When bk say the motor's rated to 80,000rpm, they're really only refering to the bearings. A BL motor is in its peak efficiency at around 35,000-40,000 rpm (bigger motors will be less, and smaller more) - but for 540 size motors it is this.
As long as you get your gearing right, you won't need your temp gun at all. If you use the first say 5 runs to gauge the right gearing (checking motor/batt/controller temps) and gear appropriately. You should be fine after that. Obviously if it is a particularly hot day, you might want to keep a constant check on temps anyway.
