this is my first time buying an hpi product. i bought the sprint2 flux last month and i've only ran it for a total of 15 to 20 mintues. every few mintues the pinion gear would slide and the car would stop, so i would tighten it, and it would happen again... but the last time the plastic stem that is apart of the motor broke off. now i need a new motor... do you think hpi will replace the motor?
