Hi, I have flown my I1 since february with X3 without issues. I am on the latest I1 (non-pro) fw v. 188.8.131.52. Now I bought the X5 and have a question about how to proper update it . I will continue to use both X3 and X5 cams on the I1 (non-pro). Which fw should I install now? I have seen so many users having their I1 fly very slow after updating to the I1-Pro fw (maybe because it flashes the ESC's to accommodate the slightly more powerful I1-Pro motors). But is updating to I1 Pro fw the only - and correct - way to start using my X5 on the standard I1? Thanks.
