ive recently pulled out my two ecx cars (I have a 2wd ruckus and a 4wd torment) and decided to try to finish rebuilding the torment since I had all the pieces or so I thought. I bought a titan 12t to put on it for a little more power but it seems the motor is a little to big. I set it in place to mount and the pinion is sitting about 1 to 1.5 millimeters away from the spur gear. did I do something wrong somewhere? I only got the titan motor because there was another person in the store when I bought it that had pictures of his with the titan motor. ive never taken the cover off the spur gear either if that makes much of a difference. if anyone has any helpful tips or hints about this it would be greatly appreciated.
