Here RoadKill, while working on my DMR, I made this specifically for you, but i feel it will help other people as well. Ill take a look at your model if you want me to, but this should explain how to fix a lot of the problems.
Make sure you watch it in HD cuz you can see the little details better!
oh well this was the best i could do, it was hard to figure out where to connect each line so sorry about the red lines but here is the pep link not unfolded
