These look identical to the ones I bought last year. They have held up very well. On the ones I've bought, the black is the 49MHz & the blue is 27MHz, so we can run these 2 at the same time. I think the red is 49MHz.
Left lever controls left wheels, & right lever controls right wheels. Hold both levers to go straight forward or backward, and the button on the front is to speed quickly fwd. You can make them spin holding levers in opposite directions.
