BoneCrusher,
The following two suppliers sell the systems in Australia. You can also get them from RC mart, RC market etc. We did not do a club buy, however the systems come with the motor, speed controller and setup card. Only thing most change is the punch setting and timing setting. These are normally set to max. Two links.

This has been great for the mini scene here as before you either had motors that were fast or you got left behind. Now there is pretty much equality and as stated comes back to car setup and driver.
We have seen the numbers increase in mini by having the BL system and the MO5 because it is easier for new drivers to get to grips with. They still require work to make them fast and stable.
BTW,
Not trying to say we have it here in Australia 100% correct, but we are along way from where we were.
Later,
Calvin.
