Balancing

Some Airfix models require balancing, such as aircraft with tricycle undercarriages. If you have a model that needs balancing, you can simply add a small metal weight to the model during construction. The best place to buy these small metal weights are often fishing stores, however, be sure to use a weight that is not made out of lead.

The instructions should make it clear when a weight is needed, but be sure to leave that section open so the weight can be inserted.
