I put a 2s lipo in mine and love it. This sheet was right in with my manual of both of the cars I bought on Christmas Day. Once again flyinwalenda shows up to bash redcat. If you're going to bash a company at least be accurate about it when you say you won't find something in their manual or on their site. For somebody who absolutely hates their products you spend a hell of a lot of time browsing through their forum. I would love to know the whole story behind where your personal vendetta comes from! Must be a good one.
