You won’t be disappointed, even without the interface it’s a great option, but like the USB link for the Mamba25 it’s even better with it.
I use the male to male servo lead and the USB adapter form this kit

although the serial port adapter should also work. In fact if I had that one I could find which pins are needed for the serial port and make a cable for a fraction of the price, makes me wonder if one of the manuals shows the pin configuration.
Here’s my latest addition to this car, first I added an Atomic BB motor, it worked great even allowing me to use the 350mAh LiIon pack with a 49T slipper gear and 14T pinion without overheating the LiIons, but then I noticed that even though the Atomic BB didn’t have ball bearing it’s end-bell could be modifid to accept them, unlike the stock motor. So I BB modded an Atomic BB and gave it a try, the result is nothing less than amazing, and doubly so in this car.
