Sgt.Speirs‘ TRF garage (TRF414M, TRF417 V5 & TRF201)

Recommended Posts

Hello all,

welcome to my TRF garage. This currently consists of three TRF cars:

  1. TRF414M (see build log in the following)
  2. TRF417 V5 (>> start of build log <<)
  3. TRF201 (>> start of build log <<)

 

In the first chapter want to share the restoration and build of one of latest Tamiya on-road car in my collection:

The TRF414M

(Source: www.tamiya.com)


The TRF414M Kit was release in March 2001 under the kit number 49175.

About its pedigree there is following written down from Tamiya: 

„After several months of experimentation on the TRF414 chassis kit and a considerable amount of race participation, the TRF designers are proud to bring out an improved version of the chassis, the TRF414M chassis kit. The improvements focused mainly on heightening the efficiency of the drive train and increasing the cornering speed. The TRF414M Chassis Kit is sure to give competitive RC racers just what they need to win on today's track.“
(Source: www.tamiya.com)

I found also a summary here at TamiyaClub:
TRF414M CHASSIS KIT (limited release)

Normally I’m not so interested in TRF models, more in the TA family of the 90s. After a TA01, TA02 and TA03 are already in my collection, a TA04 would be the next one in the row. And the TRF414 as „predecessor“ of the TA04 would also be fine in the collection. 

The car was part of a hobby abandonment and was offered for 414€. But the price was more a joke from the seller and we agreed on a very good price. Maybe because I bought my Dyna Blaster one week before from the same seller :) 

The car arrived only with the manual (motor and servo are not worth mentioning).

So first was to deassemble everything and check for demaged parts.

dbe28342-2f1c-4142-9o4f7r.jpeg

The front suspension arm block of the front suspension was a little bit tricky due to the screw was worn out. But with the help of WD40 I could remove the screw without damaging the aluminum block.

I was surprised how few plastic parts are used for this kit (ball connectors not showed).

8f49275e-0221-4b86-bfuf2j.jpeg

 

Fortunately all aluminum parts were in good condition and only the lower carbon deck was used (full of scratches). 
Unfortunately the rear ball diff (with metal diff joints) and the front one-way diff were replaced by the TA04 Lightweight Diff Joint Set (TA-53480). Due to I want to re-built the car as close as possible to the original, I have to replace/find the missing parts.
Fortunately I found a shop in Belgium, which had a lot of the missing parts.

Currently I‘m only still searching for the A parts tree (especially the front bumper stay A4).

So let’s start with the build…

 

Step 1 - Attaching lower deck parts

Until now a great building experience and completely different than former TA02/TA03 builds…

…and this without blue aluminum parts :)

Lovely build and step-by-step journal 👏

So far it's looking very much like a TA04-TRF, with the front and rear gear gases swapped out for aluminium bulkheads. The rear bulkheads are even the same sort of shape as the TA04 rear gearbox. I like! 

If it's the same ball diff and one way, presumably things like the lightweight one-piece diff joints would work too?

Will look forward to the next steps 😃

As far as I know bases the TA04 chassis on the TRF414 chassis…from the race track to the consumers :D

There is a short summery about the history of the TA chassis family on blackholesun.fr:

Tamiya On-Road Chassis: TA Plattform

Do you mean the Tamiya 53480 TA04 Lightweight Diff Joint Set?
Two of them were installed when I bought this chassis. So currently they are spare parts ;)

What really impresses me is that there is no play in the suspension in drive direction.

This is not comparable to my TA02, TA03 or FF01 chassis...

The manual suggests a Dyna-Run Racing Stock Motor for this chassis. Last week I found a really cheap one, but the motor needs first a bit love before it finds it's right place.

Cool, I didn't know the Dyna stock was the suggested hop up motor for this chassis. I think I have one kicking about somewhere too. Might be nice for my silver 414M too. Can you get replacement decals for it?

