These micro multicopters are made with 3D printed ABS plastic parts. The arms are capable of bending without fracturing under a heavy impact, yet they are rigid under a normal load. These attributes are perfect for a micro multicopter frame. The primary required components (not included) are as follows:
KK2 Flight Controller or similar (45mm hole spacing)
A complete frame requires four arms and two frame plates.
It is recommended that the frame be assembled using medium-thick CA glue with CA accelerator. Begin by applying CA glue to the underside of the top plate and accelerator to the top side of the arm’s mounting surface. Press the arm into place and hold the joint until the glue has set.
Repeat this process for all four arms.
Add CA glue to the topside of the bottom plate and accelerator to the bottom of each arm post, then press and hold the upper assembly and arms into place on the lower frame plate. Insure that the arms rest level to the frame.
Now the frame is ready to be wired.
1) Apply accelerator to the inside of each motor mount and a small amount of thick CA glue to the outer surface of the motor shaft (away from moving parts). Press fit each motor into place before wiring the remaining electronics.
2) Solder the 6A ESCs to each of the motor leads. Be sure to pay attention to the proper rotation of each motor and the respective wiring.
3) Complete the power distribution harness with a battery connector.
4) Mount the flight controller with M3 bolts, nylon standoffs, cable ties or double sided tape. Consult your flight controller’s documentation for proper wiring of the radio receiver and ESC signal cables.
5) Secure all loose wires and components to the frame using small cable ties.
