Run a larger pinion if you don't want to spend too much yet. Stock kit pinion is made from soft aluminum anyway and won't last long on a high power motor and will chew up the spur gear eventually.

Hey guys , used your suggestions on here and ordered a TT02 Motul Autech Kit, just need the batteries, saw these on amazon , think they would work? (sorry cant post links yet)


Zeee 5200mAh 7.4V 2S 50C Lipo Battery Hard Case with Deans T Plug for RC Truck RC Truggy RC Heli Airplane Drone FPV Racing (1 Pack)

Those look good. I believe they should fit in the stock battery tray without issue. If you're running the stock Tamiya ESC remember you'll either need a plug adapter, or you'll probably want to solder on a Dean's (T-plug) to the ESC. My apologies if this has already been covered previously.

I used these;

Revamping some cars for my sons to play with outside.
running 17.5t on a 88/53.
i have 2 sealed diffs with metal gears & 2 normal plastic ones.
wondering what I should do for diff locations & thicknesses of oil/grease.
should I run the sealed units in the front with thick oil or run them in the rear with a 5k oil & thick grease in the plastic diff in the front.
Just fooling around outside .

Install the sealed gear diffs with 2-5K oil in the rear and the other ones with spool like behaviour filling in front.

Hi guys,


So I've got my standard TT-02 car which has been set up as a rally spec, and all I've done so far is install ball bearings, which made a lovely difference.

I want some more speed now though and I'm not sure exactly what parts I'll NEED to achieve this (bearing in mind I'm a proper newb with this stuff)


This is what I'm looking at so far:


22T Pinion

High Speed Gear Set

Tamiya Super Stock BZ, RZ or TZ motor (not sure which one is best)


Would I need to buy anything else or would the above be ok for now and plug and play without anything else?


Also, this is used just for fun only, nothing competitive or anything like that.

Have some nice woods around my area and just want to thrash though them.


Thanks guys :)

The kit supplied pinion should already be the 22T, so if you want a bit more speed and don't want to change the stock 70T spur gear then go up to a 23T, 24T or 25T.

The Torque Tuned motors are quite decent and I tried the black Sport motors as well as a lightly tuned Lightly Tuned 28T motor with replaceable brushes and really didn't notice any difference.

Maybe best to get tires with better grip for dirt rally use.

Thanks Steve!

I’ll drop the pinion then.
Still think the high speed gear set is worth is though, that’s 68T I believe.

I believe the high speed gear set gets you a blue alloy shaft and spur gear adapter that lets you use more traditional spur gears.

Sorry if this has been asked before, but is there a list of parts that are compatible with both the TT-01 and TT-02? I am gathering parts to rebuild my TT-01 and keep running across more TT-02 parts than anything else.

Very little, if any parts are interchangeable between these two kits. Tires, rims, wheel hexes, shocks, motor, pinion gear, bearings/bushings, maybe the dogbones.

Awesome, thanks for the help! I figured it probably wouldn't work but thought I'd ask.

the TT-01 has been around for ages and there is an almost unlimited amount of upgrades out there. There are even several chassis upgrades for the car. You still end up with a slow TT-01, but just one that costs three times the original price.

Yeah, I just bought the full Yeah Racing aluminum upgrade kit for it. I know it's a ton of money to sink into an old floppy chassis, but the TT-01 was my first RC car and I want to rebuild it into a shelf queen.

The Super Stock motors are a step up from the torque tuned or sport tuned, I was pleasantly surprised when i put one in a Top Force as I liked the look of the brushed motor in an older car. You may run into problems with the TBLE-02S though, it overheated in my Top Force so I switched to a HW1060. If you have the TBLE-02S then look at a cheap 13.5T brushless motor instead, performance is similar but the ESC can handle it and it has the bonus of no brushes that wear and need replacing.

The big advantage of the high speed gearset is you can change to 48p gears which are easier to get. If you get an adjustable motor mount as well (yeah racing make one) you can then get any gear ratio you want, so it is a good upgrade.

Personally my TT02 get bearings and I run them as is. Mine all came with oil shocks, I would probably buy oil filled dampers if they didnt come with them in the kit, otherwise they are good to go. No point in spending heaps on them

Very informative, thank you!

I've got the supplied TBLE-02S ESC so may look at some 13.5T Brushless motors instead.
Would I need any special battery to run a brushless motor, or would my standard 3000mAh NiHM battery be ok?

Also, If I'm just using it for fun, is there really any benefit to me adjusting all the gear ratios?

