Back in the early 1990s, Italian Fred Marcarini build some wonderful CSM conversions, including assault marines using 2nd Edition Ork Stormboy metal jump packs (refer (White Dwarf Issue 1999, page 31) These jump packs were huge, giving the models a bulky aesthetic, particularly compared to the clean-lined and compact Loyalist Space Marine type.
The 40k Lore position that the technology during the Horus Heresy was generally more advanced than in the 41st Millennium, jump packs used in the 31st Millennium would be more compact (and capable) than what is available now. From this, it could be assumed that the jump packs used by original members of the Traitor Legions in the 41st Millennium would therefore be more compact, and this can be seen in the current Raptor/Warp Talon models.
However, I find the current Chaos jump packs to be, frankly, rather dainty, even with the fins on the side (for some reason, I think ‘butterfly’ when I see jump packs with those fins). The 4th Edition Raptor jump packs are bulkier than the Loyalist version, and I think they represent the Chaos aesthetic better than the current ones. While Chaos Raptors are highly skilled in flying/jumping, to the extent it has changed their very nature, I wanted my models to echo more Orkish brutality than Eldar elegance.
To that end, some of these Raptors have honking jump packs built from Ork rokkit packs, generally to test this approach (I’m thinking they look too bulky). Khorne Berserker and Loyalist Assault Marine legs are used to give the impression of movement and fluidity without the ‘daintiness’ of the current Raptor legs.
