Chapter 27 Choosing Gear: The Motor   Matching Prop to PPG   Paramotor Torque   All About Fuel   Avgas vs Mogas

There's a lot more than meets the eye regarding the choice of motor. Thrust, sound, strength, cage size, shipping ability and others. Don't expect to get a straight answer from manufacturers. Only a few really state the facts and a few blurt out utter nonsense with a religious conviction.

Another thing that has become obvious is how pilots tend to like what they learned on. As we cover elsewhere, before choosing your first motor, choose an instructor and make sure they're familiar with the gear you plan to learn on.

I've been asked about torque and twist many times and find a tremendous amount of misinformation. Sometimes it's given with religious fervor. It's still wrong. I've worked with other respected pilots and aerodynamic experts to gather consensus for the PPG Bible and we are on agreement with what's presented there. Here are some highlights.

Here is a great video showing how a 2-stroke engine works and how a membrane carburetor works. It's intent is to show servicing of Walbro carbs but it's very informative.
