At the bottom of the header page is a web site called Watt Flyer. Because I have no knowledge of electrics, when I convert something I always go there. They have a great beginners sticky that tells pretty much everything you will ever need to know about it. In my area a lot of us go together and place one big order from Hobby King for our electric stuff. Batteries, ESCs and Motors. We even get new gas ignitions from them and I'm really sold on there covering. Now days there is a lot of this stuff sold through there US warehouse so it saves a lot in shipping.
