Thanks for your input Walt.
I was hoping that I could get away without having to add ANY weight. I'm only pushing just under 400w on a Eflite 25 Outrunner.
Rather than use a weight up front, I was going to move the motor forward an inch or two on four 1/2 inch dowel rods. this should add just a little weight and move the 7oz. motor foward a bit. Moving the CG 3/4 inch shouldn't take too much ?? I only had 2oz. of weight and that was not enough to bring the CG where it needed to be. I'm thinking 3 or 4oz.

About the battery installation... I'm running 3S2P 2100 lipo so there is no room to move stuff around. I knew it was going to be tail heavy so I mounted the servos as far forward and used a light pull pull setup for control in the tail.
