Yea I have a 3s on its way, so I'm going to stick to my gearing for now. Its geared for about 36mph right now on 4s, but when I get my 3s it will go 46mph on 5s. I am going to go to my grandpas farm soon hopefully, so I will get a video. I made a sweet track with a tractor, so I'm looking forward to driving on it. Last time I didn't have batteries.
