List of motors that fit the new ERCU motor rule

3/1/2021

 
A number of requests have been made for more information about the motors that are now legal in ERCU under the new motor rule. While the rule does NOT specify any motors - rather the legal dimensions of motors - the list we are providing is a list of suggested motors that fit the new rule.

The motors on the list were all tested by Darin Jordan and published in the April 2018 NAMBA Propwash. They all fit within the dimensions of the new motor rule and are now legal in ERCU.

It is entirely up to each racer to select their own motors, and adjust your set up during your testing in the offseason. This list of motors is purely for your information. Please remember the dimensions of the motor are the guideline for the rule - not the motor make, model or kv rating.

Here is the new motor rule as it has been approved:
  • Power is to be provided by a single motor meeting the following requirements:
  • ERCU motors shall be of an in-runner design and shall not exceed the following dimensions:
  • Length: 60mm (2.362 inches). This includes any bearing protrusion.
  • Diameter: 37mm (1.457 inches).

These dimensions and specifications include the Himax, Dynamite and Aquacraft 1500kv motors, making them all still legal for use in the club.
