Couple questions....
 

Hello, has anyone used wheel hexes TAM53056. If so how thick are they in MM? I want to get some for my new TT02 chassis. I'm hoping they are 6MM thick. Second question: has anyone used a Hobbywing quicrun 1060 for their brushed motor? If so do you experience the much talked about limp mode? I want to run a lipo battery but don't want to worry about over discharging the lipo with the stock tamiya ESC. Thanks

Since I focus on odd speed runs and fun builds, I've been getting excited with this warm weather finally getting here. That being said, here are some pics of my Big Brushed Motor TT-02. I finally had time to trim and mount the new 795 motor in place of the 775 motor I was running. I will have a bit more torque now as well 1000kv instead of about 830kv. There are also spools in the diffs both front and rear, now. I've managed a 52mph with 6s so far. It has been an interesting build. If it can get past 60mph I'll call it a success and probably bring it out to bash every once in a while. It sounds so smooth with the big motor directly connected to the diffs.

775 vs 795 Before trimming the you could see that not only was the 795 motor a tad longer, but so was the shaft. It wouldn't fit the couplings I've been using this way.

After some semi-careful trimming, the bigger motor fits!

This is what it looks like ready to drive. This set-up got me to 52mph on 6s. I tried these larger tires with the first motor in an attempt to get more speed out of it. There wasn't quite enough torque to maximize my speed like this. That was part of the reason for the larger motor. I'll be trying different tires to find the balance I need as I get it back on the road.

Testing the first set-up. It was easy to see that even with puttied diffs each wheel was gonna spin at different speeds. These tires were all taped and glued. I imagine they'll need retaping again before being used for any high speeds. I be trying foams on the next runs.


Wish me luck!

Metal diff gears???
 

Does anyone have a part number or part numbers for metal diff gears front and rear for our cars?? Thanks

why do you want them? Would have thought very much overkill.

51144 FWIW though.

Metal drive components
 

I'm looking for the same metal components drive line that the TT02R uses. I found 3 out of the 4 I need. I found 50823, 50883 and 50597. I'm lacking the metal cup joint that goes into the diff cases. The part # in the manual is 19804237. Nothing comes up with that number. Any help??? Pics of what I've found.

You can try Tamiya 54477. They are the metal drive cups that fit into the gear differential. But it is listed for universal drive shafts. It should still engage the dogbones properly.

You can use TT01 differentials in the TT02. They have metal internal gears but with 3 spider gears instead of 4.

Edit: if you decide to go with TT01 diffs, use 53790 drive cups instead of the TT02 ones. The TT01 drive cups have a metal shaft that connects the left and right side outdrives.

​​​​​​Thanks.... I was thinking the same thing. I mean how different can that end of the dog bone and universal actually be?? If they don't work out what is the harm in using the stock plastic drive cups??

New Tamiya ESC coming soon.
 

Did everyone here about the new ESC tamiya will be including in the tt02 kits??? It's the tble-04s and it's a slight upgrade to the tble-02 in certain areas. It has a low and hi battery cut off voltage. The low is 5.6v and the high is 6.2v. I wonder if the high cut off is enough not to ruin a 2s lipo. That means it's 3.1v per cell. Is that still too low for a lipo??

In my opinion 6,2V is too low as cut off voltage for 2S Lipo.
As always, ESC is monitoring the pack voltage and not the cell voltages. It may happen that the pack discharges unbalanced and one cell is already way below 3.0V (not good!) and the other one still above before cut off kicks in. I would like to see a cut off voltage of min. 6.5 or better 6.6V to safely (kind of) use Lipo batteries.

Ok....got it. Does Tamiya make a lipo ready ESC??? If not I'll just go with Hobbywing. Another question: what ESC do they use in the TCS spec/novice class when a lipo is used with the stock brushed motor?

Tamiya does not have an ESC featuring a Lipo friendly cut off voltage. They are all build to use LiFe or NiMH Batteries.
But you can use a dedicated Lipo warner instead of anorher ESC.

Time to build!!!!
 

Well not exactly yet....I finally got to order my TT02R from Towerhobbies. It has been out of stock like FOREVER everywhere except from Tamiya USA and I didn't want to pay that price. I just sold my Tekno eb48 2.0 that wasn't being used because the local tracks near me are always closed except for big races. So I decided to get a TT02 and have some fun whenever I want, I don't need a dirt track for that. I eventually want to start club racing with it too. My driving skills aren't the best and my knowledge of on road racing is limited so that's why I skipped the high dollar chassis's and got this. I used to race on road back in 2007 and really enjoyed it. A major plus is no dirty car to clean. I'll post pics as soon as I start my build. Cheers

Tamiya TCS spec/novice class
 

What batteries and esc do they use in the tamiya TCS spec/novice class??? I'm waiting to get those items until I find out what is the most popular used in that class. I really want to use lipo batteries but don't know again what is used in that class. Thanks for the advice.
