We heard from one person that said our corrected H2OOOOOOO was slightly too large for 1/87 scale. So we rescaled one down. Left the larger version up. The 4x4 'BIG MEAT' tires will work with this. Because this is the most accurate H2 SUT out there, specialty flaws have been designed into the model making it impossible to copy cast. Plus the price was raised.. Copy casters ruin it for everyone. Copy coasters want to steal my designs, then it's going to cost everyone. Sorry, we must protect our designs from less than honorable people by any means possible.
