RC CAR Performance and Ground Clearance Calculator

Free Tool

Ever wondered, "How much will the ground clearance increase if I change to bigger tires?" or "What's the top speed with this pinion/spur ratio?" 🤔

Now you can see it LIVE visually, without having to disassemble the actual RC.

We've created a free tool: the NESH RC Simulator & Performance Calculator – an interactive webpage that displays your RC as an animated canvas, complete with technical calculations.

Why You'll Love This Tool:

Interactive Slider – Change the wheelbase, tire diameter, shock length, motor KV, voltage, gear ratio, and even the ramp angle with just a few swipes.

Real-Time Visual – As soon as you move the slider, the RC on the screen reacts immediately. You can see the tires expand, the shocks lengthen, the bodywork move up and down, and the ground clearance change.

Ground Clearance Indicator – A yellow line and "GC: XX mm" label update instantly, so you know exactly how far the chassis is from the ground.

Hill Simulation – Set the angle between 0–45° and watch the car tilt along with the ground.

Top Speed ​​Calculator – Enter the motor KV, battery voltage, and tire size; it instantly displays the estimated motor RPM, wheel RPM, and maximum speed (km/h).

Advanced Stability Metrics – Wheelbase/track ratio, Center of Gravity, Suspension Travel, Roll Center, Approach Angle, and Power-to-Weight Ratio. All calculated automatically.

Save & Load Setups – Save your favorite setups in the browser, and simply click “Load” to bring them back.

Comparison Mode – Lock the initial setup and adjust the new configuration. You can instantly see the before-and-after differences.

Export PNG Image – Want to share your setup with a friend? Take a screenshot of the simulator with a single click.
