Tomorrow I'm ordering a vision , and need a little help. Not sure what else to get with it. It comes with a extra battery , and I'm getting prop guards and a extra set of props. Figure the prop guards will help save the props. Any idea what else I should get while I'm at it ? I figure 2 batteries will be ok at first. It's not my first quad as I have a f450. Shame I can't use my lipo chargers with it. I realize it actually charges with 12 volts.
