The hiss of water against a hull, the sudden scream of a brushless motor hitting its power band, and the split-second thrill of a perfect high-speed turn—this is the soul of radio-controlled boating. But between those moments of glory lies the real craft: the grease under your fingernails, the late-night soldering sessions, and the quiet […]

RC Speedboat Parts Design with Fusion 360
This book is specifically tailored for RC (RC speedboat to be specific). It includes contents and activities that help you learn the key concepts and usage of Fusion 360 for the design and modelling of RC parts suitable for 3D printing. It teaches you how to navigate through the Fusion 360 environment, manipulate and edit […]
RC Techtip: What is torque roll?
When you use a powerful motor with a large and effective propeller, the boat may pull to one side (the technical term for this is “list” – the boat takes on water and tilts to one side) at high speed. That is due to very strong propeller torque, which refers to its twist-force. Assuming you […]
Replacing broken shaft cup on a FT009/016 RC boat
The stock plastic shaft cup on the FT009/016 is NOT a standard cup. It is plastic and can break if you upgrade to a larger prop or a faster motor. You cannot buy this shaft cup as a replacement part alone. Therefore, you either need to 3d print on your own ( https://upgradeparts.com/2021/08/13/replacement-shaft-cup-for-ft009/ ), or […]
Overheated motor on FT009 and the like…
The FT009 is one of the most popular entry level RC boats. It is cheap but quite reliable. However, when it comes to prop upgrade, it is often found that the motor can cook itself pretty fast. Upon closer look it won’t be a surprise to find that heat dissipation is less than 50% – […]
Can a boat still run with one prop blade gone?
This boat has a half broken prop with one blade gone. It runs although it does not go straight line properly. Also, it gets a little bit noisy. Still, it runs.
What if your boat fails to start?
If your boat is RTR with a safety switch facility integrated into the circuitry (the boat must be on water in order to start), it may produce no response after 20~30 rounds of use. This is especially true when the stock electronic is an ESC-receiver integrated unit. Seems like the safety connections oxidize pretty quickly. […]
Anti-Capsize Hull system
Just like most other modern RC boats, this FT010 has an Anti-Capsize Hull system which allows the boat to right itself when it flips upside down. Keep in mind, the feature is available primarily on boats with V hull, which is the most common hull for RC boats. Other hull designs may not be able […]
Very large propeller for larger RC boats
This FT010 has been equipped with a mega size propeller – 78mm! This FT010 RC boat is equipped with a 78mm propeller! This is more than double the size of the stock prop! To drive it you need to real powerful motor such as a 1500kv brushless, and at least 3S pack. The electronic speed […]
390 motor on a RC boat with gear reduction
This boat has a 390 motor and a direct drive like configuration, but in fact it has a very small gear reduction setup, delivering sufficient torque and excellent performance while not over heating the motor. With a proper balance in gearing and propeller size, it goes as fast as one with a 540 motor! This […]
