Do you mean the slots in the outdrives are really large or the outdrives themselves are meant for a physically larger "ball end"? I ask because I've not seen a TT01 ball diff but know Stock TT01 bones are huge plastic things. If it's just that the slots that are too wide use some driveshaft protectors/blades/cushions/u-pieces. If the gap is 3.5mm you can use Tamiya ones such as 51536 swing shaft cap.

First time running the R version. Ended up with blue springs all around. It was better than blue front springs/ yellow rear combo. I'm going to try yellow spring all around. Rear shock in inner hole and front in the outer hole. Getting ready for Pro Spec at the Tamiya USA track

Hello guys. My friend bought few days ago a brand new HPI RS4 Sport 3 and I instantly noticed that the chassis is very clean, with few wires left in view. I find my TT02 more messy. I reduced the lenght of the wires going from the battery to the esc and from the esc to the motor (except sensors wires). As I stripped my chassis to install the hardened lower deck, I'd like to shorten the wires going from the esc and the servo to the receiver. Can I cut and resolder them or I shouldn't do it? Thank you very much

You can get new pre-wired harnesses, pins, and connectors at an electronics/robotics place like Pololu:

When I was doing a lot of competition rock crawling, the receiver and ESC would be at one axle of the vehicle, while the battery and steering servo would be on the other axle. I would get an extension longer than what I needed, then cut it to fit exactly, and use new pins/connectors on the trimmed end.

Alternatively, when using multiple motors and ESCs, I would just trim the ESC control wires to about an inch or so, then use custom length extensions to reach the receiver wherever it may be.

While there are still some instances where you would need to go to the ESC pcb and physically solder new control wiring, most ESCs now use 3-pins and you can just get the right length harness or make your own (ideal if for various stand-alone BEC setups in larger scale vehicles).

Any recommendations for wheels for the Radial Racing tires? Trying to set up my son's TT-02 for an upcoming TCS race.

Part #s would be appreciated. Thanks!

Wish the weather would clear up so I could get some wheel time with my new TT02R.

Hello guys. As here in Italy spring is coming, few days ago my friend bought a HPI RS4 Sport 3 to bash with me. We did some bashing in a roller skating rink today. It has a smooth, dusty surface. We did also some drag races to compare our cars. My friend's rc has a 15T brushed motor, 2000mAh NiMH and 8.53 FDR. My TT02 has cheap chinese tyres found on Amazon (waiting for my HPI X Pattern to be shipped), 13.5T Trackstar combo and 5000mAh NiMH. I raced with stock FDR and timing set to the center mark and acceleration was quite the same but my car has a bit more top speed. Next I tried with 5.74 FDR and max timing but the result was the same, maybe a bit worse. I know I'm still noob but with lower FDR and higher timing I thought that my car would be even more quicker. I know my tyres haven't good performance but I know my car can hit about 45 km/h. So I'd like to know if changing something in my setup could give more traction

Your looking for radial type tires?
I have been using these with lots of success for my 10yr old son (medium grip asphalt track).

TowerHobbies.com | Associated Rubber Tires & Inserts NTC3 RTR (4)

These are inexpensive, ...they grip well.

I also switch between these and TC slicks. -various brands.

My son is running the Torque tuned motor w/ upgraded gearing ...speeds aren't insane so these get the job done well.

If your son is prone to hitting things, I would go with Tamiya's reinforced mesh wheel part #53336. I have several of these wheels and have never broken one.

I know the radial tires are 24mm and these wheels are 26mm, but they will work fine.

Thanks for the recommendations.

I have a couple sets of the #51237 Suzuki Swift wheels for my Mini. Do you guys think the offset will be ok for the TT-02?

Do standard sized stick (full length) lipo packs fit in these without issue?

Anyone using the +9mm Tamiya Hex hubs (part #54610)? If so, what axles did you use?

Yes absolutely.

Great. Thanks.

yeah, the outdrives are for the larger ball ends like the stock TT02.
