Micro FPV Quadcopter Build
What you will need to get started:
1) Indructrix Quad
2) 150Ah Battery (included in Indructrix set)
3) 600TVL FPV cam (Quanum ELITE 25mW, 5.8 GHz, 40CH Camera.
4) Screw Driver
5) Soldering Iron
6) 60/40 Rosin Core Solder
7) FPV video goggles (Fatshark, Skyzone, Eachine...)
Overview: What's inside?
The Inductrix Quadcopter comes with four motors and propellers, ducted plastic frame, and an onboard circuit board that incorporated both the flight controller and radio receiver.
To get a little technical with it's design, the radio receiver is a linear dipole antenna, which is perfect for a simple radio TX/RX design but prone to noise.
Power cable soldering
Unscrewing the onboard circuit board from the quadcopter and take a look at the power cables coming out of the board. In this quad, the white cable connects the positive lead and the black cable connects the negative lead. To better fit of the FPV camera wires, I like to first detach the power cables from the bottom place and soldering them back on the top of the circuit board.
Fitting the FPV camera cable
The Quanum ELITE FPV camera that we will be using comes with it's own power cable and attachments. For this build, first place the camera on the quadcopter frame and measure how much cable you'll need before meeting the power pins on the circuit board. Give a little slack, extra few mm toward where you think a perfect fit on the quad would be, and cut the ends of the power cable.
Soldering and cable fitting
This is where your soldering skills will be put to the test. If you haven't already soldered the quadcopter power cable on to the circuit board, apply a little solder on the board and solder the power cable onto the top of the circuit board (top is where an arrow can be found is facing on the circuit board). Then flip the board, keeping in mind where the power leads positive and negative ends are, solder the camera cable to the board. Fit the whole circuit board back on the frame. At this point, your camera cables would fit snuggly between the frame and the circuit board.
With everything sitting perfectly together, make sure all the cable are not crushed or caught between the edges of the frame or circuit board. Screw back the screw provided by the quadcopter and your microFPV is 80% done.
There are many ways to fit the FPV camera on the frame itself, what I find that gives the best fit is by supergluing the camera to the frame. Settling camera on the front end of the quadcopter give it's user two advantages: clear and full view of the camera when immersed in FPV, and two, a front heavy build give a instant forward trust upon lift-off.
The quadcopter frame itself has a battery holder that fit most battery, but for third party batteries some brand could prove too snug or hard to even fit in without breaking the frame. What I would do as an optional extra, is find a reusable zip tie like the one shown in the picture and use that instead. This will require cutting the battery holder plastic! This is not a necessary step, but to anyone who would like to improve the flight time and fit a bigger battery to the quad I highly recommend it.
Now that you have completed built your own micro FPV, get out there and bring it out for a test flight you legends! Cheers :)
