This small hardware upgrade adds 4G/LTE connectivity to any Yuneec H520 drone in market today. It's "Remote Team Mode" allows professional teams to have an operator in the field and a person with domain knowledge in the office; controlling gimbal & camera.
I presented this product at the AUVSI XPONENTIAL drone exhibition in Chicago two weeks ago. We've received many praising comments from industry veterans, Yuneec executives, commercial clients, distributors and consumers as well as from decision makers in the military, defense and first responder / search and rescue fields.
From an engineering point of view, it looks like it seamlessly fits onto the drone.
Pros:User-installable? That's very good!
Cons:Not sure. Seems to be the only product in this price point.
