There are a number of special RC helicopter tools and supplies that you will need in order to build and maintain your RC helicopter/s.

This write-up is geared more towards larger RC helicopters (bigger than micro size).

Most micro helis (coaxial, FP, CP, & tiny Multi-Rotors) certainly don't require many of the tools that the larger collective pitch and multi rotors do, but hopefully this page will show you some of the basic and not so basic tools needed in this hobby to better prepare you. I have provided links to many of the tools so you can further read up on them and get an idea of costs, or need to order them, etc.

Too Many RC Helicopter Tools

Don't get overwhelmed by looking at all the tools in the above photo. This is the accumulative result of 25 plus years in the hobby. When starting out you will only need a fraction of what's pictured here, but I will go over most items.

Many people do overlook this expense when getting into the hobby only to realize once they get their helicopter kit home, they can’t properly build it. Worse yet, they try to build it without some of these tools and this will almost certainly result in at minimum a very poor flying machine and likely a crashed heli. Even if you get a RTF heli - you will still need many of these tools for repairs and maintenance.

The photo below is a more realistic representation and shows almost every tool you'll need when first starting out.

Basic RC Helicopter Tools

There are must have tools, and nice to have tools – as the years go by, you will slowly accumulate the “nice to haves”.

Many of the tools you may already have kicking around in your work shop or tool box, especially if you are already into some type of RC hobby; but there are a few specific RC helicopter tools that you'll probabally still need to get.

Don’t feel you have to get the very best tools on the market. Over time you will soon find out what tools you use the most and as they wear out, you can then replace them with higher quality tools.

Must Get RC Helicopter Tools

Pitch Gauge

A Helicopter Pitch Gauge is essential to correctly set the pitch angle and range of pitch on your main rotor blades on collective pitch RC helicopters. It is one of the most important RC heli specific tools you absolutely must get if you are getting into collective pitch. You can get basic ones, but I personally really like the digital pitch gauges because they are so easy and fast to use & they work on 250's all the way up to 800 size helis.

Dubro Balancer
Balancing A Propeller With Dubro Balancer

The Dubro Balancer Pictured above & left is an amazing "must have" RC helicopter tool. I have used it for main and tail rotor balancing on all sizes of helis, engine cooling fan balancing, airplane propeller balancing, RC car and truck wheel balancing, and of course Multi/Quad rotor propeller balancing. It offers such great value since it can do so much for under $30.00. There are stand alone rotor blade balancers, but you can't check the whole head or use them for all the other aspects of RC Balancing that the Dubro provides.

Metric Hex Drivers

An assortment of metric Hex/Alan Drivers for the many hex bolts and set screws found on RC helicopters. Most heli kits don't come with Alan keys anymore and if they do, they are usually poor in quality, made of soft metal and round off or strip out very easy. This not only makes the tool useless, it also damages the hex set screw or bolt - very frustrating!

The sizes you use most often on a heli are usually 1.5, 2.0, 2.5, & 3.0 mm. The best advice here is to start with a decent quality basic set with hardened ends like the E-flite set pictured or another inexpensive yet decent quality option is Turnigy's Basic 4 Piece Hex Driver Set.

Metric Socket Drivers

A basic set of metric socket drivers also comes in handy if you don't already have a set of small metric sockets. The sizes most commonly found on RC helicopters (RC in general actually) are 4.0B, 4.5B, 5.5B &  7.0B.

Screw Driver Set

I'm sure most people already have a basic screw driver set such as shown here but I figured I better mention it. On RC helicopters, you mostly find Phillips Heads, but you may come across flat head, and very rarely Torx.

Ball Link Pliers

Ball Link Pliers - Okay I admit I got by for years without this tool. I used needle nose pliers instead. I damaged so many ball links and balls, I spent more money on replacing them than the pliers cost, not to mention the frustration - don't make the same mistake I did. 

Assembly Towel

Assembly Towels for how little they cost (or are even included in some kits) are wonderful things to have. They are not really a tool; but once you've built or worked on a heli with an assembly towel underneath to catch screws, bolts, washers, setscrews, or any other little items that otherwise bounce and roll off the bench or table into the dark abyss below; you'll never want to be without one again.

