Usage in a drone?

[jetdev1]

I haven't really looked up the numbers, but do you think this aerospike fan can have a higher thrust to weight ratio than a conventional propellor in a quad copter drone? I don't really know the figures, but if the mass flow rate is comparable to a conventional prop while having a significantly higher exhaust velocity, would it be possible that this can compensate for its additional weight and have a overall higher thrust to weight ratio?
