Touring Motor Glider Association Dedicated to discussing and promoting touring motor gliders, including Phoenix, Taifun, Fournier, Xiango, and many others.
The TMGA is a non-profit, volunteer organization dedicated to promoting and advocating for the safe, efficient, and enjoyable use of touring motor gliders. Our primary objective is to collect and disseminate resources that are beneficial to owners, pilots, and enthusiasts of this class of aircraft. They aspire to become the global reference source for all information pertaining to touring motor gliders. They firmly believe that touring motor gliders offer the optimal way to maximize the utility and enjoyment of pure flying.
Examples of touring motor gliders include, but are not limited to: Aeromot Ximango, AMS Flight Carat, Diamond Xtreme, Fournier RF-X, Grob 109, Distar Lambada & Sundancer, Phoenix S-LSA Motorglider, Pipistrel Sinus & Virus, Stemme S10 & S6, and Valentin Taifun.

Technical Info Website and Newsgroup Resources for Wankel-engined Motorgliders
Long-time ASH-26E owner/pilot Eric Greenwell maintains a great "Tech Site" and an active Google Group for Schleicher Wankel-engined motorglider owners and professional maintainers. The "Tech Site" contains technical articles on many different subjects containing comprehensive and detailed information useful to those who maintain and fly Wankel-engined motorgliders. The Google Group provided a discussion and information exchange forum which keeps the Wankel-engined motorglider community informed and up to date on the latest news and issues, and is a searchable resource for historical and technical information. Eric maintains these resources independently from ASA, but he wants ASA members who own or maintain Schleicher Wankel-engined motorgliders to be aware of these valuable resources. If you own or maintain one of these and would like to request access, send Eric a request via email. Include your name, country of residence, type/registration/serial number of motorglider owned/maintained, and email address. Eric's email address is

Important Notes:
The bi-annual SSA convention was held in Knoxville, TN in October 2024. The ASA President, Tom Seim, gives his observations on trends in the sport of gliding, the exhibits and on the presentations he attended.
The convention highlighted the growing trend of electric motorgliders, with manufacturers addressing heat dissipation challenges. The ASA Motorglider Maintenance Seminar received significant attention, covering various maintenance topics and updates on new technologies. The convention also featured presentations on hydrogen-powered gliders, in-flight tow hookups, and the Perlan high-altitude pressurized glider.
