Hi acdii, That weight is before balancing. I don't really want ~4oz of dead weight hanging out on the exterior of the plane. Since I'll need to open the tail anyway, I'll see where the battery needs to go (2100mah life) and work on moving it further back before I think about internalizing any dead weight.

Cowl on mine will be staying off a bit for similar reasons. The engine has been sitting on a shelf for a good bit. While it looks & feels OK (it had a nice dose of corrosion x before going into storage), I expect that it will have some tuning issues before it is to a point where I am comfortable hiding it within a cowl.
