Default Time to build!!!!

Look what showed up on my doorstep today via FedEx!!!! I'm just waiting on the body and a few more upgrade parts then I will put it together. I will post pics along the way. This is my first tamiya kit in like 35 years. My first two rc cars were an original tamiya super champ and blackfoot. This kit brings back so many great memories. A time when rc cars were much simpler and a blast to drive. I'm crossing over from the competitive world of 1/8 e buggy were it's all about racing and winning first and enjoyment second. Time to relax and have some fun now.

I'm in a similar situation. My first RC was a Tamiya Grasshopper in 1986. I remember I was expecting the build to take me a month or so but I had it done on the first day. I didn't know of any tracks around me and the novelty of driving it around in a parking lot quickly wore off so I didn't pursue RC any further. I'm now in the middle of building a TT-02 '99 Monte Carlo Subaru. The only mod I'm starting with is some oil filled shocks. I suspect that the steering mod is going to be a must have but I'm going to try it stock first.

I can't qoute yet, but to answer jamsandolina's question: If you're looking for the steering post for the aluminium steering set then I think it's Tamiya 3454760. Since it's the same one used on the trf419x, I think you could also use Tamiya 13450752. This one has a hex shaped bottom which makes it easier to remove.

Default Servo choices???

Hello..what servo do you guys recommend for racing the TT02 in club racing??? I'm looking at two different Hobbystar lv servos. One is 109oz/.09 and the other is 139oz/.11 both of those numbers are at 4.8v because the Hobbywing wp 1060 ESC runs at 5v. I confirmed through Hobbywing USA. I have an off-road racing background. So my guess is with the smaller tires speed is more important than massive holding power. Thanks

Yes you need speed in the servo .. not high torque

Also be very careful of the Chinese knock off servos. They are NEVER close to rated speeds and torque.

I run Hitec servos in all my RCs. Fast, quiet, and not too power-hungry. I've never needed to replace one in 8 years.

Default Tble-04s ESC low voltage shutoff

Hello. I posted something about the new Tamiya Tble-04s ESC low voltage shutoff (6.2v) earlier and someone said that is too low. I've been doing some research and the Hobbywing 1060 brushed ESC has a two cutoff (6.5v) half throttle and (6.0v) full cutoff. Wouldn't the Tamiya ESC be ok to use since it's cutoff is basically in the middle of those two numbers. I'm afraid that if I get a Hobbywing 1060 it will start having the dreaded limp mode issue. The ESC is the last piece of the puzzle for my build. I'm running a Tamiya torque tuned motor. Thanks

i am assuming that the previous comments have been in mind with a 2S LiPo battery. you don’t want to discharge a LiPo below 3.2 Volts per cell as you might risk to damage the battery. With good balancing between cells, 6.5 V is just enough to let you know to stop immediately while 6.2 is already risky. If you want to use the Tamiya TBLE I would recommend to use a LiPo alarm set to at least 3.3 V per cell.

OK then that means the lipo cutoff for the Hobbywing 1060 ESC is too low then...right because it goes to half throttle at 6.5v and cutoff at 6.0v. Unless I'm understanding it wrong technically the car can still be driven until cutoff with the Hobbywing which is too low also. What ESC do the people use when racing in a Tamiya TCS novice class?? Do they use a lipo alarm also?? I'm alittle confused. Thanks

I was planning on running the stock steering assembly at first and then upgrading it after it likely fails but does it sometimes take out the chassis too. If so I can use the upgraded system from the start. I am curious about how well the stock set up works though.

All of Tamiya's esc's have a cutoff set for LIFE battery Which have a lower cutoff. I would leave it and just keep in mind of the cutoff. I have ran lipos on my TBL02S ( Which is the same esc pretty much with a different form factor.

Either keep in mind how long you are running, or get an alarm.

Ordering the Tamiya screwdrivers was very very wise. Well played.

That's the first two items I purchased with my kit. Lol
