That was all Horizon Hobby said, in as much as My original question was about the Tail Motor burn out. I gota think they are talking about the main motor pinion.
I saw wer bdavison had this comment about the pinion change in and earlyer segment of this Posting.

I'd been flying around on the stock 10T pinion'd motor, so I decided to upgrade. The aerobatic enhancement kit comes with a 9T pinion. But Im nuts, so I went a step further and put a 8T pinion 370 motor in it...HOLY MOSES....

The head speed is really ripping now, and its smooooooooth as glass. The heli just gingerly lifts off the ground. And stays in a DEAD still hover. Its literally like its sitting on an invisable table or something. No more of that skid shaking slow head speed rattle, its smoooooooth.

The tail motor smoothed out too. Its not so twitchy. So basically drop the 9T or 8T pinion'd motor in yours. You'll notice a big difference. Run a 1320mah 3cell lipo and fly around for 25 min. I would recommend the TP 3cell 1320mah for max performance.
