This type of rudder configuration is common. The possible rudder range of rotation is about 30 degrees. However, because it situates closer to the right, you will find that making left turn is relatively more difficult. To solve the problem you will need to make substantial modification to the rudder. As you can see from […]

On shallow water with bottom full of rocks and stones, both the rudder and the propeller can easily break. What is worse is that if the rudder is stuck and you keep trying to turn, the small servo can fail. If your rudder has the potential to hit the bottom, consider to cut it shorter […]

Smaller scale RC boats that use 370 motor are usually without water cooling. Instead there is a cooling fan attached to the main shaft. These boats are pretty fast, but due to a small compartment heat can become a problem. There are several things you may do to alleviate the heat problem. Firstly you can […]

Smaller scale RC boats are usually direct drive, and the shaft hub is usually a plastic piece wrapping around a metal shroud without using any hex screw. The structure can get loose pretty easily when you upgrade to a more powerful motor. You should therefore apply superglue to secure it.

Smaller RC boats such as the Feilun FT 009 and other OEM variants have limited space in the compartment, making it difficult to accommodate slightly larger battery. The water proof cover in particular has many useless plastic that can be removed to allow fitting of larger 2S or even 3S pack. Battery pack that is […]

This video shows a RC boat upgraded with a larger prop. There is a problem with the installation, that excessive vibration makes the boat very unstable at high speed. If you look carefully, the entire outer draft assembly is spinning together with the shaft, which seems to be the cause of vibration. This can lead […]

This video shows a FT 009 RC boat equipped with a larger prop. The black prop shown in the video is the stock one and the red prop is slightly larger than stock. With the larger prop installed, the boat obviously runs faster but the run time is reduced. Also, the battery and the ESC […]

This video shows a Widebody Catamaran style RC boat. It is very stable and easy to make turns without losing control. The problem is that the hull is rather flat so there is very little room inside. Heat accumulates real quick even with the presence of water cooling. If your electronics are water proof I […]

A lot of the time the receiver-esc integrated unit that comes with an entry level boat just won’t be good enough when you are installing a new motor. In this example a strong magnet 380 motor replacement is way too demanding for the entire system. We got a burnt wire and an overheated circuit as […]
