My SS5800 has thermally cutoff when using with new cells.
When use with my old packs, they are OK. Thermal cutoff happens once in a while when weather is hot.
Gearing is close to 7.5.
Just put one of those little Reedy fans on the speed control, over the fins...works great. It drops the temps by 40-50 degrees.
It really shouldn't thermal that easy though...you might want to send it in. I had one that would thermal easy and I exchanged the ESC and it hasn't thermaled since...even geared down in the low-mid 5's.
