0 functionality with just gps and APM? Posted by Brandon on February 2, 2012 at 1:03pm What kind of functionality do I get with just the GPS and APM? I know I can't do auto land without sonar, but what else can I do or can't do with this setup? You need to be a member of diydrones to add comments! Join diydrones Email me when people reply – Follow

Sonar is optional. It's only used for low level ranging and only if it is enabled.
