Tamiya TRF503 announced with picture

[caneye]

Traction rolling ???in what situation?upload your setup sheet.

hello Sir ... it is an indoor carpet track.

(I'd bought the car used and it was last ran on an outdoor track prior to me owning it.)
I've since rebuilt the diff and shocks.
- Diff 7K Fr & Rr
- Shock oil 400 Fr & 350
- reduced droop on all shocks
- Springs - Looking for super stiff springs. Ended up using AE's springs from a fellow racer (ASC91333: 12mm Front Spring (Orange/4.05lbs)). I believe this is a lot stiffer than TRF's stiffest front big bore springs.
Still searching for stiff rear springs.

I'm getting incremental improvements in the set-up .. still room for tweaks. :)

[SiR_Dave]

Is anyone working on a lower carbon fiber deck for the 503:cry:... really would like to see one... think I might have tweaked mine after getting hit mid air with a 8th scale Truggy:(

[D-StyleNZL]

Well round 2 with my 503.
(Least i have spares now!)

Ive notice that the chassis has alot of flex with the rear top deck removed. Even just with the belts at "normal tension" there is alot of pulling the deck up around the rear bulkheads. Even with the the rear top defk install you can see flex. Ive gone and double up on both top decks (as Aftermarket sellers dont seem to like responding to emails)
Just a quick shake down run so far only so see what it drives like on race day.
Also i changed the rear sway bar links to that of the TRF418 kit.

[SiR_Dave]

Yeah the chassis seems to be a little on the thin side... that's why I hope a carbon one comes out soon similar to the 511 with the updated chassis.. but with the shape of the 503.... 2.5mm would be perfect 3mm if some milling to it was done:D

Excellent quality work. Respond fast to emails. They may need a new chassis plate being a new car, to measure up. They will also do custom work if you can send measurements.

Maybe the 503 needs new top decks similar to updates made to the 502X?

IMO modern cars are being designed for modern high grip tracks. Thus why not stiffen the chassis up and make it rigid for these high grip tracks? Then fine tune the suspension? 4wds don't need to be as forgiving as 2wds due to the higher grip generation of 4 driven wheels.

I have asked Frederik if he can come up with a shorty pack conversion for the 502X, similar to Yokomo, B44.3 and HB 413. Should keep it competitive for a while longer! Why not do the same for 503?

[D-StyleNZL]

Chassis go in swings and round-a-bouts with Flex. Use to be you had to have a stiff as hell chassis, now its all the rage to have flex, then there be a slow change back to stiff chassis as soft chassis need to be replaced more. (its the same with motorsports)

Funny that you mention this...:) the new B44.3 layout looks like they moved the motor mount further forward like the 502x... and I have asked about a short chassis for the 502x as well before... but I have e-mailed fiber lite to see what they can come up with for the 503 and 502... I have no issues sending them stuff if they can turn it around quickly:thumbsup:

[Chris]

2.5mm top decks can be pre ordered now.

Almost out of stock!

[Holeshot]

Thought I'd put a couple of pictures of my 503 on here, well chuffed with the build, & awesome paint by Tel at Telsshells!

:drool: Looks fast just sitting there. Nice paint job to.

[SiR_Dave]

Almost out of stock!

So whens the Chassis going to be finished up for the 503 Chris:drool:

I have a few sets on the way from Japan right now... should be able to let you guys know in a week or so how they work out :thumbsup:

[D-StyleNZL]

I can maybe see why you may use these new shafts on the front to stop the "Chatter" vibrations at full lock. Thou using the WO series of shafts i havnt notice any issues from full lock chatter at all.

One other thing, ive doubled up on the kit upper decks (glued together) and havnt had anything bad come out of it.
flogged out my Alloy diff out drives after first meeting (the Trf417 ones)
Expensive exercise! Lol.

[MaxBaker]

I'm super interested in the 503 and I'm not one for following crowds so I want to give it a try over the more conventional b44 I see at my club :p

Anything I should know about it ?! Will only be used on astro. Which body shell fits without too much hassle ?!

Fell in love with it, looks wise, soon as I saw it. Are the shocks decent ?!

Cheers :)

[Holeshot]

Has anyone heard of someone using a shorty setup with one?

[taomo]

Hi,

I have some questions about the TRF503 guys:

1-According to EFRA size rules, what wheels do you use with the rear hex wheel hub (manual part BF14)?
2-And what wheels do you use with the front standard hex and the option 0.5 thicker hex #54406?
3-Last question, about the 54131 Front Upright and his lousy tiny ball bearing, is there any mod to fit the #51272 front upright with his big ball bearings using the same TRF503 WO Assembly Universal Shaft?


Best regards

1-I use the Tamiya wheels without hex (still the cheapest wheels on the market)
2-Tamiya wheels
3-What's the problem with the thin bearing?

