The red ones are from Tank Army, and they also sell the black ones. The red ones are the same size as the Promax 480s, and the black ones are the same size as the Promax 400s. I have all 4 kinds. I don't run my tanks very hard, so I am sure I won't be able to feel the real difference, but in terms of power I would say the red ones are somewhere between the 400 and 480, but RPM wise it is definitely higher when you go full throttle, and it is WAY noiser than the 400s/480s, and not the good kind of noise.atcttge wrote:I would really like to be clarified if these red motors are as powerful or almost as powerful as the 480s.......
I am certain the torque curve is also different, as the 400s/480s are much more gradual whereas the black/red ones are like 0-60 in warp time which is not ideal for tanks.
If I have a choice it would be Promax, but the red and black (and now the blue ones) are cheaper in general.
