Whether or not you have realised this Nancy Bird, when you started in the Jabiru you were training for your Pilot Certificate under Recreational Aviation Australia
unless of course, its a VH rego Jabiru.
in the end, aircraft type shouldn't make a difference, what will make a difference is how you feel with your instructor, a good relationship will be far more beneficial than one you dont like. a good instructor will teach you just as well regardless of aircraft type.
my instructors tip. DO YOUR HOMEWORK! remember, Prior preparation prevents pss poor performance, this even goes for training, after your lesson debriefing, ask for the material on the next lesson. take it home and read up on it.. while going over the texts about your next lesson, dont be afraid to ask your instructor questions about the next flight while doing your homework.(via sms is the better way) good instructors will let you do this, and even encourage it. it will put you in a league above the students that dont. making you a better pilot, and save money as well.
