Hey folks!
In posting my experiences with my very first multirotor build, I was surprised by how many questions I got from people who are also just starting out in this hobby. During my attempt to understand multirotor concepts I found so much valuable info all across the Internet, but realized that I often felt uncomfortable asking very basic questions in a sea of experts. There is a vast amount of info out there, based on rapidly advancing technology. While this info is almost always valuable for reference or future use, I found myself needing explanations stripped down to the most basic form. Sometimes I find it easier to learn from folks who are on my own level, instead of asking someone far more experienced to slow down to my pace. I am in the infancy of this hobby, and this is just some info I have gathered along the way…
I am creating this thread with the hopes of sticking to the most basic info, focused on helpful things to know when first starting out with multirotors. I am NO expert, in fact far from it. These are just some of the things I wished I'd known for my first build, and the parts I should have ordered when I initially decided to take the plunge. I did a few things right, and more than a few things wrong. Maybe these lessons can help others who are new to the game. As our collective experience grows, checking back here to drop a hint or tip will likely help those who are right behind us in getting into this obsession...
Before we begin, a quick shout-out to Bart who has made this forum possible, and what it is today... a great place to gather info in a friendly and relaxed atmosphere. Check out the Sticky's at the top of this Beginner's Section. Cheers Bart!
If tricks, tips and hints begin to roll in, I will try to keep this updated towards the top of the thread so it's easy to reference. Let's try to keep it on-topic.
BEFORE YOU BEGIN: Before you do anything, you need to decide what it is you are trying to accomplish with your first build? Is it for stunt flying? Maybe you’d like to do aerial video or photo (AP)? Do you want to get into First Person View (FPV)? These are the questions that need to be answered BEFORE you begin making lists and ordering parts.
BUDGET: Best to be honest with yourself about this up front, because chances are - you will quickly blow past that mark. Everyone wants to pay as little as possible to get airborne, but it’s not always realistic. Set a budget knowing that you may go over by a bit. Comfortable with that number? This hobby can lead to dangerous scenarios if done incorrectly, so it is best not to skimp on certain things. Plan ahead so you know you have enough scratch to build a safe craft.
TINKERING & SKILL LEVEL: Do you have patience? Do you own a good soldering iron? Are you willing to put the time in to tweak a complicated Flight Controller, or do you want plug-n-play? Better to decide these things up front before thinking you'll dive in to your first build using a raw Arduino board and turning your own hardware on a lathe. Most of what you have to do for a basic build is... well, basic. But there are more advanced concepts that take a ton of research and patience to wrap your head around. Know what you're capable of beforehand, and that will help dictate purchases/choices.
DON’T BITE OFF MORE THAN YOU CAN CHEW: We all want a straight shot to the perfect multirotor. But the truth is, it takes some serious research and development to build our ideal craft. Probably best to accept what you know, and what you may be capable of. This way the chance for success, however modest, is well within your reach. Someone with past RC experience will probably have an easier time advancing to the more sophisticated concepts. Those of us that are completely new to the hobby may need to take baby steps. No shame in taking your time to ensure that the first machine you put in the air, regardless of whether it’s tricked-out or simple, is safe and secure – and of course FUN!
GATHER, ACQUIRE, DIGEST: As stated earlier, there is enough multirotor info out there to choke a horse. But that's what it takes to get one of these inanimate objects airborne. Be ready to scour the web, read, and attempt to digest as much as possible. This thread will hopefully fill in some of the most basic gaps, but it takes a lot more than basics to get really good at this hobby. So get to it!
BE FAMILIAR: Although you may be shooting for a simple set-up, it's best to familiarize yourself with all the common terms and acronyms. Bart has been compiling a list HERE. These things will come up at some point or another - and best not to interrupt a train of thought every 30 seconds to go look up another definition.
BASIC TOOLS & SUPPLIES: These are the things that I have found to be: helpful, a cool gadget, or tools that are absolutely necessary.
There will be plenty to add to this thread, but for now this should help get a few of you started down the path to better research and hopefully get you into the air a little quicker…

These things will come up at some point or another - and best not to interrupt a train of thought every 30 seconds to go look up another definition.
BASIC TOOLS & SUPPLIES: These are the things that I have found to be: helpful, a cool gadget, or tools that are absolutely necessary.
- Good Soldering Iron: Cheap ones won't work for larger gauge wire and can lead to headaches even on thinner gauges. If you are getting into this hobby, this is a great place to start. Weller is the standard-bearer, and one that has adjustable temp is ideal. If it’s not adjustable, 25W would be a decent choice.
- Good Solder: I have been using 60/40 mix. It’s working for me. I’ve messed with all sorts of solder. You don’t need to spend a fortune, but this stuff is the heart (or blood) of your machine – make sure it’s decent quality.
