rc4wd excavator ?

[A1 Dirt]

I have a 4200XL and am happy I bought it. I had an initial problem with the pump and pump motor, but RC4WD sent replacements. I only have a few hours on it since installing the parts, but have had no other problems.

Mine has been pretty good also,my stick cylinder is bypassing oil but other than that it has done ok. I now have changed the hydros over to Leimbach,valves also and put a dx18 to control it.I also changed the engine house and cab to make it more 1:14 scale . I have a guy here that can make cylinders out of stainless and the packing will be made like real cylinders are instead of o rings for the rod packing.I don't know if the hydros will push it yet though its still being made.The rc4wd cylinders have anodizing on the inside that is wearing and letting oil bypass. The inside only has one oring on the rod so it can't take a little wear.I know a bunch of yall have had no problems and some have had a lot of problems.I guess its a catch 22. The second version is definitely a better machine.I am happy with mine.

i set one up for someone and ran it quite a bit. i know 3 people that have them and are very happy with them. It is a nice solid machine. The pump draws a lot of current because the pump is about 4 times the power necessary to run that size machine but, it doesn't hurt anything as long as you turn the pressure down.

You should lower the pressure so that the boom has just enough power to easily lift one side of the machine up.
