Using the standard digital avionics and the PMS50, two different GPS courses are displayed. Totally strange. The systems don't seem to be integrated. Activating SAS, NAV and ALT does not work either. It holds the altitude but does not follow the gps course.
Not even close to default. Thanks though. Check your assitance settings. Sounds like it's on to me.
No, it is off.

Ola amigos tudo joia. Comprei este produto e achei muito bom. Só tem um poblema que não consigo resolver( o botão do SAS e demais não funcionam ) porque motivo não esta simulado? O manual só vem para XPLANE e nãofunciona no MSFS 2020.

I love this aircraft, great to fly and very realistic. Two questions however; is the heli sas going to be added in a future update and also is there going to be a glass cockpit update in the future. On a separate note are you planning on making any Robinson helicopters. I think there would be a great markup for them.

Good product, flight dynamics are comparable to a DCS product which I have not found in MSFS2020 yet, including with the 500E Cowan also offers. My only significant gripe is with visibility in the cockpit, the structure on the interior feel too wide, cutting visibility. Having been in a real AS350, it has far more visibility than this. Hopefully we can get sling loading soon, would add the dimension this needs. Overall, great product.
