Here is a list of essential FPV tools and materials for building and repairing FPV drones. I will make recommendations what products you might also want to get that are useful for troubleshooting and building.

Getting the “essential tools” listed in this post should be adequate to get you started with building and repairing a quadcopter. However it would be nice to have some of the “good-to-have tools“ too, but by no mean they are necessary.

Essential Tools

These are the recommended and must-have tools for building and repairing your mini quad.

FPV Toolkit

Toolkits that are designed specifically for FPV pilots come with a great selection of useful tools. It’s super handy as you don’t need to go out and search for each item, and usually this is cheaper. They might not be the best quality, but certainly enough to get your started.

For $50, the NewBeeDrone FPV tool kit offers an almost complete set of tools plus a full soldering suite.

• NBD: https://oscarliang.com/product-90hb
• GetFPV: https://oscarliang.com/product-b0z3

It’s hard to beat the value of the RDQ kit though for only $20. It’s a lot less expensive yet still very versatile with a great selection of tools that are adequate for most pilots.

Soldering Tools

Choosing a good soldering iron and solder tin will take a whole blog post to explain. And there are other related tools you might want to get too which make soldering easier and the soldering quality better.

I recommend getting the TS100 soldering iron:

• GetFPV: https://oscarliang.com/product-09on
• RDQ: https://bit.ly/2rswh7A
• Banggood: https://oscarliang.com/product-zxdx

As for solder, I’d recommend:

• Kester 63/37: https://amzn.to/32hj3Oc
• MG Chemical 63/37: https://amzn.to/3h2x5XR

And you also want to get some solder paste (flux):

• Kester Flux pen for general soldering: https://amzn.to/2tLWZbT
• Flux in a syringe for precise applications: http://amzn.to/2zo0WVC
• Solder Paste in a can: http://amzn.to/2sttBJj

Soldering Helping Hands

Soldering requires at least 4 hands – one to hold the iron, one for the solder and two others to hold the components. That’s why you want to get some “soldering helping hands” if hiring an assistant is too expensive.

• With Magnifier: https://oscarliang.com/product-yv00
• Cheapest worth having: https://amzn.to/3vkw3Ol
• 6-arm soldering station: https://oscarliang.com/realacc-third-hand-6-arms-soldering-station/

Mounting putty (even cheaper): https://amzn.to/3xexEqJ

Hex Screw Driver Set

We mostly use hex screws in this hobby, so getting a set of hex screwdrivers is extremely important. The most common sizes you will need are:

• 1.5mm
• 2.0mm
• 2.5 mm

Here are some good options:

• Neewer Titanium – http://amzn.to/2yE1l6c
• Wiha Hex Driver Set – http://amzn.to/2rKsYdo

---

Wire Cutters

I use wire cutters for cutting zip ties, electrical wires etc. When I am being lazy I’d use it to strip wires too before soldering, not the best practice but it works.

• Banggood: https://oscarliang.com/product-nxwd
• Amazon: https://oscarliang.com/product-1kg5

---

Pliers

For gripping components while working with other tools (for example when soldering a wire to an XT60 or ESC power, the wire might become too hot to hold by hand). It can also be used as a nut wrench.

• Banggood: https://oscarliang.com/product-xy0t
• Amazon: http://amzn.to/2rZdzpv

---

Prop Nut Wrench

We commonly use 5mm nylon lock nuts to secure propellers on motors, it’s not an easy job to tighten and undo them without proper tools.

My favourite is probably the Spedix one-way bearing wrench: https://oscarliang.com/product-sdun

---

Multimeter

A digital multimeter (DDM) can be used to troubleshoot your quad’s electronics, verifying voltage outputs, short circuit etc.

I have a whole tutorial explaining how to use a digital multimeter on an FPV drone. Some good DDM purchase options are:

• BSIDE ADM08A: http://bit.ly/2rDzPRL (recommended, feature-rich and good value)
• INNOVA 3320: https://amzn.to/2QkwGss (cheap and basic)

---

Smoke Stopper

A “smoke stopper” is a testing device that you connect between the FPV drone and LiPo battery. You use it when you plug in the battery for the first time to see if the drone has a short circuit, which could potentially damage your components without a smoke stopper.

I recommend the Vifly ShortSafer V2 (review), it works and you can buy it off the shelf:

• RDQ – https://oscarliang.com/product-kb4z
• Banggood – https://oscarliang.com/product-07vv
• GetFPV – https://oscarliang.com/product-58bj
• Amazon – https://amzn.to/3em3itG

---

LiPo Voltage Checker

By simply connecting the balance lead of a LiPo battery to a LiPo checker, it tells you the voltage of the battery, as well as the voltage of each cell. It’s an important tool to have to monitor the state of your LiPo batteries on the go.

