I feel like my carpet setup got descent by the mains, literally changed the entire setup on the first 3 runs lol. I think it still needs more steering though to get the same laptimes as the XRay cars are capable of, I just had no practice before the race, so needed a smoother setup. I'll keep working on it in the next few weeks, and post it soon.

Arrow MRE Bottom Plate (Ebay)

The differences will be in the lay-ups. Currently (and this is only from stripping down some old tamiya carbon bits), I believe the chassis are made purely from longitudinal (0 direction) and transverse (90 direction) fibres. Also these are mainly Uni Directional (UD) fibres. The two outer plys are woven though... they are tougher (UD's can be easily split), but more expensive.

Now having a chassis made up from UD's in the 0/90 directions means that it will be very strong in thoose directions, try bending the chassis plate in only the longitudinal direction, pretty strong. Now twist it, and it's less stiff... as there are no diagonal (45/-45 direction) fibres....

My intention is to just play around with the lay-ups of the fibres, utilising some material we use at work that goes into the big wind turbine blades. It's pretty heavyweight (actually a bit heavier than I'd like... but gives enough plys to play with) UD fibre mainly in the 0, and 45/-45 directions. Also, where in the laminate the fibres go affects how much they affect the laminate.

For example, if I was to make a plate with purely 45/-45 fibres, it would be very stiff when twisted (good for foams?)... and still pretty stiff longitudinally (although probably not as good as the current chassis).

So by experimenting with all these factors, I should be able to make a chassis plate that is the same thickness, but stiffer, or thinner and the same stiffness, or just simply exactly the same as the current one.

So thats the intention... just need to get some woven fibre for the outer plys.... and get hold of the CNC maching company for cutting costs.
This ebay seller has one : Vellrip's eBay Store

Hope this helps Ed.

Ok gentlemen. I need a little help. The car I will be running will be using the Tamiya Suspention mounts. I am not sure how many different ones there are and what the differences are. I see there is a A,B,C,D and E. I also see there is a XA,XB,XC,XD and XE. I also notice there is a 1 printed on the block also. Like 1 XA. What do all this mean? I did print out the chart on THard.co but I am still a little confused.

those are the degrees... each labels like 1A, 1B, 1X etc corresponds to its own degree..

Print yourself up the Toe Blocks spreadsheet at tryhard's site: http://www.thard.co.uk/excel.html ...it kind of explains them all and what toe/width combination you get when you put differnt blocks on the car.

Simply, the blocks marked with a 1 are from the 415 range of cars, if they don't have the 1 they are 1mm higher and from the Evo4.

Blocks they are quite simple, honestly.
They range from widest to narrowest

E, D, C, B, A, X, XA, XB, XC, XD

and between each block is 0.5deg difference in toe-in.
This method also allows the adjustment of track width, without changing the toe setting.

Ie. a combination of XA/D gives 2.5deg of rear toe-in, as does XD/A. However the XD/A Combination results in a narrower rear track.

HiH
