Easy Prop Balancing
Here's the quick and easy way to balance cheap plastic props. With larger props it makes sense to use a magnetic prop balancer, but this seems to work just as well.
Start with a prop, and a screwdriver that's just about fills the shaft hole, but doesn't rub. The prop should swing freely, but not wobble too much.
Hold the prop level, and then push one side down, then the other. If the prop is balanced, there will be no tendency for the prop to move. If your prop is out of balance, one side will tend to sink lower because it is heavier.
Put a piece of scotch tape on the back of the heavy side. You don't need much. Check for balance again, and keep adding tape until the prop maintains a stable horizontal position.
Here's about how much tape I usually need. Taping closer to the outside gives a stronger counterbalance.
