I have mistakenly bought a Eachine EX2H drone without the camera. I did not know that until too late and I could not back out of the purchase. It was an auction bid at eBay and I paid C$90 for it. My questions : 1. Is it hard to install a camera, or is it just screw the bracket and plug in to connect? 2. I googled but failed because I don't know how to search for a camera compatible with Eachine EX2H drone. Need a link to the source. Please.
