Hunting for target altitude

posted this over at the old forum…

I just flew this 2.75 today and my Penguin is all messed up… RTL used to be smooth, today it was hunting for the target altitude like mad… it was set at 600… it hunted wildly between 450 and 550, speeding up and down, in some crazy pattern. location was ok but altitude was wild… any ideas? I didn’t “re-tune” the plane at all so I didn’t mess with any settings… I was hoping the old stable settings would be fine…
What has happened? I am sad…

Would this bug be something that I just experienced? My plane was very tuned in before… but I am not good with tuning and I sure I hope I don’t have to start again

I had the same issue with 2.76. No answers yet to my tlogs…waiting…
