Does anyone know if a #51000 Hi-Torque Servo Saver would suit a TT-02? The distance between holes on part D10 from the kit appears to be approximately 21mm centre to centre, whereas it seems to be less on the Hi-Torque Servo Saver?

Also, would #54121 HT Servo Saver Alum Horn have the same distance centre of hole to centre of hole as part D10?

I bought the hi torque one and it was a pain to build because of the clips you put in there. I believe you would have to adjust it appropriately with your adjustable turnbuckle?

Qatmaix can answer this one :P I'm using the stock one and have not had issues plus my TT02 is used purely for off road and I've done maybe 30 cartwheels with it. I just got t boned last week so we will see. My low friction screws both snapped in their threads! New tub ordered :cry:

Hey ATG,

I use that servo saver on three TT02's. The fit is tight but not hard to do.
An adjustable turnbuckle is needed as DJ said.

After stripping a servo once before I now use these all the time - I haven't actually used the stock setup.

Unsure on the alloy piece.

Cheers,

As mentioned, you can use a Hi-Torque servo save, I would recommend it over the std one. I like a 18mm horn on the servo saver, 3Racing make an alloy horn to fit onto the Tamiya Hi Torque which is 18mm high.

You can just use the plastic ones in the Hi-Torque kit, I would use the larger one (the one with 6 holes) and mount the turnbuckle on the top left and set that up to be straight. This is higher than the other setting and will give you all the throw you need.

I want to maybe gear higher at my track. Currently using 19/70 gear combo. Car tops out around half way on straight. Not sure if I should gear higher... If I want to get higher top should I get the 55/58 spur for the higher teeth tamiya AV pinions (20-25t)?

3/4 down the straight is a good place to have top speed, maybe just fit a bigger pinion?

I'm wondering if the bigger pinions will fit ok with the stock spur?

Yep you can go up to a 25t pinion with the stock 70t spur.

lifesaver!

Saved me a few dollars which I'm willing to do!

The 55/58 spurs you've mentioned are option spurs for a TT-01 chassis and not for this TT-02 chassis.
Perhaps with some modifications but they are not a direct fit.
It's better to buy the high speed gear set (part nr 54500) and you get a 68T spur wich allows you to go higher in pinions, up to a 27T (pinion set 26/27T with part nr 54228) and if you still need some more speed then buy a 64T spur (part nr 51356 and you can mount up to a 29T pinion (pinion set 28/29T with part nr 54229)

Hope this helps you.

Yeah I hope the max is the 25t because if I go higher, as you've said I'll have to get a new spur then another motor mount. I'm a bit of stinge! :p

Are any of you doing carpet racing? I've been told 32/34deg tires are the pick?

You don't need to get another motor mount, all those pinions i've mentioned are a direct fit to the standard motor mount.
You just need to mount them in another motorposition on the motormount, that's just the best part about this car.
I'm having a yeah racing motormount but so far i still haven't used it.

Me and my little girl running the TT-02 chassis on carpet but i always use tamiya tires.
I could recommend the medium narrow radial tires from tamiya (part nr 51023) or some A-type medium narrow reinforced tires (with part nr 53433, this will allow you to mount the tires on rims with an offset of 2mm.
This will make the car 4mm in total wider wich will give a better balanced car.

I'm currently using 6mm offset wheels with Ride slicks with LT inner. Just wanted a set of 32-34 deg tires... And didn't want ones with spec markings on the rim for the complete white out look. My tt02 ride height was between 10-15mm so I did roll at some points... It's under 10mm though could get more by changing the collar positions on the front and flipping the rear hub but I probably won't as I loctited the front knuckles :p

Got some thicker damper oil (400) so still quite a few more settings to play around with. Probably won't get the 2degree toe in rears even though I hear good things about it...

Hi, if it helps, I can say that our club uses Sorex 28R for carpet racing (XG-28JB - Sorex Glued 28R+JB+Revlite24)

Finally finished assembly of the TT-02D (which incidentally will not be used for drifting, but was purchased as it included bearings, super mini shocks and a sport tuned motor) and gave it a shake down yesterday at the race track. It felt promising after racing my usual car all day, and with some experimenting with settings I’m sure it will perform well.

I just used the anti-wear (AW) grease in the front diff and Tamiya grease in the rear (not sure if this is okay or if ceramic grease would be better in the rear – has anyone any thoughts on this?) to give a stiffer front diff action and hopefully more on-power traction. Also used hex drive screws rather than the supplied self-tapping screws to ease assembly and future maintenance. Other items used were low friction step screws (54409 and 54550), low friction suspension balls (54559), low friction suspension shafts (54395), aluminium motor mount (54558), high speed gear set (54500), long wheel axles (53410) to give an approx. track width of 185mm using 24mm wheels / Ride Re32 tyres (note, use gearbox joints 54477 with these universal shafts) and 2.5 degree aluminium rear uprights (54549), which were purchased with a 15% discount from Tony’s Tamiya Parts. Note that the instructions that come with these show upright A on the right of the car whereas it needs to turned upside down and fitted on the left to give toe-in and the appropriate ride height of approx. 5.5mm / 6.0mm for touring car racing.

Does anyone know what the difference is between the on-road tuned spring set (53440) and the on-road spring set hard (53163)? For example, are they the same length and will they suit the size of super mini shocks when used for touring car racing?
