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). I change the settings to payload mode, but shortly after launch the app still shows a message saying something along the lines of "Propeller fuses detected, shutdown (or low power response) activated". Slow hit him against some walls and stuff and he just kept flying like nothing happened so mission accomplished.
