Higher than normal sink rate

Post by Mike1 » Sun Jun 26, 2022 9:05 pm

Hi guys, this is Leo from Argentina.
I've been using Condor 2 since 2020 and recently I noticied during online flight that the glider (happend with the Discus and other more) has excessive sink rates a given speeds. I noticied that because on the crtl right vario mode, the netto values varies from -0.3 to -0.4 in still air.
On the XC soar infobox, I can see aprox the same values of negative netto.
I checked gear, airbrakes and autorudder is on.
The following day to the competition, I hosted my own and put still air with thermal markers to avoid it and everything was normal. 0 netto on the glides and any speed.
I sent an email to support, but the answers were vague.
Any help is more than welcome!
Thanks.
PS: on the final glide was even more evident - starting with +20meters at 25km and after 20 km, I was -250meters!.

This issue pops up from time to time.
One possible cause could be very high FPS in online flights.

Search in the forum at the "sink bug", it's often written about it. I have had it too, very frustrating.