Swashplate Leveling Tool

Swashplate Leveling Tools - These tools are very important for setting up a 120 degree CCPM swashplate correctly and leveling it. This is even more important these days with flybarless systems as the swash has to be more or less perfectly level when you register that neutral position in the FBL unit. I have an e-book on Swash Setup that shows how to build your own swash tool as well, but these purpose designed tools work the best, easiest to use, and are the most accurate. They come in all sizes for different rotors shaft diameters so I haven't linked to a specific one. Align makes them as well as others. Here is just one example for a 5mm rotor shaft (what most 450 size helicopters use).

Glow Plug Wrench (long reach is nice on RC helicopters) - Only needed for nitro powered birds.

Computerized Battery Charger

If you fly electric powered RC Helicopters, you're going to need a decent computerized charger (sooner rather than later). If you don't know what to look for in a charger, that link above takes you to a full write-up I've done on these things. I also have a writeup on the power supplies that you usually need to power them with.

To save on page download time, the rest of the must have items listed don't show photos since I'm sure most people already know what they look like.

Nice To Have RC Helicopter Tools

Okay, now we get into the stuff you might not need in order to build or maintain your RC helicopter/s, but most of this stuff will make your life easier once you get it; or you may find you do actually really need it as you advance in the hobby. I've listed it more or less in order of importance. The first few top items in fact could almost be consider "must haves" so there is a bit of gray overlap area here between must & nice to have depending on the person and what they fly.

RC Helicopter Soldering Equipment

Big picture for a big tool topic - SOLDERING! If you are into RC and even more so, electric powered RC; soldering equipment is pretty much a must have; but you can fumble by without it for a little while. I basically have two main soldering tools I use all the time. The black box in the background is a combination soldering and SMD rework station. The grey gun looking thing in the foreground is a Weller 100/140 Watt soldering gun. With these two soldering tools, I can do just about anything needed in the hobby from working on fragile SMD and circuit boards, applying the prefect amount of heat on shrink tube to make custom wiring harnesses, to soldering large 8 gauge wiring and connectors. I should probably do an entire write-up on soldering equipment as it's such a neat and fascinating topic (at least I sure think so); but for now I'm just going to make a few soldering tool recommendations.

Weller Hobby Soldering Iron

If you don't want to spend much money, yet still have variable heat control (highly recommended), the little Weller 40W Hobby Soldering Iron here is a decent unit you can find at most hobby shops. It's certainly not powerful enough to solder anything much larger than perhaps 12 gauge wiring, but for smaller stuff or electronic board components, it works fine. Small irons like this do take time to heat up so it's not near instant heat like the better more powerful temp controlled irons, but it still works.

Here is the Weller soldering gun I use - the 120V 100/140W unit. As I said, it's good for big wire soldering and that's pretty much what I use mine for exclusively when soldering large gauge battery pack or ESC wires to connectors, bullets, terminals, etc. Soldering Guns like this heat up fast (about 5 seconds when the trigger is pressed) and with the two position trigger to control the heat output at the tip, you still do get a very rudimentary level of heat control.

Finally, if you really want a top notch soldering tool, you are going to be looking at higher Wattage soldering stations with quality ceramic heating elements that heat the tips up in 15-30 seconds, have precise analog or digital heat temperature control, standardized size replaceable tips, and other "pro" type features. I've had a professional Weller WD1001 digital soldering station for several years now; but I have to tell you, I've been absolutely elated with the Aoyue 968A+ soldering & rework station not to mention it's half of what I paid for my Weller digital stand alone soldering station. I rarely use my Weller station anymore because I like the Aoyue better.

I won't bore you with all the details since you can read about them on the link I provided, but I've had this Aoyue station now for over a year, use it almost daily, and absolutely love it! I didn't think I would use the rework much, but it's a perfect hot air gun for shrink tube work with the precise digital temperature control and variable air flow along with a good assortment of torch tips & soldering tips (usually those have to be purchased separately with more costly stations). I've been breathing in soldering fumes pretty much my whole life, so didn't think I'd turn the smoke extractor on much, now I can't live without it. For $170 bucks - you'll be hard pressed to find a quality solder/rework station that does all the Aoyue 968A+ does. Highly recommended tool!

