Digital Commander Issues

[racecarchris]

My son recieved the Digital Commander for Christmas and we have issues with it right out of the box. The red engine is grinding when we try to use it. It sounds like the gears aren't right. Is there an easy fix solution for this I can do myself or is it something I would have to send in to fix?

      By the red engine I assume it is the FTA Sante Fe . Check the trucks, make sure the side frames are snapped in place and not binding on wheels/gear. While your checking eyeball the drive gears in both trucks.You can lube the gears with some Silicone oil or an oil that is plastic compatible.If you find damaged gears submit the engine for repair or replacement.
