Choosing Model Airplane Propellers

Good news, you don't have to be an aeronautical engineer to determine the right model airplane propeller for your airplane! In fact, you may be relieved to know that there is no right answer when it comes to the correct propeller for your plane.

As the pilot, you must choose a propeller that makes your airplane look and fly how you want it to. After all, everyone has their own flying style. Whether you're flying electric or gas, the concept is the same.

You my friend, are about to become an expert on model airplane propellers.

Sizing Model Airplane Propellers

Obviously, the most important aspect is the propeller size.

Although determining the perfect diameter and pitch is crucial, it's much easier than you may think.

Get the low down on sizing your propeller to fit your airplane and flying style.

Types of RC Airplane Propellers

The construction or type is also a personal preference.

Do you go with a wooden prop?

Would a carbon or fiberglass reinforced propeller suit you better?

Find out which is best for you by learning bit about different propeller types.

Why Use Muliblade Propellers?

Should you get a prop with 3 or 4 blades? If you're looking for pure performance, probably not.

But 3-blade propellers can be a good choice for beginners simply because they slow the airplane down.

There are also a few other applications where multiblade propellers are needed.

Balancing Propellers

RC airplane propellers spin around pretty darn fast, so it's important to balance your propellers to eliminate vibration which could damage the bearings in your engine, motor, or airframe.

The larger the aircraft, the more important balancing is.

Here's a quick tutorial on balancing model airplane propellers and some neat balancing tools to check out.
