In part 1 of our Nazgul5 DJI FPV build post we covered all the parts we used to fit the iFlight Nazgul5 frame with the DJI Air Unit and antennas. In this post(part 2) we will cover all the rest of the build, step by step.
The first thing we did after installing the camera and antenna 3D printed mount was to fit the Tekko32 F3 HDV 40A ESC onto the frame. Follow that by soldering in each one of the four motors to it as well as the XT60 battery wires. Now rejoice! Because in this build, that is the last of the soldering.
Now slide the Kakute F7 Flight Controller onto the stack and make sure everything has a little space between the two boards. Connect the ESC to the FC with the provided cable. And at this time also connect one end of the included FC to DJI Air unit cable into the Flight controller. This will make it easier for you to do now before you install the 3D printed Air Unit bay. Tighten the bolts to secure the stack in-place.
Now place the 3D printed Air Unit bay over the four standoffs that surround the stack, and press down until it fits snugly above the stack. At this point you should be looking at something that looks like this next image.
Now we have the ESC/FC stack fitted and bolted, and the 3D printed Air Unit bay stacked on top. In order to secure the Air Unit into the bay we used an exterior 3M double-sided tape in the middle of the bay. It's this that will keep the unit from moving or falling out of the drone during a heavy impact. The top of the Air Unit will be kept in-place by the top of the frame in a couple of steps.
Now strip off the top layer of the 3M tape and position the Air Unit with the camera facing the front of the drone. It's also important here to fit both the SMA antennas into the Air Unit before you stick it all down, but do not connect the cable from the FC just yet. Press the Air Unit securely into the bay.
This is what you should be looking at now.
With everything in the stack now installed it's the perfect time to connect the cable from the FC into the back of the Air Unit. When you have completed that we can move onto fitting the DJI FPV camera into the 3D printed mount.
This next step is pretty easy! But one important thing to note before you install the camera. There is an arrow on top of the DJI FPV camera to show you which way up to fit the camera. Find that arrow and make sure it is facing the top of the camera before you screw the unit into the mount. Also, make sure you tighten any standoffs surrounding the camera to make sure everything is 100% secure.
When that step is done you should have this.
All we have left to do now is to attach the top of the frame onto drone. And then add the GoPro 3D mount to the front. Before you screw the top of the frame on, make sure the battery strap is all hooked up and installed. When you have that complete, attach the frame top and GoPro mount and tighten all the screws. You will now have a fully complete build. Like this.
Attach the long range antennas to the 3D printed mount. Now you are ready to begin the setup in BetaFlight. We may post a BF setup guide in the near future. But for now we just wanted to show you the steps of our build process. We hope it was easy to follow, but if you do have any questions or comments for us please leave them below.