I've been looking at oil shocks too as I reckon that should improve the handling quite a bit.
Not sure if I should get the standard 55mm ones or bigger though, as not sure if larger ones would fit properly.

My way to go with a TT-02 "just for fun" :

- Ball bearings all around
- high torque Servo Saver (Tamiya 51000 for example)
- TBLE-02S with brushed motor (torque tuned, sport tuned, Carson Cup machine or similar)
​​​​​- high speed gear set with 64 t spur and 29 t pinion for decent speed
- oil shocks (Tamiya CVA or Yeah racing 55mm) for better control
- maybe the blue aluminum center drive shaft (just because it looks cool)
- a radio set with adjustable End points for steering is useful to go easy on servo and servo saver. Tt-02 does not need much servo movement for max. Steering angle. If you don't limit servo movement, you can kill either servo or saver.
- no need to go for the fastest and strongest Servo.
Someting with 0.1-0.15 sec / 60deg and about 5-10 kg torque is more than sufficient.
​​​​​​
Doing so, costs are limited and fun/ durability accordingly maximized 😁

Thanks buddy.

I've got a Radient RS-HT201 6.5kg servo which does quite well, and have adjusted the end points on my radio too, to prevent damage to it :)
So I'm going to look into buying a new motor, high speed gear set and oil shocks.

It definitely needs to be faster, the torque tuned Tamiya motor just lacks some punch.

Torque tuned motor is plenty capable and has plenty of torque. If you pick up the yeah racing motor mount, high speed gear set, 64 pitch gears (say 78/48) and bring the final drove ratio down to 4, you will notice the Toque tune is plenty fast!

I’m building up my TT02 as a rally spec car for use on a fairly bumpy buggy track, I notice tamiya sell the Super Mini CVAs and the Mini CVAs. Does anybody know if the Minis will fit? I’d like to get the bigger shocks on if possible.

Or, if they won’t, is there a taller shock tower available, tamiya or third party?

fdr of 4 on a torque tuned will kill it in one or two batteries. I killed 3 of them in one race day and that was at 4.2. The car went like a rocket but got way too hot and demagnetized the motor. This is also on road with a properly shimmed and smooth drivetrain. Off road will probably be worse. I’ve found the sweet spot with the torque tuned for speed and longevity is with the 64t spur and 28t pinion both in stock gear pitch. Puts you at 5.9 fdr.

Outdoors, loose diffs, it's a preference thing but I always ran ceramic grease in mine.

TT02 Rally Suspension
 

What is more important is shock travel. The suspension cannot articulate more than the Super Mini CVAs, and if you needed it to have more down travel, you can always put on the longer shock eyelet ends.

Also, just today I finally decided to remove the little plastic bump on the lower a-arm that stops the suspensions downward travel. Removing it increased it the perfect amount! I originally thought about cutting the lower bump off the upright, but I'm glad I went this route instead.

HI,
I just built a stock TT-02RR. I got the newest Protoform C8 Corvette body for it. The wheels are too narrow for the body, but it works okay.
Is there a way to make the track wider? I was trying to find off-set wheels but came up with nothing.
+
Does the TT-02SR have a wider stance?

Has anyone noticed how hard it is getting to find RC car stuff?

SR is wider because it uses a different(more racing oriented Suspension). If my memeory is correct, tt02sr uses 5mm hexes whereas tt02 uses 8mm to achieve the same track width.

And yes, this pandemic makes alot of things harder to get.

Is your Corvette body 190mm or 200mm width? (you'll want a 190mm width body ideally, but if its 200mm you can still work w/ it).
You can widen the track width of your car using wider wheel hexes. Your kit comes w/ some in various sized widths (I think), otherwise you can order wider ones. Stock kit is usually 5mm width, you can get wider wheel hexes which will offset your tires.

Also, are you using the kit wheels and tires? they may be a bit too narrow looking for the body you chose. Most kit wheels are 26mm (I am guessing that is what you have)? Corvette's have wider tires in the rear, ...not sure what your using your car for (bashing or racing), but you can check out or think about putting some of these on your 'vettte (they are wider than the stock wheels):
https://www.amainhobbies.com/protofo...kaAnRCEALw_wcB

Note: you'll have to get a set for the rear which are 31mm and a set for the front which are 26mm

There are probably a lot more options for wheels/tires as well in wider sizes.
hope this helps

You could try these.

https://www.tqrcracing.com/shop/prod...asp?p_id=10270

also Tamiya (and other companies) make wider wheel hexes that you can use, just measure the ones you have and go from there, Just make sure you can still tighten down the wheel nut.

