I’ll tell you something would really be nice on the next Phantom model. One would be where a person could change the camera out for any number of devices. Develop an SDK with standard I/O calls so as long as a company could manufacture a device that uses those same I/O calls, it could easily plug in and all work from one standard remote. This of course would be a removable camera assembly. Pop off the camera and pop on a FLIR with an optional water flotation device so you can easily convert the same drone you took real estate photos with earlier that day to a device to a first responder drone that can look for, locate and communicate GPS coordinates back, and drop flotation devices to people trapped in water, snow, ice, whatever. Have another package ready for the drone that would perform atmospheric tests on air quality, ozone, etc. You options would be limitless. But the key is that DJI needs to develop a cost effective drone with the removable gimbal and also make that interface where the gimbal attaches where it uses a specific set of commands from the remote and/or the DJI Go 4 app or whatever standalone app a person or company needs to write.
The other thing I would personally love to see is a drone that is waterproof not water resistant, waterproof. I am not looking to develop an underwater drone here, though it could be done, no, I can see people using drones in bad weather like rain, snow, for inspections for leaks on roofs to issues on bridges and highways. If there is an accident and the drone drops in the water, then you hop in a boat and go get the drone back. No muss, no fuss. Lol. Just my thoughts on this.
