Even though remote controlled boats are a small version of a boat, understanding propeller pitch is exactly the same. Size doesn’t matter – the propeller still does the same thing on both sizes of boats. Here’s my understanding of pitch for a RC boat propeller.
Remote Controlled Boats – The pitch is the forward movement per revolution of the propeller!
I hope that makes sense to you. This was the hardest thing for me to understand when I started with remote controlled boats. Since I didn’t have any experience with boats in general but loved the thought of controlling a boat on the water, remote controlled boats were the obvious choice. So, let’s continue with propeller pitch.
A better explanation of propeller pitch comes from wiseGEEK:
“Propeller pitch determines the speed and power that a propeller will produce. The
amount of propeller pitch refers to the angle of the propeller blades as compared to the
propeller hub or a horizontal line drawn through the center of the propeller. By altering
the propeller pitch or the angle of the blades, the propeller can be tuned to deliver
more top speed or more slow speed power or torque.”
This explanation allowed my brain to understand what pitch does on a propeller. I hope it helps you too.
Why you need pitch on remote controlled boats
There’s a lot more to propellers than just the pitch however. The pitch is the most important, but there’s also the diameter and cupping. We’ll cover those in another post; in the mean time, if the pitch of your propeller is off you can easily break the shafts, gearboxes, and the control rods in the engines. Not to mention shaking the heck out of your RC boat and breaking the motor mounts. So instead of replacing the prop you’ll end up replacing the whole boat. That’s also why you don’t run with a damaged prop.
The pitch and diameter are the most important part to get right for a prop; otherwise the engine struggles to get you where you want to go. If you’re into racing competitions then having the right pitch will get your remote controlled boats across the finish line first.
When pitching remote controlled boats
When setting the pitch on a prop you’ll need to know a little more information such as the RPM of the engine, diameter, and the number of blades. You’ll also need to know the pitch calculation which is a math formula but if you aren’t any good at formulas then there are many pitch calculators on different website you can use. You can also look for a pitch gauge to do most of the work for you. At this time they are rather hard to find so if you do find one let us know where you found it so we can share with our readers. They will greatly appreciate it.
There’s much more to remote controlled boats than propeller pitch
Pitch is only the beginning when setting up your propeller to get the most out of it. There are blade cupping, prop diameter, rake, and vent holes to explore as well. Next time we’ll cover blade cupping and propeller diameter. Come back in a couple of days to find out what they are or click on our RSS feed to keep in touch.
