Unmanned aerial vehicle (uav) with light weight of DC cooling fan will what are the characteristics?

Unmanned aerial vehicle (uav) producers, we will find a light weight, big air volume, price cheap DC fan, to make such a DC fan to have what characteristics? First of all, to be light in weight, or the small size, small volume air volume is small, this is a problem. If the DC fan thickness thin, larger size, the weight will be small, but the material cost is a little high. And the weight of the other, if go to from the characteristics of the materials, with light material, may be the price expensive, or the characteristics of the DC fan has a problem again.
