Great 0802 Alternative
"I had been running 0802.4 19500k/v's and I wanted to switch to something with ball bearings and 1.5mm shaft for durability because I was having to replace the 0802.4's fairly often for being inefficient after moderate crashes. These motors, despite being slightly heavier, use less current at a hover, feel just as responsive as the higher k/v motors did, and have more torque. My 30g ducted 40mm whoop with 2-blade props flies around 5 minutes with a 550mAh. I've wrecked them a few times now and so far they're still good as new!"
