It can make hovers extremely easy depending on how you set it up. When set up properly, you should not feel it fighting you on anything. If you have the gains very strong, it can tame some of the more violent maneuvers. For example, it can slow down the spin rate on a pop top so that you get less rotations. I have mine set up on a 3 way switch so that I can turn it off, on with low gain, or on with high gain. I typically fly with low gain and it gives me just enough "support" to smooth out my flying tremendously without dampening anything. If the wind is really high, I will use High gain and just flip the gyro off momentarily to do a pop top...
The thing that makes this special is that you can adjust:
----the individual gain on all three axis as well as an overall gain
----The stick priority on each individual axis. This means that the gyro will be strong when there is no stick input, but as you input stick movements, the gyro becomes weaker and weaker as you move the sticks further from center
---- The Latching on each individual axis. Latching means that if you do a snap roll and bang the sticks in the corners to do it, as soon as you let go of the sticks and they move to center the gyro becomes strong again and jerks the plane back into its control. With the adjustable latching you can set this feature so that the plane does no fight you or loo weird as the gyro grabs control again.
It really is amazing how well and how INVISIBLE this thing works when you set it up so that it is tailored to your plane and flying style. Heck, it is amazing how well it works right out of the box with no special programing at all! What' more, the firmware is extremely easy to update, and Demon Aero is constantly tweaking the programming to improve the product you already bought!
