3DR ArduCopter Quad-C
Thank you for purchasing a 3DR ArduCopter Quad kit. The 3DR ArduCopter Quad is a stable
and supported multi-rotor frame in the ongoing development of the ArduCopter codebase on
DIYDrones. It features a very durable Aluminum and G10 FR4 frame that can withstand hard
impacts. The wide legged stand allows for more stable takeoffs and landings and provides an
unobstructed view for a bottom mounted camera. The 3DR ArduCopter Quad is designed by
3D Robotics in San Diego, California and manufactured in 3D Robotics in Tijuana, Baja
California.
Revisions to frame:
Revision B - Adds a removable base for easy access to the PDB and APM mounting slots.
Revision C - Shorter arms. Motor mounting is no longer done with a bolt through the entire arm,
but now the motor just mounts to a single face of the arm. Previous mounting method caused
the arm to sink in. Added blue arms. Reduced frame weight.

Assembly Guide
Solder Motor and ESC Connectors
Note: You may choose to solder the ESCs directly to the PDB. This will save time on this build
and not require you to solder connectors to both the ESCs and the PDB. Soldering connectors
however will allow you to easily remove components in the future.
1. Solder all bullet connectors to the motors and ESC. Male connectors go on the
motors and female on the ESC. Make sure to heat up both the cable and the
connector to avoid a cold solder joint. For a short video demonstrating how to solder
bullet connectors follow this link: https://www.youtube.com/watch?v=aEK2e0xUi5s
2. Slide a piece of shrink tubing over the bullet connectors and apply heat to shrink.
heat can be applied with a soldering iron or a heat gun. Note: Female connectors
should be fully covered by shrink tubing to avoid shorts.
3. Slide two pieces of shrink tubing on the red & black wires on the ESC.
4. Solder male Deans or your preferred connector to the red & black wires on the ESC.
Note: Make sure the black wire is soldered to the negative (-) terminal of the connector and
the red to the positive (+).
5. Pull the shrink tubing over the exposed connector leads and shrink it.
Choosing + or x
Something to keep in mind during this build is which configuration your vehicle will be
flown in. This is later chosen when setting up your APM in the Mission Planner. There is
no effect on performance it is just a matter of personal preference. Both the + (Top)
and X (Bottom) configurations are pictured above. The blue arms indicate the front of
the vehicle. This manual will continue building the vehicle in X configuration. Please
adjust accordingly.
Arm Assembly x4
Note: If assembling a quad kit prior to Revision-C and installing 880kv (orange) motors the
centered hole on the arm that allows room for the shaft to poke through needs to be drilled out
to 10mm.
1. Attach the motor to the arm using two M3x5mm screws (Blue) and two M3 lock
washers (Orange) making sure the screws go into the threaded holes in the motor
and not the ventilation holes. (If the motor is screwed using the ventilation holes, it
will not spin freely) Route the motor cables through the hole on the side of the arm.
2. Use two M3x25mm screws (Green) and two M3 metal nuts (Pink) to fasten the legs
to the arm using the indicated holes. To provide rigidity to the legs attach two
M3x18mm spacers in between the legs and secure with four M3x5mm metal
screws (Blue).
3. Repeat for all 4 arms.
Main Frame Assembly
1. Attach the bottom and top plates to one of the arm assemblies using an M3x30mm
screw (Blue) and an M3x25mm screw (Green), secure with two M3 metal nuts (Pink).
Note the four screws closer to the center of the vehicle are longer than those on the outside.
This 4 longer screws will be used to hold the PDB cap and stack-up assembly.
2. Repeat for the other three arms.
3. Attach four M3x08mm spacers as indicated in the figure above and fasten using four
M3x5mm nylon screws (Red).
4. Slide the velcro straps through the two slots on the bottom plate. The velcro straps
will be used to fasten the flight battery bellow the vehicle.
5. Slide four rubber washers (Orange) onto the M3x30mm screws (Blue) that stick out
of the top plate.
