Steps from 1 to 3 are OK, but when i download firmware.diydrones.com/Tools/Ard … indows.zip and unzip in C: , i change preferences in arduino like in the step 5 but can’t find arducopter, rover, etc… only libraries and tools… done this in different PCs, having the only arduino downloaded in C:, but nothing… it’s frustrating maybe i’m refering to a wrong or old GIT sources?