And the way forward regarding my TRF garage which I want to restorate...

img_5306x2ctg.jpg

 

On the left side a TRF415MSX Marc Rheinard Edition...

img_5308akcvw.jpg

...and on the right side a TRF417V5

Since my last post ist almost two month ago and there are some changes in my garage.
The TRF415MSX is no longer member of this club :(

After a close inspection, it turned out that pre-owner had used a large amount of threadlocker to almost all the screws. Removing these without destroying something was immpossible. And since most of the aluminum parts also didn't look that great anymore and replacing them would have cost a small fortune, so I decided to sell the complete chassis.

In this case, I will now focus on the TRF417 V5.

Short introduction:

11e09217-a363-40fa-954e0c.jpeg
(Source: www.tamiya.com)

In Celebration of the 5th Championship!
The 7th biennial IFMAR ISTC World Championship took place in July 2012, with Tamiya driver Jilles Groskamp achieving an historic victory over a field containing the world's best. Not only was this an unprecedented third consecutive victory for the TRF (Tamiya Racing Factory) team, it also brought Tamiya's total IFMAR touring car title haul to five. Tamiya has now made this hi-tech championship-winning machine available to customers as the TRF417 V5 Premium Package Chassis Kit.
(Source: www.tamiya.com)
 

So I de-assembled the complete chassis, give the re-used parts a bath in the ultrasonic cleaner and re-ordered the bad or missing parts.

The cleaned re-used parts…

442c9117-4820-42db-97ieuq.jpeg

…and the ordered spare parts.

952ba931-3d67-4b84-9c7el2.jpeg

Let‘s start with the build…tomorrow ;)

Let's start with assembling the gear diff (rear):

img_5658grc3s.jpg

 

Filled with oil...

img_5659pze4f.jpg

...and the finished gear diff.

img_5660t4ibv.jpg


It goes on with attaching the rear and the motor bulkheads:

img_5665dpd08.jpg

img_5666spi6u.jpg

img_56674ydj0.jpg


Next step is attaching the gear diff and the short drive belt:

img_5674w0ert.jpg


The upper bulkheads...

img_5675kherc.jpg


...and ready assembled

img_56768kcxm.jpg

img_5677bbca2.jpg


Then we come to the spur gear and the long drive belt:

img_5679k3e4z.jpg

img_5682m9fni.jpg

img_5684ykd62.jpg

img_5685crdl8.jpg

 

That's it for now for the rear section, let's build the front (bulkheads):

img_56875neeh.jpg

img_5688nycnr.jpg


As the former TRF417 chassis, the TRF417v5 uses also a spool in the front.

img_569257i14.jpg

img_5693pbdxa.jpg


And the current status of the re-build:

Today we build the steering linkage and the front and rear suspension arms.

The steering parts...

img_5705k4fbo.jpg

...and ready for assembling with the chassis

img_57109zipw.jpg

img_5712uud3h.jpg

img_5716rqe8r.jpg


Now we install the upper deck with the guidance for the belt:

img_5735qdcbk.jpg

img_5736ihc0k.jpg

 

Then we continue with the rear suspension arms.

img_5754imclc.jpg

img_5758ymc55.jpg

Instead of the ball connector for the dampers, the pre-owner used ball nuts with set screws.
Maybe with the goal to change the damper without popping the damper everytime off the ball connector which can cause play over time.

Despite the use of the diff-baldes, the driveshafts were quite worn.
In this case I bought new ones...

img_5761uqi7r.jpg


Parts for the rear axles...

img_5762xhemw.jpg

img_5765ngera.jpg


The rear upper arms and the titanium coated suspension shafts.

img_57667ifhh.jpg

img_5768szija.jpg

img_5769fhfcc.jpg

 

After the rear suspension is done, we do the front supsension...

img_5773c5d70.jpg

img_5775chf43.jpg


...then front suspension arms...

img_5779wleof.jpg

img_57858vfz5.jpg

img_5787fpdcr.jpg


...and finally the front axles with upper arms and the suspension shafts.

img_57893viyl.jpg

img_5793ubew9.jpg


During the assembly I found it strange that the swing shafts had a lot of "play".

img_5795q9e54.jpg

After some research I found out that the previous owner installed the diff joints of the TRF418, where diff blades must also be used.

