The inner (or left) servo mount is located below the prop shaft, so it needs to have a lower height than the right one.
You also have to cut away the half of left
​​​servo mounting flange to clear the prop shaft. Kind of weird...

Hi... Michael,

Thanks.

Just picked up one of these, a Mustang GT4. Haven't raced RC in 20 years, but needed some at-home stress relief and this fit the bill.

I'm never going to race this thing, but I added bearings and oil dampers because plastic bushings and Tyco friction "shocks" just hurt me on any car that looks this good.

Only other upgrade I plan on are tires. Kit slicks are slippery and I can tell they're going to wear fast too. What tires would you all recommend for parking lot bashing? HPI X pattern radials seem to be gone, I see a ton of no-name knock off brands (no idea if there are hidden gems buried in these), and Tamiya options seem OOS or hard to get everywhere. I'm looking to stick with 26mm width, to use the kit wheels.

There is a set of 4 tires with inserts from Ride RC:
Ride 26mm
I did not use them up to now, but I think they are worth testing.

Anybody know what part # I need to use these metal diffs in a TT-02? The plastic diff housing (outdrive cup?) that comes with the kit has four holes so it doesn't fit. I've got all the other internal and prop shaft gears I just need the diff housing.

If you live in the US, you can get them pre-mounted from Gravity RC for $25 a set:

Repost

Im not sure if either of those fit properly but it looks like Tamiya are releasing a TT02 specific aluminum servo mount (54977) so it might be worth waiting for

In the official Tamiya hop up parts catalog for TT-02 chassis Servo mount 54090 is listed for use. 54090 is right hand Aluminum servo stay of TB-03.

Are they from the DF02 buggies? They look like it. I use them in my TT02B and just needed the diff housing from the DF02 and the outdrives, dogbones etc all worked fine with them. I just had to file down the diff pinion gear which was easy to do. Its a really common upgrade for the TT02B with brushless motors.

I don't know the part numbers without searching, but the Gravel Hound and Plasma Edge were models on the DF02 chassis.

You’ll need Tamiya 51008 differential internal gears from the TT01. This will allow you to use the stock keyed outdrive cups. You can’t use the TT02 differential internals because they have 4 planetary gears laid out in a cross. This ring gear has 3 screws and will need the 3 internal planetary gears laid out in a triangle.

For the diff housing, you’ll need 51004 also from the TT01. You still have the issue of the plastic pinion gear driving the steel differential gear. Which may not cause issues initially, but might wear out that plastic gear sooner.

I'm not sure where they are from, I got them with my TT-02B kit. I bought it used and it came with a bunch of extras. Thought I had everything for these metal diffs but I didn't notice the different hole pattern.

I have the 3 metal internal planetary gears laid out in a triangle and the metal pinion gears (propeller shaft gears) so I'm set there. 51004 is exactly what I was looking for! Thank you.

They are from the DF-02.

Paint, finally.

Hi,
Need help from Tamiya experts here.
I am in the process of finishing my TT-02 & looking to spend on a set of TRF ALu Damper set.
I got confused by the choices available.

Based on my own study & research, below are my findings:

(A) TRF Damper set (53571)
From Tamiya -length when assemble = 61.5 mm

(B) TRF Special Damper Set (42102)
From Tamiya - more advanced than (A) 53571
My conclusion - length = 61.5 mm

(C) TRF Short Damper set (42273)
From Tamiya - 4mm shorter than TRF Special Damper (B) 42102
My conclusion - length = 57.5 mm

(D) TRF Big Bore Damper (42287)
From Tamiya - OD remains unchanged, ID is bigger, so 10% more oil
My conclusion - length = 61.5 mm

(E) TRF Big Bore Dampers + (42354)
From Tamiya - Compared to TRF Dampers, this set comes with better parts
My conclusion - length = 61.5mm

(F) TRF Super Short Big Bore Damper (42305)
From Tamiya - this set is 6.5 mm shorter than TRF Special Damper, 1.2 mm wider cylinder interior
My conclusion - length = 55 mm, not sure about the body OD.

(G) TRF Super Short Big Bore Dampers + (42353)
From Tamiya - this set is 6.5 mm shorter than TRF Special Damper, 1.2 mm larger cylinder internal diamater, better parts than (F) 42305
My conclusion - length = 55 mm, not sure about the body OD.

Questions:
1) If my findings above are correct in term of damper length, (A) 53571, (B) 42102, (D) 42287, (E) 42354 can be used on TT-02 with its original plastic damper stays. (/ shocks towers)?????

2) What about springs, do they all (A, B, D, E) share exactly same size of springs???

Let me know what you think.

Thanks
