I was going through my TX and figured out that I can assign the Gyro to a channel. I had it on the gear channel. I switched it over to Aux 2 channel (Dx7s) and poof it was making the corrections and I got-R hovering. Now I havea wag that I need to chase down. I am new to the Dx7 and didn't know that you can get into negative Gyro adjustments...... Now what you all are telling me makes more sense. (Sorry for being a slow learner) The wag seems to get faster as I go up in numbers, but the lower i go the wag gets slower and wider( swings wider) I should be going lower, to make it go away, is that correct?
Now your getting it!
Slow drift wag is not enough gain, fast twitching is too much gain.
On my DX7s on my 450 w the 3gx I think I was at 39.5% in the radio.
They say to start high and fly then come down in like 2% increments.
Hope that helps!

another thought, I had my 450 wag like your describing and it was due to not having correct center when I set it up the first time.
Turn the tail gyro off as in no gain AKA( NR mode) let the servo center and fold both tail blades up and see if they are lined up if they are pitched in or out adjust the linkage until you are as close to both blades being lined up as you can get.
This is my cheat way of trying to get centered.
Then go through the tail setup again, also when doing the tail setup DO NOT have gain in the radio, I normally left the 0 position on my aux2 or gyro switch to where I could turn off the gyro for setup reasons.
