C-17 has the blue engines with no fan blades and also has no spoiler animations even though they added every other animation
On the AC 130 the gun barrels are missing And there is some pink stuff on the windows and stuff
This issue was known in the beta including the blue engines on some other aircraft and the pink thing was also found on the A350 and 757, as I said this is a known issue and will be fixed in the further update.
As @ECOFRIENDLY_TIME has already eluded to, you can expect this to be fixed in a future update assuming a patch hot fix isn’t released before then.
The C17 is honestly the worst model in the sim, its horrendously outdated and needs a serious rebuild.you can vote for such an update in the features category, or by following this link.
