Change of design due to a technical problem that I never had before.
First flight loss of power…. No change, not even powering it down, second flight no problems. Tried everything from replacing the ESCs to testing the battery voltage with no indication of any errors... In the end I may have solved it now and I still don’t know what it was…
Anyway, still have the old shell but will probably stick with this minimalist design that keeps the air intakes open.
