The Autel Max 4T doesn't come with the RTK modules necessary for safe and secure use in signal compromised locations. They are an extra cost option.
Also, many people don't understand that you need 2 modules onboard in order to allow precise 3D positioning using a base station which then allows the drone to fly without input from it's magnetic compass or even barometric elevation.
One RTK module is fine for precise mapping, but it can't protect your drone in areas of magnetic interference.
The new price reductions on the Matrice 30 series are welcome of course, and they are still an excellent buy and have greater capabilities out of the box than the Autel models.
