If you can easily push the car while there is no power to the motor, then you will also have a weak drag brake. Motor and gearing, like 89Industries said, both play a big part in this.Thanks, Oh, it is just a basic 540 silver can,, probably amongst the weakest variety. So that might (hopefully) explain it !!! I had noticed the motor didn't have the strong magnetic phases when I turned it over by hand. Is it that magnetic effect that I need to have in a motor to get the drag brake to work ?? I will find a stronger motor & give it a try. Many thanks for your reply to me, I appreciate it. thanks
