The first time out with my .12 capricorn engine I was running in the 280-290's with blue smoke and a little over 5min run time. I talked to some guys, and they say the same thing, run it as long as you have blue smoke throughout the powerband. Just make sure you check your bearings often.
I did add an extra head shim, temps went down and run time went up slightly.
