I trusted Alt Hold, in my case it worked always fine, within 1 m in calm conditions.
This morning, calm condition I tried to get ready for another Loiter test.
Just checking Alt Hold at about 5m worked very well until all of a sudden the heli dropped to the ground.
I couldn’t interfere anymore, one reason, in Alt Hold the collective is more or less locked, and there is not much you can do with the stick. That’s a bit of a disadvantage; I know it worked in earlier software versions.
It shattered my confidence quite a bit, because I don’t know what caused that glitch.
Alt Error just dropped for no reason. There was no change in Alt before the glitch.
May be someone has an idea?
