The RC Crawler Tool Kit: What You Actually Need on Your Bench

Nobody tells you about the tools.

You do your research, you pick your first truck, you buy the battery and charger and maybe a LiPo bag, and then your truck arrives and immediately loses a body clip somewhere in the carpet. You need a set of hex drivers to tighten a screw that worked loose on the trail. You want to swap a wheel and realize you don’t have the right tool.

RC crawlers are mechanically simple compared to what they look like, but they do require some basic tools. The good news is that the list is short, and none of it is expensive. Here’s what’s actually earned permanent bench space in my garage, and what I’d tell a beginner to buy before they’re annoyed by not having it.

The Absolute Essentials

Hex Drivers

If you own an RC crawler, you need hex drivers. Nearly every screw on the truck — motor mounts, suspension links, wheel hex hubs, body posts — requires them. Most kits include a basic L-key style hex wrench, and technically you can get by with those. But you won’t want to. The ergonomics are bad, they slip more easily, and your hand will cramp up during any real disassembly.

What you want is a set of proper hex drivers with comfortable handles — the screwdriver-style kind where you can actually apply torque without wanting to throw the thing across the room. The most common sizes you’ll need for micro and compact crawlers are 1.5mm, 2mm, and 2.5mm. A set that covers those three will handle the majority of what you encounter.

I use a set with a rotating top cap that lets you spin the driver quickly for lower-torque screws and then grip down for the final snug — that small design detail makes a real difference over the course of a full disassembly. Worth the few extra dollars over the cheapest option.

Needle Nose Pliers

Small needle nose pliers are indispensable. You’ll use them for installing and removing body clips, bending links, holding hardware in tight spaces, and eventually recovering small parts that bounce off your workbench at the worst possible moment. A standard set from any hardware store works fine here — you don’t need anything hobby-specific.

Body Clip Pliers

Okay, this one is a quality of life upgrade more than a necessity, but once you have them you’ll wonder how you managed without. Body clip pliers are designed specifically for the tiny spring clips that hold RC bodies to posts. They give you a grip on the clip without bending it or launching it at terminal velocity into a pile of gear on your workbench.

If you’ve installed and removed body clips with your fingernails or regular pliers, you know what I’m talking about. These fix that specific frustration.

A Hobby Knife

A basic hobby knife with fresh blades handles body trimming, cutting zip ties, cleaning up pieces, and a dozen other small tasks. If you ever add an aftermarket body to your rig, a sharp hobby knife is mandatory. Keep spare blades — a dull blade is a frustrating blade.

CA Glue (Super Glue)

Thin CA glue is for gluing tires to rims. On most stock RTR setups the tires are already bonded, but if you change tires you’ll need this. Thin formula wicks into the bead and sets quickly. A small bottle goes a long way. Keep some on hand.

Blue Threadlocker

This one took me a while to start using consistently, and I paid for that delay in stripped screws and loose linkages. A small drop of blue (medium strength) threadlocker on screws that are subject to vibration keeps them where you put them. The key word is blue — blue is medium strength and removable. Red is permanent and you do not want to use red on a crawler unless you are certain you never want to remove that fastener. Ever. Blue only.

A small bottle of blue Loctite is inexpensive and lasts forever. Apply it when you’re doing any kind of mechanical work on the truck — suspension links, motor mounts, wheel hubs — and you’ll have significantly fewer mysterious loose screws after trail days.

Nice to Have, Not Mandatory

A Body Reamer

If you ever need to drill a new hole in a body — for an LED, for a body post that’s in a different position, for a scale accessory — a body reamer makes clean tapered holes in polycarbonate without cracking it. A drill bit will crack the body. A reamer won’t. They’re a couple of dollars and worth having.

Tweezers

Small tweezers for retrieving e-clips, holding shims, and managing tiny hardware in tight spaces. You’ll reach for them more than you expect.

A Parts Tray

Not a tool exactly, but hear me out. A magnetic parts tray (or even just a shallow dish) to hold hardware during disassembly will save you real time and frustration. The number of times I’ve watched a 1.5mm screw bounce off a workbench and vanish into the carpet is more than I care to admit. A tray keeps everything in one place and off the floor.

What I’d Actually Buy First

If you’re just getting started and don’t want to buy everything at once, here’s the honest priority order:

Get the hex drivers first — you’ll need them almost immediately. Add the threadlocker early, before you’ve had a chance to lose your first screw to vibration. Then pick up needle nose pliers and a hobby knife. Everything else can follow as you find you actually need it.

One last note: a good local hobby shop is worth more than any tool. The staff at mine have talked me out of two or three unnecessary purchases and pointed me toward a couple I didn’t know I needed. If you’re not sure what size hex your truck uses or whether a particular tool is worth buying, they can tell you. That’s not something an Amazon search gives you.
