Interactive Interface

Real-Time Adjustments, Instant Feedback.

Our tool replaces boring text inputs with fluid sliders. Every adjustment instantly updates the visual representation of your RC car, helping you understand how hardware changes affect ground clearance and stance.

Interactive Sliders

  • Wheelbase (120–350 mm) & Track Width.
  • Tire Outer Diameter (OD) & Width sizing.
  • Shock Length & Spring Rate stiffness.
  • Motor KV, Voltage, and Gearing ratios.
  • Incline Angle (0–45°) for hill testing.

Dynamic Canvas Visuals

  • Rendered tires with custom treads and rims.
  • Animated shock absorbers that react to length changes.
  • Transparent cyan chassis plate and red body shell overlay.
  • Visual incline physics rotating the ground and vehicle.
  • On-screen yellow indicator for live Ground Clearance (GC).

8 Built-in RC Presets

  • MJX 16207 (1/16 Short Course / Basher)
  • WLtoys 144001 (1/14 Buggy) & 124017 (1/12 Drift)
  • WLtoys 124019 & MJX 14209 profiles.

  • Custom mode activates instantly upon manual slider tweak.
Speed & Physics

Go Beyond Looks with Advanced Analytics.

Speed & Drivetrain Calculator
  • Calculates final Gear Ratio automatically based on Spur and Pinion teeth.
  • Estimates raw Motor RPM utilizing KV, Voltage, and electrical efficiency.
  • Computes accurate Top Speed (km/h) by mapping Wheel RPM to Tire circumference.
Advanced Stability Metrics
  • Monitors Center of Gravity (CoG) shifts based on chassis weight and height.
  • Analyzes Wheelbase-to-Track Ratio for cornering stability index.
  • Calculates Suspension Travel and Approach Angle for crawling capabilities.
  • Power-to-Weight Ratio (W/kg) for acceleration estimation.
Utility Tools

Save, Compare, and Export Your Perfect Setup.

Local Storage Configuration

Never lose your perfect tune. Use the 💾 Save button to store your current slider values directly in your browser. Hit 📂 Load to retrieve your setup instantly, even after refreshing the page.

Comparison Mode

Trying a larger tire? Activate Comparison Mode to lock your current specs as a baseline reference. The UI will clearly highlight differences in Ground Clearance and Tire OD so you can evaluate the upgrade.

Export & Reset Views

Capture your setup visually with the 📸 Export Image tool, generating a high-res PNG of the canvas with a timestamp. Easily revert testing angles using the ↺ Reset View button to drop the incline back to 0°.
