This dyno is a high-quality analyzing tool intended for persons
aged 18 years and older with previous experience building and
operating Radio Control vehicles. This is not a toy; it is a preci-
sion testing equipment. This dyno is not intended for use by
beginners, inexperienced customers, or by children without di-
rect 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 pur-
chased 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 universal chassis dynamometer (dyno) that is ready to test gas or electric vehicles out of the box. Featuring an onboard
electrical board equipped with an optical rpm sensor that measures motor speeds at up to 50,000 rpm. The board is also equipped
with external ports for an external LCD screen, throttle controller, and dierent types of sensors for measuring voltage, current,
and temperature.
Its adjustable wheelbase and upper deck give the option to test dierent sizes of vehicles (TC, Truck, Buggies, Motorcicles, etc). 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, ESC (boost) adjustment, brushless sensor adjustment, gearing calculation, acceleration
testing, kV measuring, voltage drop, current draw, power, and torque output analysis.
* May not be included in your kit. Please verify the included accessories in your purchased kit.
