Alex L. Varv Back to Aero Cors-Air Home Page While our competitors publish only what brings them financial gain, over the years, we tried hard to give as much info and technical support possible to everyone in the community for FREE. This is how was born. With a worldwide contribution of very informative articles, our web site became one of the most complete PPG web sites in the World. The Inventions Page is a totally non-commercial section that brings to anyone's fingertips the most complete inventions and innovations done by pilots from around the globe! Aerocorsair USA has reserved this page as a nonprofit forum where any pilot can publish, free of charge, any improvements and innovations done on any paramotor or engine, be it even our competitor. We hope this page will serve for the benefit of our PPG flying community.
