Yokomo X Series - User Manual

1.Introduction
Thank you for trusting YOKOMO products. Purchasing RPXII Competition Brushless ESC
means that you selected the best ESC out of currently existing ones. This ESC is integrated
with Hi-Tech features, and it is the most outstanding ESC you can get in the market. It
is very dangerous when used improperly or remodeled without an approval, and this
can cause critical damages to peripheral products & devices. Please carefully read this
manual before use of this product.
2.Caution
■ To avoid short circuit, please check if the wires and connections of the ESC are
protected and are not in contact with peripheral devices.
■ Be well-acquainted with the user manual for power devices / chassis before use, and check with the operating ranges.
■ Use a soldering iron with at least 60W for soldering all input / output wires and connections.
■ Keep the operation atmosphere dry in order to protect the ESC from humidity, water, oil, and other substances.
■ Allow the product to have good ventilation, and be cautious for overheat.
■ The ESC must be separated from the battery after use.
3.Features
■ Full aluminum case and heat sink design
■ Full compatibility with modifi ed and stock race
■ The excellence of the software reduced the motor temperature by modifying commutation algorithm and upgrading
hardware, and it also increased the speed.
■ New turbo / 3 Models of boost timing setting and delay time setting.
■ It became possible to have various types of race and controls by setting new brake response mode and PWM / brake
frequency individually.
■ It is settable by connecting ESC to a program box or WiFi module with separated program port
■ Using new WiFi module, the user can set the program parameter and upgrade the fi rmware. Also, all the ESC & motor
data such as temperature, current, voltage, RPM and battery consumption can be stored in real time with the data
log.
■ Using superlative FET and low resistance power PCB design
■ Maximizing the cooling with a 30mm fan
