So I figured out a way to relieve the stress on the gun and make it not so top heavy. Part of the problem was where the gun connects, there are only 2 connection pieces, and as the gun is pretty heavy, they can't really take the stress and that's why a lot of people are complaining about the gun tilting downwards at a certain angle when they go to put the gun in siege mode.
I figured out that if you added a third connection piece, it's able to take more of the stress and you can pose the gun without it tilting when you have it at a certain angle. And I also made a holding claw, like the ones you see on modern day self propelled artillery, for the barrel so that it doesn't jiggle when you roll the vehicle around. (I took a few pics, but wasn't able to submit them.)
What have you done to modify the Kodiak?
