RubiQ's LEDs are malfunctioning
If your LEDs are flashing rapidly, exhibiting rainbow colors or have gone completely white, then Houston, we have a problem — your PCB is malfunctioning.

First, revisit Step 5 of the Configuration Guide. Troubleshooting steps can be found at the bottom of the page.

Educators, if your PCB continues to malfunction, contact us and we’ll help get you back in the air.

I'm attempting to verify motor rotation and the motors won’t spin
Navigate to Step 6 of the Configuration Guide for complete troubleshooting steps.
Motor rotation doesn’t match the diagram
RubiQ’s arms may have been installed incorrectly. Head to Step 6 of the Configuration Guide for complete troubleshooting steps.
The Accelerometer is not calibrated
Head to Step 8 to Calibrate the Accelerometer. Troubleshooting steps can be found at the bottom of the page.
The Compass is not calibrated
You only need to recalibrate the compass if you take RubiQ to a different city, reset her firmware or notice that she is having trouble with the Return to Home Safety feature.

Head to the Pre-Flight Check step to learn how to calibrate RubiQ’s compass.

Pre-arming check does not show that Navigation is safe
At the end of a successful Configuration, the pre-arming checks in the Setup tab will have all categories showing a green check mark except for “Navigation is safe.” This is because RubiQ comes with GPS lock enabled, which means she won’t fly without first connecting to seven satellites, something she can only do while out at the flight field. Once she’s locked onto the satellites, “Navigation is safe” will give you the green light.
What can go wrong while calibrating the ESC's?
Be sure you are dragging the bar to the very top and very bottom of the slider in one move a piece. If you release the bar part of the way down, the ESC’s will be improperly configured.

Airborne:

Have you completed configuration?
Please ensure you have completed all nine steps of configuration guide, along with the pre-flight checks.

RubiQ cannot be armed or fly unless you have fully completed the configuration process.

The drone is not responding to radio controls
Make sure the drone is bound to the radio by flipping the Beeper.

If the beeper beeps, then RubiQ is bound but not Arming.

  • Be sure the master/main radio controller has switches in the correct position for Return to Home, Angle Mode, etc.
  • Verify the channel mapping using Step 3 of the configuration guide.

If the beeper doesn’t beep, then:

  • A.) The drone and radio need to be bound. Head back to Step 1 of the configuration guide.
  • B.) The drone or radio batteries are low or dead. The batteries need to be fully charged prior to flight.
  • C.) The radio switches may not have been configured. Revisit Steps 2-4 of the Configuration Guide and the included troubleshooting steps.
The drone won’t arm
Check the GPS indicator lights.

Since GPS Lock is enabled, Rubi will not arm unless she’s connected to 7 or more satellites and has obtained 3D lock. Because satellite signals are blocked inside, the drone won’t be able to arm until you go outside.

Make sure both Position Hold and Return to Home are deactivated, since either one will prevent RubiQ from arming.

Make sure both the Compass and Accelerometer are calibrated. Connect to the configurator and review the Pre-Arming Checks in the Setup tab.

At the end of a successful Configuration, these pre-arming checks will have all categories showing a green check mark except for “Navigation is safe.”

The goggles are not receiving video feed
Adjust the channel on the goggles. The name of the game is matching frequencies. Use the chart below to determine the position of the VTX dip switches. These dip switches can be found immediately behind the VTX antenna. It is a red box with three white switches.

Make sure the camera is plugged into the PCB. Please note that the black wire (ground/GND) is positioned towards the inside of the RubiQ chassis as shown in the picture below.

Be sure the goggles are connected correctly to the power source and that they are charged. Some versions of Discover Drones come with goggles that use an external battery. Please be sure to check the amount of power in the battery before flight by using the included battery charger. For goggles with an internal battery, you may check the amount of power by turning them on and looking for the battery symbol in the upper right corner of the screen.

Post-Flight:

The drone crashed
CAUTION Disarm the drone before beginning inspection.

Disarm the drone, then perform a post-flight inspection.

