For me, setting up a gyro is basically increasing the gain until it starts wagging then reducing just a little to stop the wagging, then test in fast forwards/backwards to check it doesn't wag, usually it doesn't, and that's it. I've done this on many helies since 15years and always worked well.

With my 250SE/750 and general tail wagging problem (see my other post), it's a little different.

Basically, whatever I do it wags. It either wags large and slow (about 30° at 2HZ) when gain is low (8 in GY1 Mode) or wags small and fast (about 5° at 8HZ) when gain is high (45 in GY1 Mode). If I go even lower, it starts to become dangerous as it starts spinning uncontrollably (also there's a bit of wind).

For me high frequency (8HZ) and small amplitude (5°) wagging is too higher gain. But what is slow wagging and large amplitude trying to show me? I've been thinking about this, but don't really have any ideas?