[DG5]

With the hex you can use all B44 wheels (proline / JC / Asso) :thumbsup:

[taomo]

With the hex you can use all B44 wheels (proline / JC / Asso) :thumbsup:

Nop, with the original 503 hex you can not use B44 rear wheels because it exeeds the EFRA limits. For the front wheels with the 0.5 thicker hex #54406 the asso wheels are ok.

Chris, I use the Tamiya pin pink wheels in the TRF502 and it works fine in dirt but for the TRF503 running in astro and 5.5T motor, the tamiya ones became cheese and the pin broke the wheels (the astro is too agressive for this system).

The problem with the small bearing is that it is not as precise and robust than the big one. I noticed more vibrations with the tiny bearings in fast corners for example.

Best regards

[DG5]

i use proline rear wheel for B44/B4/RB6 and don't have any problem with the box :confused:

[Origineelreclamebord]

i use proline rear wheel for B44/B4/RB6 and don't have any problem with the box :confused:

Are you by any chance running tires with a shallow/no side wall extending beyond the rim (such as Schumacher MiniSpike)? Many clay tires, and some carpet tires (like the Schumacher MiniPin) widen the car quite a bit...

[suparajicon]

could anyone please tell me where to buy a front bumper for this car?

[DG5]

yes, for the moment i only use shum minispike because i only run on astro but this weekend i'll try shum minipin and proline pin point for my first race on carpet with the 503 !

but Lee Martin use proline wheel on the 503 proto so i think it should be work with most of tyre with the right setting

[Robbhp]

Does anyone have any low grip setups ?

[SiR_Dave]

Does anyone have any low grip setups ?

What type of surface..? Carpet, Astro or Clay?:eh?:

[Robbhp]

Guess that would help lol it's a mix of carpet and polished floors .

[D-StyleNZL]

Any update on how these new double CV shafts are going?

[SiR_Dave]

Any update on how these new double CV shafts are going?

Been running them just in the front of my TRF 511 and 503 for the past 3 weeks... pretty much a lot less chatter when turning .. and it almost feels as if the buggy now has more on power steering with them on the same set up:confused::)

[taomo]

Hi,

last sunday I broke a rear swing shaft. I think the problem was that the diff joint is too soft. Did you noticed that? Any solution?
Motor is a LRP X20 6,5T running in astro turf.


Best regards.

[Roel]

How are your slipper settings?

Looks like they are way too tight, the other outdrive on that diff is in need of replacement aswell.

Otherwise the driveshaft pin will lock into the worn out hole in the outdrive and lock your suspension is place as it can't slide in or out.

Little tight, I don't think this is the problem but who knows... I replaced the full diff by a new one and run today 6 LiPos perfectly.

[trowta]

Hello TRF's I really hope someone can help me out I am chasing the drive belt set for this car and no one seems to have any in stock can anyone help me out???

[Roel]

Not the cheapest shop but ussualy as most tamiya parts in stock.

http://www.modellbau-seidel.de/index.php?firma=Tamiya&best=6244030

[trowta]

Awesome, if I could only read Dutch .... Lol

[Origineelreclamebord]

With Google Translate you should be able to get there quite easily. Or, just send them an English email stating what you need but you can't read German and I'm sure they'll be happy to help out :)

[Roel]

It is indeed German.

But there used to be a button that changed the site into English, well most of the site anyway, but that seems to have been removed.

But indeed just send an e-mail to mail@modellbau-seidel.de and tell them what you need.

[trowta]

well that was an epic fail.. I contacted modellbau-seidel as advised and they have some in stock but will not post internationally to Australia and suggested to try the Asian stores... man all I want is some new belts!!!!

[trowta]

And so the build begins:woot:

Sir Dave
Can I please buy a belt set off you, I am guessing you have a few left...lol

[olefiloux]

Hi Guys!
I would like to ask to the Tam' boys if the gap between 511 and 503 is really noticeable?
Does this car gave more than the previous one? Just curious about updating my 511 for the indoor season...

best regards.

[SiR_Dave]

Sir Dave
Can I please buy a belt set off you, I am guessing you have a few left...lol

I only have 2 sets left... sold all of the rest ... Tamiya Japan is currently out of stock and will not have any until late December...:cry: Tamiya USA might have a few sets still left in stock.. but they are way overpriced!!!:bored: Hit me up if you can't find a set.. might be bale to help you out:D

[Origineelreclamebord]

If the belts are so hard to find through Tamiya, why not try to find the right belt through an industrial hardware supplier? :eh?: Most of the information should be on the belt, and with some measurements you'll be able to find a belt that works - perhaps such a store may even be able to help you out if you bring along the belt. I'll admit it's not the easiest road, but it's worth doing that instead of being completely dependent on Tamiya to supply what is a standardized, non-RC component :)

[Fredrik Emilsson]

I have 503 drive belts I can spare.

How many do you need? 2 sets?

[trowta]

yes please Fredrik that would be great!!! you have all my details and I will pay you with paypal

regards

Tod Trower

[trowta]

thanks Sir Dave Fredrik will hook me up.. also what is the part number for those allow servo mounts you have??

