Quanum DIY FPV Goggle (In-Depth Review)

With the cheapest models costing no less than $250, conventional FPV goggles have largely been a gadget used only by serious multirotor enthusiasts with deep pockets. Despite the tumbling prices of multirotor accessories in recent years, FPV goggles still remain a costly investment, particularly for those with tight budgets.

So what do you do if you want to dive into the world of FPV flying but are unwilling to fork out the minimum $250 needed for the most affordable pair of goggles around? The answer is simple — get a pair of Quanum DIY FPV goggles which is currently the cheapest way to experience FPV flying without burning a hole in your wallet.

The Quanum DIY FPV goggles (let’s call it Quanum FPV kit for short) is a do-it-yourself kit that comes with all the basic parts you need for a fully functional FPV goggle. All you need to do is add a battery and a 5.8GHz receiver to it and it’s ready to receive video feed from your FPV camera. The kit itself costs $29.99 at Hobby King which makes it nearly 10 times more affordable than the cheapest FPV goggles around.

Take note that to have a fully functioning FPV system you will also need to purchase an FPV camera and a transmitter to be installed on your drone. This is in addition to the battery and FPV receiver for the Quanum kit which are sold separately.

Assembly

Assembling the Quanum FPV kit is pretty straightforward. The kit comes with a molded housing that is separated into two parts. To assemble the kit, the LCD monitor and fresnel lens assembly is placed in between the two housing parts which are then glued together. In my case, I preferred to hold these two parts together using black electrical tape which I found to be more than adequate. I chose electrical tape because it is easier to remove just in case I need to dismantle the housing in the future for modifications.

Prior to assembling the housing, I had to first attach the fresnel lens of my choice to the lens frame. Many have chosen to glue their lenses to the frame but I chose to use adhesive tape. Again, this is done mainly to allow easier removal of the lens in case I need to swap it in the future.

Once the housing, LCD screen and lens assembly had been installed, I proceeded to attach the adjustable side straps. Now these straps are the worst part of the kit. The straps are so poorly made that they hardly do the job of holding the kit onto your head properly. Even before I attached my FPV receiver and battery, the straps could not even hold the kit in place. Adjusting the straps was useless as they tend to slip past the buckles easily which means any amount of adjusting won’t stay. The only solution would be to tie the straps into a knot. Even with this solution, the straps don’t look like they’re durable enough to last beyond a few dozen flights as they’re simply too thin.

With that said, I find the head straps entirely useless and decided to replace them with a silicon strap that I removed from a pair of swimming goggles. The silicon strap provides enough grip on my head and is durable enough to last more than a few dozen outings. Other users have replaced their head straps with paintball goggle straps which cost around $10 to $30. These straps are wider and should be more comfortable than silicon head straps used for swimming goggles.

If you need to reinforce your head straps, the housing can also take in a top strap.

Video Receiver and Battery

To power up the Quanum FPV kit you will need an 11.1V battery which should suit the majority of LCD monitors and video receivers. The supplied LCD monitor can take a voltage of 7 to 13V while the 5.8GHz 8-channel video receiver that I purchased separately for my kit can take 6.5 to 12V. Since the monitor and video receiver both have their own DC power cables and only 1 source of power, I had to solder both DC cables in parallel to allow both devices to share the same 11.1V battery. Alternatively, you can also supply each device with its own smaller 11.1V battery to avoid soldering and modifying your power cables but this will result in a more complicated setup.

With all the necessary components installed, the Quanum FPV kit can be quite a messy bundle with plenty of wires and parts sticking out all over the kit. One way to tidy things up is to trim any excess wires.

Performance

Once the video receiver and battery have been installed, the Quanum FPV kit is ready for action. With its LCD monitor enclosed in the housing, the kit can provide a really immersive FPV experience quite similar to the more expensive FPV goggles out there. The LCD screen is bright and clear enough for you to get a good picture of where your drone is heading. The fresnel lens can also be positioned via a slider in the housing to help you focus the LCD screen properly.

The only issues that I have with this kit is its bulk and messy exterior. Since the housing comes in only 1 size, users with heads that are too large or too small for it are in for an uncomfortable experience. In my case, the housing was clearly too big for me which meant it entirely covered my nose and half of my face if I were to position the screen properly. Moving the housing up to avoid covering my nose entirely meant the screen was sitting too high but still usable.

The complete Quanum FPV kit with all its weight can feel really bulky on your head. However, with a good set of straps installed and properly adjusted the kit should be able to hold itself properly. To make things less uncomfortable for users, Quanum have included a bunch of foam pads which you can stick to the edges of the housing that come into contact with your face. Some users have found these pads inadequate and have chosen to use thicker foam pads of their own.

Conclusion

Once you have gotten used to its messy exterior, bulk and poor ergonomics, the Quanum FPV kit can provide you with some decent FPV experience. At $29.99 (without shipping fees), it is still the most affordable FPV goggle kit out there costing almost 1/10 of the price of the most affordable conventional FPV goggles. Now that’s what you call a real steal.

By adding a battery and an FPV video receiver, the kit can function as a standalone FPV goggle, albeit with a lot of wires and parts sticking out all over the housing. For those who already have their own FPV goggles but want a second goggle for a spectator friend to “fly” along, the Quanum FPV kit is also a very attractive option.

The only issues are its flimsy head straps and a one-size-fits-all housing that may not suit everyone. Apart from that, the Quanum FPV kit stands in a class of its own and gives you the best value for money when it comes to FPV goggles.
