programming bk 12020 controller

[strodedawg]

last night used a jr synthesized radio and a m8 and the damn thing wouldn't program. just used the ubec and the mamba maxx controller i had for a gt2 conversion i started. i tried to hook up the mamba maxx 5700 motor to the esc, resoldered all the connections and tried with every radio i could find and not response. what should i do with this expensive and useless piece of electronics smash it? send it back and wait forever to get it back?
any comments would be appreciated.

thanks to all that have given me help
