Mack Granite with Dump Trailer

The new dog house looks pretty good for only using basic tools, Aaron. I didn't think the UMS pump was that small! Gee, maybe I could fit one in my truck someplace after all.

As for running two different battery packs - one for the pump, and one for the truck's drive motor, you should be able to do that without a problem, and use the same receiver for both. Assuming your ESC are identical, you don't have to worry about pulling the red wire of off one ESC, even though they will be running different battery packs and voltages. Their internal BEC output should be almost identical, regardless. If your ESCs are different, and have different internal BEC output ratings, then pick the ESC that has the more capable internal BEC, and pull the red wire off the ESC that you don't want to use. Or, buy an external BEC, and pull the terminal pin for the red wires off both ESCs. There are a couple different ways it can be done.
