21: Free Flight Transition
Whether transitioning from free flight to motors or vice versa, there are important differences. It’s a lot more than just adding/subtracting thrust: those who pooh pooh the transition do a serious disservice to its challenge. And you will find those who like to fancy themselves as superior—be immediately leery of them.
Each endeavor has its own needs and idiosyncrasies. Respect them and you’ll do well, slough them off and accept potentially life-changing consequences.
