A:AnswerAbout 27 minutes but that depends how fast you fly around and how windy it is. Mine goes about 25 miles an hour in standard mode so at full speed on a windy day it can drop to 15 minutes. I bought extra batteries.
A:AnswerThis seems to vary from store to store. You can call your local BestBuy to check stock or visit them. If they do not have batteries on their shelves, you can order them to be delivered to you or the store for pickup. I believe that they will cover the cost of shipping since the batteries are over their cost threshold. Hope that helps.
