Would anyone care to comment on their experience with the LXNAV S80 vario? Pro's, con's, likes, dislikes, does it perform per manual specs, etc? On paper it looks like a very nice instrument. Thanks for any feedback.

I have about 40h with the S80 now in my LS7. My setup is as follows:

PowerFlarm Core Pure - S80 - RasberryPI with USB Serial and Wifi AP - Blackberry Passport with XCSoar


Highlights:
* Very good display
* Very good task function (tested in competition)
* Powerflarm can be powered directly from GPS port
* PDA Port with Power (5v/1A)
* Accurate Wind
* Flarm Display integrated (i threw out the led display)
* Task/Waypoint overview
* STF mode great for Finalglide
* Protocol PDA is the same as for the V7 (S7)
* Easy Firmware upgrades

What it (currently) doesn't do:
* Nearest Airports (This i miss...)
* IGC Logging (I do it via the powerflarm. USB Sticks are very comfortable)
* AAT Task Time optimization (It does AAT just no optimization)
* Airspace warnings (This i miss...)
* Spoken Flarm alerts (I was under the impression it should)

Things I'm still working out:
* Polar calculation does not match XCSoar's which is a shame for Auto MC
* The PTOT Probe in my unit seems defective. I have no TAS
* Using the digial IO pins for the water valves
