Balancing large carbon props for quadcopters and multicopters

Balancing larger carbon fibre hubless props for quadcopters and hexacopters has particular problems and challenges due to the long chord length. In this video, I explain the techniques I use to balance these props as accurately as possible to eliminate vibrations.
The trick is to take your time and go slowly, checking the balance often. Always remove material from the underside of the prop and stay clear of the leading an trailing edges.