If you're going to be soldering wires, you are going to need a way to remove the insulation off the tips of the wiring - enter the indispensable wire strippers. There are various types of wire strippers from the "one size fit's all" types to the more common types that accommodate each individual gauge size such as pictured here. I like this style the best myself for the simple reason I find them more precise. No matter what type you choose, you need to get strippers that cover all the sizes of wire you end up working with. For my electrical RC needs, that can be anything from as small as 30 gauge that you see on some tiny servo leads or scale lighting systems, right up to 8 gauge on large electric motors, ESC's, and LiPo packs. I need two sets of strippers to cover that range. The smaller set covers 32 up to 24 gauge, and the larger set covers 22 up to 8 gauge.

Digital Calipers

Digital Calipers or just regular calipers are another tool I feel is almost a must have in this hobby. I use mine all the time for measuring pushrod lengths, shaft diameters, bearing sizes, screw lengths, drill bit diameters, pitch slider centering on the tail shaft, spacer washer thickness, clutch liner thickness, swash height, servo wheel hole distances; just to name a few of the uses off the top of my head. I'm sure I could come up with at least another dozen or so just related to RC helicopters, and another several dozen or so for all the other things I use them for around the shop & house.

Digital Volt Meter

Again, if you are into electric flight, a DVM (Digital Volt Meter) is a handy RC Helicopter tool to have allowing you to measure battery voltages, small current loads, and diagnose opens and shorts in wiring harnesses or circuits. You can certainly spend hundreds of dollars on good DVM's like Fluke; but you don't need anything like that for simple RC. Something like this inexpensive Turnigy one will be fine for most average hobbyists just starting out.

Metric Tap & Die Set

Metric tap-and-die set or at least 3 of the most commonly used sizes such as M3-0.5, M4-0.7, and M5-0.8. I personally feel this could almost be considered a must have tool. Again this is a tool that pays for itself over time.

Electric Hot Melt Glue Gun

You likely already have a hot melt glue gun lying around; but if not, they are good RC helicopter tools and come in very handy for our hobby.

I have used mine for tacking down wiring on board the aircraft, while making my own LiPo battery packs to insulate and secure the main & balance wiring on the connection tabs, making temporary repairs to micro RC helicopters, tacking high stress plug locations so the plug doesn't wiggle loose (moving FPV camera plug for instance), insulating/sealing custom built wiring harnesses, insulating/sealing exposed circuit boards, mounting some electronic control modules on-board the aircraft, etc. 

The great thing with hot melt glue is it sticks well to most things, yet can be fairly easily cut away if you need to remove it or heated back up to soften it. It's also a fast curing glue method. The one thing to be careful with however is the stringy spider web (what I call them) trailers that pull away from the glue gun. These fine glue stringers can and will get tangled in working components if you don't remove them after your glue job. 

Metric Prop Reamer For Multi-Rotor RC Helicopters

A Prop Reamer tool is not needed at all for conventional RC helicopters; but for Multi-Rotor, it's almost a must have RC helicopter tool if you use aftermarket propellers such as APC's MR series, Graupner E Props, etc., so you can correctly size the prop holes to the motor shafts.

You may not need one and be able to get away with prop shaft spacers alone, but there is nothing more frustrating than ordering in a bunch of propellers for your multi-rotor only to find out the hole in them is too small to slide over the motor shaft. This specific one I use is a 4 step metric reamer by Fox Products. The step sizes are 5mm, 6mm, 7mm, & 8mm. I removed the "T" handle that came with it so I can mount the reamer in the chuck of a drill making reaming out the prop hole go so much faster. A reamer is better than a drill bit since it maintains the hole's center point whereas a drill can wonder causing the hole to off-center in the propeller... Vibration city!

Rotary Moto Tool & Accessories

Dremel/similar moto-tool with accessories - after you have and use one, you won’t know how you lived without it. For scale RC helis it's a must have.

RC Helicopter Hardware

An assortment of metric screws, set screws, nuts, washers, ball links and balls. These little guys seem to always fall off the work bench into another dimension, get striped out, wear out, or just need to be replaced from time to time – spares come in very handy.

