Hi Ron,

Do you mean 0.05 or 0.5? I understand 0.5.

In FG, the brakes expect 0 to +1.

Your rudder pedals sends -1 to +1 for the brakes (js_demo).
hence, you need an offset = +1 to start from 0.
But it gives total amplitude = 2 (0 to 2). Hence the 0.5 factor to go 
from 0 to 1.

See FG Wiki Bindings property-scale
http://wiki.flightgear.org/Bindings#property-scale.

Mind the ordering: I always see offset before factor. I don't know if 
that's important.

See the Saitek xml file in 
fgdata/Input/Joysticks/Saitek/Pro-Flight-Rudder-Pedals.xml.

Your customized or personal joystick xml files should preferably be put 
and saved in (for Ubuntu) .fgfs/Input/Joysticks. Here, they will not be 
deleted by FG updatings.
