Aussie Boomerang Updates

[Michel Lemieux]

I remember a magazine article many moons ago where the builder ( one of the Sander's ? ) quoted that, had they know how difficult this build would have been ( using the T-6 center section & scratch-building around it ) they for sure would have choosen another route to get the finished product.

From memory only.

Still, a very nice effort back then to re-create something that did not exist in flying condition. I am quite sure it should be a safe flyer.......If you respect the design limits. Like any other AC

It might be quite an 'ineresting challenge' to get the thing licensed outside the US, though.

yes, this Sander's replica uses a stressed metal rear fuselage rather than a steel tube rear fuselage with plywood covering, but that in itself isnt the main issue, its that the Boomerang centre-section and wing outer panels are significantly different and stronger than the modified T6 wing, and even substantially stronger and different from the Wirraway wing for greater engine and wing loading. I am not sure that would be a problem from a safety point of view if operated within its adjusted design limits, but above someone indicated the clipped T6 wing created some aileron concerns? in handling as well?

Subject to appropriate engineering, handling and operating conditions, I still think it would be a great low entry purchase into a replica of a unique combat design, and certainly of more interest than a Nangchung etc.

I think this example already has a jump seat for passengers?

The Sanders/Clarke replica has the ailerons moved inboard as I recall, not just clipped tips. The Clarke/Wocjiak NA-50 had just the clipped tips. It exhibited the same type of aileron buffeting that the standard high roll rate T-6 bellcranks cause, maybe a little worse, but certainly no control reversal problems.

Its "Step-brother", Guido's Boomerang A46-206 flew for a period in Australia with exactly the same wing structure, and Australia now has both an Experimental and Unlimited Category so I personally think as long as a local structural and design engineer is happy with it an Australian buyer could buy and fly it here.

If it has been authorized, then it's ok.
