if you are interested in doing an endorsement then i would consider contacting Fox-Air
http://www.foxair.com.au/ near Geelong. They are the Australian distributor for Enstrom. He is a qualified instructor who maybe able to help you or put in touch with someone who can. The Enstrom looks like a strong alternative to the Schweizer 300 and i am interested in finding out more about them. The trouble is there is only a small number in this country compared to other types.
