High speed uncontrollable remote control car

The remote control car is too slow! ! ! I can't stand it! Make one yourself! Just go ahead and complete this super powerful work based on ARDUINO mobile phone Bluetooth control, all handmade. Welcome to learn. to avoid detours! Author: Walking on the Edge of the Universe https://www.bilibili.com/read/cv6217381 Source: bilibili

This is the 11th generation finished car. The performance has been greatly improved. The project has released the schematic diagram and PCB. You can download and use it yourself.
