Weight: Front 13.28 grams each, Rear 13.49 grams each, 53.54 grams total. Mini 2 = 237 grams so only 290.54 grams with protection. There are no instructions but it is easy to understand because they fit my Mini 2 perfectly when they are correct. Notice that they are labeled A, A-1 and B, B-1 in the fourth picture. From top to bottom, B is front right and B-1 is front left. And A is right back with A-1 left back. It seems to fly well with them (and I added the chassis and hood at the same time).
