modelguy designs and builds wind tunnel models as a second career. First career was aerospace engineer. Current project is a Terramite tc4 in bad shape. So far I have cut new keyways in the pump shaft rebuilt one hydraulic cylinder and straighteded the shaft, redone the fuel tank and learned how to make the Deutz diesel run. Still have a few rusty hosed to replace and get it to charge the battery. Then I can see if it will tackle this hard GA claly.
