I've been looking into the TZ85s today, but the only ones I can find are for brushless motors, and to my knowledge drill motors are brushed. Were you suggesting I mod them to be brushed, or are there brushed TZ85s I haven't seen? I'm also unsure on the current draw from 18v drill motors - could I use an ESC with lower current rating? I checked out Ranglebox, 85A ESCs are sold out but 30A ESCs are in stock.
Here Rapidrory suggested the motors need around 60A, but the thread ended with Giles going for making his own ESCs. I'm not opposed to this, but while I'm not clueless on PWMs, I don't think I have the experience to build a reliable ESC at this point.
