Is it creeping over while still or while flying?

Set up the gyro in rate mode with no trim on the Tx. Once it holds good in rate mode, switch to HH and use trim on the Tx. to stop your drift.

Turn the gain all the way up.

Adjust the sub-trim until the servo stays put.

Turn the gain back down to your flying setting.

JR gyros have a set center pulse, if you radio doesn't match you get servo drift. You have to get that squared away with sub-trim FIRST before you do any of the above.
