Modern RC cars have very high current draw, that even Dean plugs may not be able to survive the heat generated. The trend is to bypass these connector plugs so that the connections go directly to the battery.

The receiver needs approximately 6V of power to operate. In a typical configuration, the ESC supplies this power to the receiver. Some ESCs can adjust the voltage in a safe manner to avoid blowing up the receiver. Most cheaper ESCs cannot. If you supply too much to the ESC, the… Continue reading →

We use 7.2V batteries here as examples for discussion. The 3700mah GP pack is so strong that when it is fully charged its effective voltage output is very close to 8.88v. The Intellect 5000mah pack is even stronger. Size-wise, a very close alternative to 7.2V nimh is 7.4V Lipo. Lipo… Continue reading →

To connect receiver and ESC/servo produced by different manufacturers, you may need to do some work on the connector. Say, if the connector plug has a shape that cannot fit into the receiver port BUT the wires seem to match (based on their colors, for example – White, Red, Black),… Continue reading →
