Hi fellow aviators! New to this hobby and was after a quick answer! I've got the P3P and am looking at putting a larger SD card in it! I updated the RC, Copter and Battery with the latest firmware when I bought it; however should I change my SD card will the original firmware be there? Might sound a stupid question but I wasn't sure if the update was stored on the SD card or internally within the devices! Would appreciate some advice! Many Thanks.
