You have spent hours dialing in your RC truck’s suspension, but the flat pavement just isn’t cutting it anymore. Nothing beats the thrill of catching air, but finding the perfect ramp is often harder than the actual driving.
Learning how to make a jump for rc car projects is a rite of passage for every enthusiast. Whether you are running a high-speed basher or a rock crawler, a custom-built launch pad changes your entire backyard terrain.
In this guide, we will break down exactly how to construct a durable, adjustable ramp that handles heavy landings. Let’s get your rig airborne safely and consistently.
Planning Your Build and Gathering Materials
Before you start cutting wood, you need to decide on the size of your jump. A small, steep kicker is great for backflips, while a long, low-angle ramp is better for high-speed distance jumps.
Most DIYers find that a plywood construction offers the best balance of strength and portability. You will need a few basic tools to get the job done right.
- 3/8-inch or 1/2-inch exterior-grade plywood for the ramp surface.
- 2×4 lumber for the support frame and structural bracing.
- A reliable drill with wood screws (1 5/8-inch or 2-inch).
- A circular saw or jigsaw for cutting the side profiles.
- Measuring tape and a pencil for layout.
Always prioritize exterior-grade materials if you plan to leave the ramp outside. Standard interior wood will warp and delaminate the moment it hits morning dew or a light drizzle.
How to make a jump for rc car: The Frame and Profile
The secret to a great jump is the curve of the side panels. If the radius is too tight, your RC car will flip end-over-end; if it is too flat, you won’t get any lift.
To start, draw your curve on a piece of plywood. A simple trick is to use a long, flexible strip of wood to trace a natural arc from the ground to your desired height.
Once your template is drawn, cut the two side pieces simultaneously. This ensures they are perfectly identical, which is critical for keeping your jump stable and preventing your truck from pulling to one side.
Pro Tip: Build your frame using 2×4 cross-braces spaced no more than 8 inches apart. This prevents the plywood deck from sagging under the weight of a heavy 1/8 scale monster truck.
Securing the Deck and Surface
Once the side profiles are braced, it is time to attach the deck. Start from the bottom of the ramp and work your way up to the top lip.
Ensure your screws are countersunk so they sit flush with the surface. A screw head sticking up can easily catch a tire and send your RC car tumbling before it even leaves the ramp.
If you want extra grip, consider adding a layer of traction tape or a thin coat of truck bed liner to the surface. This prevents your tires from spinning out during the approach.
Adjusting the Transition Angle
The “transition” is the part of the ramp where the flat ground meets the incline. A smooth transition is vital for high-speed approaches.
If your car bottoms out when hitting the ramp, your transition is too abrupt. You can fix this by adding a small “lead-in” board—a thin piece of hardboard or plastic—that sits flush between the ground and the start of your ramp.
Safety Considerations for RC Jumping
Jumping RC cars is a blast, but it can be dangerous for bystanders and the vehicles themselves. Always set up your ramp in an open area away from foot traffic or parked cars.
If you are jumping in a public park, check with local authorities or park rangers first. Ensure you have a clear “runway” and a safe landing zone that is free of rocks or hidden dips.
Always perform a pre-flight check on your RC rig before sending it off a jump. Ensure your wheel nuts are tight, your battery tray is secure, and your steering linkages have no excessive play.
Performance Modifications for Better Air
Once you master the ramp, you might notice your car doesn’t handle the landing well. Often, the issue isn’t the jump; it is your vehicle’s setup.
Consider upgrading your shock oil to a slightly heavier weight. This helps dampen the impact of a hard landing and prevents the chassis from slamming into the ground (bottoming out).
Another popular mod is installing aluminum shock caps. Stock plastic caps often pop off under the pressure of a high jump, leaving you with a blown shock and a broken afternoon.
Frequently Asked Questions About How to Make a Jump for RC Car
What is the best material for an RC jump surface?
Plywood is the industry standard for DIY ramps because it is rigid and easy to shape. However, if you want something that will last for years in the rain, consider using high-density polyethylene (HDPE) sheets, which are weather-proof and offer great tire grip.
How steep should the ramp be?
For most 1/10 scale vehicles, a 30-degree to 45-degree angle is the sweet spot. Steeper ramps require more precision and lower speeds, while shallower ramps are better for testing your top speed and distance.
How do I stop the ramp from sliding when I hit it?
This is a common frustration. You can drive long landscaping stakes into the ground through the base of the ramp to lock it in place. Alternatively, attach a rubber non-slip mat to the bottom of the frame for use on concrete or asphalt.
Can I make an adjustable jump?
Absolutely! You can build a hinged design where one end of the ramp is fixed, and the other rests on an adjustable support brace. This allows you to change the launch angle depending on the car you are driving that day.
Building your own equipment is one of the most rewarding parts of the hobby. It forces you to understand the physics of your vehicle and gives you the freedom to create your own backyard track.
Start with a simple, sturdy design and refine it as you learn what your specific rig needs. Keep your landings smooth, stay safe, and enjoy the airtime!
