beachbrada, does your model list the control surface deflection in degrees, or does it list a distance the surfaces need to move?
The aero works meter is a degree meter and the GP is a distance meter.
I have the GP meter and it works ok. Sometimes it is hard to get it to stay in place when it's clamped to a thick wing.
Easy enough to convert degrees into distance. Open the calculator program on your computer, usually under accessories. Hit view and select "scientific". Enter the number of degrees into the number pad and then hit the button labeled "sin". Multiply the answer that the calculator gives you by the control surface's chord in inches or millimeters. The answer is the control deflection in inches or millimeters.
