I downloaded version 3.0 from the UK site.it works fine. It is complicated to start each time.I have to the many steps in the user manual exactly. I own a Blade Chroma , but I think it is basically a Q500 in a Blade body. I want to practice flying in manual mode,and it is very good for that. On the sim the quad still seems to have altitude hold, I was wondering if anybody knows if this actually happens, as I have never tried my quad in manual mode.
