Bob,

Typically, the battery is used to get to the proper CG range when = the plane=20 is finished in construction.

There=20 can be significant difference in battery location per plane depending on = the=20 builder. As an example, my early airframe has the battery behind = the=20 passenger seat. A friend's early airframe has his battery just=20 behind the baggage bulkhead. Another friend with the same = airframe=20 has his battery farther behind the baggage bulkhead.
