Ali you have contribute loads to our hobby and you should be the last guy to use the word "sorry".Your help to modellers around the world for years is priceless.
So that iGyro 3e was not defect then.
Cortex dealer should thought of this too.Thats why he didn't try to sell you the cortex but offered you a trade.I dont trade good stuff for junk
For your information we had a similar experience with a very sensitive aileron gain over here.
What we discovered was that the setup of the link geometry was bad enough to kill the resolution of the servo.
For custom gain demands on each channel powerbox offers the usb interface that allows you further programming to fine tune your iGyro 3e

Too bad Ali was busy…once you experience the superior smoothness of the iGyro 3e you will bin any Cortex.Thats what my mate did on his Viper.
