No APC props on trainers or tail draggers with inexperienced pilots, one prop strike and you can toss them in the trash, same with wood props. You get a better idle with a composite prop anyway, it's heavier and acts like a flywheel, engine doesn't loose as many RPM between combustion strokes thus a smoother idle.

The most durable training prop is the black Master Airscrew, and don't bother using the pretty spinner that comes with the plane, use a "spinner-nut" (looks like a round nose aluminum bullet with a hex on the back) because it makes maintenance at the field much faster and easier.

Remember, a trainer is a tool to teach you to fly so keep it simple and the more complicated you make your training the more aggravated you make your instructor....[:@]
