What steps will reproduce the problem?
1. Pitch the gimbal towards the floor and pitch points above horizon a few 
degrees
2. Ptich the gimbal towards the sky and the camera points below the horizon
3.

What is the expected output? What do you see instead?
I see the Chart function showing values that I would expect it to correct for.  
When I pitch the entire gimbal towards the floor (exercising the pitch function 
about 45 degrees) I get numbers on the chart of -7.00 then it starts to settle 
back down slowly to about 2..

When I point the gimbal down 45 degrees the chart function shows about 10 
degrees and does not really correct for it.

What version of the product are you using? On what operating system?
version 48

Please provide any additional information below.
I am using a 3s lipo with flight  14 pole GBM3508 motors.
My settings are as follows
Iacc=0.1
P=15.0
D=2.0
Poles=14
max PWM=100
Rcmin -45
Rcmax 45
