Both Jags and Victors use power FETs in the motor drive output. These devices contain a internal diode across the source drain terminals and when voltage is applied to the motor terminals, the diodes will conduct. This high current is manifested by the smoke released during your power on. Unfortunately all four controllers are damaged. I am guessing these were Black Jags.
