Here's the setup for my t34 smoke unit. I'm using a y-harness for the DMD's throttle channel and the electronic speed control. The setup is very effective. Clean, quiet and plenty of smoke. Looks great when the tank turns into it's smoke. The downside is that power consumption is very high. I have two sub-c 7.2volt battery packs. The tank's run time is 15 minutes. Any leads on sub-c battery packs with a higher capacity rating? Thanks!!
