This dyno is a high-quality motor analyzing tool intended for
persons aged 18 years and older with previous experience
building and operating RC cars, boats, airplanes, and drones.
This is not a toy; it is a precision testing equipment. This dyno
is not intended for use by beginners, inexperienced custom-
ers, or by children without direct supervision of a responsible,
knowledgeable adult. If you do not fulll these requirements,
please return the kit in unused and unassembled form back to
the shop where you have purchased it.
Before building and operating your dyno, YOU MUST read
through all of the operating instructions and instruction man-
ual and fully understand them to get the maximum enjoyment
and prevent unnecessary damage. Read carefully and fully un-
derstand the instructions before beginning assembly. Contents
of the box may dier from pictures. In line with our policy of
continuous product development, the exact specications of
the dyno may vary without prior notice.

This is a slot car inertia dynamometer (dyno) that is ready to test electric slot cars out of the box. Featuring an onboard electrical
board equipped with an optical rpm sensor that measures motor speeds at up to 100,000 rpm. The board is also equipped with
auxiliary ports for an external LCD screen, throttle controller, and dierent types of sensors for measuring voltage, current, and
temperature.
A balanced ywheel (inertia mass) is enclosed by a high grade aluminum 6061 cover to provide safety. The ywheel is replaceable,
that means you are not limited to the same load when testing your motors.
This dyno is great tool for motor analysis, gearing calculation, acceleration testing, kV/rpm measuring, voltage drop, current draw,
power, and torque output analysis.
* May not be included in your kit. Please verify the included content in your purchased kit.