- Heat Shrink Wrap: This is absolutely necessary for keeping things safe and isolated after you solder. Two metal connectors touching can be disastrous – so make sure you have this in your toolbox – and don’t forget to prep it BEFORE you solder your connector!
- Heat Gun: You can use a hair dryer to melt the heat shrink (some people use a lighter, it’s NOT recommended) – but a proper heat gun can be easier due to its higher temp. These can be had cheap at places like Harbor Freight, and your lady won’t kill you when it gets screwed up...
- Solder Sucker: If you are new to soldering, you may find yourself needing to remove solder and begin a connection again (see prepping heat shrink above). This makes getting old solder off very easy.
- Workspace: Having a good place to work is very helpful. Imagine dropping a 3mm screw onto a messy floor covered in dog hair. Unappealing? So why not set aside some healthy workspace before you get started?
- Organizing Bins: Anything from tackle boxes to the plastic bins from craft stores will help you keep parts organized and easy to find.
- Hex/Allen Driver: The standard L shaped Allen keys are fine for when you need torque – but this hobby is filled with tiny hardware. Get yourself a cheap screwdriver type (with swappable size tips) and you’ll be much happier.
- Loctite: made by many companies, this is the stuff that will keep the hardware tight when the vibrations of motors/props attempt to spin off at altitude, ruining your day. The blue seems best – since you don’t need the semi-permanent red type making motor swaps and repairs difficult. Also, if you are using nylon hardware, test your Loctite first to make sure it doesn’t degrade it.
- Various Hardware: I have found that having a bunch of hardware on hand has made changes, repairs and modifications much less stressful than having to run to the hardware store every time. This is cheap and easy – and online hobby shops often have stock cheaper than you can get locally. Having both nylon and metal hardware in your toolbox helps.
- Extra Wiring: Having common wires on hand is beneficial for the same reason as the hardware above. Better to have extras than have your good time halted by lack of foresight. Having extra servo leads, battery balance extenders and various gauge electrical wire all come in handy. Usually these can be added to your very first order… don’t worry; you’ll use ‘em.
- Extra Connectors: Your choice of connectors will depend on what comes pre-soldered to your parts, discharge/power of your battery and other variables. Deans, XT-60 and bullet connectors seem to be the most popular choices. Whichever you choose, make sure you buy some extras so that you have them on hand when you need them, especially if you are new to soldering.
- Helping Hands: These are priceless for soldering up the multirotor. They can be bought cheap.
- Zip Ties: I have found that having both large and small sizes have made securing ESCs and wiring very easy. You can get various colors to match your build.
- Anti-Static Mat: These are nice to have on your bench to avoid transferring electric shock to the delicate electronic parts of your multirotor. You can usually find these in places that deal with DIY computer components (Radio Shack, online retailers etc).
- Prop Balancer: There are many out there, but they all help get your props balanced correctly. Do some research and get the best you can afford, these will help make your multirotor a better machine. Period!
- Clear Nail Polish: Use this to balance the props and hubs. Many use tape for the blade, but it's easier to use liquid on the hubs. I've used CA to balance hubs, but polish will come off a lot easier if you overdo it.
- Battery Charger: They come in different shapes and sizes, but you absolutely need one. Do some research and get a decent one – you’ll appreciate it when you don’t have to run out and get another one immediately. Don’t forget the wall charger to go with it – they conveniently don’t include that. Make sure you get one that offers "Balance Charging."
- Digital Scale: You really need to know where your build is headed – weight wise. I was able to buy a cheap kitchen scale that switched between all major units of measurement for under $10.
- Tachometer: Cheap infrared tach guns can be had on eBay for about $15, including the tape used for tracking the speed. Good for testing your motor speed.
- Multimeter: Another great tool that can be purchased cheap. Go for the digital kind, and preferably one that can measure DC current up to 20A or higher. If you are near Harbor Freight, you can get a “disposable” one of these for $3!
- Foam: Next time you’re about to toss some packaging foam, think twice. This stuff can be used to secure, protect and isolate components on your quad. The open-cell type in varying densities will come in handy.
- Hot-Glue Gun: Have to admit this is less appealing the more I use it, other than securing delicate parts to a PCB. It does offer a "temporary" hold for some things that you don't want to use CA (or superglue) on, so it has a value for sure. Make sure you get one that has a fine tip on it.
- CA: Basically this is model/hobby superglue. It comes in various strengths and drying times. Always good t have in your toolbox...
- Double-Sided Tape: This stuff can be priceless when you need a small part to stay put.
- Velcro: The mac-daddy of keeping things in one place.
- Liquid Electrical Tape: This stuff is miraculous! Goes on as a liquid, but dries like electrical tape. Gets into the nooks and crannies...
- Hemostat: These things can help hold parts/wires like the Helping Hands listed above, but are not tied to a base.
There will be plenty to add to this thread, but for now this should help get a few of you started down the path to better research and hopefully get you into the air a little quicker…
