Hello, now I have some of the original Lego cars on the tooth felt.

Have fun looking, greeting üfchen.

 

 

 

I think the idea of a conveyor belt for surface interaction testing "a la wind tunnel for aero testing" is a brilliant idea, however because the forces aren't acting in the same way/ on the same surfaces as they would be if the vehicles were driven, it can't be used as an accurate way of testing. If the vehicles were powered through driven wheels and we're not held in place by a point in a position other than the axles, this would be brilliant. If, however, this is exactly as you wished this clever contraption to operate, the only advice I can give is perhaps to lock the vehicles with HOG steering straight as they have no caster angle to keep the steering centred on its own.

I personally love this idea though as it might help to adjust suspension designs if made bigger for RC technic mocs, perhaps.

Nice idea  .

Hah, this is awesome!

Great idea to test suspension stabilization. This remembered me a part of suspension test for M60 tank (0:50): 

 

Hahaha, fun moc, and another original idea from you, well done.

I love how you modified the hook after the first car fell down :D

Great Idea and well executed!

 @ sacm93  The thought is great. I have to think about it. Thank you .
