If you've ever spent fifty bucks on a flimsy plastic jump only to have your basher smash it into a dozen pieces on the first landing, it's probably time to build a diy rc ramp that can actually handle the abuse. There is something incredibly satisfying about launching a truck off a piece of engineering you put together yourself in the garage. Plus, when you build it yourself, you get to decide exactly how much "air" you're looking for. Whether you want a long, low jump for distance or a steep kicker for backflips, going the DIY route is the way to go.
Why Building Beats Buying
Let's be honest, the store-bought ramps are often way too small for anything bigger than a 1/16 scale buggy. If you're running a 1/10 scale Slash or a massive 1/8 scale Kraton, those little plastic skate ramps just don't cut it. They slide around, they crack, and they usually aren't wide enough to hit reliably at high speeds.
Building your own diy rc ramp lets you customize the transition. You can make it as wide as you need so you don't have to be a professional marksman just to hit the jump. Also, it's usually way cheaper. You can often find enough scrap wood in your backyard or a neighbor's "free" pile to put together something decent without spending a dime at the hardware store.
Picking the Right Materials
You don't need a degree in carpentry to get this right, but you do need to pick materials that won't fall apart after three jumps.
The Frame
For the internal structure, 2x4s are the gold standard because they are heavy and tough, but they can make the ramp a literal back-breaker to move around. If you want something a bit more portable, 1x3s or even thick PVC pipe can work for the framing. Just remember that the heavier the ramp is, the less it will slide when your five-pound RC car hits it at thirty miles per hour.
The Surface
This is where most people get stuck. You need something flexible enough to bend into a curve but strong enough not to sag. - Plywood: 1/4 inch plywood is usually the sweet spot. It's flexible enough to take a curve if you soak it a bit or just force it down with enough screws. - Masonite (Hardboard): This stuff is super smooth and bends easily, but it hates water. If you leave a Masonite ramp out in the rain once, it'll turn into a soggy waffle. - Corrugated Plastic: Some people use old "For Sale" signs or Coroplast. It's waterproof and light, but it can be a bit slippery for the tires.
Designing the Perfect Curve
The "shape" of your diy rc ramp determines what kind of flight your car is going to have. There are basically two schools of thought here: the flat bank and the curved kicker.
A flat ramp is basically just a wedge. It's easy to build, but the landings can be a bit harsh because the car doesn't get that "pop" at the end. A curved ramp, or a "kicker," uses a radius to compress the suspension as the car travels up, which then snaps the car into the air.
If you're looking for big air and flips, go for a radius. A good rule of thumb is to use a string and a pencil to draw a large circle on your side panels. A 4-foot to 6-foot radius usually creates a smooth enough transition that won't break your shock towers but still sends the car skyward.
The Step-by-Step Build
Once you've got your wood, it's time to get to work. Don't overthink it—it's just a jump.
- Cut the Side Profiles: These are the most important parts. Draw your curve on two matching pieces of plywood. Cut them out with a jigsaw. If they aren't identical, your ramp will be wonky, and your car will corkscrew in mid-air.
- Add the Cross Braces: Cut your 2x4s or 1x3s to the width you want the ramp to be. Usually, 24 to 30 inches is plenty wide for most bashers. Screw these braces between your two side profiles every 6 to 8 inches along the curve.
- Attach the Surface: Lay your thin plywood or Masonite over the top. Start at the bottom (the "toe" of the ramp) and screw it into the first brace. Slowly bend the wood over the curve, adding screws into each brace as you go.
- The Entry Transition: If your ramp has a "lip" at the bottom where it meets the ground, your car will hit it like a brick wall. You can sand the edge of the wood down to a point, or better yet, screw a thin strip of sheet metal or even an old license plate to the bottom so the car transitions smoothly from the grass to the ramp.
Making It Last
Since a diy rc ramp usually lives outside or in a dusty garage, you should probably give it a little love so it doesn't rot. A quick coat of cheap outdoor paint goes a long way.
If you find that your tires are spinning on the smooth wood, you can mix a little bit of sand into the paint. This creates a "grip tape" effect that helps the tires hook up as you're pinning the throttle. Alternatively, some people use old roofing shingles, though that makes the ramp heavy and can be a bit abrasive if you ever have to carry it against your side.
Portability Tweaks
Unless you have a permanent track in your backyard, you're probably going to want to move this thing. Adding a simple handle—literally just a piece of rope or a cheap metal kitchen drawer pull—to the side makes a huge difference.
If you went big and built a monster ramp, consider bolting some cheap lawnmower wheels to one side. That way, you can just tip it up and roll it like a piece of luggage. Your lower back will thank you later.
Safety and Landing Zones
We're talking about toy cars, but a five-pound hunk of metal and plastic flying through the air at head-height is no joke. Always make sure your landing zone is clear.
If you really want to level up your game, don't just build a jump; build a landing ramp too. A landing ramp should be longer and slightly wider than the jump, with a much shallower angle. Landing on a downslope is way easier on your RC car's suspension than flat-landing on concrete. Your chassis and your wallet will definitely appreciate the reduced repair bills.
Go Bash It
The best part about a diy rc ramp is that if you break it, you know exactly how to fix it. If you decide it's not steep enough, you can just unscrew the sides and cut a new profile. It's a project that evolves with your driving skills.
So, grab some scrap wood, find your drill, and start building. Once you see your truck sailing six feet in the air off something you built with your own two hands, you'll never go back to those overpriced plastic store jumps again. Just remember to film the first jump—either it'll be an epic success or a hilarious "fail" video, and both are worth having.
