Hi everyone my name is Don. Im an old analogue guy living in a digital world lol. Im the new owner of a Ruko F11 GIM2. Ive flown it two or three times. My problem is i cant get it to record video. Ive put a couple different class 10 SD cards in it, formatted them and thought i was recording video but i wasnt. My Mac book pro says the card (s) are unreadable. I took one card from my gopro and tried to record with it also and no dice. Has anyone else ever had this problem? Im brand new to this . Any help / advice would be greatly appreciated. Thanks.
