If you're seeing non-zero roll, you'll need to correct that in the mount. There's no adjustment for that. If it's pitch where you're seeing issue, use SETUP > PITADJ to get the zero pitch value correct.
hi,
i tried to adjust it by adjust remote compass module but nothing happend (heading was moving but not roll ), do i need to adjust mount EFIS-D60 itself or something is wrong with the remote compass?
EFIS-D60 looks like doesnt have any room for adjust
Just an observation here -- with aircraft that have 'curved' panels, ie Jabiru & Lightning etc I usually make sure the wings are level first (digital level & wing jacks) then make a level line on the panel for a reference point.
