So I have a dilemma, I have iosd Mini, Datalink, FPV, Cloverleaf, Polarpro filter and a Quarter and a nickel. I fly with the new version which is pretty slow to fly. Descents is slow which is fine with me but once I get below 20 feet it keeps falling, Then I try to thrust up and it takes about 20 seconds before it responds. Can I use V1.8? I don't mind losing GS for a bit till I need it, then I can upgrade when I need it. Also if I can, what are the procedures on downgrading? I downloaded V1.8 but not even sure what I need to do. Thanks in advance.
