The Unimog U500
Here is my entry into the competition, it uses four motors (two for driving, one for the turret, and one for the steering.) It also has a gear ratio of 1:24 which was a little overload but I thought it was needed for the use of M motors.
All Terrain Tank
Here is Michael's Tank, it uses 2 M motors (one for the right treads and the other for the left treads.) It has a gear ratio of 3:5 which as for as I could see worked well with the small chassis and lightweight construction.
As you can see we had very different entries but overall I think they both worked out nicely. Thanks for reading and if you have any Questions or Comments just ask them in the comments.
