Instructions Section 3
The following steps will require flexibility. The drone build should not be complete until the Flight Controller has been calibrated and bench tested since some things may need to be adjusted, but calibrating the Flight Controller will require several of these pieces being prepared and in place. Read through NAZA Flight Controller Setup and Configuration before proceeding with build. Motor Test instructions can be found on Page 15 of this manual.
Step 12: Cleaning up internal wires
Disconnect radio receiver, NAZA LED, EXP and GPS antenna. Before adding the top plate and finishing the build, the wires must be zip tied away from anything that could harm them. (Figure 12A) Wires need to be bundled, coiled and zip tied into the center so that they are out of the way of the screw holes and arm collapse grabbers. Clip ends of zip tie to remove excess bulk. (Figure 12B)

Step 13: Connecting upper plate and mounting GPS antenna
  • Remove all screws that you had placed for safe keeping in the upper brass threads.
  • Four red (2cm) uprights with barbell shape will be screwed into four spots on the lower plate, essentially just past the four corners of the NAZA. (Figure 13A & Figure 13B)

  • Four red (2cm) uprights with braided pattern on the outside need to be screwed into the four far corners of the center so that the uprights are on top to add height for other drone components. (Figure 13C & 13D)

  • Mount the GPS antenna mount on the X slots on the back of the upper plate using the 2 screws and nuts that come with the mount. (Figure 13E)

  • The mast needs to be inserted at the elbow (note: might be a little stiff) and then the mast screw and nut must be inserted and tightened in order to maintain connection (note that there is a nutholder on one side). Tighten the mounting screws and nuts with pliers, but do not overtighten the mast screw as this will prevent GPS pivot and prevent mast from folding for storage.
  • The EXP and LED wires needs to be fed through the small square hole behind the flight control hole on the upper plate and plugged into the EXP and LED slots on the NAZA. Plug the GPS antenna into the PMU and keep it out of the way until final steps when it will be attached to the drone. (Figure 13F)

Step 14: Providing Support in the back
Position the single support fin (left) into the upper and lower plate slots and screw one screw into place near the fin at the arm pivot point so that the fin will remain in place. (Figure 14A) If you choose to put the side plates in, now is the time to position them. (Figure 14B) Prior to doing this, thread the battery cable up through either of the two openings in front of the NAZA. (Figure 14C) One or both side plates may be left out if you would prefer access to the internal components of the drone. **Note: 15B shows look without side panels.

Step 15: Finalizing attachment of the upper plate and very top plate
Screw upper plate down into the red barbell uprights using roundhead T8 hexhead screws. (Figure 15A) Then screw in remaining screws to connect top plate, getting all screws in before tightening any of the screws.

Step 16: Mounting LED
Using an adhesive pad trimmed to size, mount the LED at the elbow of the GPS mount so that the wire is pointing towards the front. This placement will allow the LED to be visible in the rear of the aircraft.

Step 17: Mounting the radio receiver
Screw in the small top plate using round hexheads. (Figure 17A) Plug the radio receiver into GROUND, VCC and SBUS pins and then mount the radio receiver on the left side of the upper plate using an adhesive pad. Thread the antenna wires through the vertical fin at the back and attempt to position on wire going across the back and the other heading towards the front to improve reception. Ensure that antenna wires will not get in the way of the propellers.
