Ducky you are another sucker. Exactly why do you think CASA will allow you to play around with RAA or SAAA aircraft after it has finished off GA???
The answer of course is that they will come after you in due time.
To put that another way! as per the Jabiru precedent now set, your aircraft can simply be declared "unsafe" and there is nothing you can do about it.
Another trick of course would be to massively inflate your costs.
We stand together or we get picked off one by one.
