CRT Setup

[skellyo]

It may help in some situations, but that gearing is too much for that motor IMO. In my CRT, I run 4S on a Neu 1515/1Y geared 13:62, which is right about 36mph. I'm about to jump up to 15:62, but with the temps I have (motor and ESC under 130F) I don't think I'll have any issues. If you want something that will run well on 4S, I wouldn't run anything lower than the 1515/2.5D (1650kv). If you went with that motor, I'd probably start with the gearing somewhere around 18:62, which should get you into the 37-38mph range.
