I'm confused ... I'ved used 3004 Futaba servos on my trainer, my 4*60, and my WM T-34 ... no problems. I'm stepping up to a more aerobatic plane and I've heard that its a good idea to get a stronger servo for the elevator ... I was looking at the 3010. There is a warning regarding battery size and draw ... I'm lost ... I've always just used the regular Futaba NR4J Receiver NiCd Flat 4.8V 600mAh J battery ... do I need a different one? Should I use a different one?

I have no idea about different batteries, draws, and servo torque and I thought there might be others who could use a quick lesson from those of you who know. Anyone have time to give me a quick education?

By the way, I'm getting a WM Cap 232-46s ...
