I installed an S8 (same as S80 only 57mm) last Friday and flew a first flight on Saturday. I really like the display. (I have previously flown with its sister V8 in another glider.)

There are many important settings to make. Paul Remde at Cumulus Soaring did the initial / basic setup. I then set more settings to my preferences. I found a couple I missed so will fix them before next flight.

I have the S8 connected to a FLARM and Oudie 2. I will use the S8 as the primary vario, as a FLARM display, and as backup navigation. I probably won't use the task function much as I really like the Oudie2 for that purpose.

Just my $0.02. I hope this helps.
