SpeedyBee V3 Unboxing

I already knew the build quality of the SpeedyBee V3 was going to be excellent at the point of receiving the product and seeing the box/packaging.

I purchased the flight stack (flight controller + ESC) and both came packaged together in a sleek looking black box with some quality protective foam.

The box lid slides off slowly… very much an Apple-esque experience!

The next pleasant surprise comes as you lift the foam from the base of the box. SpeedyBee have made sure that you have every possible cable needed for your build!

In addition to the cables, there is also a package containing the hardware for building the stack as well as a capacitor. There is also a QR code for accessing the manual.

The SpeedyBee V3 features the option of either connectors or solder pads, meaning that those who prefer to avoid soldering need only solder the motor wires, XT60 connector and capacitor.

The included cables come pre-crimped and housed, ready to just plug in.

SpeedyBee have made building quads accessible to many more people.

SpeedyBee have made building quads accessible to many more people. Any company who can open up the hobby to more people in this way are nothing short of a superhero in my eyes!

With that said, soldering has its benefits. Personally I prefer to solder everything where possible as it creates an arguably more secure connection.

Simply trim off the connectors from the included harnesses and use the wires as you prefer.

SpeedyBee V3 Installation & Build

SpeedyBee have really thought about the end user with regards to the build. Whether you have the soldering skills or not, you are going to have what you need to complete your build.

There is a comprehensive range of diagrams available for every type of build, you can check them out on the official page.

I built my medium-long range quad in Turkey whilst travelling, using only my travel toolkit and travel soldering iron.

I took minimal spare parts and had no problem completing my build, as the SpeedyBee V3 had everything that I needed in the box.

First I decided “dry mounted” the stack in order to decide how everything should fit in the TBS Source V frame.

Once I had decided on the layout, I soldered an XT60 pigtail and the capacitor to the ESC board.

I opted not to use the included XT60, instead building my own using a black XT60 and black wire. Just a personal preference… because you know… NoirFPV for a reason, I prefer the black color 🙂

Next, I platted the motor wires so that they looked all girly and beautiful, then I slotted the ESC back on to the stack screws and soldered the motor wires to the ESC.

Once the ESC had been installed, I connected the ESC to flight controller harness and the camera harness to the two connectors on the bottom of the board.

I opted not to solder these as in both cases the harnesses could simply be connected without modification. I then placed the flight controller on the stack and connected it to the ESC.

With the flight controller in place, I soldered all of the +5V, GND and signal cables and connected them as necessary.

Lastly, I placed the TBS Sixty9 Rx/VTx on top to complete the stack and I must say, I was very pleased with how it turned out!

Using the SpeedyBee: Notable Features

So what’s the SpeedyBee V3 like in the real world? How did I find using it over the last three months since I complete this build?


The SpeedyBee V3 runs Betaflight smoothly and the experience is the same as with any Betaflight flight controller, so I won’t go into too much detail there.

There are however some notable features worth mentioning, that you won’t find on competitor products.

The SpeedyBee App

The SpeedyBee app and wireless connectivity is extremely useful with this kind of build, especially for monitoring GPS in the field.

Being able to access the entire range of Betaflight options from a mobile phone is awesome! As there are many additional features on my long range quad, it needed a lot more tweaking.

I have been using the SpeedyBee App to tweak the modes, switching functions around such as rescue mode, the beeper and beep satellites, until it felt comfortable.

If you fly freestyle or you are in to racing, and you are the type of person who likes to obsessively tweak their PIDs and rates, you are also going to love the convenience of the SpeedyBee App for sure!

LiPo Voltage Reading

Another very useful feature unique to the SpeedyBee V3 is the LiPo meter on the side of the flight stack.

When I first discovered this feature, I thought why doesn’t every FC have a feature like this! There are 4 white LEDs on the side of the FC that indicate how much power your LiPo battery has remaining.

Ok, it isn’t going to replace your battery meter that can measure down to millivolts, but it does serve as an extra check to ensure that you don’t accidently begin a flight using a spent pack!

This feature not only could save you from nuking a battery, it could also save your entire quad, especially if you plan to fly some distance or in an area when it would be possible to easily lose the quad.

SpeedyBee V3 Problems

I have talked very positively about the SpeedyBee V3 in this article. At this stage you may be wondering if there is anything bad about this flight stack?

Well, it can be said that nothing is perfect.

SpeedyBee offer a fantastic blackbox feature, whereby you can easily examine the black box data using the mobile app.

The SpeedyBee V3 flight controller has built-in memory for saving black box logs, which appear to Betaflight as an external SD card.

Note that the SpeedyBee V3 does not have an external micro SD card. This in itself is a disadvantage.

I am going to go out on a limb here and upset the anti-soldering advocates. I am firmly on side with the choice to add connectors to the bottom of the PCB to minimise the amount of soldering required.

However if I could make myself “the perfect flight controller,” I would take the SpeedyBee V3, remove all of the ports (so it is solder pad only) and then use the PCB real estate to add a real Micro SD card slot.

However this is not the issue I wish to discuss. The main problem is the SpeedyBee V3 is just not writing logs to the internal SD memory.

I have tried formatting it with no success. Therefore I have yet to be able to test and use any of the black box logging features.

It is worth noting that I am an Apple Mac OS user and therefore may be struggling to correctly format the memory with the tools available in Mac OS.

Plus I have recently learned about a tool that SpeedyBee recommend for formatting the onboard memory. I plan to have another go at getting it to work and will update this article if there are any developments!

With that said, I would still absolutely recommend the SpeedyBee V3.

Should I Buy the SpeedyBee V3 Flight Stack?

The SpeedyBee V3 is a great choice for both beginners and advanced pilots who wish to build their own quad.

It is not completely free of soldering as the motor wires and pigtail must be attached, but the arguably more difficult job of soldering the tiny wires to the FC has been negated by the inclusion of PCB mounted connectors.

This makes the SpeedyBee V3 an ideal choice for novice and advanced builders alike.

The SpeedyBee V3 is packed with features and therefore is priced accordingly, towards the upper end of the range.

This might put some people off, but if you are looking to use the best quality of product in your build, you can’t go wrong with the SpeedyBee V3!
