Dang it, I had been able to fight off the "need/want" for a gyro. But there are some good arguments here.
I remember back when tail gyros first came out for helies, you heard the same crutch argument and the learn to fly arguments. Now it is nearly unheard of to see a heli without a tail gyro. And few heli pilots would know how to fly without one. Now most helies "need" a full 3 axis gyro to fly. I can certainly see airplanes going the same route.
So far I have never flown a gyro in an airplane, but my next build I have been told by many that it does need a gyro on at least the nose gear. I am planning to get the Cortex since it can do nose wheel, twin independent rudders and elevons.
