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 […]

Techtip video: turn fins and trim tabs
Generally, the turn fins should be mounted as close to the sides of the boat as possible at 90 degree to the bottom. As the boat leans into a turn, the turn fin enters the water and acts sort of like a brake in the sideways direction. Note that they should “touch” the water only […]
Techtip: choosing a proper soldering iron
If you are serious in RC then you will for sure need to use soldering iron to rewire stuff. When choosing a soldering iron we recommend that you pick one that is at least 60W. 20W and 40W are too weak – you cannot make good solder join under such weak power. 60W should be […]
Techtip: RC Boat propeller rotation direction
Most RC boat propeller spins anti-clockwise looking from the back. You cannot flip the propeller so you must connect your motor and configure your transmitter properly.
Techtip video – RC boat shaft cup issue
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.
Techtip video: deans plug is loose
When battery power is strong, deans plug is a better choice than the tamiya plug. However, upon prolonged use the plastic shell of the female plug may deform giving excessive room for play and loose. You may use a flat head screw driver to ply open the flat metal plates on the male plug so […]
Accommodating larger battery in your RC boat
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 […]
What is a roller?
A roller is a basic RC vehicle with no motor or electronics. A pre-roller is one without tires and maybe no shell body too.
Techtip video: Built-in motor cooling fan for RC cars and boats
Newer generations of RC brushed motors often come with built-in cooling fan. While this feature can improve cooling, the fan itself when overheated can crack and break very easily leading to complete motor failure. Therefore you cannot rely solely on it for motor cooling. If you are to install a heat sink, make sure the […]