  1. Check the LED’s for any warning messages, then disconnect the battery. Inspect the LiPo battery for any serious physical damage, such as punctures or puffiness, which would require replacing the battery.
  2. Remove all props and check for any that are bent, nicked or broken. These will need to be replaced before the next flight.
  3. Check that all exposed wires are intact. If any have been nicked, wrap them with electrical tape and order replacement parts.
  4. With the hex driver, confirm that screws are still firmly attached and tighten any that feel loose.
  5. Inspect RubiQ’s other physical components, including:
    • Arms, PDB, Frame and Camera Mount: Look for cracks or other signs of a hard impact.
    • Camera, VTX Antenna and VTX: make sure the SMA connection to the antenna is still snug, that the VTX is still connected and fully seated and with the props still removed, plug in the battery to make sure the FPV goggles are still receiving video feed from the camera.
    • Motors: with the props still removed, slowly spin the motors using the radio controller or the Master Control in INAV’s Motor tab. Use your hand to gently feel for any free spinning motors. There should be no rough spots or squeals.
  6. Charge the batteries and securely re-attach props and batteries before next flight.

Replacement parts can be purchased from the PCS Edventures website.

The drone flies erratically
Make sure Angle Mode is engaged to ensure self-leveling.

Recalibrate the gyro sensor by setting the drone on a flatter surface and plugging the battery in again.

Check the prop orientation.

Check the motor/ESC orientation in Step 6 of the Configuration Guide.

Check all screws and make sure the hardware is tight on each arm.

Recalibrate the accelerometer using Step 8 of the Configuration Guide.

Check the magnetic declination using Step 9 of the Configuration Guide.

Inspect the motors for nicks or severed wires and replace if needed.

The drone descends in a spiral when it returns to home
“Toilet-bowling” is usually caused by a miscalibrated compass. Run through the compass calibration and check the magnetic declination in the configurator.

Beeps:

3D-Lock
This happy tone will only sound if RubiQ is stationary and has locked onto at least 7 satellites. With 3D-Lock established, RubiQ is ready for flight.

Depending on the conditions, it may take several minutes to achieve 3D-lock.

Beeper
The SF switch on the Taranis controls RubiQ’s beeper function. The beeper function can be used to find RubiQ when she cannot be seen. It’s also a great way to check if RubiQ is bound to the Taranis.

Critical Component Failure
If your inner warning lights flash blue, stop flying immediately. Disarm RubiQ, and unplug the battery.

To narrow down your issue, connect RubiQ to the configurator and review the hardware component bar at the top of the page.

If your GPS icon shows red, the issue will generally resolve itself after the battery has been disconnected. If any of the other icons show red, there is likely an issue with the flight controller.

Educators, if the problem persists after reconnecting the battery, please contact us for further assistance.

Disconnected the Battery While Connected via USB
Disconnect the USB cable from RubiQ. The tone she makes is only a warning that the battery has been disconnected.

ESC Calibration
Calibrating the ESC’s sets the maximum and minimum throttle values. The happy tones let you know that the calibration was successful.

Inactivity
The inactivity alarm is triggered when the drone is connected to power but the RX is not receiving commands. To get the beeping to stop, unplug and replug the battery back into RubiQ.

Lost Connection to Radio
This alarm sounds when RubiQ loses contact with the radio. Turning off the radio before unplugging the battery after a flight will also trigger this alarm — just unplug the battery.

Low Battery
The Low Battery Warning is a steady beep which triggers when the battery voltage drop below 3.5V per cell. The warning LEDs will also blink red. The beeping becomes more intense if the voltage continues to drop.

Listen for the steady beep and look for your warning LEDs to flash red.

Start-up & Gyro Calibration
Three beeps heard immediately after powering up the board mean that the gyroscope calibration has completed successfully. INAV calibrates the gyro automatically upon every power-up. It is important that RubiQ stay still until the three beeps sound, so that gyro calibration isn’t thrown off. If you move the copter significantly during calibration, INAV will detect this, and will automatically restart the calibration once the copter is still again. This will delay the “three beeps” tone. If you move the copter just a little bit, the gyro calibration may be incorrect, and the copter may not fly correctly.

The tone heard at the end of the GPS search indicates 3D Lock has been established.
