Why is this blog called Hanger Rash? It’s meant to be a place for discussing advanced concepts and aircraft conceptual design studies for models found in the VSP Hanger.  If you look up the definition of Rash you will see that the meanings are… “Resulting from ill-considered haste” or “Quick in producing a strong effect”.  Advanced concepts often generate these opinions, as new configurations with new technologies are seen for the first time.  I’ll attempt to explain if new concepts are nonsense or merely generating a strong response.  Remember, anything really new seen for the first time always looks strange; the question is, does new = better.
