QS - I don't blame you... I set my Extra up with an older Futaba radio along with the required servo reverser. I was always fighting problems with that thing, checking weather or not it had vibrated to a different setting (the pot), or weather the temperature had caused the elevator halves to come out of balance. I kept waiting for something to go wrong, and you definately don't need that lurking in the background. If this guy's willing to work with you to fix the problem, then it'll be worth the wait on your part. You haven't revealed anything to us about WHO this guy is anway, so nothing wrong with the post.

Good luck
