Mini 4WD Brake and Jump Simulator (Public beta trial)

Are you still guessing whether your brake setup is good enough for the challenge ahead? Our Mini 4WD Brake and Jump Simulator can take some of the guess work away?

Our Mini 4WD Brake and Jump Simulator (v1.1) is now ready for its first public beta trial. You can access it by clicking here or on the picture below.

Introduction

This is a Mini 4WD simulator where you can experiment with different motor, brakes and tyres combinations and see how the car might behave going over an obstacle such as a slope jump section before finalising your setup. It will show you the height of the jump, the landing point and the rebound height. The parameters are based on scientific experiments we did in the past. You can also enter your own. Hit the green button when you are ready to run the simulation.

In the simulation, you can pause and continue, adjust the playback speed (default to 1/4 of real-time speed) and zoom into a specific time. Hope you find this useful.

Limitations

The simulator does not simulate motor torque, hence the car speed is near constant after braking. The simulator does not simulate air friction. For rebound simulation, it assumes the tyres touch the ground first, not the bumper. And many more.

Updates

Recent updates include:

• Two new table top obstacles
• Three new speed entering methods:
  • Enter speed in km/h from portable speed checker
  • Estimate speed based on Tamiya Mini 4WD motor spec
  • Estimate speed based on motor RPM
• Displaying photos on parts selection:
  • Motor selection shows a photo of the selected Tamiya Mini 4WD motor
  • Brake selection now showing a photo of the selected Tamiya Mini 4WD brake pad sponge
  • Wheels and tyres selection now showing a photo of the selected Tamiya Mini 4WD wheels and tyres
• Simulator shows take off point rather than brake starting point and it calculates the distance between take off and landing.
• etc…
