I would like to direct you to a post I made a while back. It summarizes my feelings on how flying should be designed. Most responders didn’t like it. There are aspects in all fantasy that are grounded in realism, that is undeniable. That’s what makes the magic we do see so unusual. Momentum of movement is one of those things that give an authentic feel in a setting. Seeing a gyrocopter or dragon simply stop on a dime from full speed, whip a 180 and accelerate to full speed instantly in the opposite direction is immersion breaking as it violates the ideas we’ve already established with the momentum we experience when on the ground.
