TT02 ?

[speedy_w_beans]

Just saw on tamiyablog.com that 58560 is supposed to be a 1/10 Ferrari 458 on a TT02 chassis. TT02 has some question marks behind it, so it's not confirmed, but this seems worth watching. My hope is for tighter suspension and steering, and new sealed diff cases so they can be oil filled.

Anything for them to finally retire the darned thing

Good riddance to it , Never liked it . Hope the TT02 is carbon fibre of sort & different all together .

How bad was the tto1 , wow . Even the drive shaft had to be changed from new , very bad design .

But it was cheap , But too cheap . That if you got one & it's your 1st RC , would you keep in RC ?.

That's my 2 cents worth , This is by my experience with it .....

If a TT02 comes out, it will probably remain the entry-level chassis. In other words: I don't expect to see reinforced plastics and the least amount of metal parts possible.

From a perspective of the RC enthousiast it's indeed not much good. However, looking at statistics many of these cars would probably end up never being upgraded, and a bit lot also not being used after a couple of runs anymore. So from the perspective of price, environmental impact (people will chuck one away as is, so the less different materials - and in particular metals - the better) and usability for average target group, it is very understandeable.

I know, Tamiya's prices are not that cheap compared to RTRs from other brands, but I think that's down to mould and material quality and branding reasons. IF what I said about Tamiya's considerations for environmental impact and target group is true, then I don't expect to see ball bearings. Steel ball bearings don't fit in a view biased to environmental considerations, plastic ball bearings are probably too expensive to use in a car that needs to be so cheap. A very similar view would apply to shocks. I think we are not considered to be the average user for a entry-level car... and for that they have the hop-ups or higher spec cars!

PS: This does NOT mean I'm expecting the TT02 to be a bummer. Unless they move it away from being an entry-level car the spec might not be way up there, but it should be interesting to see how good a car they can make of it!

I had a TT-01 as my first on-road car, and it was fun to use for non serious bashing / racing. They're great if you just want to bomb round a car park with a silver can with a few mates, but they're no good if you want to take your racing seriously. But they are an entry level car to get people interested in RC, and are not intended as a serious racing machine. It's a bit like panning a sand rover or a grasshopper because they are not competetive racing machines. As an entry level RC the TT-01 is worlds better than either the sand rover or the grasshopper, with 4wd and double wishbone suspension all round. OK, it suffers from a lack of adjustability, and the shaft drive layout causes some horrendous torque twist problems when you up the power, but as a base model it's pretty good for the money.

I think the TT-02 will be the same basic design, but maybe with redesigned front suspension to add some adjustability to it (Maybe similar to TA-05 front upright system ?) and a few other refinements such as an aluminium centre drive shaft out of the box.

Either that or it's a complete redesign. Will be interesting to see what pops out.

[speedy_w_beans]

I sure hope Tamiya does something much improved with the TT02. There's a fair amount of competition between the 3Racing Sakura Zero S ($102), Associated TC4 Club Racer ($125), OFNA JL10e ($104), and Spec-R S1 ($118). The TT01R Type E ($130) is not competitive with these other chassis' features and performance; a TT02R needs to fall in line with these street prices, features, and performance in mind...

The sad part is they could just rearrange the batt position and add the coat hanger prop from the TA01 and make it a better car. I really have no idea why anyone still makes the batt down one side, motor down the other configuration any more. Batteries have never been heavy enough to counter balance the motor and electronics - and with the advent of the even lighter LiPo tech, it makes even less sense.

[qatmix]

I imagine it will be very similar to what is there already. The TT01 is Tamiyas most successful chassis, it is a great entry level rc car. The handling is pretty neutral until you start throwing in a pretty hot motor, its versatile and most importantly its tough. The Sakura / Spec-R etc are better chassis to start racing with, but they wouldnt take the amount of abuse an eager 12yo would deal out when playing with the car on the street.

The TT02 will be developed to be an entry level car, strong, easy to repair and neutral to handle. Hopefully Tamiya will change the integrated bulkheads to become separate, so a 'Pro-Spec' carbon chassis upgrade would be easier, to allow beginners to slowly spend up to get a good club level race car. I doubt the battery position would change, although it could be down the middle as Tamiya is definitely into that concept atm(TA06, XV01 etc)

As an aside, if you run a stock'Skyline spec' TA02 against a stock TT01 on a track you will be left well behind. The car is not as good at handling, the suspension geometry is well off.

Personally, I'm very interested to find out more info if it really is on the horizon.

Have you taken into account that electronics can be offset? A driveshaft or belt doesn't need to be in the centerline of the car. It's this approach that they use on competition tourers to make a decent weight balance from left to right, and it's no rocket science incorporating that into the design of even the most basic entry level car.

And though the TA01/02 are nice, sturdy cars, their design it outdated: They have more gears (=lower drivetrain efficiency), a floppy main driveshaft, higher centre of gravity, a tub not compatible for use with modern stick packs, etc - It must have been a very good car back in it's day, and still a decent daily driver, but it's uninteresting as a replacement chassis for Tamiya's RTR and entry-level tourer.

The link doesn't lead to a TT-02 anymore. In fact I can't find it on TamiyaUSA anymore. Hmmmm....

I have a feeling that it was a misprint - I'm sure that a product as significant as a TT01 replacement would have been leaked well before making it onto TamiyaUSA. We'd also probably have seen it at one of the recent trade shows.

Still, it is interesting to discuss what we'd all like to see from a TT02 when one is eventually released. Me, I'd like to see something very much in line with the spirit of the original, but with more scope for suspension upgrades. Having become frustrated with racing an expensive and tempramental Yokomo, I started racing a TT01 at a local informal parking lot club, and found the cost-to-fun ratio far more to my liking. I hope it's replacement doesn't change this.

