For Performula:
I wrestled with the break in mixture on mine also. Finally asked a fellow here at work who flys RC planes and helicopters to help. He immediately disgnosed it as a lean condition and we finally started break in with the HSN out 4.5 turns! A couple of tanks later, he noticed the backplate screws had backed out and thought this may have contributed to the lean condition. Tightened the screws and instantly ran smoother. I was not aware of how sensitive these little motort were to the smallest adjustments.

By the way, as suggested elsewhere on this thread, Frankie at Full Throttle Hobbies in SC has been really helpful. When a shop takes the time to call you about the details of a $60 order and offer you cost saving suggestions - that's great customer service! Likewise, Horizon Hobby was first class in their handling of a warranty issue. This car seems to have a great dealer support system. And that's whats important to all of us after the sale, right?

Finally, just a pat on the back to everyone I've read on this thread so far. There doesn't seem to be the smart alec comments, biased opinions, etc. as on so many others. Good info from people in sharing a good thing - this Mayhem! Keep up the good work . . .
