For some of the repair services we perform on RC electronics, we have to reference or steal parts from dead/unusable units of the electronic component in question.  Many ESCs and chargers have been saved from becoming paperweights by using components from other dead units.  In addition, functional units can be created by combining parts from different dead units and made available to you at a hefty discount from retail.  If you'd like to help contribute to this cause and keep RC electronics out of the landfill, you can mail them to the following address:
