When your boat has damages everywhere it may make a better sense to give it a new body. PVC pipes are cheap and easy to work with. You can keep the undamaged part of the boat and use it with the PVC pipe frame. Yo can even create a rescue boat this way. You may […]

RC Boat Techtip: preventing rudder damage
Most RC boats steer by means of the rudder, a vertical, blade-like appendage mounted on the transom and controlled by the servo. When sailing in shallow water it is quite easy for the rudder to hit the bottom and get damaged. One useful trick to prevent damage is to use zip tie instead of screw […]
Fixing lipo charger cooling fan
A lot of the time the charger gets overheated due to a defective or weak cooling fan. The photos below show the replacement of a 12V 2mm fan inside a BOL charger. They are pretty much self explanatory: You may need to solder the wire so to make use of the correct wire plug. And […]
DIY RC boat rescue kit
Building a rescue boat is never easy. You may start with building a custom mount addon for an existing boat and then add PVC pipes to it. However, without carefully adjusting the weight balance the boat will never be able to sail properly. It may even dive. PVC pipes are heavy relatively to a RC […]
RC techtip: RC boat (monohull in particular) nosediving…
This example shows a monohull. In an attempt to find a way to prevent the boat from being pulled to one side due to torque roll, an extremely large trim tab is installed. The result? Yes the torque roll problem seems to be resolved. However, the boat nosedives easily at full speed! Therefore it […]
Water cooling design for boats running 4s to 6s
On a high power running 4S or even 6S, you want to have a separate water stream for the ESC and the motor so they both can receive fresh cooling. On the 6S system the wires can get real hot. It is therefore worth trying to having some cooling capacity shared with the wires: […]
Larger scale RC boat rudder and water cooling
On larger scale high performance RC boat the rudder often serves as the water inlet. The rudder is heavier and the inlet is small, but due to the high speed there is still going to be sufficient water moving into it. Some smaller high end boats also use rudder that also serves as water inlet […]
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 […]
