Default Balancing a 30mm true turn spinner

Does a quality tutorial exist for balancing a small electric True Turn spinner that is intended to be used on a 30K plus motor? Thanks all

No substitute for good ol' trial and error with weights. It is amazing how out of balance some spinners are, especially being the expensive ones that one would think are balanced. I've spent hours balancing spinners. You could set it up on a prop balancer, but there is no easy way to indicate if the weight should be added at the base, or toward the tip. With longer cones, find the spot/weight that smoothens the spinner, and then see if it will further smoothen by moving the weight outward and adding/removing weight.

One thing that is often overlooked is the relation of the motor internals to the prop/spinner, when it comes to balancing. I've managed to perfectly smoothen out props and fans by simply rotating the prop/spinner or fan/adapter in small increments, until you find the sweet spot.

Trueturn spinners are factory balanced - and they really do it.

No need for you to spend time on when you could be flying
