it is somewhat hard to prove if the shorter boom improves tail response. it's more complicated to calculate than considering the inertia and torque of the tail alone. what matters is if the overall effect of reducing inertia is more or less than linear:
True, I shouldn't have implied that it goes without saying that it would be faster. In plain English, we have several forces which can conflict with each other. On the one hand, there's the fact that if the tail boom is longer, the tail motor has to travel farther in order to rotate the heli a certain number of degrees. On the other hand, there's the fact that the longer the tail boom, the more leverage the tail motor has to overcome the inertia and start or stop the heli rotating. We'd need to work out the correct coefficients for these variables to solve the equation.
