In this section, you will conduct some final testing of your ELEV-8 v3 Quadcopter to ensure it is functioning properly and then install the propeller adapters and (finally) the propellers.
BEFORE continuing, please be sure that you have read the entirety of the UAV Safety, Laws, and Good Citizenship [1] guide; it contains very important information to keep you, your ELEV-8, and the public safe and legal. DO NOT SKIP THIS!
The owner, operator, and pilot of every ELEV-8 v3 are to abide by all laws, regulations, and guidelines, including, but not limited to, those detailed in the UAV Safety, Laws, and Good Citizenship [1] guide. Reading and abiding by the entire UAV Safety, Laws, and Good Citizenship [1] document could help prevent property damage, personal injury, prosecution, and fines.
At the end of the Step 30, you will be you will be directed to the How to Fly a Multirotor sUAV tutorial, where you will learn to fly your ELEV-8 v3. DO NOT attempt to fly your ELEV-8 v3 until you have read through both this and the UAV Safety, Laws, and Good Citizenship [1] tutorials, as you may put yourself and others needlessly at risk.
This section will take approximately 15 minutes to 45 minutes, depending on your skill level and equipment.
Before installing the propellers, you need to perform a radio control system range check, which will ensure that your transmitter and receiver are working properly. This step is often overlooked, but failing to perform this check can be have significant, and often dangerous, consequences.
(if you have a Spektrum DXe transmitter, skip this step)
You should have full control of your ELEV-8 from this distance. If you are unable to arm/disarm your ELEV-8 v3 as described below, do not fly! Some component of your system is malfunctioning and you should begin troubleshooting.
At Parallax, we are very often asked about the range of the RC Equipment we use. Unfortunately, there is no simple answer, as most Radio Control manufacturers (including Spektrum, which we use with the ELEV-8 v3) do not publish any information on operating ranges for their equipment, and Parallax cannot accept the liability associated with providing any such information ourselves. However, we can provide some basic guidelines. The operating range of RC equipment can vary widely, and is dependent on many factors, including (but not limited to) weather, receiver mounting position and orientation, transmitter orientation, aircraft size and materials, obstructions between or near transmitter and receiver, ambient radio traffic, transmitter and receiver condition, power, and sensitivity, and finally, distance between transmitter and receiver. With all of these variables, it's important to read and follow all instructions provided by the manufacturers of RC equipment to avoid signal loss. Generally speaking "Parkflyer" type RC Equipment (such as the Spektrum DXe and DX6 Transmitters with AR610 Receiver) is only intended to be used on small aircraft flying at low speeds no more than a few hundred (300-500) feet line of sight from the operator (though they may work at greater distances). More high-end RC equipment (such as the Spektrum DX7 and DX8 Transmitters with AR8000 Receiver) may have far greater ranges, possibly well beyond your line of sight.
WARNING FOR SPEKTRUM DXE USERS: For ELEV-8 Flight Controller firmware versions prior to v1.1, switching the disarm swtich will NOT actually disarm the quadcopter, but just temporarily stop the motors. Use the Ground Station software to view the version number of the ELEV-8 Flight Controller firmware.
Only arm your ELEV-8 v3 when it is safe to do so. When the ELEV-8 v3 is armed, the propellers spin at low throttle - but they can still cause injury even at their lowest speed.
The ELEV-8 v3 currently has two flight modes, Stability and Manual. These modes determine the flight characteristics of the ELEV-8 v3. Manual Mode gives full control of the sUAV to the operator. Stability Mode helps the operator fly steadily by smoothing and limiting the operator’s input.
When the ELEV-8 v3 is unarmed, the RGB LED on the flight controller will be green. There is also a different color that flashes to indicate the flight mode (gear). The LED's flash color pattern indicates the ELEV-8 v3's Status and Mode:
Disarmed (Stability Mode - Green with Blue Blink):
Disarmed (Manual Mode - Green with Orange Blink):
To arm the ELEV-8 v3, make sure that the Gear Switch is in the correct mode, and then push and hold the transmitter sticks down and to the center:
The RGB LED on the flight controller will turn yellow: After 1 second, the flight controller will beep, the RGB LED will turn red with a mode color blink, and the propellers will spin at low throttle:
Armed (Stability Mode - Red with Blue Blink):
Armed (Manual Mode - Red with Orange Blink):
To disarm the ELEV-8 v3, push and hold the transmitter sticks down and away from the center:
The RGB LED on the flight controller will turn yellow. After 0.5 seconds, the flight controller will beep, the RGB LED will turn green with a mode color blink, and the propellers will stop spinning.
Brushless motors sometimes experience a phenomenon known as slip. When a motor slips, it spins slower and in the wrong direction. If this occurs disarm and re-arm, and confirm the issue has been fixed. If you skip this and quickly throttle up, you may not notice the issue until your quad just lifts off the ground and instantly flips.
The Propeller adapters allow you to easily attach and remove the Propellers, and ensure that they stay centered on the Motors.
STOP!! Propeller blades can cut skin. Do not install propellers until you are ready to fly in a properly prepared indoor [5]OR outdoor [6] flying area. Never install propeller blades on a quadcopter in a classroom or a bench testing area. Never connect the flight controller to a computer if the propeller blades are installed.
Attaching the Propellers in the wrong positions is the #1 most common mistake, so follow the directions below carefully!
WARNING: Do not install the propellers until you have gone through every step of the Assembly Guide.
Congratulations on completing the assembly of your ELEV-8 v3 Quadcopter! We know you are probably anxious to fly it, so please head over to the How to Fly a Multirotor sUAV [7] tutorial, where you will learn how to fly your ELEV-8 v3. PLEASE DO NOT attempt to fly your ELEV-8 v3 until you have read through both the How to Fly a Multirotor sUAV [7] and UAV Safety, Laws, and Good Citizenship [1] tutorials, as you could put yourself and others needlessly at risk. (For example, the Flying Guide contains important information on how to identify and switch between flight modes).
