[NSRCA-discussion] Going Electric - Battery Questions

[Marty King]

Larry,

I converted one of my Angels Shadow to the same setup. I am running a pair of Chris's (f3a Unlimiteds) 5s 4900 Power Unlimited batteries. 

Flying the Intermediate Sequence once I  have about 38% left. The Advanced leaves about 30%.
