I second that. I don’t get great life from the boldclash ones but the mmw motors are made by chaoli and are much better quality. I too had amazing lifespan from mmw. It’s a hard call. If you’re crashing alot on a boss you risk popped caps and bent shafts. That could be an argument for using boldclash cause you could kill them before they die on their own. On the other hand … if you’ve gotten into a groove and defy gravity like an aerobatic superhero - and you are flying boldclash motors till they fail on you … it’s time to go mmw and save in the long run.
For a whoop - id say go mmw. The motors are pretty well protected and it’s likely you’ll get your money’s worth from the longer lifespan.
