Well I am learning the basics in my living room barley lifting off staying in a box so far so good I have learned the hard way to take the time and setup the helo, and recheck everything. I am still having a little trouble though. The helo wants to drift to the right. I checked balance the helo I checked swash, linkage battery placement tail blade balance. I was wondering if I am missing something. I check, and played with gyro and pot settings I made sure to power down and powerback up after all setting changes. Checked all the trims, and even with it set to the left all the way still drifts to the right. i can compensate with stick, but I need to really get this helo setup right before another outside flight.

Whe setup and trimmed properly it should want to drift a little left upon initial take off. If it needs constant left stick input with full left trim then something needs to be adjusted mechanically.
However I am sorta stumped since you said you already rechecked that the swash is level. If you find later that the swash links do need a little adjustment, just make sure that the trims are center and tht you level the swash in perpendiccular refference to the main shaft.
