I just thought I would add this little piece of info. In the begining of this thread it lists the zz heatsink as not compatible with bits. Well, yes it is with slight modification. When I recieved my new microsizer chasis and 2.2 motor I wanted to drive it right away. I noticed the chasis they sent me had no heat sink. I still had the heat sink from the zz tuner kit. So rather than robbing a heatsink from another car I tried to make the zz work. I took out the screw and with a pair of pliers straightend the tab down. Fits and works great. This also alows me to use the zz motors with less hassle. I'm sure someone already figured this out but it wasnt mentioned on this thread.
