Electronic RPM counter provides another fast and easy way to measure the speed of all brushless motors on our site.
Assembly of the RPM counter from the kit requires certain skills and experience with soldering. This task might be too challenging for a beginner.
Assembled counter comes with instructions on how to use it for motor speed measurement. Battery is included.
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.
