FWIW I run a 130T on 7.4v in my SCT410 and a 170S on 7.4v in my ET48. My SCT410 has roughly 50 packs through it and it works as well as it it did the day I installed it. The ET48 has maybe 10 packs and still works great. The 170S is an absolute monster! They are both very fast but I like my stuff twitchy. I cant wait to see how the 170T is in my Yeti XL as soon as it gets here.
