The batteries on this model will be two 4000mAh Dualsky 2cell Lipos in a hard casing, these are primarily used for RC cars but will do a grand job up in the nose of this model to help with the CG.
The ECU will have a JC 3300mAh lipo and finally the lighting will be powered with a 6v 2500NiMh. I've made four ply battery boxes that are hysoled into the nose. Hopefully this will avoid any ballast.

I couldn't resist putting it together for a gander. It really is a great looking model. Skymaster have done a great job producing one of my favorite marks of hawk. I like the size of it too should have a nice presence once airborne.

Well the paints nearly dry so better get back to it.....................
