1/24 Crawler Course - Weighted Bridge

After several attempts with different pulley setups and locations, I finally got this bridge to work 100% every time. As you can see the overall project isn’t finished.
Easy to say I’ve been bit by the crawler bug. Less than a month ago I bought the TRX4 Blazer but it’s too big, and now too dirty, to play indoors so I got the Element Enduo24 to scratch an itch. I’ve watched a bunch of videos with indoor courses/setups...now my addiction is getting worse!
