Well, actually I found a BEC switch at the hobby shop that is designed for use with brushless motors and I'm using that now. I'm not too worried about the weight penalty because as long as my plane flies, I'll be happy and I don't see this thing weighting it down too much. I know I can't just turn off the switch and store the battery in the plane plugged in, but it'll help me with making sure everything is out of the way before I get the battery plugged in to begin with.
