Building a Quadcopter p.5 - First flight and other Info
In this tutorial, we'll wrap up the building of a basic quadcopter, fly it, and talk about a few more important things. First, we need to talk about propellers.

There are two major types of propellelers. Some are threaded, some arent. If your motor's shaft isn't threaded, then you cannot use the threaded propellers.
Threaded propellers are usually both the propeller and attachment system all in one. This is nice for quickly attaching and detatching the propellers, but it does not allow for you to balance the propeller. Almost no propellers come perfectly balanced, so you can safely assume the quick detatch ones are not perfect either. Despite this, I have had no issues personally with adjusting for differences in balance by modifying trim on the controller. If you can, then you can balance a propeller by adding tiny bits of tape to the underside of the propeller to add weight, and you use a propeller balancer.
