If you've been bashing your small-scale truck hard lately, chances are your 1 16 rc body shell is looking a little worse for wear, with cracks and scratches telling the story of every failed jump. It's the part of the car that takes the most abuse but also the part that gives your rig its personality. Replacing a body shell isn't just about fixing damage; it's about making that mini-monster look exactly the way you want it to.
Whether you're running a Traxxas Mini E-Revo, a Losi Mini-T, or one of those surprisingly fast WLtoys models, the body shell is your canvas. But picking the right one involves more than just finding a cool color. You've got to think about material, aerodynamics, and whether it'll actually fit over your battery and shock towers without a massive headache.
Why the 1/16 Scale is Such a Sweet Spot
There is something uniquely fun about the 1/16 scale. It's small enough to run in a driveway or a local park, but big enough to handle some actual dirt. Because these cars are lighter than their 1/8 scale cousins, they tend to bounce rather than break, but the 1 16 rc body shell still acts as the primary shield for all those expensive electronics tucked inside.
Most hobbyists love this scale because it's portable. You can throw a couple of these in a backpack and head out. However, because the chassis are more compact, the clearance inside the body shell is tight. If you pick a shell that's too low-profile, you might find your cooling fan rubbing against the ceiling of the cab, or your wires getting pinched. It's a balancing act between aesthetics and practical space.
Lexan vs. PVC: Know What You're Buying
When you're browsing for a new 1 16 rc body shell, you'll mostly see two types of plastic: Polycarbonate (often called Lexan) and PVC. If you're serious about the hobby, you really want to stick with Lexan.
Lexan is that clear, flexible stuff that you paint from the inside. It's incredibly durable. You can flex it, crash it, and it usually just pops back into shape. PVC shells, on the other hand, are often what you find on cheaper toy-grade cars or very budget-friendly replacements. They tend to be more brittle. One bad landing in cold weather and a PVC shell can shatter like an eggshell. It's worth spending the extra few bucks for a proper polycarbonate shell if you plan on doing anything more than driving in straight lines on carpet.
The Art of the Custom Paint Job
One of the best things about buying a clear 1 16 rc body shell is that you get to be the designer. Most people go through a bit of a learning curve here. The most important rule? Paint the inside. Since the shell is clear, the plastic itself acts as a built-in clear coat. This protects your paint from getting scratched off every time you roll the car over.
Before you even touch a spray can, you've got to prep the surface. Use a little bit of dish soap and warm water to wash the inside of the shell. Manufacturers often leave a "mold release" oily residue on the plastic, and if you don't wash it off, your paint will flake off in giant chunks after your first run.
Once it's dry, use high-quality masking tape for your windows and any stripes you want. Then, spray in thin layers. Don't try to get full coverage on the first pass, or you'll end up with drips. And remember: start with your darkest colors first and end with your lightest. If you spray white over black, it won't show. If you spray black over white, you'll ruin the white. It sounds backward, but that's the magic of painting from the inside out.
Making it Fit: The Mounting Struggle
Not every 1 16 rc body shell is a perfect "drop-fit." Even if it says it's for your specific model, you might need to do some trimming. This is where a good pair of curved Lexan scissors becomes your best friend. Don't try to use regular kitchen scissors; you'll end up with jagged edges that eventually turn into stress cracks.
You also need to think about the body post holes. Using a body reamer is much better than using a drill bit. A drill bit can catch the plastic and tear it, whereas a reamer creates a clean, circular hole that you can gradually widen until it fits perfectly.
If you're trying to put a body from a different brand on your chassis, you might need to get creative. Sometimes you'll need to swap out the body posts or even use "stealth mounts" (magnets or Velcro) if you want that clean look without pins sticking out of the hood.
Boosting Durability with the "Drywall Tape Trick"
If you're a "basher"—someone who likes to send their RC car off big jumps and see what happens—you know that the front and rear of the shell are the first places to crack. There's an old-school trick to make your 1 16 rc body shell nearly indestructible.
Get some fiberglass drywall mesh tape and a tube of Shoo Goo (or a similar flexible adhesive). Line the inside of the body with the tape, especially around the wheel wells and the body post holes, and then smear a layer of the glue over it. Once it cures, it creates a sort of internal roll cage that's flexible but incredibly strong. It adds a little weight, sure, but for a 1/16 scale basher, the trade-off is totally worth it for a body that lasts all season.
Aerodynamics: Does it Matter?
You might think aerodynamics wouldn't matter on a car that's only a foot long, but at 30 or 40 mph, it really does. A high-downforce 1 16 rc body shell (like a wing-heavy buggy style) will keep the car planted on the ground. However, if you're running a "Short Course Truck" style body, which is basically a big parachute, you might find the car catching air and flipping over backwards at high speeds.
If you do a lot of high-speed speed runs, look for shells with low profiles and smooth lines. If you're racing on a tight indoor track, you might want something with more side-bite to help you corner. It's funny how much the "face" of the car changes how it handles the wind.
Keeping it Clean After a Day in the Dirt
After you've spent a Saturday at the track, your shell is going to be covered in grime. Don't just leave it there. A quick wipe down with a damp cloth keeps the plastic from getting stained and keeps your paint job looking sharp. Avoid using harsh chemicals like brake cleaner or motor spray on the shell, as these can actually cloud the Lexan or melt the paint right off.
If you've got scuffs on the outside, sometimes a little bit of automotive wax or even some furniture polish can bring back that shine. It won't fix deep gouges, but it'll make the "battle scars" look a bit more respectable.
Final Thoughts on Upgrading
At the end of the day, a 1 16 rc body shell is a consumable part. It's meant to be used, abused, and eventually replaced. But that's the fun of it. Every time you get a new shell, it's like getting a brand-new car. You can change the vibe from a vintage muscle car to a modern desert racer in about ten minutes.
So, next time you see a crack spreading across your hood, don't sweat it. Take it as an excuse to try a new color, a new shape, or a new mounting style. Half the joy of the RC hobby is the wrenching and the customizing that happens on the workbench when you aren't out on the pavement. Grab a fresh shell, some paint, and let your imagination run wild. Your rig will thank you for it (by looking awesome while it's flying through the air).