RC helicopter Ball End Drivers

Ball End Drivers really save the old finger and thumb when you are threading ball links onto the ends of all the pushrods on a RC helicopter build. Once you get a pair of ball end driver RC helicopter tools; you, or more precisely, your fore finger and thumb won't dread threading all those links onto the pushrods ;-)

Head Axle / Feathering Shaft Wrench

A head axle/feather shaft wrench is a great RC helicopter tool to have when one of the blade grip hex bolts is stuck in the head axle shaft. I used to wrap the axle with a few winds of electrical tape and then grip it with vice grips which works fine; but using this tool with the one way bearing to grip the axle is faster and safer for the axle. This particular one fits 4mm, 6mm, 8mm, & 10mm axle/feathering shafts so it's for larger helicopters.

RC Helicopter Optical Tachometer

An optical RC Helicopter Tachometer is something you need to confirm how fast your rotor is spinning. When you are first starting out, you generally don't need one, but it's something that eventually you will likely want to invest in. If your ESC has a RPM data log feature you don't really need one, otherwise - they come in handy. I really like this style I have pitcured because the optical shutter window is nice and big and it covers a wide range of RPM's for both helicotpers, Multi-Rotor Propellers, and Airplane Propellers.

RC Servo Connector Crimp Tool

Here's a RC helicopter tool I really enjoy. A Crimp Tool specifically for RC servo and other small plug connectors. If you want to save a good deal of money by making your own custom servo wiring harnesses or other harnesses that need to have the pins in the plugs crimped onto the small wires - these tools pay for themselves quickly not to mention make a tedious job go quickly. It's another one of those tools that I got along without for years but after getting one, would find very hard to be without.

Dial Indicator

Dial indicator with a magnetic or clamp base is almost essential for fuel powered helis to ensure the fan hub has next to zero runout when mounting it on the engine output shaft. Great for planes as well to see if the motor/engine shaft is bent even the slightest amount after a crash. A dial indicator with 0.001" resolution is adequate I find.

Bench sized drill press with vice. A much more accurate way to drill holes in everything from servo wheels to engine mounts. If you are into fabrication, you'll find a drill press indispensable.

Spare RC Helicopter Parts

Okay, they are not exactly tools; but having replacement RC Helicopter parts on hand for repairs is very convenient when you don't live near a good hobby shop. This is something that just comes with time and experience of what wears out or breaks often on your specific birds. After a while, you'll know what parts to stock but as I've said many times; no matter how well stocked you are, Murphy's Law often prevails and you'll still need a little part you never even considered. In short, don't sweat it and don't try to get every part going. I've actually run into the situation where I have so many parts on hand, I sometime don't realize I have the part I'm looking for and still end up ordering it when it's staring me in the face - DUMB!

Considering that last point... A Small parts bin or organizer to keep all your heli bits organized and easy to find.

Small air compressor with air brush kit and blow gun - these are not only handy for your prize winning custom paint job, but for general cleaning and drying of parts.

Small Hobby Ultrasonic Parts Cleaners are great for cleaning small parts; but I had gotten by without one for years and honestly don't use it much. My wife has basically taken it over for washing her rings and earnings in which it does a great job at I might add.

If you don't like messy hands - blue nitrile surgical gloves

Small Hobby Lathe - since I got one, I have machined my own custom parts for my RC helis and cars. The main thing I find I use the lathe for however, is checking shafts (main, tail, blade grips, engine, fan hubs, clutches, clutch bells – you name it) for run out with a dial indicator. I check every part after a crash and even new parts now on the lathe for run out. No more guessing what might be bent after a crash, or worse bent from the supplier (doesn’t happen often, but I have experience it). If the bend is not bad, I have even been able to straighten some shafts to within ½ thou of an inch run-out, better than most new ones.

Well, hopefully this helps you navigate your way around the "RC Helicopter Tool Topic." Just like I mentioned on the RC Field Box page, over time you'll probably find a few other tools and supplies that come in handy or need for your specific helicopter/s. You can see by all the RC Helicopter tools listed above; RC choppers, just like the real ones require wrench time – that's part of the fun - at least I think so...
