while i see some good points with this car, i wonder really how long those alloy rear unis will last with todays engines. while light , yes. how will they hold up ? long enough to Qualify well, then fail in the last 5 mins of a long main ? i hope im wrong, but with so many improvments, they , like the Alloy one piece layshaft ED , fragile !

What alloy units do you mean patto?

I got an email yesterday saying that it was the final report for the G4II so it musn't be to far away

the diagrams of the transmission show that the rear universals are now made of aluminum. I'm with patto too, I imagine its such a small gain in performance that it would be hard to warrant such a degradation of durability. who knows maybe it is a perfect place to shed some rotating mass but i see it as a questionable change.

isnt 7075 a strong type of aluminum alloy? its used in fighter jets and high performance bicycles.

rcrevolution, a high grade aluminum alloy will be stronger per unit weight then steel. so you are right in the sense that if you had a sample of each with the same mass the aluminum would be stronger. however aluminum is much less dense than steel so you would need to have a much larger volume of aluminum to achieve the same strength. That is why assuming the new aluminum universals are the same size, they won't be as strong.

If the pins in them are alloy aswell then it will definately be weaker. The diff out drives i'm assuming are made of steel so if you have an alloy drive shaft then the alloy will wear a lot more and quicker than the out drives will. They do look a lot thicker than the front ones though

Any word on a release date yet, i want to start a sleep countdown

ma the speculation around TM right now is soo tempting, we have this nice new car being developed, talks of someone being interested in striking up more distribution for TM here in the states, if all this went down, I would buy another TM product.

Only time will tell.

"concept"


If they decide to use alloy, it will be the first thing I'd change...

Want to lower rotating weight ?....why not use titanium diff gears and shafts

I had a FW05 with alloy shafts, lasted about 2 race meets before the pins started to move.

why not carbon fiber shafts...MUAHHAHA

Chiefy 707

I could understand having alloy option parts for those who can afford it for that extra little advantage come raceday. Keyword there is option.

Out of the box though I'll take hardened steel please.

Or is somehow TM is reading this to gauge what racers want, how about forged titanium? Or some kind of super exotic military grade ceramic. Ok Im kidding but hardened steel, really.

OK Styles, Bundy..

This is the setup Brendan & I will be using as our "starting setup" for the upcoming NSW IC titles....no doubts it will change, but after 3 or 4 clubbies where we tried everything else, we continually went back to this.

I suggest if you want to make this work, copy it exactly...just using bits here and there won't work.

We will be using the std G4RS without the WC kit...

Here we go...

Front.

Track width - 198mm
Shock oil - 450 cst
Piston - 2 hole x 1.2 mm
Spring - RRR rear (long) medium blue or Mugen dark blue rear ( long)
Top Mount - kit position ( 2nd hole out)
Caster - 3mm clips in front, 4mm in rear.
Wheelbase - std
Spool ( i.e. locked front diff )
Sway bar - flat ( softest )
Roll centre insert - bottom outer
Toe - 1 deg out
Camber - will adjust when we see tyre wear at the track, but start between 1 1/2 - 2 deg neg.


Rear

Track width - 200mm
Shock oil - 450 cst
Piston - 2 hole x 1.2mm
Spring - TM purple ( 1.5 mm )
Top Mount - kit position ( 2nd hole out)
Wheelbase - shortest ( 2mm spacer behind rear arms)
Rear diff - 30k oil
Rear camber link - we are using the alloy rear bracket ( like the one the G4s / G4+ rather than the plastic RS one ) , the position is the "down" which is similar to bottom outside on the RS one.
Outer hub shims - 4mm
Toe - 2.5 deg in
Sway bar - flat ( softest )
Camber - 3.5 deg - (again, will adjust to suit)

Protoform stratus
16/52 - 20/46


Feel free to ask any questions.


Bundy, I saw the pictures of the aftermath of your car going off line....

I hope you weren't using spektrum...

We mount our receivers on the transponder mount up the front, haven't had any incidents since....

Thanks Luis, it looks good How do your gears mesh? I thought the split had to be the same so that's why i've sticked with 16/51, 21/46.

Also what "mm" are the front springs, just so i can compare to the TM springs

I've also sent you a PM.

Great stuff

Offline yes... it lept the end of the straight, cleared the barrier and barrel rolled its way accross the paddock on it's way to the BMX track!


I am also going to have to check the condition of the Picco, might have stretched the conrod

they don't stretch, they snap
