osepp motor shield & Acrobatic Junior runs turtle speed and dying.

I brought this.

and this

It moves like turtle speed and can't hardly move while putting on the ground.
AFMotor won't work on newer Arduino program (too much errors). But it works great with old arduino.
How do I speed up like regular RC car?

I plug in M1, M2, M3, M4 on regular motor.

#include <AFMotor.h>

AF_DCMotor motor1(1);
AF_DCMotor motor2(2);
AF_DCMotor motor3(3);
AF_DCMotor motor4(4);
void setup() {
  Serial.begin(9600);           // set up Serial library at 9600 bps


}

void loop() {
  uint8_t i;
 
                motor1.run(FORWARD);
                motor2.run(FORWARD);
                motor3.run(FORWARD);
                motor4.run(FORWARD);
                     
                motor1.setSpeed(255); 
                motor2.setSpeed(255);
                motor3.setSpeed(255);
                motor4.setSpeed(255);
}

I can't find external motor power on osepp motor. I don't know which one is external power. Can anyone help. Oh man. It's slow. I can't read this blueprint.

What are you powering it with?

Do you have the power supply selection jumper set correctly? In one position, it's powered by Vin pin/barrel jack, in the other position, it is powered by whatever you connect to that terminal.

Where are the specs for the motors you're using? They have a voltage and current spec...

Where is the diagram of how you have wired it?

The problem is likely an inappropriate power source.

4 AA batteries or USB plug. Still runs very slow with this dc motor.

The wheel moves by holding up the air but it won't move on the ground.
