I vote against 3S also and say 4S min. Fans can do wonders to temps though. Maybe thats how JSR keeps his motor so cool. I can keep my Feigao 7xl ice cold with 2 40mm fans and the novak heatsink. I've run it for years now without issues. Without the heatsink and fans it would not have lasted a single run. I was easily reaching temps of 170 without much effort without any of that stuff. 3S is something we used to talk about in the day when there were no such thing as 4S controllers and people experimented and came up with 3S just being too low a voltage for a heavy truck running a descent mph. I am having a bit of trouble though with the controller being at 80 to 90 degrees on an 80 degree day. Even my best MM on 4S got hotter than that with a 40mm fan on it. I would be interested to see if JSR is running any fans on his esc and/or motor to stay that cool.