The kit came with two wider hexes but the axles are too short and the nuts don't go on.
Thx for the tips!

Tamiya make a wider axle for the standard tt-02 (TAM51529) you would have to buy 2 (only one long axle per pkg) not sure if those axles will fit on the RR though.

The wheels and tyres that come with the TT02RR are 24mm wide inside of tamiya's usual 26mm and im pretty sure are zero off set compared to 3mm off set on all other TT01/TT02

The Ferrari wheels came and although they are wider they don't appear to be offset outwards much.
I also bought tires for TQ Racing only to find they don't fit the rims. They are for the racing trucks (semi's). Don't know what to do with them.
Looks like I wasted $50 here.

What 1/10 scale TC's actual are 190mm wide? I got a TT-02SR and I'm not waisting my time on it if it will look like crap.

The problem isn't likely only the chassis, it's partially due to the Protoform body actually being 193mm wide. I've included the specs from their website below.

Length: 17.68" (449mm)
Width: 7.6" (193mm)
Wheelbase: 10.1" (257mm)

Like previously mentioned, finding the necessary wheel hex width, spacers, or wheel offset (or any combination) is the only way to typically get it perfect. I've personally had great success with 3Racing hexes, along with their spacers to get it perfect.

Wheel hexes:
https://www.tqrcracing.com/shop/prod...13&s_maker_id=

Wheel spacers:
https://www.tqrcracing.com/shop/prod....asp?p_id=2263

I'm not familiar with the TT02RR axles, so if getting longer ones isn't an option, deeper offset wheels might be your only choice.

I finally purchased some proper oil shocks and the high speed gear set.

Had a little blast today and the Yeah Racing shocks with the super soft springs were excellent. It’s eradicated all bounce that the pogo suspension gave.

The high speed gear set made a minor difference.
I do want a faster motor still, the torque tuned just doesn’t have enough power.

Also, I’m struggling to keep the car in a straight line after making turns.
As you turn the wheel and let go, the car still wants to go in that direction, until you turn the wheel again.
Are there any upgrades I can purchase to get rid of that and improve the steering, or at least reduce the effect?

Thanks :)

Webarno,
Regarding your steering issue, I would first check to see if there is bind in the steering assembly. Second, I would check the servo saver. They can get sloppy at times. The Xray heavy duty servo saver is the industry standard (IMO) and worth the $20. Third, I would ask about the steering servo you're using. Some don't center very well. Fourth, could it be due to binding in the drive train?

Thank you.

Can’t see any binding issues or anything like that. The current steering servo is the standard one that comes with the TT02 kit.

I've managed to break the kit servo saver due to my own fault ... anyway it's well known to be sloppy and contribute a lot to the problem you're experiencing. I replaced it with the Kimbrough mid size servo saver. Been working well so far for me.

Ordered my servo saver now :)

Can anyone recommend a decent brushed motor that I can just plug and play?

So I'm going to grab a TT02-based Mustang or 911 as soon as they're in stock anywhere in the US - I've started ordering some hop-ups in anticipation, including the TT02 super mini CVA shock set (54753).

I was surprised to see the instructions have you build the front shocks with 3-hole pistons, and the rears with the 1-hole - making the rear damping stiffer than the front. This seems like the exact opposite of what you'd do with a full-size car, so I looked at some of the other Tamiya instruction sheets. And they're all over the place.
TT02R builds all 4 shocks with the 2-hole pistons, #400 oil
TT02RR builds like the hop-up part: 3-hole fronts, 1-hole rears, #400 oil
TT02D builds all 4 with 3-hole pistons, #400 oil
TT02S builds all 4 with 1-hole pistons, #900 oil; but they're also the TRF shocks if I'm not mistaken

So, every TT02 version that comes with oil dampers tells you to build them differently OOTB.I get that dampers are a tunable part, but is there ANY consensus as to what the best starting point is? Not even Tamiya can make up theirs minds, it would seem. Car will be driven on unprepared asphalt (parking lot) or tennis court type surfaces 99% of time (bashing/practice/fun running), if that matters. Looking for grip/racing handling, not a drift car.

I would ignore the S and Drift Versions. S has completely different suspension and the Drifters maybe do have other requirements as a racer.
So, we only have R, RR and Set 54753 with latter 2 have similar setups. R setup is not that far away, so you can go either way.
As often, starting on middle road is not the worst, so I would go with 2 hole piston and some 500 oil for the beginning and rebuild if necessary.
