TA03R TRF Kit

TA03R/RS TRF

Basic Info:

TA03F-S and R-S has a wheelbase of 237mm

TA03 Chassis width according to Tamiya is 185mm for all TA03’s

The David Jun model is in short a TA03F Pro with a bunch of hop ups. It’s basically the TRF version of the TA03F. Also, as far as I know, the David Jun model TA03F comes with a set of front C carriers that have a different amount of caster, and are specific to the David Jun model. They either are one degree or three degrees, the stock caster is two degrees. The stabilizer bars are a different stiffness, and are silver in color. Also various parts are gold anodized.

The Aramid belts are skinner and thinner then the stock TA03 belts, which are wider and thicker. The Aramid belts come in various colors, Red for TA03F-S and TA03R-S, TA03F as black, green and blue. The yellow TA03 belt is made by Tech Racing. With Aramid belts it isn’t necessary to run a belt tensionor.

Stock pulley size is 16T front and rear. The kit also includes 15T pulleys (two pulleys).

Torque control units are supplied with aluminum pulleys. TA03F kit comes with 15T and 17T pulley while the TA03R comes with 14T and 16T pulleys. Basically the torque control unit is two different sized pulleys, a 15T and a 17T, the standard 03f pulleys are both 16T, you can use these pulleys to give more torque(15T) to either the front or the back and less(17T) to the other, the unit also includes a one way shaft.

Black gears are plastic while the white (cream) gears are delrin. The cream gears have a fine tooth pattern while the Black gears are a coarse pattern. Cream gears have also been said to be quieter then their black counter parts.

The gear boxes starting with the number 5xxxx are all grey color.

Most needed parts right out of the gate:

TRF Dampers – These will provide a better ride and far greater adjustability over the stock oil or friction shocks that come with any TA03 kit.

Bearings – If you TA03 comes with bushings, ditch them for the better rolling ball bearings. These will give you a smoother less friction drive train will also giving you a tad more run time, cause of the less friction.

Sway bars – Keep your TA03 level during drifting.

Other noticeable parts:

Tobee Craft Rear Spool – Locks the rear wheels together

Low Mount Shock Towers – Provides extra ground clearance if needed

Front Universal Joints

Center One Way Shaft – Acts like 4WD when on throttle but acts like 2WD when off throttle

Ball Differential(s)

Conversion Guide:

TA03F to TA03R, you will need:

- TA03R front gearbox (B Parts, 50743)

-TA03R bumper tree (E Parts, 50717)

From TA03R to TA03F, you will need:

- TA03F rear gearbox (B Parts, 50699)

- 2x 16T pulley or belt tension (w/15T pulley)

- 50698 TA03 A Parts (motor under guard)

Miscellaneous Information:

If you’re looking to remove the tub chassis and to get the flat chassis, you will need the FRP conversion kit for the style of TA03 you have. There are a few different kits out there that are FRP conversions.

The TA03F FRP set and the TA03R FRP set are closely the same, minus the TA03R FRP set has a different top deck compared to the TA03F FRP set and that it also comes with other various parts to work with the motor gear box.

Also if you want to go to the Carbon plates you’ll need also the J part(s) which include battery stay and chassis blocks and other parts needed.

Optional:

- 53306 RC TA03F FRP Chassis Set

- 53358 RC TA03R FRP Chass.Conversion (2nd choice, usable for F)

- 53302 RC TA03F Pro Carbon Chassis

- 53261 RC Carbon Battery Plate Set - TA03F-Pro

- 53267 RC TA03 Ball Differential Set

Gears and Pulleys:

The TA03TRF and 03f pro run Tamiya 0.4 pitch gears NOT standard 64 pitch although it will work u should run a Tamiya 0.4 pinions.

Black = 48p [Tamiya 0.6 Pitch]

Cream = 64p [Tamiya 0.4 Pitch]

This is a steering modification that my friend and I use on our TA03s. It's awesome for drifting, and it really works. It's also really simple to do - 3 steps!! You can do it in about 5-10 minutes, and all it requires is a drill and a dremel or a grinder.
Start off by removing both front knuckles, and both steering arms from your TA03. Also, remove the tie rods from each arm, and set them aside. You'll need to lengthen them later on.

Shave off or sand away the small bumps that are on the interior edges of the steering arms that bump againt the front gearbox. This is much easier if you have the plastic arms instead of the aluminum ones, but you can shave off the aluminum ones too. It just takes more work. Removing these bumps will give you a couple of millimeters of travel in each direction. Make sure that it's completely smooth on both arms, so both of your steering arms travel the same amount in both directions.

After:

Here's a look at the difference between unmodified arms, and shaved arms. Note how much closer the ball end comes to the gearbox.

Drill a small hole on each of your front knuckles. Make sure to use a drill bit that is slightly smaller than your ball end threading. This will ensure that the ball ends will have enough mateial to thread into. You'll be drilling the hole in FRONT of the original hole. If you have regular plastic knuckles, then I recommend using the casting imperfection that is about a millimeter or so in front of the original hole as the drilling point. Make sure you drill the hole as straight as possible.

Screw your steering ball ends in the new holes. If you put your steering assembly back together, you'll notice that the front hubs are toed in much more than before you modified the front knuckles. Simply adjust your tie rod lengths to correct the toe angle of the front wheels.
Viola!!
Now your inside wheel (when turning) will have an extra 3-5 degrees of steering travel. That doesn't sound like much in 1/1, but on a 1/10 TA03, the wheelbase is short enough that it makes an INCREDIBLE difference.
For those of you who are familiar with real cars, D1, Formula D, and drifting in general, this is the equivalent to a very popular tie rod modification made by professional drifters. By subtley changing the steering geometry, you're changing the distance that the tie rods travel when turning, so that they pull the wheel further inward, resulting the wheel turning further outward. The outside wheel won't change too much, because of the way the steering geometry works. But when turning, the inside wheel tracks into the turn at a much steeper angle, allowing for tighter turning and higher angle drifting.
Here's an example of this steering modification at work, on a professional drift car:
