The other phrases that I keep in my head for remebering which way to turn when flying NDBs are:
1) When tracking towards the NDB but a little off course and somewhat confused...
...Turn onto the desired inbound track on the DI, If the needle is right, fly right. If the needle is left, fly left. Until it centers. Then correct for drift.
2) When flying away from the NDB and a little off course...
...Turn onto the outbound track. PULL THE TAIL of the needle towards 000 on the RBI. So if the TAIL of the needle is to the left, turn to the right by pulling it with you. Until it centers. Then correct for drift.
3) The other technique that I use to ensure I'm on track during wind drift is the "Plus" / "Minus" method. If I'm looking to fly my heading say plus 10 degrees drift to the right, then I'm looking for minus 10 degrees (left) on the RBI. (Flying towards the NDB)
The ADF can really get your head in a muddle if you let it... or even if you don't!
