You'll also learn about competition and free flight. It's especially useful for those transitioning from free flight to motors.
Section IV: Theory & Understanding
You'll fly even without understanding aerodynamics but it helps. Same goes for the more thorough treatment of weather and motor dynamics. The history chapter is just plain interesting.
Section V: Choosing Gear
After learning to fly, pilots frequently sometimes want to buy different gear. These chapters help make informed decisions, including what to buy for home building.
Section VI: Getting the Most Out of PPG
