Some of you may well be aware that I am a complete novice newbie to the world of large scale RC's, however in my search for the best of the best products, I came across a company called Zoni Racing, who offer Titanium products, I'm sure your all fully aware!

I see that they once offered a Titanium chassis, so I have had a long talk with Mike from Zoni Racing, and although he/they no longer produce a Titanium chassis, if I was to resurrect and re-introduce a Titanium chassis what would be the general consensus ?

Yes I understand it wouldn't be cheap, that said it would be a buy it once, in comparison to 2 maybe 3 stock, Aluminium or even Carbon Fibre chassis !!

Yes the Titanium chassis would be heavier than an equivalent Aluminium, that said, a Titanium chassis would not need extra bracing at the point of the front kick up!

I am just looking at all possibilities with an open mind, and as I'm new to all this, I value all your opinions, thank you so much.

Not worth the hassle or cost. Titanium or not a 30-40lb car hitting a non moveable object at 40+mph everything is going to bend. The idea that it won't need bracing or bend is a myth. This is the reason why they are not being produced in qty's. Several people have done this in the past and it's just not a cost viable option for the baja. Unless you can find a way to bring the cost down significantly!
 
+1 Mike.
There're quite a lot of 'Ti' aftermarket parts for smaller scales.
I've a lot on my E-Maxx, with Flextek arms, which can bend a lot - see Flextek videos - and (dare I say it!!!!) Integy skid plates and bumpers.

Needless to say, the Integy parts bend and scratch quite a lot - I had a high speed glitch kindly filmed by Paul B I think at Deeside (RIP) just before I switched to 2.4 GHz - the bumper was quitebadly bent, but did straighten.

I believe a lot of so-called Ti is one of the many alloys, as Al, where 6061 and 7075 are often mentioned.

It would depend on the quality, but your engineering expertise could certainly select that which is most appropriate.
I believe Mike will have encountered one of the many alloys.

It would be interesting, but most of us barely cover the costs imposed to maintain our rigs in good presentable fashion ...

Perhaps you could look at options and advise?
Al.

PS Looks like your boy is going to run away with the Turkish this weekend Adrian!! :D
 
The ally chassis' are more than capable and easy to straighten if they do go out of shape (talking FG here as not had any other models!!). If titanium adds weight it would be a big no no for the racers and as Al says the bashers probably wouldnt want to spend extra on the chassis preferring to bling the bits you can see. How much would you be looking at by the way??

That will all depend on the amount of interest, it will certainly be more than a CF chassis!

I will do more a lot more research on this subject and see what I can come up with to an alternative, there are many many alloys, and the 1 commonly used is the aircraft grade 7075 T6 and this is quite a soft alloy.
 
Its the flat design that makes them weak. Maybe you could look at incorporating more stiffness rather than a complete change of material - or both??
 
what car/truck are we talking about here?

i know for onroad stuff, you don't always want too stiff. i run an fg sportsline comp chassis, its 8mm aluminum, its hard to imagine bending the thing. it still has some flex to it, and depending on the surface, flex can be a good thing. a stiff chassis will make a car more predictable on a very smooth track though. the fg evo has an 8mm chassis, and it uses chassis braces that are held in with 4 bolts, you can remove the bolts to adjust chassis flex.

From what I have read so far, it seems to be the front kick up that's the vulnerable point ?

The way to get strength into flat sheet pressings, is to work bead roll channels in.

If anyone has a scrap alloy chassis they could donate, so I can study it closely that would be great, that would then save me buying a new one!

The HPI Baja.
 
You might struggle to do it on 4mm without it being over sized. The kick up is weak due to the reduction in section and there are no cranks on the edges due to the suspension mounts etc. Most fit a 6mm ally brace plate cranked to the kick up angle and fixed to the under side of the chassis to beef it up. Its a simple fix & seems to work well enough.
