MiniPRO presented a dyno to measure RPM (Revolutions per minute), kv, voltage, current draw, power and torque output of a slot car. This tool is perfect for motor analysis and gearing calculations. The MiniPro Slot Dyno uses the engine to accelerate a flywheel and the electronic board calculates the power and torque of the motor by gauging the flywheels inertia and its acceleration.

The MiniPro Slotcar Dyno repeatedly measures and calculates power in small increments to produce an accurate graph on a PC of the engine’s power characteristics.

MiniPro Slot Dyno Measurements:

• Tire RPM.
• Power Out.
• Power In.
• Temperature readings.
• Voltage.
• Motor RPM.
• Speed.
• mAh.
• Efficiency.
• kV/rpm.
• Torque.
• Current.

The dyno uses a custom PCB with an Optical RPM sensor, delivering low noise and accurate readings. It features a built-in micro USB for connection to your PC. It includes one external LCD port, one external throttle controller port, one current and voltage sensor port, and two temperature sensor ports.
