tekno BRsh kit for 8ight 2.0

Ok, really like the tekno kit for my conversion, but just would like to get a little more feedback from others. I like it because it comes with a machined frame which would replace my cheaper RTR stamped unit. Also, the ability to adjust brakes and use the direct drive or electra-cltch. My main concern is that I have heard I might need a better controler for some reason. I have the dx3s, also does the reciever fit in the box the supply. Any opinions or feedback would be greatly apprecited.
