I found that my output shafts on the V3 are now getting hot. I find the most important thing is to make sure all of the bearings move really free especially in the hubs as as soon as there is any resistance build up there the output shafts, motor and battery temperatures start to rise. I usually use SMD bearings which have one metal shield and one rubber shield as these have less resistance on them than the dual rubber shielded bearings. In fact you could run a fully metal shielded bearing on the inside of the gearboxes for the output shaft for least resistance. The other thing to pay attention to is the gap between the bearings on the output shaft as if the gap is too small it can cause friction on the bearings and if the gap is too big then the pinion can move inside the plastic gearbox case. I also build up the areas of the plastic gearbox case where the bearings fit otherwise the pinion can move around a lot causing heat and damage to the ring gear. I also make sure that the ball joint and ring gear are lubricated with teflon grease and that helps to keep the temperature down. As soon as I feel the temperatures rise I know that it is time for a strip down and clean to make sure everything is spot on.
