You can CA the gear to the TT. Just be sure it spins true before the CA sets. A better "fix" is to ensure the TT is seated fully into the B gear. You might need to grind down your boom a few mm's to allow the TT to seat further into the B gear. What happens is, if the TT isn't seated fully into the B gear, the TT can move forward and disengage itself from the C gear, especially if it isn't CA'd on. When that happens in flight, obviously, the C gear gets flung into outer space never to be seen again and you lose tail control = throttle hold/crash. I set my mesh by fully inserting the tail boom into the frame and TT fully into the B gear and then back it out just a *touch* to prevent any drive train binding. I also CA the C gear for good measure. Works every time for a nice, smooth and reliable tail.
