Carbon Fibre Magnetic Prop Balancer
A prop balancer is used to check that your props are balanced an out of balance prop will cause vibration and noise which can then lead to damage to the motor or/and air-frame, by balancing your props you can eliminate this potentially adding more power and thus a longer flight time.
see the video below for the importance of prop balancing.
Please note that due to manufacturing tolerances you might need to balance the actual blue aluminium tapered nuts that hold your propeller on the balancer as they may not be perfectly balanced. This can be easily done with a small metal file. It’s suggested that you perform this step before trying to balance your propellers.
The balancer comes disassembled.
