It's not "Just a loudspeaker" . . its the light (spot light) VLOS has never been more secure. How many new add-ons do you think there will be that use that TOP port on the
Mavic 2 Zoom. My bet is you will eventually get the mavic with the Top Port. . . besides the Data Encryption and ADS-B feature (see real aircraft in the area approaching from miles away before you hear them) . . all worth that extra $500 . . Now instead of me buying a whole new aircraft I'd bet in 6 months there will be an Infrared Camera Gimbal on top . . is that enough . . or how about a parachute if think it's a danger of hitting anything or possibly getting away from you . . shut it down in the air and go pick it up. It's all coming . . .
If you are in Canada call drdrone.ca . in Halifax . . great service. . . I purchased 6 machines from them last two years . . very knowledgeable folks. ps I'm not a sales or marketing arm for Drdrone . . just a satisfied customer
