that's great to hear. Makes me feel better about my choice of ESC. Did you solder a cap to the battery leads??

I recently bought two. One is in a Tamiya M05 with a torque tuned motor. In all 3 qualifiers and the 3 finals at my last meeting it went into limp mode whilst doing the warm up laps. In the actual runs it only did it once on the first lap of the last final. It never did it off the line ie stationary to full throttle, really weird. Never once had an issue with my ancient tamiya esc. Every time if I just sat for a few seconds it then seemed to go back to normal

The other one I put in a TT01 with a team powers brushed which is quicker than a torque tuned and I presume more power hungry, only gave that a couple of runs but no issues.

Going to put the M05 one into nimh mode and wire a cap in if it does it again, if that doesn't work then it goes in the bin. I wish I had researched them first as there are so many reports of it. I just bought them as I wanted a cheap waterproof esc with lipo protection

it seems it is a shot in the dark on wether you get a good one or bad one. I may just go with the new Tamiya Tble-04s. It's low voltage cutoff is set at 6.2V. I know it's alittle low for lipos but races are only 7-10 minutes long. I don't understand why Hobbywing doesn't correct this known issue. Raise the price and make the Hobbywing 6V/3A and fix the limp mode issue then they would have a winner on their hands for a brushed ESC. Can you use the Hobbywing 1080 for racers?? It states it's for crawlers.

There is no incentive to make "race worthy" brushed esc's , when the international bodies that sanction RC competition have long ago moved on to brushless.
HobbyWing makes perfectly affordable and capable brushless esc's that are better suited to competition. Don't paint yourself into a corner with the limitations associated with older technology.

I'm not trying to paint myself into a corner. I want to race in the TCS in the Spec/Novice class and that class has to run the torque tuned motor or silver can stock motor. So I'm limited on what ESC I can use. If you can help me out with some suggestions that would be great.

The stock Tamiya ESC is a good choice.
If your budget allows, I seriously recommend considering Tekin FX esc's... Even though they are marketed as crawling esc's, they were fully developed long before crawling was part of the market. They are a full option brushed esc that is very suitable to race spec. They are also super tiny and compact, making them really awesome for fitting into tight spaces and keeping your center of gravity low. Back when I raced Tamiya mini, they were the ESC to have.

Additionally, Tekin RS esc's can be wired for brushed motors and set to brushed mode. Something I can't do with my HobbyWing Xerun esc's unfortunately

I've been researching brushed ESCs and can't justify spending $100 on an ESC for a $115 car. The Hobbywing 1080 is the one I've decided to go with. It's only $41 per unit which isn't bad plus has all the features needed in an ESC. Thanks for the help and advice

Do TT01 bumpers fit our TT02. I ordered a bumper from the TamiyaUSA website from the TT02R spare parts list and the pic is not what I was sent. I can't seem to find the correct part number for the bumper that comes with the R version of our cars.

Good luck, but the tekin RS series are worth the extra cash without being stuck on either brushed or brushless modes....

Tekin RS is 10+ year old design, that’s why it still has brushed / brushless mode. The current RSX / RSX Pro is brushless only.

with respect to HobbyWing, ten years ago you could argue that Tekin was a better esc, not today. The HW XR10 Pro / StockSpec are outstanding ESCs.

Tekin is still a good product so don’t get me wrong there, but their appeal is not what it used to be. I seldom see anyone at track running their ESC. Majority run R1 or HW

Even though, no one asked...….The one other thing I like about the old Tekin ESC's is that you can rewire right to the solder posts. The HobbyWing brushed esc's terminate the wires inside the plastic housing. So you're stuck with the rainbow leads unless you crack the case open. Don't accidently cut the motor and battery wires too short. Spliced leads look hack

My experience with stock spec racing classes is that you would want to find every incremental advantage you can to reduce weight and lower center of gravity...one of the ways we did this was by reducing the connections between battery and motor as short as possible.
Does the TCS Spec/Novice Class dictate that the stock connectors for the motor be used? Or are you free to wire directly to the ESC?

I am curious to know how the 1080 brakes perform in the TT-02. Personally I'd never use it for racing, but it could function just fine for me in my Tamiya parking lot play things.

It appears that the foam bumper that came with the TT-02R kit is Tamiya Part# 52128. It is listed as part number SP-1218 in the parts list at the back of the manual. If you look at the description of this foam bumper, it shows that it should fit TT-01 kits. I would assume that it should also fit TT-02 kits since it was included with the TT-02R kit. Here is a link that shows which kits this bumper was included with...

While I have not owned every variant of the TT-01 or TT-02 it appears that all the foam bumpers should be interchangeable between the different versions of the cars. In fact I just pulled off a foam bumper from a base TT-02 kit and tried it on a TT-01E kit and it fit just fine onto the plastic bumper.

Tamiya makes several different size foam bumpers for the TT kits depending on which body kit was included. On kits that didn't include a body, Tamiya typically included a smaller foam bumper. If you are having difficulty finding the exact foam bumper that came with your TT-02R kit, you might have to modify a larger Tamiya TT foam bumper to work with your body. Foam bumpers are fairly easy to cut using basic hand tools.

Here are examples of a Tamiya TT foam bumpers that are being sold through A-Main hobbies...

Here is a Tamiya TT foam bumper similar to the TT-02R bumper being fulfilled/sold through Amazon...

If you were sent the wrong PLASTIC bumper, I am afraid that those aren't interchangeable between the TT-01 and TT-02 kits.

The PLASTIC bumper for the TT-02R kit is Tamiya Part# 51528 (SP-1528). The PLASTIC bumper would have been a part of PARTS BAG B in the kit and there would have been 2 included. you should be able to purchase the plastic bumper for the TT-02R kit from various sources such as TamiyaUSA, Tower Hobbies, Horizon Hobby, Amazon, various online sellers, or possibly through your local hobby shop. Many local hobby stores are happy to special order parts for their customers as they are already receiving weekly shipments from major R/C suppliers.

Here is a link to the part on TamiyaUSA's website...

I hope this information helps.

*stares at the sparkling new XR10 Pro/G3R in my TT-02R* ...Well, I've screwed up this time, haven't I?

Just joshing around, lol. I totally get where you're coming from... it was a hard pill to swallow spending more than twice what my new T-02 kit cost just for the motor/ESC. The way I saw it though, if I'm already spending X amount for a nice middle-of-the-road option, why not spend just a bit more for what I really want and can grow into? For instance, if I decide I'd like a more track-focused chassis in the future, I can pop my electronics right into that one and be good to go without having to buy any of them twice. At least that's what I've been telling myself, anyhow!

Hi
Anyone want to sell their TT02RR roller please PM ?
Thanks
