Yeah My losi is a servo eater to.I have burnt 2 590`s and a friend of mine has bent 2 650`s.Itrs not do to heat either our engine temps were running around 150 175.Its was 60 degrees out last night.We always made sure that all of our epa adjustment were correct and that the servo didn`t have any strain put on it.We also don`t use the brake we only use it to open the carb.WE run dirt oval and brakes arre just not important and not needed.
