I use gain on the retract switch, that's if I use more than one gain. A gain that is low enough to cope with the higher speed parts of flight still helps a lot at landing speed, it's not as if it stops working at low speed. You don't really need a third gain for mid flap. Two settings - a high speed and low speed gain are plenty. Generally I don't use a gyro's banks, if I am using two gain values then I switch them direct from the retract switch. I have a separate 2 way switch as my Gyro Master, common to all model setups on my Tx, which can switch the gain value back to zero should the gyro get loose, go mad etc. I think it is dangerous to not be able to zero a gyro from the Tx. For test flights i have the gain assigned to a rotary knob not the retract switch, and i take off with the Gyro Master switch at off, and the gain knob turned down to zero. Then when ready at safe height I turn on the Gyro Master switch and start turning the gain knob up. After the flight, I transfer the values from the knob to the retract switch. My latest Tx has gyro software that remembers gains set in different flight modes so I will be using that in future

A lot depends on personal taste. I like the gain to collapse quickly as I move the stick so I altered the priority and the balance between the gains of the different axes before the maiden flight. If you are not so experienced or confident with gyros perhaps it is best to start with factory settings and if they feel fine, then you need do nothing. If you feel the gyro is "fighting" you then it probably needs the priority changed.

I suggest leaving everything at the default bank settings except for copying bank 1 to bank 2. These settings will be perfectly ok for the first flights.

so having the cortex on for a maiden is ok? I have flown the cortex in my 40% BH cub and my 100cc Sbach. I thought you had to trim the fram first then setup the cortex. But I can see setting it up then going on the test flight with the option to use bank one with lower gain, off, or bank 2 with the higher gain.

For a first use of a gyro you would never take off with the gyro active as catastrophic mistakes can happen in setting reversed travel direction and/or too much gain. Get to a safe height then gently increase the gain or switch gyro on, and be prepared for immediate switch off if the plane goes out of control. If you switch on and can wiggle the controls and the plane is in control, you are safe to proceed testing the gain value. If you have a reversed gyro control you would get to know about it in a nano-second!
