It's a myth that some props don't require balancing; all props regardless of the brand must be balanced to a greater or lesser extent. It's especially important to balance props for multirotor use. Multicotper flight electronics and particularly the accelerometer within flight controllers are very sensitive to vibrations. Excessive vibration can results in very bad performance, in the worse case rendering the craft unflyable.
This virtually frictionless balancer uses precision-machined aluminium rotating wheels, self-centering locking cones and a hardened grounded shaft to give pinpoint accuracy when balancing your propellers.
It will balance model airplane props of all sizes and weights, boat props, spinners, car wheels, helicopter rotor heads, jet fans, fly wheels, etc. Each balancer comes complete with easy to follow assembly and prop balancing instructions.
With prop balancers you get what you pay for, many cheaper balancers come with shafts and cones that are out of balance and aren't true running making them unusable.
Assembly required instructions included.

How to balance your props: Balancing your props is a necessity. If your rotors are not balanced, one blade will be heavier than the other which will cause an excessive amount of vibration. This vibration will lead to extra wear on motors and bearings, make sensors less accurate at the detriment of flight performance, and make getting good video almost impossible.
The general principle of prop balancing is to determine the “heavy side” of the propeller and then to either remove material from the heavy side, or add weight to the light side. A prop is truly balanced if it can be stopped and will remain stationary in any position.
Method 1: Lightly sand the backside of the heavier blade with fine sandpaper. Recheck often to avoid removing too much material. Removing material at the very end of the heavy blade will have maximum impact, and avoid changing the airfoil shape.
Method 2: Apply a drop of medium CA to the backside of the light blade and use a piece of waxed paper or a plastic bag over your finger to smooth the CA into a thin film. Cure the CA with a light spray of accelerator. Re-check the balance. Apply more CA in thin layers until the propeller is balanced. NOTE: Before adding glue to a prop, make sure it is absolutely clean and free of any oil residue.
If the prop comes to rest in a level position, but is still obviously out of balance (this is indicated by a repetitive seesaw motion around the y axis or the prop dropping to one side after placing the prop vertically) you may need to add weight to the lighter side of the hub. Do not remove material from the hub. This could weaken the prop, making it unsafe.
