@RedJak: i no longer posses the file, i can't seem to find it anymore... sorry. But we will see a new version of that in CE:A and it will be built again.
@Arioch: I had some in the works but am no longer capable of completing the files at this time.
Ok, now this decision wasn't made lightly, it was made over a few days of thought. I made a decision to leave the 405th and other forums at this time because i cant keep everything going at once. Right now i have way too much school and hours at work to be available to make models anymore and spending two months on models would be unfair to the community. So at this time i'm leaving the 405th and deviantart and the deadline for return i come back is September,1 2012, by this time i should be done and will have plenty of free time to model away replicas for your enjoyment. I will also have updated my hardware and have some new tricks when i come back.
The current files i have under work are the Halo 4 Helm, Arrow Flyer and Pelican/Longsword Flyer. The 4 helm will Not be completed because i have since scrapped it and started to rebuild after i saw the video by Blue Realm and noticed some major flaws and the helmet is nowhere near the state it needs to be at this time. However the Pepakura Gliders will be posted and I'm testing the Avro Arrow glider right now since i managed to buy some Ink on sale lol.
I'm sorry the Halo 4 helmet wont be completed but i am aware that one file already exists and its a great model that would serve you very well, I'm not sure of the modellers name but go see if you can find it.
If anyone needs to contact me about my posted models or just has any questions, my email is ForgedReclaimer@hotmail.com and i will answer any you may have. Additionally i will be back no matter what before Halo 4's launch and i will make some models with the new info by than.
