I run the CC 2650 on 4s and 5s, and it handles 5s just fine. Geared 11/46 with 5s, temps were 160-165 at the end of the run. Geared 12/46 with 4s, temps were also about 160. Geared 14/46 with 4s, temps dropped to 150 for some reason and top speed still seemed slower than 5s geared 11/46. All runs consisted of building up to full throttle each pass and then using the breaks to stop before turning around again. The above temps were taken with an infrared temp sensor, measuring the black sticker on the endbell at a setting of 95% emissivity. An actual thermometer that plugs into my eagletree and attached to the can with thermal paste and masking tape consistantly recorded temperatures 30 degrees cooler than the temp probe. It's hard to say which one is more correct. I would imagine if the motor was really ever 160, I would have burned my hand by now.
