Thanks, I'm going to do that...

So far, so good, I am building this rig slowly... Man, I love Tamiya kits. They really make you work for the build. The fit and finish so far is top-knotch.

So far, it's been as fun as my DF-03...

I would hate to take this thing apart for maintenance though!

What kind of power plant did you guys put in your TA05 v2?

10.5?
13.5?
17.5?

<10 turn (like 5700Kv)

???

I'm thinking of sticking the 4600Kv + Mamba Max system in there... I figure, the torque and rpm requirements are similar to the 4wd 1/10th buggy, except it probably requires slightly less torque because of the smaller wheel and being on-road...

I have a few questions on gearing in this car.

I have painfully pulled out my Mamba Max + 4600Kv motor out of my SC10 and in process of installing it.

I noticed that with a 70T spur (the one that came with the kit), you can only go down on the pinion gear so far before the motor screws hits the end (as well as hitting the spur).

What is a good gear ratio for a 4600Kv with the motor timing set to the lowest in the ESC setting?

In my SC10, I had it geared to a FDR of 13.8. I'm guessing I should stay within that range to not fry my motor?

Please help...

I want to change to 64 pitch spur/pinion. has anyone done this and which brand did you use.

I'm wondering that myself, I see Associated, HPI, and Duratrax making 64-pitch gears. They all *look* the same, but wondering if there was any confirmation on which ones work.

I have a problem with gearing this lower (higher FDR), with a 70T spur, and a 2.05 transmission ratio, it doesn't leave much of a range for the FDR.

Anyone know which 64 pitch gears work? The Tamiya 70T spur that came with it is obviously not the right one right?

Which motor and track size are you running. The guys where I run are at 4 ish FDR that means I need to go to at least a 30 pinion which is crazy for a medium size track. I am running 17.5 or 25t Tamiya black can.

I'm running on a medium sized track, it's a beautiful 7500 sq. ft. track, which is about twice as long as it is wide.

Right now, I have the Mamba Max with the Castle 4600Kv motor in it (the mamba max fits like a glove in that ESC area, almost like it was dimmed for that ESC).

And currently, the only two gears I have are the ones that came with the kit, the 70T spur with the 20T pinion, which brings the FDR of 7.19 to 1.

I'm not worried so much about speed as I am about frying my motor.

The 4600Kv was geared at about 13.3 in my SC10, but then again, it's not trying to turn those monster SC tires, but these cute little touring tires...

It's also not climbing any inclines, just doing S turns and chicanes...

Do you think 7.19 for onroad, 4wd touring is sufficient for a Castle 4600Kv motor?

You should temp your motor when you pull it off. You want to be in the 120-140 range. Right now with the 20t your geared for more power and less top end. You basically want to top out at about 70% down the straight away thats how I set my gearing up to start then go from there.

Yes, 64 pitch gears work fine(it's all I use in any onroad cars I have), & I've always had good luck with Kimborough, & I believe also RW(check the spur listings at Nexus Racing, they have plenty of good ones available & you can see what the RW spurs look like). And about motors, I've tried a 21.5, 17.5 & a 13.5 in mine, & it's handled them all very well. If anything, the car's felt MORE comfortable with more power, so I wouldn't worry about that much. Oh, & if you're wondering what spurs you might wanna try in 64 pitch, I'd suggest starting with a 96 & have a 92 tooth handy, that should give you good gearing flexibility for most tracks.....

Thanks Grizz. So it's safe to say that the 96t spur will fit in the chassis??

Yes the 96T spur works fine. That is what I am using (RW brand 64P)

Had a few options part installed on my ver 2 such as seperate suspension mounts, steering set, rocker arm set, pinions and gears. Am planning to get the Tamiya's option part front bulkhead from the ifs as that seems to be the correct fit. Does anyone knows the option part number for the rear bulkhead that fits the ver 2?

FX Racing

Does anyone know if 3 Racing makes a carbon graphite chassis for the V2? If so what other parts will I need to upgrade like bulkheads etc and has anyone had any luck with ceramic diff balls, are they better than the tungsten diff ball set? Thanks
