Hi I for one have tried to use Akira with all my MoVIs - M5, M10 and M15. I consider myself an expert in tuning and balancing the MoVIs. Akira has at least two issues in my opinion: In handheld mode there is clear roll drift that occurs every now and then. Another issue is that the autotune that worked great on 4.02 at 70% on airborne mode and the drone suspended does not work at all with Akira. Nothing physical is altered on the Movi / drone / dampening but with 70% and even 60% autotune I get very bad jitter when flying with Akira. I am not alone. At least in Finland where I live all the rental houses still use the 4.02 fw on their MoVIs because it works better and is more reliable. To the point that one 1st camera assistant made sure when I sub rented my M15 to a rental house that my MoVI had the "older" firmware. Why complain when 4.02 is good? Because I would like to use the new features and "better stabilisation" Akira offers. As Freefly has moved on with MoVI Pro I´m afraid Akira will be the final firmware for the old triplet of MoVIs. I hope not as the price of the three MoVIs combined with all the upragdes to M10 is well over 20.000 USD. Closer to 30. With this kind of price in my opinion the end user has a right to expect that the firmware is perfected and early adopters supported. That way they will remain customers. Is everyone else completely happy with Akira?!
