I will briefly interrupt my wailing and gnashing of teeth here to inform fellow Litchi users that I have finally seen confirmation from the horse’s mouth, as it were, that the upcoming SDK for the Mini 3 will NOT include any provision for the storage of all waypoint GPS coordinates on board the drone.
Official DJI spokesman Mr. William Wong delivered this utterly depressing news at the DJI SDK forum, and I have no reason to doubt the accuracy of his statement. I profoundly regret now having bought a new Mini 3 without first determining with absolute certainty that beyond RC signal missions would in fact be possible as they are for the older Mavics 1 and 2.
If you were thinking of buying a Mini 3 to fly fully autonomous Litchi flights, let me warn you to avoid making the mistake that I just did, in rushing to buy a Mini 3 after being seduced by that 45-minute flight time specification. Here is a link to DJI’s SDK forum where I finally learned about this truly sad reality.
