The information and training provided in a Novice course is crucial to your long term success with a motor. It is our opinion that you want the most lightweight, durable, and powerful motor you can purchase.

Although you will hear otherwise from some motor distributors, you do not usually need a larger glider than the one you would fly without a motor. We actually want you a little heavy on your glider.

Develop a solid relationship with an instructor experienced in motorized paragliding before purchasing equipment.
