We will actually prepare these connections on the FC side first, after that we will cut the wires to length and solder back onto the ESC. That way there will be no excess wires. Given the size and weight of Raiju, we minimize excess weight by removing unnecessary connectors and plugs. Therefore cut the servo plugs of those wires. You can discard those plugs Strip both ends of signal and ground wires, tin them 4 B) FLIGHT CONTROLLER (FC) Turn the board upside down, tin the signal and ground pads (1 through 6) on the ESC Headers rails. We will run the wires from underneath the board through the frame Turn the board right side up, tin RC Input pads as shown (power, ground, 1, 3 and 4) 5 Solder signal and ground wires on the board, laying flat. Label them from 1 to 6 so we can identify them later 6 PART 2: INSTALLATION A) MOTORS Install motors using included hardware B) ESC Cut a piece of double-­‐sided tape, enough to cover the ESC and use it to mount the ESC to the underside of the frame. Make sure the power leads face inwards 7 -­‐ Battery + Once the ESCs have been positioned, cut the power and ground leads to length and solder them in daisy chain configuration as shown above. Use the included JST pigtail to connect to battery Tin the motor pads on the ESC. Roll the exposed tips of motor wires in a circle and tin them Solder motor wires onto ESC pads 8 C) FLIGHT CONTROLLER Label signal and ground wires from 1 to 6. Run them through the cutout holes on the frame. Use 2 spacers per bolt to mount the flight controller. It should give enough clearance to mount the VTX and Pololu underneath the FC. Cut the wires to length and solder to respective ESC D) POLOLU 9 Use a piece of ground and power wire from before, tap into motor 2 power and ground pads. Run the wires through the frame. This 12V input will be converted by the Pololu to 5V, which will then be used to power the FC, VTX and Camera Solder the aforementioned wires to VIn and GND on the provided Pololu. Then solder another ground and power wires from VOut and GND on the Pololu onto the closest power and ground pads on the ESC Header rails. This provides 5V input to power the flight controller from 12V of the main power line. Use a small piece of 3M double-­‐sided tape to mount the Pololu underneath the FC 10 PART 3: FPV SYSTEM A) MICRO MINIMOSD Tin the MinimOSD as highlighted above. Use a small piece of 3M double-­‐sided tape to mount the OSD Connect pad 3 and 4 (on the other side of the FC) to RX and TX on the MinimOSD respectively. Power MinimOSD by tapping into the nearest ESC header pads. Connect the Battery monitor port on the FC to the nearest ESC. The FC will monitor battery voltage. By connecting pad 3,4 to Tx and Rx on the MinimOSD, the same information will be display on the OSD. 11 B) CAMERA Cut the camera wires to length (enough to get to the top), usually about half the length, strip all wires and tin the tips. Run them through cutout slots to the top CAMERA Solder the video signal and ground wires to Video In and GND on the MinimOSD. Solder power wire to the nearest 5V on ESC Header pad 12 C) VTX (Please note that some steps are optional depending on your package) Cut the SMA connector off the antenna Strip away about 1cm of the plastic jacket, be careful not to cut into the braided shielding. Remove the cover and twist the shielding into 2 strands. Strip away the dielectric insulator to expose about 2-­‐3mm of the core. Tin the shielding strands and core. 13 Solder the antenna directly onto the VTX: shielding to the 2 large pads, while core to the small one in the middle. Epoxy over the joint for protection. VTX Use the other half of the camera wire, solder them to the VTX following the marking (5V, Ground, Video). Cut the connector off and solder the wires to the MinimOSD (Video out, Ground) and the 5V power of the motor output rails. 14 PART 4: FINAL TOUCHES A) RADIO RECEIVER Cut the servo connector off the provided servo wire, strip both ends and tin them. Solder one end to input pads on the flight controller as shown above. Solder the other end to the PPM output on your radio receiver of choice. ** Make sure your receiver is PPM capable and PPM mode is activated ** Do one final check through all solder joints, make sure everything is connected. Power up the system, check through your goggles to identify the top and bottom sides of the camera. B) CAMERA MOUNTING Camera Cut a few pieces of the 3M tape, each slightly shorter than the previous. Stick them to the topside of the camera like shown above. The more steps you have, the more aggressively the camera is angled. For beginner pilots, we recommend 1 to 2 layers of tape. Use 3 layers for casual flying and 4 to 5 for extreme racing. 15 Mount the camera to the underside of the frame. Check the vision through your goggles, adjust the camera position to your preference. Make sure the camera is never positioned beyond the front 2 arms. Secure the camera to the frame with a piece of heatshrink C) CANOPY MOUNTING Your build is almost complete now. Dry mock up the position of your receiver and VTX to make sure they will fit under the canopy. Make sure your props have enough clearance. Run the receiver antenna through cutout holes to the underside of the frame. Use provided double-­‐sided tape to mount the Rx on top of the FC or the OSD. Connect your flight controller to Cleanflight and flash it with Cleanflight 1.9 (if not already) Configure your flight controller for Hex X configuration. Check motor rotation, swap any 2 wires on the same motor if rotation is wrong. Once everything is done, secure the ESCs and receiver antennas to the arms with heatshrink 16 Mount the canopy to the frame by heatshrinking it to the 2 back arms and to the camera. ** YOUR BUILD IS NOW COMPLETE ** ** PLEASE CHECK OUT OUR CONFIGURATION GUIDE TO SET UP YOUR FLIGHT CONTROLLER ** 17
