Don't mistake ti being light weight. Those 3,5 mm ti skid's from GA wheigh allot, deffinatly not lighter if you copy the design in 3,5 mm 7075. So makeing an entire bulkhead out of ti isn't gonna be lightweight. Beside's, who need's such a thing, we got trouble destroying ga's or dace's. And they proof to be pretty darn reliable!(try to strip a good tapped thread in 7075)

Sneeck......

like i said, i would change the design..

the bulk could be made from WAY less material, lets see what weights more. ;)

here is the deal; titanium is relatively stronger and lighter than aluminum.

It's bulky allright, no doubt about that.

Would be quite neat to see one out of titanium for sure.

IMO, Ti definitely has its place in RC. It's a nice material. Strong, as we all know, and the low scratch factor is a nice bonus.

As for what parts I have in mind, well, we'll just have to see. No sense in bragin' around when I'm not sure yet if I can manage it. But I will sure post my results here.
I found Ti raw material to be rather expensive, and I guess that's why we don't see it too often in RC applications.

One thing I can say for sure, I love my Ti skids on my Maxx, and the center shafts of my first Revo also seem to pretty strong yet light.

Yeah Serum, I'm sure we will have something to do when I finally make it to the Netherlands, mill or not. But good to hear anyway. Tools at home are nice.

Gustav, I'm sorry but I have to disagree with you there. Aluminium is widely used in all sorts of planes, including the most modern fighter jets. I can't believe your trying to claim that not one piece of aluminium was used on Concorde -that's argueably one of the most ridiculous things I've ever heard. Aluminium is an extremely vital material in the world of engineering - used FAR more extensively than titanium.
Aluminium has been kicking around for so long, engineers know so much about it that nowadays, and rather than using it as a pure metal they can combine it with carbon fibre and complex plastics (skins of planes). Aluminium and carbon fibre are used extensively in F1 car engines, and also in the chassis.
I agree with you about titanium being a very respected material in the world of engineering, but to pass off aluminium like you did is not correct. Aluminium is the most common ore in the earths crust so whether we like it or not it is here to stay, and as time goes on we will discover more and more that can be done with it.

Hope I didn't cause too much of a disturbance! :)

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.

I simply never said that!

You are quite right to say Al based alloys are widely used in F1 engines (but i doubt there's any HE30,7075 etc that we use).The materials are governed by the sports regulations,not something NASA have to deal with.

This is interesting,http://www.newsonf1.com/f1regs/2006f1materials.htm It's the 2006 regulations for engine materials.Not as simple as saying Al this or Mg that.

Papa.., bring on the popcorn..

nah,i bored of that now,no need for popcorn.:007:

I'd like to know what Daf has planned.

On the subject of aluminium,anyone know the best way to bond it.Araldyte?
And also bonding titanium to aluminium.I know they bond aluminium in aircraft all the time,and the elise chassis is bonded so it must be possible.Any thoughts?
