RE: Graupner Extra 300S Battery Options
Here are some options for battery power on the Graupner Extra 300S.
[ul][*] 16-cells CP2400 NiCd (in yellow) = 34.7oz[*] 16-cells CP1700 NiCd (in black) = 27.0oz[*] 4s3p Kokam 1500HD pack (4.5AH, not shown) = 16oz[*] Kokam 4-cell 2AH pack (in red) = 11.0oz
[/ul]
As shown, all these packs fit perfectly in the Extra 300S. The packs vary in weight and cost. The NiCd packs are placed in positions that will likely make the plane nose heavy so they can be moved aft when I can test the balance after my rudder servo arrives.
We are still waiting for pricing on the new Kokam 2AH packs but it will be an interesting test to fly a .60-size Extra on only 4 cells of Lithium.
