The cg is supposed to be right on the wing joiner, which is an aluminum bar as opposed to a tube. There isn't room under the joiner for the tanks. I thought that if the fuel tank went up front then the smoke tank should go in back. I've got room up front for both without the throttle servo in the way, and there's also room behind the joiner for both. So should I put them together or put one in front and one in back, sort of sandwhiching the joiner? And when I balance, should I balance with both tanks full or empty?
Thanks again for helping a rookie!
