What German construction kits cost 8-10000usd?
For about 20% additional cost you can get a basic Fumotec or Premacon kit that'll not only outlast that china crap 1000 fold, but also has the power & ability to rip that low grade soft aluminum china structured kits to shreds. Fumotec & Premacon are built mostly from steel & high grade aluminum.
The difference in quality of construction materials & electronics of German made vs Chinese made is as different as their economies... China uses their recycled metals full of impurities combined with their 10cents/hr laborers, the Chinese are the ones who make huge profits despite their ~slightly~ lower price!
Your loader and excavator, with it's axle problems, hyd leaks, electronics that catch fire... how long will Eagle machinery keep supplying you with free parts... 30days? 6months? ...yrs? Do you think you will get 10yrs regular use out of a china model & still be less overall cost than German made? I'll put money on it you won't! And then there's resale $$$$ value, which one do you suppose will take the bigger loss?
