First time using FBL - on anything.
First time using 3GX - any version.

Using 3GX on my Trex 450 Pro, upgraded to 2.0
Went through the "non-PC" setup procedure with no problems.
Now, I have a flying - and stable - helicopter.
It flys okay - but nothing spectacular. I think it flew better as FB'ed.

The question - What do the settings in the "Flight Mode Parameter 1", "Flight mode parameter 2" & "Rudder parameters" really mean?

EG: If I adjust my "Flight mode parameter 1" "Aileron roll rate adjustment" to 70%, the "Movement Speed" shows 300 (degrees per second?). But, if I increase it to 80%, the Roll Rate is still at 300. It is like 70% is the max

I'm not getting the "pop" I expected.
EG: I set the collective to +/- 13 degrees (per the instructions) and the first time I did a full negative pitch decent (while upright), I almost couldn't pull out - I had to jamb full positive collective to transition back to a positive climb.

Did you measure collective and cyclic throws with a pitch gauge while in DIR mode? I setup my 500 using V2.0 software and a pitch gauge and it's crazy fast. I left almost all the settings of the 3GX stock, I did move a couple of them a little bit but not a lot. I don't remeber which once I moved but I'd bet it'll fly great with the factory settings. Just check to make sure your cyclic and collective are what you are expecting with a pitch gauge.

Yes - I use the RC Logger pitch gauge.
I followed the setup, but now I am not happy with the roll or flip rate.

I have 2900 RPM on the main, and when I was using FB'ed, it reacted much quicker.
