I fly scale aerobats and thought that the function looks cool so I tried it. My plane is setup for 3D but I also fly alot of IMAC with it. On IMAC rates, I do no lose any throw, since my elevators can move more than 45 degrees. On 3D rates, I don't lose any throw either since it is the ATV that stops the servo from moving.

Now for the effects in flight, I did not notice any noticable ones, frankly. I used a conservative amount though. Something like 15% or 20%. It SEEMED to make rolls more axial but that must be my imagination... On the other hand, it did not worsen anything so I left it as is. I have flow like this for 2 seasons now and will as is as long as the plane could fly...
