Poverty Drifter - Budget USA TT02 Build
After lurking here for awhile, I decided to finally register here so I could start a thread on this TT02.
Let me start out by saying, that yes, I know the TT02, let alone the standard, non "S" model, is not the greatest platform for drift build. I know it has very little adjustability, and I didn't realize just how more "toylike" vs hobby-grade it was until I started building it.
With that said, here was my rationale:
- Cheap: $140, the whole project is about being able to have fun while being as cheap as possible
- Brand: I wanted a kit and Tamiya is known for them
- Parts Support (Or so I thought): Tamiya has comparatively better parts support in the Midwest USA than any other asian brand (Yokomo, Kyosho, 3Racing would all require overseas ordering)
- Parts interchangeability: Tamiya has a long history of sharing components between models and I love to tinker...

I ended up getting the Carrera RS for $140 from Tower.
Total Cost So Far: $140

I did a box stock build to start out, before I tried any drifting, as it was also my first touring car.
Unfortunately I did not take many pics during the build.

I used a junky old Traxxas Link receiver and Solar D771 servo just to get it running before purchasing a proper servo.

After testing it on it's maiden voyage, I came away with two conclusions:
- The stock servo saver is absolute garbage - the wheels could not re-center due to the servo saver
- Driving a stock touring car on a Tamiya silver can (ok it was torque-tuned) is painfully slow and boring. 
- There are no RC on road tracks in my area, so I figured it was time to transform it into a drifter :)


The first thing I did was remove the stock servo saver. I replaced it with a generic rigid plastic horn. Now it was actually drivable.
Cost: Free

I then placed a large Amazon order to start the transmogrification. It was at this point I realized how limited the parts selection of hop-ups for Tamiya kits is in the USA, especially in the Midwest.

- I ordered a new body: A Hpi 190mm Trueno Coupe (I would have preferred the more scale Yokomo Sunrise Levin, but I didn't think it was worth double the cost and wait time)
Cost: $26

- Paint for the body: Tamiya PS-23 Gunmetal, I decide I wanted to do a reverse-"panda" scheme with gunmetal body and silver accents since I had a half-empty can of PS-41 Bright Silver lying around. 
Cost: $8

- An "aggressive" Sport Tuned Tamiya 540
Cost: $21

- 2 Pairs of genuine T-Drifts, I wanted to start out right, even if the knock offs are comparable.
Cost: 2 x $9 = $18
- 1 pair HPI 6mm offset C90s in white, I chose them because I liked the mmore than other Hpi wheels and I wanted it to ship from within the USA, because shipping on any cooler JDM wheels was cost prohibitive.
Cost: $10

Being the cheapskate I am, I decided to use a pair of cool looking vintage Ofna wheels I found in the bargain bin of my LHS, which I had lying around for a year.

The LHS owner told me he was ready throw them out!
Cost: $3

Total Cost So Far: $226

I quickly installed the motor. I had quite a team trying to mount the T-Drifts, I had throw the rims in the freezer, and the tires in mug full of boiling Keurig water  Lol

Mounting the body required some work. I had to flip the rear arms to get the wheelbase to line up and reverse the body mounting posts.
Here's a picture after I mounted everything up and trimmed the body:

[Image: HoIGU4sx-KPqTeETg5srPwwkv9JxWBNG46K-_v77...80-h893-no]

I ended up switching the Ofna 5 spokes to the rear, as it was already a handful for me to drive as a drifting a noob, and I read that a wider rear track increased oversteer, so I reversed that.

At this point (August 2015), I started masking the body, got half way done, then the project was thrown on a shelf for about 6 months because the school year began, only allowing me to work on it during breaks.

I have 2 about years worth of build updates to catch up on, so stay tuned for more updates  =).
In order to get some more steering angle, I dremeled down the steering limiters on the front suspension arms and knuckles

I also started shaving unnecessary weight where I could. I removed the rear bumper stub, and I replaced the front bumper cover with washers.

You can also see in these pics that the 6mm offset Hpi wheels are the right width for the shell. The Ofna's are too narrow. I think the MST 5mm offset wheels would be ideal and maybe 6 or 7mm will work with
some negative camber.

Here is a picture from when I finished masking the body. I used Tamiya 6mm masking tape for all the edges.

This was the final result after painting it:

[Image: K6zTqADtjNKnXyqCCcWrOoctQurS43OcLh3PWo8i...88-h893-no]

I was pretty satisfied with the end result, as there were no runs or bleeding, the only issue is some parts of the rear bumper were still a little translucent, but I don't care because it will get all smashed up anyways.
This is a fine job, it's what I'd call a "drift" for your buck.

After getting it all painted up, I spent  a couple months trying to learn how to drift. Unfortunately the stock Tamiya TBLE-02S esc crapped out on me so I used a Castle SV3 because the bullet connectors were the right size. However, I ended up needing a the SV3 for another vehicle so I swapped out the RS-540 and put in an old 2-Pole Traxxas Velineon combo. This added a lot more low end torque which helped with initiating drifts at lower speeds. I'm still running the stock TT02 gearing, and I honestly do not now if I should change it.

The next summer, in order to make the car more drift worthy, I decided to order a new servo. The Hobbyking Turnigy Trackstar TS-9xx series of servos boasted pretty good specs an d reviews online indicated they were pretty good, so I settled on a low profile brushless coreless one with an under .10 second transit time. Unfortunately it was out of stock so I tracked down the OEM, Alturn which started selling on Amazon. I ordered the Alturn ABDS 690HTG+HV. The servo performs as expected but the 25T spline is on the small side and has some longitudinal play. Alturn USA was kind of dodgy as a seller.

cost: $30

Total Cost So Far: $256

Since I just ordered a new servo, I wanted to protect my investment and not keep running without any form of servo saver. While browsing RC rtr chop shops I came across pieces from the new HPI RS4 Sport 3 on Dollar Hobbyz. Online reviews indicated that it wasn't a great car, but they did say the servo saver was decent. BAM! I ordered it right away since the whole steering assembly was priced a $1.24! Shipping brought the total up to $4 but I was still getting quite a bargain on links and bearings and other junk.

cost: $4

Total Cost So Far: $260

The RS4 Sport 3 servo saver was indeed quite nice for $4. As you can see below it is aluminum and adjustable.

Unfortunately it also is on the larger size and did not fit in the TT02 tub. I could have researched different servo posts to move the servo back, but I was determined to make it fit, and dremeled the chassis.

Since I received all the other parts for my $4, I was curious if they too would fit, and since the RS4 steering featured ball bearings and metal posts, I tried swapping it in. I had to flip the bellcranks upside down to make it fit, and I tried drilling new holes in the knuckles, to increase the steering, and because I had not other choice since I did not have turnbuckles. I also flipepd the upper arms around to give the car more caster.

[Image: LqywXuFLaBv1zr5IaApAO-033F37WrdLumTQcyvv...00-h450-no]

As you can probably predict, when I tested it, the car performed a lot worse. The RS4 steering decreased the angle of the inner wheel and there was now so much caster that the front would "jack" it self up when steering like a go-kart, which led to lots of spin outs. The car was barely driveable.
RS4 Steering swap: Failure

I quickly switched back to the stock TT02 steering arm setup.
