Those temps are decent...especially for 28 minutes of speed passes. Speed passes heat up the motor quick. The fact it was in 41* weather though is what worries me. Once the ambient temp gets to like 70 your motor will not be cooled off so much. I would tweak the gearing slightly to see if you can get your temp to go down a little.

What is your ESC temp? If it is super cool then you are likely undergeared and should gear up (larger pinion/smaller spur). If your ESC is rather hot then you are overgeared and should gear down (smaller pinion/larger spur).

I think as a reference just use your ESC temp vs motor temp. If ESC temp > motor temp = overgeared. If Motor temp > ESC temp = undergeared.

If your ESC and motor are around the same (and are decent temps, like 120 or so) then your gearing is dead on.
