Electronics for Turret?!?

[jayd177]

Hey all,
I found some interesting things inside of my controller and tank. I popped open the controler and to my surprise I found two solder points that had no wires soldered to them, labeled M+ and M-. So, out of curiosity I opened my tank and found that the left motor is soldered to two points called LM+ and LM-, and the right motor is soldered to two points called RM+ and RM-. Are we starting to see a trend yet? Now get this. Above the LM+ and LM- there are two more solder points with no wires coming from them and they are labeled HM+ and HM-. Exciting, huh! I believe they fully intended on making the turret controllabe and took it out for whatever reason. This could also explain why we see a lot of those curious 4 shoulder-button controllers in pictures (like on the back of the box). The upcoming sub controllers look very similar, but they're in a different color scheme.

Well, there's a snag. I tried soldering wires up to the contollers' M+ and M-, and an extra to a ground in the controller, and I soldered one of my little motors to HM+ and HM-. I tried all combinations of circuits and unfortunately, nothing happened. the tank was definately charged. I may have goofed the soldering job. I may have the wrong ground to complete the circuit. Maybe they just never programmed the IR for that function since they scrapped it, but it was cheaper to leave the manufacturing equipment the same. I really need someone whose better at electronics and pcb's than I am to look into it.

I'll keep messing around with it and maybe I'll stumble across something that will work. I'll keep you all posted. Jay
