The Spektrum Ultra Micro FPV camera is a great way of getting a first person view from a small aircraft such as a Hubsan X4. However, with the camera on top, you may want to save on the weight of an additional battery to power it. With a few modifications, we had our new FPV set up and ready to fly. In this blog, we are going to show you how we achieved this.
For this build, we used the Hubsan X4 quadcopter, the Spektrum Ultra Micro FPV Camera and Video Transmitter, and the Flysight Spexman One video goggles for the live view.
The first thing you will need to do is remove the bottom half of the Hubsan shell by unscrewing the three small screws circled in the picture below.
Next, you need to remove the battery connector from the camera and bare the ends of each wire coming from it.
After that has been done, you can go ahead and solder the camera wires to the underside of the main board where the battery is connected; red to red and black to black.
Then you can arrange the camera like so…
…and replace the bottom part of the shell.
Secure the camera to the top of the shell using a double-sided sticky pad.
All that is left to do is put on your video goggles, tune them in, and take it for a test flight.
You’ll have a blast flying this around, especially in places where it would be much harder with a larger model. We’ve certainly had fun testing it in the office; even flying it under tables and out of the window.
