Electronic RPM counter provides another fast and easy way to measure the speed of all brushless motors on our site.
This kit includes all components necessary to build the counter. Assembly instructions with typical setup for motor speed measurement are provided. Uses standard 9 Volts battery (not included).
It is a wonderful project by itself but assembly requires certain skills and experience with soldering and might be difficult for a beginner.
Please note that original digital counter kit was developed by another company and therefore we do not provide any additional technical support besides its use for RPM measurement.
