Can't be jammed, smaller frame to shoot at, more possibilities to spy from, if it falls better chances to get up by itself. This might be a better alternative to drones actually.

More vulnerable to chemical (anti-pixie spray) and biological (swarm of bees) weapons, may panic, may desert, may be captured, slower than a modern drone (they can reach up to 500 km/h iirc). I think pixies are better for recon while drones are still more suitable for a combat.

How would you deploy those? Or store them? I don't think this would really bee an issue.
