Slope Jump Section mapped

Table of Contents

We have recently mapped the curvature of the slope on a Tamiya Junior Circuit Slope Section in order to study the effectiveness of brakes and flight trajectory. After a painstaking process of taking measurement points and cross checking, we have the result (in mm accuracy)!

While many would assume the curvature is symmetrical, meaning the curve going up is similar to the curve flattening on the top. Many models and illustrations we found on the internet are like this. However from our measurements, we found that it is not the case, it is actually asymmetrical with a steeper up slope and a flatter plateau. The steeper up slope curvature design should help the brakes to engage sooner.

The slope section base length is 54cm (standard junior circuit length), slope height 11.85cm and slope incline angle is 15 degrees.

A Tamiya Mini 4WD with a rear brake mount and grey brake sponge

How good are your brakes?

How good are the brakes on your Mini 4WD? Do they perform as good as expected? We have a model to help you plan and estimate your setup.

Friction

What is friction? Do you know how it relates to the weight of the object you are trying to move?

Tamiya Mini 4WD Sponge brake pads green, blue, black, white, grey and red

What is the difference amongst the Tamiya Mini 4WD sponge brake pads?

Do you know how to rank the Tamiya Mini 4WD brake sponge pads according to their stopping power? Do you know which one is the strongest? Is hard better than soft? Is red stronger than black? We conducted a scientific experiment to measure the frictional properties of the different brake pads and rank them according to their stopping power.
