Attach a threaded collet to the top of each motor using the 

four small screws provided with collets. Apply threadlock to 

each screw before fastening. Repeat for all four motors.

Attach top and bottom plates

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 one 

position on the plate.

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 

threaded spacers, and secure from the bottom using four 5 mm nylon 

bolts.

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

The top and bottom plates will form the main frame by attaching to your copter’s arms. 

Align plates as shown below, and attach two blue arms to one end and two black arms to 

the other using the four pairs of holes as shown.

Assemble legs

Leg assembly

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 

two bottom pairs of holes using two 18 mm 

threaded spacers and four 5 mm steel bolts.

For each hole, position spacer between holes, 

and secure from each side with steel 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.
