So I love my new outcast so far. Probably top 3 RC's ive ever owned in the last 5+ years of being into the hobby. On 4s she is a blast as is, on 6s it is fun in the beginning with the craziness but just a bit too much for me to actually enjoy without fear of breaking something. I feel like 5s could be just about perfect. I have mine with the stock electronics now but I do have a mamba monster X sitting on the bench I could throw in for settings on the 5s.
