Bearings, servo saver, and front universals are all my track allows. Of course some take it over the edge but a lot of those hop ups don't actually make the car any faster. TT class just makes sense if your track isn't huge.

NorCal hobbies is a great place! I read that they just added a Stock Slash Spec class for their indoor carpet track-- if the demand is there, they might do the same for the tt02 (maybe try posting up in their FB group. I like the suggestion of only limiting motor- maybe limit to the Tamiya sport tuned brushed one that comes with the kits?). Does NorCal stock parts for the TT02?

I'm not a serious racer, though, I'm trying to learn, so I'd probably just want to show up for practice laps... maybe run a rookie class- I've never actually raced. I've been meaning to get down to NorCal hobbies for an on-road weekend. It's the closest track to me, but it's still a bit over an hour away, so finding the time at the right time isn't easy. I wish they just left the on-road track set up 24/7.

Took the TT02 out on 3s today. Did really well, till, well it didn't 🤣

Don't have much room to even do the 58mph it does on my road.

Actually, it's a Spec Slash class. Whereas Stock Spec Slash only allows changes to the pinion (and, maybe, a few other very minor changes...I'm not 100% certain), Spec Slash only requires running the stock ESC & motor, and tires. Anything else you want to change, as far as I'm aware, is "ok". Want to swap in the LCG chassis? Go for it. Want to switch our the (garbage) Ultra shocks for GTRs? You bet ya. Want to change the 2075 servo for something faster/stronger? That's also allowed. Want to replace the plastic shock towers with CF towers (of you know where to get them)? You can do that, too. It's not a 'sanctioned' class.

So this'll be the second time I'm having to rebuild the Savox servo LOL. It takes a rather large hit to break even with a solid servo horn. Ordered 2 rebuild kits this time.
While I'm waiting on that stuff I threw the new high speed gear set in the rally/drift chassis, and changed the gearing from 19/70 to 23/64 for a pretty decent increase in speed without sacrificing the torque if the torque tuned motor. Took it out and ran through a whole 5200mah 100c 2s drifting on the dusty pavement out front with some cheapo rubber tires. Super fun. Can't wait to finish the decals on the Evo VII body!

You may want to consider a servo saver.

I know, in building my TT-02, I'll be giving the servo saver find in the Traxxas 4Tec 3.0 a try. It's adjustable, similar to how a slipper is adjusted...you can make it as "loose" as you want, of completely tighten it (essentiality, turning it into a servo horn). If anyone else is interested in trying it, I don't have the Traxxas part number (I removed it from one of my two 4Tec 3.0s), but a quick search should pull it up

I know what you're referring to. But, I found only 4-Tec 2.0 the servo saver didn't help much to save the stock servo. When I replaced it the stock servo with a cheap metal gear servo it worked well. If it will fit on a TT02 with a good servo it might work well. I've never tired it in any other car.

If it doesn't work (because of it being mostly plastic), there are aluminum versions from 3rd-party sources, such as Integy, RPM, and Hot Racing (NOT that I'd ever recommend anything from the first two). The HR part is TRF48SH25.

Might put a Kimbrough on the rally car. Haven't found a good servo saver otherwise and tired of the steering not centering with a servo saver.

Solid on the speed run car without question.

When you hit things going 60+ a servo saver isn't going to save anything 🤣

Kimbroughs have always done well for me.

Yes, it will. However, you might have to look real hard to find the "saved part". 🤙🏽

That's what I hear about them. Gonna give em a try at some point.

Ain't that the truth 😆

I talked to Shawn a bit about this class, as I am interested in trying to push for a similar class in my area. The idea behind the hop-ups is that it gives people room to grow with their car. As we know, these are not the best handling kits right out of the box, so the drivers will get to slowly improve the performance as they grow in their skills and can afford to. The emphasis of this class is fun. I know everyone has all of these engrained, sometimes sour, feelings about spec classes and fairness and all that, but the intention is to have a fun class that is affordable for beginners and allow them to grow into the class at their own pace. If a seasoned racer wants to drop a bunch of cash on all the top-of-the-line parts just to dominate in this class, I think that just reflects a bit poorly on them. I don't think it's worthwhile to limit a newcomers potential for gradual growth, just to level the playing field w/old pros. There are also some ideas in place to handicap such a driver at the race director's discretion. As they say, don't allow perfect to get in the way of just good enough.

I think a TT02 Spec class is a fantastic idea. I personally would allow for any Tamiya TT02 hop up. (TCS style) Reason being, none of them are a huge game changer. Eventually overtime all cars would end up catching up with same hop ups. Eg if the fast drivers are running the Type S arms, eventually the rest will catch up.

I would however disallow non Tamiya hops ups, just to keep things more aligned. Again none of them would give a huge advantage, with the exception of the Yeah racing motor mount, which gives greater gear options.
