Your link don't work. I am going to take a stab at it and guess "Megatech" the purple motor. I tried one in the past and was not that impressed with it. The X-speed is better. Also those Megatech motors you will need to open up your motor mount for it to fit. They are made to fit the megatech pod and then you will find out that you need the diff as well and so on and so on.
