Low voltage cutoff activates now before high temp cutoff, can get about 8-10 minutes run time on 6s 50c 5000mah. I moved down to a Seaking 120a as I want to save the 180a for a new boat if I find one in need of an esc, the 120a gets warmer but still nothing like the stock Traxxas esc. On 4s I think you can have fun all day long with the 120a, but if you're running those batteries in 6s you'll definitely want the 180a. I now have the Seaking 120a in both the Spartan and M41, waiting on the Leapard 1700kv motors and going to sell both to get something higher end.
One of the biggest things with any of these FE boats is cooling, the rudder water pickups are a great idea but they simply don't flow enough, at least the stock Traxxas rudders. The dual pickup setups are better as the esc and the motor have individual feeds, but again the volume of water just isn't sufficient for the current these tiny little works of art demand.
Actually the water pick ups are sufficient in just about every case. Dual pick ups even better. 8-10 min runs can result in residual heat build up, and testing temps by finger touch is very subjective. Get a temp gun to know for sure. There are a lot of threads on this forum to do with cooling, try the search function and have a read of some.
