I just received my arrma Kraton and I'm stoked. Thing is scary looking just sitting on the shelf waiting for batteries. Well based on forum reading, reviews, YouTube, etc I decided to go with a 5s lipo from rc juice for a happy medium. After reading some conflicting info with some guys saying that the v2 esc could detect/cutoff successfully on its own and others saying it won't and you would have to use an alarm I decided to email customer support at arrma and ask direct. They responded by saying that it could not detect 5s and there was no workaround by using an alarm/nimh mode. So - is he just giving me the "company" response or should I be concerned with trying to run a 5s? Thanks for your help all. Look forward to running this beast!
