I just got my mini revo and charged it over night and ran this morning with out the body so I could monitor the temps. I read a lot of posts about hitting high temps but mine was run completely stock battery and all. My temp got as high as 110 on the motor and esc was 115. I ran up and down my street at wide open throttle as far as i could see (pavement) and since I read alot of over heating posts I ran mine with out ever hitting the brakes just to see what kind of temps i got. I also got about 20min. of run time on one battery. I am gonna hook up my series connector and see what kind of temps I get!
