Brent,
Try the 830 or 860 3cell packs. I like it light!
I think I like the 9x3.8 alittle better then the 10x3.8,but the 10 is fine if you like it.
I have my CG about 1/2" in front of the hinge line on the top wing.
I use the 830s and I place on them inside the fuse over the lower wing.
Makes the hover real easy!
