I too have the JR 1800 MA bat, 6 v., guess that's why I only need 4oz, while others have said up to a pound. I really haven't experimented with the CG, it's on the spec. spot, probably could eliminate the nose weight if I wanted.

I almost removed the wing incidence, but the drag of my pilot seems to have solved the problem. Still flys really well on Saito 91.

Here is my pilot of choice, this plane looks so dumb unmanned! With the extra room in the plane I hooked up a sevro to his arm so he waves on the low passes.
