Cooling pump

[Roy1]

Hey, I am new to rc boating and was experiencing difficulty with water flow. Found an old gallon jug of insect killer with a battery powered pump. I wondered if it would work on my boat, so I soldered on a plug and hooked it into my receiver and WALLA ! Unfortunately, my receiver (although 3 channel) needs a CPS switch to be able to turn it on and off from my transmitter; so I had to spring for one. The pump does work very well, especially for free.

What kind of boat and what problems were you having? Pumps usually are just dead weight on a FE boat.
