Frequently Asked Questions

What is the maximum recommended battery voltage for this Rocket 3670 motor?

The motor is rated for a maximum voltage of 23V, which corresponds to a 6S LiPo battery (25.2V fully charged). For continuous high-load operation, it is recommended to use a 5S (18.5V nominal) or 6S system with a compatible high-current ESC.

What type of Electronic Speed Controller (ESC) is required?

You will need a brushless ESC capable of handling at least 70A continuous current and the motor's voltage range (up to 6S). Ensure the ESC firmware (e.g., BLHeli_S, BLHeli_32) supports the motor's low KV and pole count for smooth operation. A marine or car ESC with adequate water cooling may be necessary for RC boat use.

Is the 5.0mm shaft pre-drilled for prop adapters or collets?

The shaft is a standard 5.0mm diameter smooth shaft, typical for high-power applications. It is not pre-drilled. You will need to use a matching 5mm bore prop adapter, collet, or pulley system secured with a setscrew for your specific application, such as a propeller for drones or an impeller for boats.
