Do you trust that styrofoam belly to hold that big ol' battery in at 6Gs? Just a thought. As long as the battery is sufficiently isolated from the airframe there won't be a vibration problem. </p>

I still use NiCads and charge at the overnight rate so covering them completely is not a concern. TedMo's suggestion of a lighter battery and a spare sounds reasonable to me. As long as access isn't too difficult. A 1200mah vs a 2600mah ould save quite a bit of weight. You check the battery after flights, right?</p>

Those Focuses are good looking planes.</p>
