BMS-630MG or BMS-660MG

since mike doesn't carry the jr servo i was going to get any more im i need of a new idea for stearing servos,ill be running 2. they have to same specs the same size but the only diff is one has a heatsink built in. which one is better? does the heat sink do anything?

Under super stressful conditions (or just for cool looks) the alum. case on the 660 will dissipate heat from the guts, most importantly the motor. Outside of rock crawling, I haven't heard much about people heating up their servos, turning the wheels while having forward momentum may be less than easy on them, but just doesn't carry the load of a heavy Clod or Maxx or TXT shifting all the weight to the rear axle on a steep incline........and telling the servo to kick the wheels to one side. Bashing may beat a servo to death too, but crawling has to be THE hardest form of rc on the electrical components.

i think ill just get the 630mg since ill have almost 200oz of torque per wheel:L: dont think it will heat up much cause of strain:)

I have a 620mg in my revo and it starts to fade in performance at about a half tank. I have a spare and will try this before i say wether or not the 620 is good for mt's.
