FEZ Mini Robot kit received with two different size motors,

I hadn’t noticed this until looking at the robot on a level surface. My 2 motors are of different size! The chassis mounts on top the motors and the chassis is seriously tilted towards the side of the smaller motor.

The robot kit went together without problems and the robot is operating fine, with some hardware additions.

My question is: Is this normal? Has it happened to anyone else?

Will this cause a problem (example: wear) in the future.

Thanks

Maybe it was mounted backwards, not sure. Please attache a picture.

It seems my chassis wasn’t screwed down all the way…(Funny, it seemed like it was when I built the robot) That and a strong visual illusion made the motors look different size. That is a good. simple zero-cost fix.
