I just received my 973 V2 loader. I got it in kit form but it still came assembled. I took the majority of it apart to paint it since I think that was faster than trying to mask off all the windows and everything. Plus I had to tear apart the cab to install the lights anyway. I think its a great design and it has re-assembled very nicely. I also run a converted bruder excavator with magom hydraulics and it has been great. I did run into issues with the esc's. They are not programmable, and they came way out of wack from the factory, as in 1 track was running full speed when I initially plugged it in. So I am going with a sabertooth motor controller and here is the reason.. The service from them is quick! but they wanted me to send them the old escs back so they can "fix" them, and I just do not want to wait for shipping to and from Spain. The other small gripe I have is trying to package all these electronics into the small space. Its definitely doable, but its been a fairly painfull process of trial and error so far, and for some reason do not want to send me any pictures of their factory assembled models to make it easier on me "I have asked" What makes it bad is that the whole thing went together so fast and easy I was all ready to get digging within a day of receiving it! but the electronics held me back and I got bummed
If I had to do it again I would either get it RTR or no electronics. BUT, overall I would have to say I am very happy with it, 9/10 rating, heavy machine, good mechanics, good hydraulics, nice and quiet and seems very powerful.
