i cant work out whether your answering your own question or not but anyways the gm genius will work pergfectly with the kontronik which is a very good 2 pole motor.
However there are better controllers for the money for example a mtroniks pro or my favorite the mamba max with its abilty to Be configured via a usb conection with the castle link software.

From what have seen of someone driving slow with a gm genius controller its not as smooth as the mamba max but i personally would like to know what sensorless controller is maybe the quark but there overprice and have bad cases for rc cars.

all in all so what do i recomend.

Well firstly I would definatly go with a mamba max controller.

if you can get a kontronik twist cheap then there great motors especially for touring 1/10th.

otherwise the mamba max 7700 combo is great for standard 6 cells or if you want the option for using 3s lipo the 5700 combo would still be really powerfull but have the option to possibbly vaporise your transmission with 3s.
