Alex Rizi Verified Owner Sunday, Jun 8 2025 (4 months ago) Reedy Sonic 540-M4 DE Modified Brushless Motor (6.5T) The DE line of Reedy motors are awesome. Real smooth and good RPM range. You need to fiddle with your ESC settings to get the most out of this motor but once you unleash good settings for your particular car you will be impressed. This was purchased for a friend and installed in a AE B74.2D CE paired with an Hobbywing XR10 Pro G3 and wow. After fine tuning the ESC the car was impressive to drive.
awesome low speed control and feeling and really good brakes. Thanks A-main. View all reviews
