I'm using a Mystery A2208-14 1450kv motor on my Blunt Nose Versa with a 9x6 prop (G/F 3 Series Master Airscrew). I was buzzing around yesterday at about 3/4 throttle and noticed on landing that the motor was fairly warm. I measured it with an infrared thermometer and came up with 120F as the temp on the motor. Hot, but not hot enough to really burn when I touched it. Is this ok? Too warm?
How warm should a motor be?

I'd say that is ok temp wise, but that motor is way over propped. You might want to prop down to an 8x6 or 8x4. You probably won't notice a loss in performance, and the speed should be slightly better with the 8x6. Not to mention it will be better for the motor.
Oh, 130 on the inner part of the motor is a good max, much higher and stuff starts cooking.
I hope this helps!

So the way I fly probably puts the motor right at its limits? I'll go up to full throttle occasionally for hard climbs and loops, but usually fly around right where I was where I measured 120 on the motor. I guess I'll have to go grab smaller props from the hobby store tomorrow (or maybe a slightly tougher motor).

Yes, or over its limits.
If you have some soft landing surface, I'd pick up some GWS HD props along with an APC or 2. The HDs are very efficient.
