Interesting topic, but I am glad my 1/14scale wheeloader doesent weigh in at a whopping 3,730 pounds

(metric= almost 1,7 Tonnes) , if it were so I believe some kind of reinforcement of my tv table would be needed
I like to think of it a little different:
What can it lift in comparison to what it actually weight's?
Example is my wheelloader: It weights almost 8 kilograms, but it can lift almost 4Kg to the top. I dont think that is bad at all?
