Re: [Flightgear-devel] Toe brakes not working - 172

[Ron H. <gs6...@gm...>]

Thanks Dany,

Pointed me in the right direction. I had to both set the factor to inverted
via the dialog and manually set the offset to -1.  Kept defaulting to +1.
Now the toe brakes work properly.  Had dive into the fgcommand code to
understand what was happening.  All is well now. And I learned a bit more.
:)
