Thanks

I have used both, the TA05 is vastly superior to the TA04, easier to build easier to work on and very fast out of the box,

although if you are not in the top 10% already it wont make that much of a difference.

How about you consider the price os the 04 TRF and the stock 05...

Can't compare this way.

if you are buying new, The TA05 plus a few hop ups is still superior to a TRF TA04,

Just did race my TA05 against TRF415, TC3/4, EVO IV, etc .. (plus just one TB02).

My car was looking more smooth and faster (in the straight) then almost everybody ...

But due to the my mistake, the car was little bit too low (4.5mm) and too soft, plus the heavy 3700 GP battery ... it tun out that I was a massive oversteering on the tight right turn ... and quite understeering on the fast right turn ... turning left was fine ! ... so I have lost a hell of time time spinning out of control in the two tight right turn on the tract ...

My TA05 did run very fine with GP3000 on the training ... for getting more hard to controll with GP3300 ... and a terrible car with GP3700 !!!

I don't see how I can compate with TA04R (here battery is free in TCS) .. that will use GP3700 ... and I will have to keep the GP3000 !!!

A TA04R cost same as TA05 stock ... (119$ both from eBay)

But TA04R does need far less hop-ups .... TA04R come with TRF suspensions)

But I fear that with the GP3700 and Tamiya TZ motor ... I do belive the TA04R is far faster then the best hop-ups TA05 ...

So I guess I did a wrong investement with my TA05 ...

PS: Let's hope the light weight reinforced TA05 chassis come as soon as possible out from Tamiya factory !

Interesting thread, as I'm actually comparing these two chassis for my next car as well.

I would assume that TA05 development will continue for several years, as it did with the 04... The 04 will phase out sooner than later now that it has been superceded, as will aftermarket development for it. While a stock 05 is currently comparable in cost to an 04R, and the 04R may be a bit better equipped out of the box, my guess is that the 05 will provide a better platform into the future. Then again, I could be wrong... wouldn't be the first time

e_lm_70,

I recently ran in the US TCS Nations (GT2 class). I tested with both the TA04 TRF and an optioned TA05 the Thursday and Friday prior to the race. The 05 was nearly a full second faster per lap than the 04TRF.

You have the correct chassis!

Such a weight imbalance from batteries can be helped by preloading the right springs a bit more than the left. That way, any sway to the right will be resisted more than the left.. I have to do that on my M-04 because the motor is mounted more on the left side than the right, and will actually veer right when accelerating without a 2mm extra preload because of the imbalance.
When you sit your car down, does one side ride lower than the other?

I'd say that the TA05 is much better than the TA04, just by design of maintenance and the freeness of the drivetrain. No need to pre-stretch belts . Sure, right now, a TA04 TRF by just being lighter with graphite may out-perform a TA05 in those cases, but as the '05 progresses, it will be way better just because it's a better platform to improve upon.

Why would Tamiya invest huge man hours not counting the money if they will just be designing a car that will be more inferior to a model that it will be replacing, its just like compairing a 414 to a 415 , an FK04 to an FK05,a 2001 5series bimmer to a 2006 bimmer, a newer design would MOST of the time be better, but I'm not saying an older one is not winnable , just my two cents.

Okay, Since I've got both the TA04TRF and Stock TA05, I'll give my 2 cents worth

...the 04TRF is lighter BUT has more drivetrain drag due to the belt layout, with the super free 05 belt layout, you could actually feel each and every motor's magnetic resistance in the "cruise" mode.

Fast forward to the present ......My TA05 is as TRFed as TRF possibly could. I would say the TA05 is a much faster, easier to work on and stronger chassis.

btw ....dun think you can put in GP3700 into the TA04 chassis.

I believe you are saying that you have understeering on entry and oversteering on exit ......Check your droop settings !

I tape my batteries onto the ta04trf. (removed the black plastic thingy) So i can bsically run whatever batteries are out htere. I have not seen a ta05 in my area, so I was definately eager to see if anyone's got the dough to buy both.

In this case, (since i hate buying hopups) i may wait for the TRF version of the ta05 to appear
