I want to order one of these from www.hobby-lobby.com, and I want to upgrade the battery from the 7 cell nimh that they tell you to buy with it to an 8 cell nimh pack. I am just a little confused, the one they want you to get with the plane says it comes with deans connectors. Is this standard on the packs, or if I upgrade to an 8 cell nimh, will I have to buy the deans connectors or what. Thanks.
