Thanks for clearing that up guys. I'm going to pick up a triwing tomorrow and do a bit of maintenance.
Update: Popped open my DS today. Just tested everything out and everything seems to be working. Thanks for the guide.
Another Update: Just noticed this while charging up the battery...
I'm looking at this guide before deciding whether it's worth it to break down my DS to clean it up a bit, but I can't quite tell the difference between the two photos in step 34.
