RC Perspective's Red Headed Stepchild - TT02 Budget Build

Recommended Posts

So somewhere in between spending too much money, and spending too much money, there sat the opportunity for a piecemeal build.

I had already built this TT02R - 

And hadn't yet decided on this build - 

But I wanted a rally TT02 build. You may have figured out by now that sometimes I can't make up my darn mind :lol:

So with a BUNCH of leftover parts from the TT02R build, I ordered the 1991 Audi V8 TT02 kit (58682), and the WRC Lancer Evo VII body set (50927).

Not really much of a parts list for this one.

1991 Audi V8 TT02 kit

WRC Lancer Evo VII body set

TT02R Dogbones and cups

used cheapo JR servo

TT02R aluminum driveshaft and cups

TT02R aluminum motor plate

Yeah Racing aluminum steering

Ebay 13.5T sensored brushless/Tamiya TT brushed motor

GC301 gyro

Tamiya Rally Block tires

Some other random odds and ends.

Sadly I have no pictures of the build process. But I do have pics of it completed and other progress. I used some things I learned in the first build. Like the Labelle 106 in the gears, graphite lube mixed in with silicone bearing oil, the turnbuckles on the top of the front hubs for slop removal from the steering, etc.

Next to the TT02R

I started out with the Torque Tuned motor, as I hadn't gotten the brushless yet.

After its maiden voyage,

And all cleaned back up and on road tires while it awaits a body.

The First Body

I figured I should get some practice and knock some rust loose before I get the WRC body I ordered. So I got to work on the Audi body. Decided against the livery, Cause I like a clean, stock looking car. I taped the side moldings because I was going to back with black as the secondary color. In hindsight I wish I had taped the front ones as well. Oh well.

Started out with TS Metallic Red,

And backed it with TS Black and the smoke for the windows. (You all know the feeling when you are about to peel that protective layer off),

And finally, shiny shiny,

Not many decals without using the livery,

Added windshield wipers, cause I had them already,

Found it to be a hoot to drive on the dusty street! Drifting all over and just burning up those tires with the stock brushed motor. Absolute fun!

The Second Body

So when the WRC body I ordered finally came in, I was ready to get to work. Full livery too :D

Looking right at home on the chassis.

After paint but still with the film on,

And next to the TT02R, which got the Audi body to abuse,

PXL-20211111-134400627.jpg

Getting started on the fun part! Couldn't find the matching wheels for the body set so I got as close as I could,

This one was actually quite enjoyable to do the livery on.

Finally got the brushless motor in, so in it went!

The 13.5T was really, really quick off road! Didn't take long to start wearing the body :lol: I also upgraded to a Surpass Hobbies servo

PXL-20211210-132932933.jpg

Also got my dust and dirt cover in!

PXL-20211229-015421250.jpg

Added a few holes for the fans and glued some screen to the cover to keep the debris out. Tested in damp sand,

There was some dirt by the steering, but other than that it worked great!

As much fun as I was having with the off-road TT02, It didn't stay off road for long :lol: Turns out the dust cover also works really well for the rain too!

As I'm sure you noticed I downgraded back to a silver can brushed motor. I had to steal the ESC for the drift build. This was around the time I also started messing with the 3D printer seriously, and designing some of my own stuff.

I never really did a proper cleaning after running it in the rain, so some of the bearings could use a little TLC,

And added a few small touches,

20220525-214746.jpg

20220525-214757.jpg

Then I painted the barrels on the 2 piece rims in TS black, and used TS black as a primer on the inserts, then used PS metallic red to finish it off. I love how they came out!

And that brings us to today. I've decided that since this body is already pretty beat up, that I may start weathering it and making it look rusted, with some mis-matched panels and etc. We will see what happens. We all know how it starts :lol:

Alright!

Been working on this TT02 a little bit lately. After bashing when I painted the wheel inserts red, I rather easily broke the front splitter off pretty quickly. So I added some support to the mounting posts. I've now jumped the car and bashed it pretty hard and it hasn't broken off yet! Added to designs on Thingiverse - https://www.thingiverse.com/thing:5386254

20220626-135833.jpg

I also went back and revisited mounting flints on the chassis. Turns out a crawler shock mount with a slight bend works perfectly for this. I added a fine thread M3 screw and a star washer, as the vibrations from the flints against the road will loosen these up rather quickly. I use a dab of superglue where it mounts to the chassis, and some loctite on the M3 screws into the flints. With an ideal bend, it'll only spark when the suspension completely bottoms out, just like a real car would.

20220622-170424.jpg

I also started weathering on the body. Initially I have used some PS Black to make a "new" front quarter panel. Unfortunately (or fortunately for 1:1 Audi V8 owners), there are almost no pictures of rust on these cars for me to base some body rust on. One little spot behind the rear doors was all I could find. So I'll have to get creative and maybe just use pics of other cars, and guesstimate where the rust would occur on this one. Which isn't really hard to do watching where the dust and dirt builds up more.

20220701-181932.jpg

Another big improvement that makes it much more enjoyable to drive. The Yeah Racing steering setup has quite a bit of slop in it. With a Kimborough (spelling?) servo saver its highly doubtful to be the source of erratic steering. I know I don't have the best servo in this thing right now, but it also shouldn't be the cause. It's all caused by the slop in the steering setup. Erratic off-center steering, commonly caused by a worn servo saver, is the best I could describe it. So I used a couple Hot Racing SCX10 end links, and a spacer with a few shims, to add a link opposite the steering bridge to keep everything square.

20220703-092044.jpg

From the steering arm up, M3 set screw, Threaded ball, HR end link, M3 screw. 

Resting height

20220703-091750.jpg

Full compression

20220703-091808.jpg

Full droop

20220703-091816.jpg

Now, you point it, that's where it goes. Unless you give a little too much throttle that is :lol:

I could probably do away with the standoffs and 3D printed support now. I'll test that out today and see.
