// Example config file. Use APM_Config.h.reference and the wiki to find additional defines to setup your plane.
// Once you upload the code, run the factory "reset" to save all config values to EEPROM.
// After reset, use the setup mode to set your radio limits for CH1-4, and to set your flight modes.
