EEr,i was saying no such thing.I can see how my use of the word 'either' in that sentence mislead you.(sorry for that but simply not what i meant to imply).I was not saying that those machines do not use any aluminium at all, and the only one of those machines i said i can't think of any use of Aluminium in, is an F1 car, and i can't.(Not in aircraft alloy form anyway,which was the comparison being made-not meaning the element is not present in other alloys-Ti alloys have Al in them for example),they use magnesium alloys for the block,uprights,wheels etc.I certainly was not claiming that not one piece of aluminium was used on concorde.

I was not trying to pass off the use of aluminium at all, i was merely objecting to the use of titanium in RC being branded unneccessary and mainly for bling,just because someone can't be bothered.Of course we all use and rely on aluminium,it's practical and easy to work with,light and stiff.If anything i was trying to seperate the comparison between the two,as there properties are not at all similar,used in different applications to aluminium as a lighter alternative to steel.(read my entire post)

The 'all the best machines' comment was meant to imply that when people want to build a special machine,such as Dafni seems to be thinking of one of the best trucks out there,then inevitably we will look to select the most ideal material in each area.My point was and still is, that aluminium is not always the most ideal and Ti is far from unnesessary.

Peace.
