I think HMR and the 1/72 vf-1 models were basically released to fund research and design of the DX VF-1. The extra extension at the intakes is from the model and there are many elements of HMR in the transformation of the DX. HMR would cut into sales of more premium pricing on the DX.
It’s a damn shame, but I think when we saw the paint scheme change on the VF-4, we also saw the death of HMR.
it’s obviously just an opinion, but ever since the DX line started rolling, HMR started dying.
