Align Trex 550 elf v1 w/Align Ds620 rudder delay and common

[Alyon187]

Im working on a fellow helifreak bird so that he can start flying it. Hes still pretty new and hasn't got setting up helis down yet. Anyways im finishing up the setup process and would like to see some ideas for rudder delay and common gain settings. On my G500 I use common gain of 1.1 @ 81% so I thought 1.2 @65% would be a good starting point for tail tuning. Since ive only used bk servos on both of my spirit equipped helis setting the delay to 0 was recommended but def not for the align ds620. So any ideas of where to start these two parameters?

Values from the Setup Wizard for T-Rex 550 will be fine.
Rudder Delay should be between 5 - 10
Piro Consistency approx. 160
Rudder Common Gain: 1.0x
