RotorBuilds is a new application that allows multirotor DIYers to price out their build and share the finished product with others.  As you add each part to your build the total price is updated in real time to give you an idea of your total build cost before and after completion.  It offers an extensive social foundation that allows users to discuss builds, talk privately, "like" builds and follow updates from one another.  Ask questions and offer updates about your build to get valuable feedback from the community!
