Ah... yes... I see what you mean. Yes those are tiny brushes used for glue applications and what not.

Have you painted a model before? If not, it would be good to get a basic set of paint brushes for models. I don't know what sort of thing you have in the US, but most model paint companies make their own.

As an example - I'm not suggesting you buy these, just something similar - these are the brushes made by Humbrol here in the UK. Personally, for the Chinook, I'd start with a pack of flat brushes and a pack of detail ones and see how you get on.

Humbrol Brushes.
