Converting Brushless to Brushed Controllers
I have been doing this for a while.

I have converted quite a few of hobbykings controllers. Jump on robowars.org/forum -> under technical chat is the thread. Its pretty long but worth a read if you are really cheap.
This is probably the cheapest one you can convert easily (Avr microcontroller for the moment) https://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=15202
However the HK10 is the cheapest one I have done @ $5.15 for their “one time bonus offer”, current favourite is the TPY1-25 that controller is fantastic. I am running RS550s on it @ 6S which is so far overspec its not funny and it barely gets warm.
