Ok so I started the tank up pressing holding the power button on the remote, the message on the screen says pairing then goes to pairing failed. The smoke works and the forward and reverse work the sound works the recoil on the barrel works sometimes, the turret left a right does not work, the barrel up and down doesn’t work very well and lights in front and back are blinking. The main lights do not come on. One other thing the power light on the remote is blinking. Also how long do you charge the battery
