Kevin,

I have the Fighter UL plans too. I just checked your website and I'm glad
you have made that resource available. I emailed Durana with some questions
but he has not responded.

The plans don't show nearly enough detail and the 2024 specified for the
spars is ridiculously expensive. Every ultralight I know uses 6061. For
added strength in critical areas, such as at the strut attach points, double
or even triple-sleeving can be used.

I'm pretty much decided on building a Minimax now because of the problems
with the Fighter plans, but will be checking your website to see how the
builder community is doing. Some interesting solutions being proposed there.

Regards,

6061,6063,2004,6060 ..ARGHHHH!

Question if I may.......
On the plans of the Homebuilt I am building it calls for a Boom.. The
material requested is 6063-T3 (Which I cannot find anywhere)
After much discussion the designer noted that if you cannot get 6063-T3
you can use 6061-T6.. Great .. Until I found out I cannot get the length
required in Australia...
After discussing with an Aluminium supplier here they have suggested that
I can use 6060-T5 as a replacement for the 6063-T3 as the length I require
is available in this grade.

Although he would know more than me about aluminium I still feel
uncomfortable with his advice and my lack of knowledge......
Can anyone advise?.. If 6060-T5 is NOT suitable can you suggest a million
other alternatives I can choose from.....
