Hi Bob, just re-read your opening post and Chad's.  My money is on the prop.  While I may lose this little bet with myself, what will make me even more sad is if it's the motor.  The advance is a newer design and I have not heard one bad thing about it.  Please prove yourself wrong and tell me it's not the motor or I will be very sad indeed.  A 22x12 on a Nuance is one thing; a 20.5x12 on your slicker airframe is quite another, given your flying style.  If that 12 pitch is just not moving enough air now that the air is warmer and less dense, it stands to reason that more RPMs would needed than before to realize the same performance, only at a cost of decreased efficiency and increased battery drain.  What other props can you test, if I may be so bold to ask?  Or is there something else we need to know about the Advance now that a few hundred flights are accumulating?  I really hope not; and I hope you find out what ails your ride tomorrow, in any case, good luck my friend.  Dana
