Hey guys,
Just got done with the first 15 minute full throttle run of my Kraton 6S with the Hobbywing Max 6 and 4985SL motor. I don't currently have a heatsink or fan on, but the ambient temp is around 55 F with a nice breeze. The surface was dirt, short dead winter grass, and concrete.
When I got done, I checked the motor and got 176 F degrees. That seems really high to me for this big of a motor and that short of a run. The ESC wasn't anywhere near that, sitting at around 110 F, but the capacitors were pretty hot. Now, I am running a fairly low end gearing and setup for the Kraton and I don't think I should be having these type of problems. I'm running 6S with the 16 Tooth pinion and stock spur gear. Diff oils are at 30k front and back and 300k Center. All the wheel and diff bearings are new, and it rolls really easy and smooth without the motor in it. I'm running the larger dBoots Backflips tires from the Outcast 6S.
The truck is maybe a hair faster than stock, though it certainly much more torque. There does seem be quite a bit of rolling resistance with the motor installed, but as far as I can tell the drag brake is off. I figured it was just the larger magnets in the motor not wanting to spin.
ESC Settings are normal:
Punch is set at 3
Drag Brake is off
Timing is at 0%
Do I really have to have a heatsink with just the 16 Tooth pinion? Could I have bad motor bearings maybe? Should I contact Hobbywing support?
