well, I'd rather hear a press release from tamiya about this car, than read BS from wannabe engineers on this forum

Some of the guys on this forum are actual engineers and are more than qualified to pass comments on what they see, in fact a lot of discussion of what goes on in threads like these filter back to manufacturers so they can improve in future.

Also when tamiya release the car, they won't go into any great detail like what has been discussed above. So threads like these are really interesting. :)

We can all speculate on wear rates and transmission drag, but in the end until the car is released and being run, we are all just guessing. I will say, it is less complicated than a Schumacher 4wd transmission....

I'm an Engineer ;)


But what should be discussed is: Will this car outperform the DB01?

And i think the answer is the same as the comparison between the the TRF511 and the TRF502X. Both cars performs the same but different. DB02 will be faster in the hands of one driver while the DB01 will be faster in the hands of the other driver.

Anyone know when this is likely to be released?

Are you being ironic?

If we are to take manufacturer marketing speak as sacrosanct why can't I make the A-finals with my box-stock re-re Tamiya Hornet? The box says its a "1/10 scale High-Performance RC Car". It must be because I cannot drive properly I guess. No manufacturer has ever fed the market some BS (especially in a press-release) to stoke up expectations and desire in the wallets of prospective buyers right? Nah, they wouldn't dare, they only ever tell it straight.

As already posted, the proof of the pud will be when the thing is out in the market and being used. Until then its all just speculation anyway.

And there are plenty of "wannabe engineers" on here that may not have a BSc but can give good advice based on experience. I'd rather listen to what someone who has used a product has to say rather than pay any attention to a marketeer/copy writer who probably has no real idea of what he is actually writing about (how many Reliant brand managers actually drove a Rialto for example?).

I dont hold a degree in mechanical engineering, but I do hold a patent with the US Patent Office for a high performance motorcycle air intake system that I designed, and I have built a plethora of R/C car, airplane, and helicopter kits.
Does any of this count?? :confused:

I do have an bsc in Eng (and business studies, joint degree) and I don't have a f***ing clue!

Does anyone have any idea of a release date then?

Next year, with a month ending in a Y...

Let me guess... It will be July? :D

I may by the way have (another) explanation for the choice of 4 aluminium gears. (Other than Tamiya's fetish for aluminium gears) :p

They could've done it with two steel gears, but this system is likely to be too heavy. If you use aluminium, roughly 3 times as light (and 3 times weaker), you could use 4 gears and still save weight. They may also be not as strong, but most of the difference in strength is covered by using the extra gears. Perhaps the two steel gears give an amount of strength they don't need, so they saw an opportunity to save weight by using two more gears and aluminium instead of steel?

February 18th release in Japan.
Mighte be here a bit earlier.

To my surprise, it costs much more than a DB01.
I only care whether the gear box cover of a DB02 fits that of a TRF502X.

Yen is way too strong atm. 40 % stronger than few years ago.
Thats why all the rc products from Japan are so expensive atm.

This seems like a very expensive price for quite a low specced car? or is that just me.

I hope the differentials aren't as poorly designed as those on the DB01 :(

I hope those are not the same shocks as on the DB01...

plastic fantastic :thumbdown:

It seems that the A parts of trf502x are the same as that of db02.
Dd02 released is a good news for somebody who runs trf502x that they do not worry that the A parts break and cannot not be gotten
