When people have an issue that does not resolve after reading and following published instructions their first course of action should be to contact the customer service department of the company that made the product. For some reason they\we run to forums such as this one thinking our questions will be answered and resolved by system experts. Posting in places like this is good for general conversational purposes but the fact is, if you have followed directions to the letter the only fix you will obtain is with customer service.
Unfortunatly customer service has the same answer. "We know there were a lot of people who weren't happy with the beta firmware, but the official release is out now, and seems to have fixed most of the issues people were complaining about online. "
The issues are still there and they know it but either don't know how or don't care to fix them.
I do understand that we are dealing with a hobby level aircraft that was awarded the term "consumer drone" as a means to promote greater sales volume. In truth every MultiRotor priced less than $10k is hobby level because none of the components used to assemble them are in any way certified, have zero published documentation referencing min/max performance levels, are made by the lowest bidder, and assembled by companies with no AS9100 policies. Many of the components used may be faulty and only discovered after they have been in an operational state for an unknown period of time. This is applicable to all hobby/"consumer" drone manufacturers. We are not buying a certified aircraft and should not be under some illusion that we are but we should be able to expect known issues to be fixed in a timely manner but they are not. Over one year to come up with firmware that still has known issues admitted by Autel staff is unacceptable.
