It balanced perfectly with the .40 and the battery towards the front.

WOW!! Even with the .28 I had to put the battery pack between the servo's and the next former back to get it to balance! With the .40 I had to put the battery under the vertical fin! The one with the .28 was originaly owned by a friend who had an OS .46FX in it. He had the battery pack in the area by the throttle servo and about 3 oz. of lead in the very tail end!
