This is just like buying a ccw, had bought a product to replace the traditional propeller (9x4.4inch).
9x4.4inch products failed to raise drones mothayeo have enough thrust.
It is not sure that there is sufficient thrust.
Mounted on drones I think I know Do the experiment.
After all, it is satisfied that the purchase prices.
Performance of the product should try for a later application.
I wonder itneunjido have thrust much.
Perhaps have a satisfactory level of thrust is, we must find a way to offset the drones probably will not.Good propellers nice brice but not stong. But very good for beginners.Ordered 2, no spacers. So it's unusable !
Otherwise, the props are not bad but unballanced.The props are deliverd without spacers! Because I don't want to throw them in the trashcan I filled te space up with epoxy. Then I drilled the hole. Takes time to do, but it works just fine!