I'm fine with whatever approach they take to improve the balance. The specifics aren't very important to me so long as they make it better. On the second point, I was specifically speaking about the driveshaft not replacing the entire with a TA01. I'm sure we can all agree that even flimsy coat hanger prop shafts are better than plastic ones.

[MadInventor]

As we're talking about what seems now to be a 'possible' replacement, here's my ideas for an improved model.

1. Sort out the torque steer. This could be done be mounting the motor transversly and then running the prop to the front off a bevel gear, and retain the simple crown wheel and pinion arrangement at the front. (Think hotshot layout rear end drives TT-01 front end (Not the hotshot diff though, re-use the metal gears used in the thundershot/tt-01,etc), this gives maximum simplicity for the number of gears with this motor layout.) Also, lose the dogbone centre drive shaft and replace with a unit with CVDs at both ends and a good solid centre component. It would be necessary to do this in order to have an rear output shaft offset from the centre line driving a front input shaft on or close to the centre line. It would also be possible to offset the front input shaft to one side as well by putting the gear teeth on the outside of the crown wheel, this would minimise the angle the CVDs would need to operate through.

2. Split the gearboxes horizontally like the df-02, but lose the DF-02 method of fitting the centre shaft from under the chassis. Remove the tops off the front and rear gearboxes to remove the entire centre prop in one go. This makes maintenance much easier.

3. TA-05 front uprights. Retain parts compability where possible with previous cars, so that existing hop ups can be used.

4. Allow the use of adjustable camber.

5. Make the battery area large enough to accommodate a 3S LiPo

Let the speculation begin!!

[qatmix]

TXt-2 mentioned on that list as well, although probably a typo

[atf300]

TXt-2 mentioned on that list as well, although probably a typo

isnt the TXT-1 discontinued ?

[MadInventor]

isnt the TXT-1 discontinued ?

I believe so, that's why I've started stockpiling them off ebay whilst the second hand price is good

[alfagta]

well , not quite speculation , more of a wish list ,

get rid of the stupid 'in moulded' arm mounts on the suspension arms ,

go over to a standard C hub arrangement on the front end, the ball joint front end that the 01 had is simply daft and doesnt meet the design brief of the chassis being 'an introduction class car'. it only introduced systems that are not used on any other tamiya kits , it should have been an all moulded car that had its geometry and build/construction method taken from the TRF cars.

the friction dampers really need to be forgotten, the mini cva damper is perfect for the tt0 cars and would take no new production tooling as proven with the TT01D ,

a stiffer plastic for the tub (i doubt they will use a grp plate ) to help the car drive in a straight line when a better motor system finds its way into the car,

the motor mount in the existing car is annoying and ill conceived and simply not needed in a touring platform , although i bet my life that they still use a pre meshed set up,

bearings , doubt it but we can hope,

all metal drive shafts and out drives ,

cross pin key for the diff pinions as they can strip out far too easily (unless they go belt drive)

for what its worth, i dont know why tamiya went for all the silly ideas on the 01 , most of them just made the car more awkward to work on and wore out quicker , not to mention how much harder it was to drive the thing, the tl01 was a far better(and faster on the track) car , the 01D with the few mods it came with transformed it into a far more robust and useable platform ,

what i think we will actually get is a variation of the 01E with different suspension arms and a lipo ready tub and metal motor mount,

Its funny, I used to race a TT01 in our local silver can "plastic chassis" class, only mods were TakeOff CS27 tyres, ali driveshaft, 55/25 spur/pinion set and eventually oil shocks after I bounced off the track a couple of times !, whipped TL01s, beat Ta05's, TB's and HPI's, nothing really could touch it until the better guys got TA05's, then I had to work for it, but the little old TT went round corners like it was on rails, steering slop and all, in tight corners, I just backed off the power, hung out the tail, power on and go, predictable and consistent.

I like them, they are a good basic car, built to wear different bodies, the factory set up is good and it can provide an enormous amount of fun, but they were light and never designed to have a lot of power, that is when you move up to the TA05

Not easy to work on though, having to dismantle the car to get to the spur gear is a pest!

My 2c, I would expect a different design but still using the same basic architecture ala M01/03/05 and M02/04 (M06 went rear engined!)

[qatmix]

The TT01 does have a very neutral handling base with slower motors, that is one of its strengths. The slop actually aids that. The issue only comes if you want to race it against better chassis, it soon becomes a disadvantage as the large amount of neutral set-up is hard to overcome and tune against. A racing chassis will be responsive to subtle tweaks to allow the best possible speed on the track.

As mentioned before, I doubt they will loose this characteristic. However brining a few more things inline with other cars (kingpins, suspension mounts) would be a nice move.

Now that's a chunky "Plastikbomber"! I'd like to see how it performs in comparison to a stock TT-01E.

[B.M.T.]

Appears that the same basic and extensive driveline upgrades need to be done.

I could not believe the TT01 when it was released. The TL01, albeit a big plastic log, with Tamiya upgrades could be competitive. I raced mine in 27t stock as a dare some time in the 90's (TA-04 Pro's were the hot Tamiya at the time) and won the first race of the day. Since that was so awesomely unexpected I didn't enter race two... But the TT01... I tried the same test, bought every practical Tamiya upgrade (sunk about $300 into it) and it was hopeless, and that was in 540 class. Sure I could get the gearing high enough to be on par, but it was so heavy an inefficient, slow acceleration motor temps made it impossible to even stay on the same lap.
