Which roller is the fastest?
Based on your feedback, we have improved the comparison chart by adding some photos of the rollers. We hope this makes it easier to read. Roller with the least friction is the fastest but certainly there are other important factors to consider too. Read the full report find out more. We used science to test […]
Motor magnets strength measured
Recently saw a post in a Mini 4WD group TAMIYA田宮四驅車情報站 on FB about measuring magnet strength using the “Compass” App. I am not sure how this can be done with the compass app but we did use a Magnetometer App to do some measurements before. We tested 9 motors: Stock double shaft (PRO), Rev Tuned […]
Slope Jump Section mapped
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 […]
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.
