. This mode allows users to fly at light or even mild wind conditions. The acro-function allows semi-automatic flips and rolls.
- Expert mode disengages the auto-level and cranks up the responsiveness to the maximum. Banking angels and power output are significantly increased; acceleration sensor is deactivated, allowing fully pilot controlled flipping and rolling. The expert mode has a feel as a 4-channel CCP model helicopter in heading hold mode. Best results can be achieved in PPM configuration. The acro mode, altitude high hold function and auto –levelling are disabled in expert mode.
- Changing the Flightmode
Set throttle back to zero to get sure that the motors won’t start. Put the Battery into the EOX. The status LED will flashes either green, orange or red, depending on the last set flight mode. Press the MODE button in the middle of the transmitter for two times in short sequence to change the flight mode:
- One beep: Beginner mode, LED flashes green;
- Two beeps: Sport mode, LED flashes orange;
- Three beeps: Expert mode, LED flashes red;
It is not possible to change the flight mode while in flight due to the fact that switching flight modes will reset the gyro and the EOX will take whatever position it is in at that moment as the new level, because this could lead to a crash.
Altitude height hold function
Put the EOX in the desired altitude and push the HEIGHT HOLD button (Mode 1 and Mode 2 on the rear, right side). The Status and orientation LED’s will flash continuously and fast. The function is just possible in Sport mode. It is possible to use RUDDER, AILERON and ELEVATOR while the function is enabled. Avoid to using the THROTTLE to much as this will disengage the HEIGHT HOLD function. This implementation is useful for taking tracking photos with the camera.
Flip and roll function
It's just in sport and expert mode possible. To activate the acrobatic flight mode press and hold the ACRO button while in flight (left side on the rear). The status LED will flash continuously and fast. The orientation LED’s blink continuously with the pattern of three times fast – break, three times fast – break. To flip, move the elevator to the maximum direction. You can roll by activating the acrobatic flight mode and move aileron to any maximum direction.
- You FLIP by activating the acrobatic flight mode and move ELEVATOR to any maximum direction.
- You ROLL by activating the acrobatic flight mode and move AILERON to any maximum direction.
- After a crash it’s always necessary to inspect for damages. If there should be defective parts replace them immediately, otherwise it can impact to properly working parts.
To maintain the EOX in perfect condition is through visual inspections after a crash. During a crash motor mounts and motor arms can sometimes roll. This will cause the propeller to be out of alignment with the rest, and can cause problems. In this case check to make sure all screws are securely tightened. Adjust and realign if necessary. Replace parts with worn out or stripped set screws holes. To check if a propeller’s tracking is out of alignment, hover the EOX about two meters away from yourself at eye-level. If one of the propellers appears to be visible, the tracking must be fixed immediately.
Maintenance of the Motor (brushless)
To keep the brushless motors of the EOX in good conditions it is necessary to place a drop of oil on each bearing (Once every 10- 15 flights is enough to insure the longest possible life for the motors). The oil lubricates, displaces moisture and prevents corrosion of the motor.
Replacing the motor
- Remove the canopy
- Record the colors of the wiring of the defective motor attached to the flight controller board by writing or taking a photo. Detach the motor wiring from the flight controller board.
- Remove all screws including the leg of the motor’s boom.
- Remove the boom from the EOX’s body.
- Ensure the lending leg screws are removed to allow easy passage of motor wires.
- Detach the motor with motor holder from the boom. Pull the wiring out of the boom.
- Loose the motor clamp screw on the motor holder and remove the motor.
- Follow the described steps in reserve order to mount a new motor.
If a propeller is damaged, replace immediately. This also appliers if there are any fine tears or grazing in the propeller. Due to the high speed, material parts could come loose if the propellers are damaged. Observe the rotating direction of the respective motor and the choice of the corresponding propellers without fail. If these are incorrectly chosen, the model won’t be able to fly and will act in an erratic way when starting again. The rotating direction is marked on the propellers (L or R). The propeller mark L must be installed on the motors that turn LEFTWARDS (counter clockwise). The propeller marked R must be installed on the motor that turn RICHTWARDS (clockwise). Don’t squeeze the screws to hard. The Propeller in the front are red. The Propeller in the rear are black. The front side of the EOX is where the front LED is. Before your start replacing propellers, be aware of the following facts and study the diagram. Loosen the spinner counter clockwise and remove it. Remove the washer and pull the propeller off the motor shaft. Slide a new propeller (mind the direction: L or R) onto the motor shaft. The propeller only fits in one direction. You may need to turn it slightly to find the correct position. Install the new washer. Replace the spinner and tighten it with moderate force (over tightening leads to damage of the motor shaft).
The EOX consist of a fully modular design. Each part can be replaced individually. There is no need to replace an entire body shell. All required small parts to mount the spare parts are included.

V31 Flight Control Board
Firmware Release V31 because of technical issues to the previous firmware.
- The improvements comprised
- Gyro reset is now possible only while motors are turned off (not armed). In previous firmware versions, user was able to reset while motor are spinning in idle mode. It’s an additional safety improvement.
- Stock transmitter and OneLINK check frame added. Every received rf (radio frequency) signal frame will be checked in addition to the CRC checksum to prevent glitches and false trimming values to prevent flip to one direction to and small throttle jumps due to corrupt rf signal frame reception which was caused from other interference from other rf sources.
- Optimized Auto flip function (ARCO Mode) to recover to stable flight positon fast and consistently.
- Changing of the flight modes from Beginner-to Sport- and Expert-mode is only possible when the throttle stick is at full zero to prevent accidental changing.
- Added a signal filter which additionally filters each channel RC input, to further prevent unintentional roll/ nick and throttle jumps.
- Orientation LED indicated Low Voltage (LV). Additionally flight batteries prevent from being discharged below 3.3V / DC. Even if the LED’s are tuned of before the flight. This feature helps to identify damaged batteries and assist in preventing units from falling.
- Added 270 Ohm SMD resistor to allow MCU (Multipoint Control Unit) to drop its voltage faster after battery has been removed or not connected correctly (removed and reconnected too fast). This modification has been added to address the issue where one side of motors may not start consistently.
The update required for the costumers just a minimum service fee of USD 7.50 and the one way shipping fee to RC Logger service location in Hong Kong. The replacement took place from 25th June until 31st August 214.

Compatible cameras for the EOX
The EOX is able to carry cameras to make aerial photographs and videos. Therefore the aerial kit is suggested to withstand bigger load and more stable flight. The aerial kit includes longer lending legs to allow space for mounting the camera, the mounting platform for attaching the camera on the unit and a bigger battery capacity to support the bigger load, since the camera is attached. The three pin connector port on the firmware is to bind the EOX to a camera. Once connected it's possible to trigger the camera to take videos/photos. The triggering is just possible with a professional transmitter. Therefore is an additional channel needed, at least 7 channels.
