Is this temp is too hot???

I've take my e-revo for a first real bashing session this week end in a send pit. I've a Neu 1515, 2.5d/f, an MGM 16018 controller and i run it on 6s.

I'am gear for about 41 m/h. When i've run it on the street somes days before, i've never exceed 130 on the motor and ESC, and about 86 on the li-po.

But this week-end, on the send pit, with lot of WOT in a very soft sand, and multiple hill climbing, i've take the temp after about 15 minutes of realy hard bashing, and it was 165 on the motor and ESC, but the li-po never exceed 100.

Is this to high for Neu motor????

I'am plan to gear it down 2T on the pinion for the next sand pit bashing session

But this day was realy funny, and i can easily kick the ass of a Losi eight-T truggy with an OS 28XZ in it

Thank you!
