If you have additional information (ex: specificity of piloting, various characteristics...) on the hang glider Esprit by Airwave, you can supplement his card by adding your comment or write to us :
The Esprit was not an Airwave glider. It was produced from 1983 to 1985 by Pacific Windcraft of Salinas, California. Intended as a higher-performance version of the Vision, it was particularly popular as a tow glider behind the La Mouette trikes that PW as importing.
There was only one Esprit ever made that doubled as a trike glider. I owned it. Due to its higher weight, its sink rate was poorer than the stock ones when flown unpowered, but the stiff frame gave it better penetration and glide at speed.
