Hi, is it possible to perform firmware updates on F09-S? I am asking you that because I bought one a month ago from a store at Aliexpress. I believe it's arriving this week. I have watched a video from Alishmao where he said he has sent his F09-S back to factory to get a new update. The new update allows the heli to fly inverted and it also has some hover flight improvements. I look forward to hearing from you soon.
