Sgt.Speirs‘ TRF garage (TRF414M & TRF417V5)

Recommended Posts

Hello all,

in this build thread I want to share the restoration and build of one of latest Tamiya on-road car in my collection:

The TRF414M

To jump to the next TRF models, click here: >> TRF415MSX and TRF417V5 section <<

 

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.

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).

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?

MCIracing has replacement decals for the motor…this is also my plan :)