In this case I quickly installed the second pair of diffblades and finished the front suspension:

img_5801ljfa8.jpg

img_5796u1e6f.jpg

img_5798g1ef4.jpg

That's for today...

Awesome work @Sgt.Speirs and amazing cars!B) Don't know how I missed this thread so far.

So what body shells will go on these cars? It will they be displayed as chassis only?

@Kol__: They will be displayed as chassis only. But the TRF417v5, I want to run and for that I will use a Skyline R32 body.


Today we come to the dampers. When I bought this TRF417v5, it comes with standard TRF dampers:

img_5826t0erh.jpg


But for the TRF417v5 are provided aeration dampers. Please correct me, but I think these are unique for this TRF (onroad) chassis.

img_5831m0fi1.jpg


For me, it's the first time that I assemble this type of (aeration) dampers.

In the end cap, you have to drill a 2.5mm hole that there is a passage to the screw hole coming from the side. Via this hole, excess oil can escape during the assembly.

img_5830gfftd.jpg


The assembly itself is not very different to standard dampers.

img_5835ubca6.jpg


Everything to mount the rear dampers on the chassis...

img_5839sii4j.jpg

img_5840crdc4.jpg

img_5842z5i6n.jpg


Then almost the same parts for the front section

img_5844mmi06.jpg

img_5846fmiuv.jpg

img_58478pizp.jpg


The manual shows the chassis with a brushless system, but IMO there is currently no tamiya combo with a good price / performance ratio. And I want to remain brand loyal...

So I decided to use a Super Stock BZ with a Tamiya ESC, but it will be no ESC from the TBLE-series... But later more.

img_5848criwm.jpg


Also new for me...mounting the motor through a hole in the spur gear :D

img_5849r9ctb.jpg

img_5851jsd3o.jpg

img_58554qcng.jpg


That's all for today...and only 3 days until christmas. I have to hurry up that I can start with building the TB Evo 5 :D

Looks amazing mate! Those big bore aeration shocks are so cool, I'm tempted to fit a set to my TT02, assuming they would fit, but probably a bit OTT for that basic chassis.

@Kol__: I think these are/were the TRF Alu dampers and not the big bore variant. The big bore damper body looks much bigger in the diameter as my ones.

It's going on with mounting the servo.

img_5867gldtl.jpg

img_5868accnz.jpg

img_5870mue47.jpg


The installation of the ESC I have to skip due to it just came today.

So the body posts and the front bumper were then at the row.

img_58726qfkk.jpg

img_58733wio3.jpg


Regarding the wheels I decide to use the standard Tamiya wheel/tire set.

img_5877qjdbf.jpg

img_5878ssftb.jpg

img_5881m3ddh.jpg


And here we have the ESC for this project...a TEU-302BK.

img_5891k2d2c.jpg

img_5890m0cvu.jpg


With the length of the servo cable I wasn't satisfied, so I replaced it by a shorter one (and with also match the color of the ESC).

img_589955iuk.jpg


And that's the status of today.

img_5900bkiam.jpg


In the next days I will take some final pics and then is the sub project "TRF417v5" also done :)

There is a new member in my TRF garage...this time not an onroad vehicle.

With my transmission conversion for the King Cab chassis, I have my first experiance with the TRF201 chassis/transmission. So what seems closer than to have in the next step a look to the complete chassis.
So two weeks ago I got the chance to get one and was lucky enough to make the final bid for less then 200€.

So here we have the beauty:

ecb547fe-6d6c-44d9-bvadmp.jpeg

e92c24a0-253d-4be2-9aoi3m.jpeg

 

The complete package was „ready to run“. The following components were also included:

  • LRP Spin Pro sensored brushless ESC
  • LRP Vector K7 8.5T brushless motor
  • Savöx SC-1251MG low profile servo

And a radio (Carson Reflex Wheel Pro LCD with two receiver), a second set of wheels/tyres, some setting tools and some spare parts.

In the next weeks there will arrive some additional spare parts, some hopup parts and some other parts to complete the new look.

I don’t want to tease too much yet, but the new design will be not a typical TRF design, it will becomes a more vintage look.
