Re: Bruder D11

Thanks Guys! I have been getting lots of usage out of this lately, I will try to make a video of it pushing dirt. I have to say I am always surprised at how well the plastic and the parts hold up.

Re: Earth Digger 4200xl from China

I purchased one of the hobby engine premium kits and was extremely disapointed. Do not waste your money on it. You will be much farther ahead if you buy a bruder and do the conversion.
