+1 regarding the rear belt. When the rear belt goes, then that's it for the kit for me. I'm also having 2nd thoughts on the motor mounting. Unlike the 414m's, the TRF414 doesn't have a movable motor plate so the centering is off and the motor's resting on the lower plate. I can have the bulkhead machined and a plate installed but that kinda ruins the bulkhead.

The motor mounting for the 414X/414 is indeed slightly off center compared to 414M. I don't think it is worth it to machine the bulkhead to mimic the 414M. I think the main improvements that is needed is updating the drivetrain (gear diff and spool combo) as well as the suspension pieces. I believe someone has also updated the steering rack on it to a 418/419 as well but that is on their 414M.

Hello,

I am looking for a trf414 with the original tamiya aluminum setup wheels. If you have one I would like to hear from you.

Hello,

for a while now I have taken a interest in Tamiya's early TRF414 chassis, which I posted a question a while back about the development prototypes Tamiya made.

Now a member has kindly added a Japanese Article referring to 3 very early Tamiya prototypes called TRF404x which became the TRF414x

Here is the link from RCTECH with the article I'm referring to....

TRF 404x History ??

What was this Chassis based on ?

I assume when the request was placed to Tamiya HQ the Tamiya TA03 TRF was already released as a semi pro car.

It is unusual from the pictures provided, it looks like the first ever prototype used TA02 Shock Towers front and rear and it's alloy parts are anodized Blue.

I am very interested in their very first prototype of the TRF404x, my question is has anyone actually seen one of these ?

Does any one have any parts from this Chassis ?

Cheers

I saw those .pdf files that Mika had so generously uploaded as well and its a fascinating look at the early development of the 404X/414X/414 series from TRF.

The shock tower design has definitely changed from the initial 404X to 414X/414 release but I'm not sure if the 404X used TA02 bin shock towers. My reasoning is simply it would not bolt up to the bulkheads with pictures showing 4 bolts for the attachment of the shock tower.

From my own 414X I can see that only very limited parts were pulled from Tamiya's production bin at the time. Shocks are TA03 gold units and knuckles are TA03 aluminum pieces. The bell cranks are aluminum units that are shared with the TG10 car and the foam bumper is same as well. Not sure if the TG10 series came out first or the 414X/414 as my memory is hazy when it comes to Tamiya nitro cars.

Everything else was from scratch and brand new. Its also fascinating that the prototype w/ the pink foam bumper ran a chassis configuration entirely for stick pack. But the initial 404X was saddle and later iterations were certainly for saddle packs. Also it looks like they went with a symmetrical top deck initially but for the 414X release they adopted the asymmetrical deck from the 24 hrs race. For the 414 release they switched back to a symmetrical design.

Absolutely love the 414X and 414. To this day they are my favorite cars of all time.

attached a very small jpeg file that was googled and saved on my phone a while ago. it seems Tamiya kept the original 404X development prototypes. the left one is the "blue" anodized car and on the right it looks like its possibly David Jun's 404X with the left mounted servo. its hard to see the details on the middle chassis but i'm guessing from the transponder mount that this was the car used for the JMRCA.

so unlike the 411X and 211X where there were a handful of cars and parts that made it out to racers in the wild it looks like Tamiya kept all the 404X's that were produced as test mules.

Well done byteme909 !,

I have not seen that picture before, looks like Tamiya did keep the very first TRF404x "blue" prototype....

Due to the nature of a development prototype I bet that there is a lot of hand finished machined parts....yeah one off

Oh well....I thought it may be cool to build a replica for what every crazy reason...but I do have a TRF414x so its not so bad...

happy to share with fellow 414 owners and enthusiasts!

this project must have been a huge R&D money sink for them. it looks like they just went mental in figuring out the best suspension & chassis package. they must have sorted out the drivetrain early on as the various cars used the same bulkheads and diffs (aside from different finishes) from what can be seen in the pictures from Mika's magazine uploads. and they didn't take any chances with durability and went with full alloy pulleys etc.

yes we're very lucky to be owners of a car that only had 150 production units. did you ever run yours or is it a shelf queen?

I have always wanted a TRF since the days I started racing my M01 way back...but it was so hard to buy a TRF414x before the days of eBay... I ended up buying new a TA03F in the days when one would walk down to your local hobby shop and buy a RC car...

Can you guys please advise me and answer if you can:

- What's an excellent condition TRF-414M World's Edition(1,700 produced and limited) roller worth? What's a fair and good price for one (ie: I should pay no more than "$xxx.xx")??

- Would it be smart to buy one - as my Only 1 RC car, and also my returning to RC car (after being away from RC for a very long time, since the early '90s, I haven't had any RC since then).

- Are spare parts very difficult to find? If yes, it wouldn't be smart to buy then, no?

- Exactly which 414M spare-parts are very-difficult to find? I quickly read that the TA04 front and TRF415 rear belts fit. I'm sure the hardest part to find might be the lower/upper carbon decks. Any other very-hard-to-find spare-parts that I should be aware of??


I know the 414 is a classic and one of the best cars ever made...but I don't know too much about its' exact rare parts and other stuff I should be aware of. Ijdk which exact parts are the hard-to-find ones.


Thanks!

Here she is. My first new whip and return to RC, since the early ’90s. Very excited. I should have it by next week hopefully (seller still has to strip the electronics off of it; as we made a deal and I bought just the roller and spares).

Seller says it’s only been run twice on carpet track. Comes with a bunch of spares, wheels, bodies and original box and manual. Number 777 of 1,700. I’ll name her ‘Lucky’.

Just curious: Are 414M and 414M2 bulkheads cross-compatible??

Don't need them (yet). Just wanted to know and just in case, for any future event I might need spares.

I noticed the 414M2 bulkheads have rounded edges/corners (lighter weight I guess).


I think the two major concerns for hard-to-find parts (that are prone to breakage) are the chassis-decks and bulkheads, ya? Any other parts that are a concern?

With Fiber-Lyte luckily producing replacement carbon decks still (I think), the other main concern are replacement bulkheads.

Maybe some company will start producing them..given that the 414 is such a classic and still sought after.

If you use the old diff. You'll need lots of hard to find diff rings. An Evo4 and evo5 spool fits the front. Don't run mod unless you install a home made rear belt tensioner. Belt will strip. When you order spare shock towers from that company. Ask them to make them 3mm or 3.5mm thick. Highly recommend switching the suspension to the 419 suspension. And install DCJ's on the front. Also the one peice blocks from Tamiyas newer cars fit the 414. Buy them for more set up options. Good luck
