I have the GT8. Some people hates it becuase of reverb defualt setting from the factory.
All you have to do is adjust the world Equalizer or change reverb types on the factory's default setting.
The thing about the GT8 is...It's has perimeters up the wazoo. I spent a month just trying to
understand how to navigate it , through all of the menu or options. I still havn't use this processor to it's full
protential becuase of the freedom. It's insane compair to the stomper boxes I had. The stomper did the job
but I had to re set it everytime manully over and over again to achive dfferent sounds I wanted.
I only wrote 5 patches for the darn thing. It's a good thing there's
patches up the wazzo avaliable for down load.

I'm set for another couple of years for my noise making fun.
$500 to get it out the door.lol The GT10 just came out.lol
The G4 is like that.
You can adjust the servo speed on top of the expos. Even gyro types and gain of the gyro.
I can adjust it to simulate my own real heli closer than the defualt settings.
Since I didn't spent boo koo bucks on my tail rotor servo, the tail drifts a little bit.
In other words it's not perfectly tuned. None of models are perfectly tuned. I try to dial them in as best I can.
I want a simulator to simulate my models...not someone else's models or inturputation of what a perticular
should fly like. We use different equipment, engines ,props, servos...ect
