What happens when a Boxstock Tamiya Mini 4WD going over a Junior Circuit Slope Jump?
What happens when you have a Boxstock Mini 4WD going over a Tamiya Japan Cup Junior Circuit Slope Jump section at full speed (~4.3m/s) with no brakes? Here is what our jump simulator shows at 0.1X (slow motion). We can also see the bounce effect of the car when landing. What do you think? Do […]
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 […]
