So it occured to me that the spinning blades of the deff-kopta`s would prove to much for and Ork who would inevitably try and kill something with them and as they are on top this would lead to a messy out come for Pilot and anything else involved be it guardsmen,
SM`s, walls, other orks the list goes on . . .
Anyway i thought wouldnt the Orks prefer to streak across the sky on a jet
if anything any subsequent impact would be at least more spectacular
so i took a Black reach deff-kopta and turned it into a Jetbike
