Here are some pictures of my WIP Autarch on foot/jetbike. I have magnetized his headslot, the right arm and the torso so that I can equip him with different weapons or put him on a jetbike whenever I want to field him that way. I magnetised the head so that I could swap between autarch head and farseer so that I can decide if I want another Farseer on jetbike or Autarch. Like this post says, its all work in progress!
To the left of my WIP Autarch is the first Autarch finished, converted only slightly. His right arm is magnetized so weapon swaps are possible.
Wielding a firepike from the older 4th ed (not oldest) fire dragon Exarch which I will be using as a stylised fusion gun in my games.
This is when mounted on the jetbike. I´ve decided not to go crazy with convertions on the jetbike, I want it to look as simple as possible so that I can alter between both using it as an Autarch jetbike and a Farseer jetbike and possibly even a warlock jetbike.
