I don't know if this will work but I'm just trying to upload a new document we have just completed which has the service and maintenance schedule for the Rotax 80 hp and 100 hp engines. This is the first time this information has been accumulated in the one resource (according to my own investigation and that of the RAA Tech Manager). The RAA Tech Manager is going to give our form the RAA official approval and blessing and this website is the first place on the Internet you will be able to get this information.
