I am going to get a slow stick 300 to play around with in the backyard, but I am unsure what size battery to purchase. I already have a Hitec mini 6s rx, 2 HS55's, and a c-12 esc. I also have a Nimh charger so that narrows it down a bit. I was also wondering what kind of range I can get out of the 6s. I don't need to go far(only have a couple acres), but I want to know the limit of the receiver before I figure it out the hard way.
