I've just purchased an HPI sprint 2 sport RTR and noticed that it is not braking at all! However, when I lift the car up in the air and apply brake, it does seem to work... (motor does its braking sound and the wheels stop) the problem is when the car is running, no braking power at all, it just freewheels. Reverse is working.
Could it be the ESC? its a HPI SC-15
or maybe the belts?
Anyone else had similar trouble?
I've sent an email to HPI but since their support time is several days away I just thought I'd ask here
