These motors are specifically marketed as 2s motors. I replaced some older betafpv 0802 16000kv motors with these. Direct swap all other hardware and frame the same. One motor burnt out after the 4th 2s pack. I replaced that with one of the older motors. A day later, and 2 packs in, a second motor burnt out. I am not flying any differently, the hardware is identical. These are the first motors I have had that actually get too hot to touch. Motor bolts are not touching, there is no friction from anything else....
I am extremely disappointed to say the least. I do love my cockroach frames and new bee canopy's but I doubt I will pull the trigger on NBD motors in the future.
I was having the back motors heat more than usual on slow indoor flights, but I also had an unbalanced drone, after balancing it and flying outdoors I managed to run packs without overheating the motors
very good performance and punch, the brown color looks better than I thought with the drone and electronics
good option for 2S tiny toothpick builds
