Flying space gnolls!

One of the unit types in Grimdark Future's "jackals" army list is vultures - canine beastmen equipped with jump packs. Gnolls, of course, are feliform rather than canine, but they have impeccable scavenger credentials. 

 I used space-marine backpacks with space-marine shoulder pads over the exhausts to create the appearance of mobile-jointed jets. The weapon arms come from all over the place.
