It's a good heli but it's picky about some things and it does not tolerate he-man torque values. Be gentle with those little screws - hold the screwdriver with one finger and thumb and tighten it that way. I'm pretty convinced most of the problems people have with the screws are due to over-tightening - since I've had my 250 almost two years and have only stripped the heads on the screws in the tail, and it was totally my fault.

The tail drifting is just because your setup isn't quite right yet. This bird is very sensitive to super-small adjustments, so you're going to need to fly it to get the final adjustments - eyeball gets you close, but not quite.
