Damper and link balancer

After gotten some inspiration from an rc forum I made this, it's a tool to help you get the links and shocks for your rc car just right.
For links just mount them in the device and the anglethingie shows how close or far from having them the right length.
If you want to check your skock mount them in the device and push down on the slider, if there are any difference in springrate the anglethingie will move towards the side with the softer spring. This device have been tested with soft crawler
