I can not afford the thermal version of the Mavics - today. I am asking if there are limitations on these drones that would prevent me from adding various different cameras, to include a thermal, down the road. I am seeing zoom cameras in different models, but want to pick and choose what kind of camera I want to run and add it on the drone. What do I need to purchase in addition to the Mavic Drone to allow me to do this? Thanks CDS
