Hey all, this is my first post, and first Arrma. I just picked up a barely used Limitless because there is an asphalt track nearby (pic attached) that runs 1/7 racing seasons, and boy does that look like fun! Limitless, Felony, Infractions. My car came with the 160a/1250kv Spektrum setup. I'll be running it 6s, because, that seems prudent, and it came with 2 3s batteries and I have two others. I'm wanting to put in a center diff for better handling and cooler temps. Arrma has ton of diffs on Jenny's RC. There's the new Fireteam 50T, the Felony 50T, the Mojave 50T, Infraction 46T, Kraton EXB limited slip, on and on. How to choose? Anyone else running s 1250 setup for track that can give me some advice?
