Meet the X8+
Thank you for purchasing an X8+!
The X8 is a powerful octocopter platform for aerial video.
Review this manual in its entirety before your first flight.
Additional instructions can be found in the X8 information
portal at 3DR.com/X8/info.
Happy flying!

Setup: Assembly
The X8 arrives in travel configuration. Complete
these steps to prepare the X8 for flight.

Remove the bolts and thumbnuts outside the two folded black arms (1).
Unfold the black arms, re-insert the bolts, and secure with the thumbnuts (2).

2 Unfold Legs
Remove the bolts and nuts to the inside of the folded legs (1),
unfold the legs, re-insert the bolts, and secure with the nuts (2).
3 Attach Propellers
The X8 uses SF and SFP propellers. These labels can be found on the
individual propeller packages and on the propellers themselves. See
the diagram below for which motors require SF or SFP propellers. The
accuracy of this assembly is critical for the X8 to fly correctly.
To attach each propeller, remove the nut and washer from the motor,
and add the correct type of propeller with the writing on the propeller facing
the sky. (This will be a tight fit; apply pressure and twist the propeller
onto the motor.) Replace the washer over the propeller, and tighten the
nut on top using the propeller wrench.

Ground Station
A ground station is a laptop or tablet running an ArduPilot-compatible mission control application.
In the field, a ground station helps you monitor the X8 during flight, plan missions, and trouble-
shoot issues. We recommend using a ground station at all times with the X8.
To set up a ground station, choose a platform below and visit 3DR.com/download_software to install
the application.

Important Note About Vehicle Setup in Mission Planner and APM Planner:
Your X8 has been pre-configured at the factory and is ready to fly. Re-performing the
calibrations on the Initial Setup screen, including the mandatory hardware configurations
and setup wizard, can adversely affect the performance of your aircraft.
iOS? There are currently no ground station applications available for iOS.

Power Management
The X8 is powered by a rechargeable lithium polymer (LiPo) battery. When fully
charged, the battery provides up to 15 minutes of flight time depending on payload,
environmental conditions, and flying style. Flying with a gimbal, GoPro, and FPV
system can reduce flight time by up to 5 minutes. Flying aggressively or in high winds
can affect power consumption and reduce flight time. Monitor power consumption
using the flight data display on the controller (press and hold the DN button).
When the battery reaches the low voltage limit, the X8 will initiate a low battery failsafe
and land automatically at the current position. (See page 20 for more information about
failsafes.) To avoid a low battery failsafe, monitor battery voltage during flight on the
controller’s flight data display, and end your flight before the battery reaches the low
voltage limit.
Controller
Press and hold the DN
button to view flight data.
flight battery mAh consumed since armed
Another way to monitor power consumption is by using milliamp-hours (mAh).
Monitor the mAh on the controller, and ensure that it does not exceed 8,000
mAh (80% of the battery’s available capacity). Exceeding 8,000 mAh can
render the battery permanently unusable.
Do not exceed 8,000 mAh for a fully charged X8+ battery.

Full battery: 16.8 V
Low battery limit: 14 V
End your flight at 14.1 V.

Connect the charger to the power adapter cable
and a wall outlet. Connect the red cable to the +
port and the black cable to the - port.

!
Flying with a low battery is a safety
risk and can render the battery
permanently unusable. Always fly
with a fully charged battery.
Charge the battery using a designated
LiPo balance charger only. Always
monitor the battery while charging.
Protect the battery from extreme
heat, extreme cold, puncturing, and
flammable surfaces. Always transport,
charge, and store the battery in the
guard bag.
Inspect the battery for damage before
and after flying. If you observe any
swelling of the package or the battery
ceases to function, do not use the
battery; locate your local battery
recycling center, and dispose of the
battery. In the US and Canada, visit
call2recycle.org to find a location.
Do not dispose of the battery in the
trash.