• Banggood: http://bit.ly/2k2Y5hE

Good-to-have Tools

Your FPV friends will surely be impressed by these tools :)

Electric Screwdriver

Not necessary but a godsend if you have to do a bunch of 20mm, 30mm long screws often. Simply press a button and the screwdriver will do the rest for you. They also come with a wide selection of screwdriver bits, which could save you from buying those screwdrivers separately.

I recommend the ES126, it’s quite powerful and good quality.

Bench Power Supply

A bench power supply (PSU) has variable voltage output that can power many things, including your TS100 soldering iron, test your quad, FPV components, LiPo charger and so on.

My favorite at the moment is the ToolkitRC P200. It’s versatile and compact.

Tweezers

Tweezers are used to hold and move small components. cross-lock tweezers are preferred because they apply pressure when you release them, they won’t let go of your work even if you set them down.

Wire Strippers

I have one but I rarely use it (mostly due to laziness), I just use my cutters or scissors to strip wires most of the times. But wire strippers provide more consistent and precise results if you are a perfectionist.

• Amazon: https://amzn.to/3etRuFS
• Banggood: https://oscarliang.com/product-czlr

---

Heat Gun

Heat gun, or hot-air gun, is mainly used to shrink heat-shrink insulation tubes. Yes, you can just use a lighter, but heat guns provide more consistent heat and don’t leave burn marks.

• Banggood: https://oscarliang.com/product-boft
• Amazon: https://amzn.to/3sGDXzK

---

File Set

You’ll use these files to modify and clean up things like carbon fiber frame parts, giving them a nice and smooth finish.

Digital Caliper

Useful for precise measurement up to 0.1mm.

• Banggood: https://oscarliang.com/product-qeqb
• Amazon: https://amzn.to/3njPOCW

---

Digital Scale

Every gram counts for RC models that fly, so having an accurate tool to weigh your quadcopter and components is important. Having 1g precision is good enough generally, but 0.1g is even better. Make sure maximum capacity is over 1kg, if you plan to build larger models you might want to choose one with even higher weight limit.

• Banggood: https://oscarliang.com/product-e2zh
• Amazon: https://amzn.to/32HZbmj

---

Clamp Meter

A clamp meter allows you to measure current instantaneously by clamping the jaws around a wire without the need to break into the circuit to take measurements. It’s capable of measuring higher current than a multimeter, but the accuracy might be lower and they are fairly expensive.

• Banggood: https://oscarliang.com/product-tsjy
• Amazon: https://amzn.to/3xlzBBB

---

Kapton Tape

Kapton tape is basically non-stretchy translucent electrical tape. It can withstand high temperature and won’t melt easily, therefore is great for covering PCB when soldering, and wrapping components when you don’t have the right sized clear heatshrink.

Amazon: https://amzn.to/3sGtu7u

---

Watt Meter

A watt meter can measure current drawn and power consumption. It’s useful for testing motor or even measuring the power of a whole quadcopter.

• Banggood: https://oscarliang.com/product-r4b6
• Amazon: https://amzn.to/3esxJyn

---

Motor Thrust Testing Stand

You will need a motor thrust stand for testing motors, propellers and ESC. You can measure thrust, current draw (power), RPM etc.

• Low end: https://oscarliang.com/product-xg4x

Soldering Fume Extractor

Solder fumes are very bad for your lung. Some people can become sensitized to flux fumes, especially from the older rosin flux used in cored solder, and get breathing problems.

• Banggood: https://oscarliang.com/product-w7ni
• Amazon: https://amzn.to/3dMHZ5r

---

RF Power Meter

For testing and measuring radio/video transmitter output power. ImmersionRC Power Meter V2 is an compact and affordable option.

---

FTDI Adapter

FTDI adapter, aka serial converter, can be useful for programming ESC, OSD, FC etc. In the events of damaged USB port on your FC, you can also use it to connect your FC to your computer via one of the UART.

• Banggood: https://oscarliang.com/product-b6ls
• Amazon: https://amzn.to/3tMgNtf

---

Propeller Balancer

A nice addition if you fly 7″ or larger quadcopters, those big propellers might need balancing for the best possible performance. Mini quad propellers such as 5″/6″ and smaller don’t normally require prop balancing.

Supplies and Materials

Electrical Tape

Electrical tape is generally a must-have whenever working with electrical stuff. It’s great for insulation and holding parts in place in your FPV drone build. I also use it for masking when I am soldering.

I only use 3M Super 35, it’s stretchy vinyl and pretty flexible, great for wrapping motor wires or ESC on the drone arms too.

Amazon: https://amzn.to/3ngQNn5

---

Double-sided Tape

Double sided tape is for sticking components inside the build.

• Thin, less strong double sided tape, easy to remove: https://amzn.to/3sH4QDP
