I recently made a tutorial on my channel for the 1:1 scale version of the C709 Longsword, the giant fighter-bomber featured in Halo: Combat Evolved. I made a 1:1 scale version of the C712 Longsword (from Halo 2/3/R) which was tiny compared to the original model. So I've taken a shot at building the C712 Longsword in 2:1 scale. Here it is.
