FRAME ASSEMBLY

1 Choose + or x

Your 3DR Quad can be flown in both + (plus) and x (cross) configurations. A plus-configured copter flies with one arm forward, while a cross-configured copter flies with two arms forward. While both configurations provide excellent performance, cross is standard and recommended for new fliers. For plus, use three

black arms and one blue arm when assembling your copter, and remember to specify plus when choosing your frame orientation during software configuration. These instructions will continue assembling a Quad in cross orientation.

2 Attach motors to arms

Each arm of your Quad will have a motor attached to the top of the arm using two 5 mm steel bolts and two metal lock washers. To ensure motors are securely bolted to arms, apply a small amount of threadlock to each bolt before fastening.

Threadlocking compound is an important component to ensure your motors remain firmly attached! For application tips, check out this video: goo.gl/bM3MA.

Position holes in the bottom of the motor over the two small holes on either side of the larger hole in top in the of the arm. Secure with two 5 mm steel bolts (with a metal lock washer on each bolt) by accessing through the two large holes in the bottom of the arm. Thread the motor cables through the arm using the hole in the side of the arm. Repeat for all four arms.

3 Install motor collets

Attach a threaded collet to the top of each motor using the four small screws included with collets. Apply threadlock to each screw before fastening. Repeat for all four motors.

4 Assemble legs

Metal nuts

25 mm bolts

5 mm nylon bolts

Leg assembly

18 mm

spacers

Your Quad has four legs, each comprised of two landing gear pieces. To assemble each leg, align two landing gear pieces and attach through the three bottom holes using three 18 mm spacers and six 5 mm nylon bolts.

For each hole, position spacer between holes, and secure from each side with nylon bolts. Repeat for all four legs.

Attach legs to arms with leg pointing toward motors. Align the two top holes in the leg with the two holes in the center of the arm. Insert two 25 mm bolts and secure with metal nuts.

5 Attach top and bottom plates

The top and bottom plates will form the main frame by attaching to your copter’s arms. Align plates in the orientation show below, and attach two blue arms to one end and two black arms to the other using the four pairs of holes as shown.

Bottom plate Top plate Attach black arms here

Attach blue arms here

Place the arm between the two plates so the two holes in the arm align with the holes in the plates. Insert a bolt into each hole and secure with nuts. For inner holes use 30 mm bolts and metal nuts; for outer holes use 25 mm bolts and metal nuts. Add a rubber washer on top of the nut on the inner holes.

For plus configuration: Attach a blue arm to only the position on the plate marked with an arrow.

Inner holes use:

30 mm bolt + arm + metal nut + rubber washer

Outer holes use:

25 mm bolt + arm + metal nut

Bottom plate

 

Next add the spacers that will hold the power distribution board in place. Using the four holes in the bottom plate shown across, align four 8 mm spacers, and secure from the bottom using four 5 mm nylon bolts.

Slide the battery strap through the two slots in the bottom plate.
