If you've got little airflow, it's true that you might overheat things. Good airflow is way up there in importance.
3500KV alone, won't cook things, though. I've been flying my Bixler (actually a SkySurfer, same difference) with a 2835-3900KV motor for more than a year now, and a 40A ESC and 2200mAh 3s battery, and haven't cooked anything yet. In fact, the motor's barely gotten warm.
Only time it gets warm is when I do vertical climbs... because that's almost the only time I fly full throttle with that motor. If you fly full throttle all the time with a motor that powerful, then you should get a Spitfire or some other plane designed for that kind of speed/power. The Bixler is a powered GLIDER, don't forget!
Powerful motors like that are mostly for occasional stunts in a plane like a Bixler. You'll probably do most of your flying a half throttle or less - which gives you decent climbs and even stunting ability with the Bixler. Full throttle are for vertical climbs and occasional wild stunts.
As I said, if you spend almost all your time at full power with a motor like that in the Bixler, then you're probably flying the wrong plane.