[MHeadling]

So is there a direct bolt on clamping 12mm front and rear wheel hex for the 511/503??

[patez]

Cool lookin setup. Not too much spare space for the battery.

[taomo]

Does anybody know if Tamiya will make a rear wheel compatible with the hex included in the kit?

best regards

[MHeadling]

Does anyone know the dimensions of the screw that goes in the 12mm clamping rear hex's on the 503??

[Roel]

Does anyone know the dimensions of the screw that goes in the 12mm clamping rear hex's on the 503??

It's a 1.6 X 4 mm screw, can't find a number but there is a part number for a bag of 10.

I have a picture of one sitting on top of the TRF503..... But it's obviously to short... Now it will fit but you will see the batteries sticking out from back of the body a little.. Should be able to post the picture up later today so you can see what I mean:)

Hi, I got it made from a specialist mate of mine, we are looking to release them in the new year along with top decks, shock towers etc, drop me a pm in the new year if you would like one and we'll see what we can do;)

[MHeadling]

Car looks great pugs :thumbsup:

I'll be interested in some 503 towers for my 511

[pugs]

Thanks mate:) I am sure the trf511 mounting holes on the tower are the same, it would just move the shock position holes using the trf503 towers on the trf511, I will check this for you;)

[trowta]

Great will do!!

Anybody knows the sizes of the ball bearings included in the #42283 Double Cardan Joint Shaft Front?
Anybody knows if exist a hardest version of the original #51472 diff joint?


Best regards

[SiR_Dave]

The bearing size is 5x10x3..
Now as for the diff joints you can use some sets from the 417 they seem to hold up pretty well... But you will need to buy two sets to make one complete set due to the different length on them... Don't have the part # off hand but I can post it up later ;)

I'm using it. No big differences but it is true that minimizes rotation vibration and car runs smoother. I have the rear ones but I didn't tried yet.

[DarkHawk]

If anyone needs any belts there are 5 pairs on ebay hk seller I think

[MHeadling]

Thanks Taomo for the feedback, think I'll just stick with the standard driveshafts

If your interested PM me

[xfactor]

Guys I have a 503 on the way.

Just want to know, are the front hexs the same as the 501, 502 and 511.

Also can you use rear pin wheels as I have a few new tamiya rear wheels. By not fitting the hex and using a spacer with a wheel pin.


Cheers all.

just to wet the appetite I have a custom made carbon fibre chassis made from 2.5 mm carbon fibre plate that I am testing, should make this car even better

One of the chaps at our club has a carbon fibre chassis TRF503 and double thickness top chassis parts and it handles brilliantly.

Fibrelyte have been making the carbon TRF503 chassis for a little while now, if you need any carbon TRF503 parts for it just ask them, they do them all and in different thickness's if you want them.

[SiR_Dave]

Been using a carbon chassis as well on my TRF503 for a few months as well and it's is definitely more predictable now vice the alloy chassis..:)

is that with the alloy std chassis or the carbon fibre?

[SiR_Dave]

Carbon Chassis... the modified set up has a lot of steering ..also Use either Clay Chainlinks or Proline electrons ... if you want to cut back on a little bit of steering uses a AKA pinstripe up front:)

Could somebody tell me what make and model these front hexes are and also where I might purchase them from. I'm looking to add 12mm hexes on the front of my 511 and wanted to keen a similar track width. Thanks

[SiR_Dave]

The 12mm front hexes are made by either RC Square or Active hobby and they are for any Tamiya Drift Chassis.... These can be purchased in Japan or in Hong Kong.

Is there a grab screw on this hex's ?

[SiR_Dave]

No grub screw... the fit on similar to the stock front Tamiya hex..:D

[ridgeracer]

I Use the 4mm thick 12mm hexes for Tamiya touring cars.
Just dremel or file the thin lip, takes about one min and you have 12mm clamping front hexes :)

[guinness]

Any new parts out there that will give more protection to the diff's?

[SiR_Dave]

What type of protection..? Belt or internal to the diff??:confused:

Tried that a while back and I had issues with the wheel nut not holding to well... might have been the nut I was using though:blush::eh?:

I know. there is less thread left than with your solution.
I use the Hobbyking serrated nuts, and no dnf`s yet

[guinness]

I mean covering some parts of the belts and diff's

:thumbsup: You got the last set...... Tamiya is also making a 12mm front hex soon so we should be able to get our hands on them in a month or so:woot:

Rcmart just email me saying that they canceled the order because they realize that STR154DB are out of stock.
Any alternative hex from rcmart?

Sorry to hear that. Front or rear? Upper or lower part? Due to impact/crash?
Send me PM and maybe i can send replacement part.

Yes, sir! Not enough time for playing, but i keep trying. :-)

Well please don't stop making cool stuff... for us :D

[guinness]

Guys can u help me understand why of this noise when breaking ?? Belts? Diff gears? Suggestions please https://goo.gl/photos/sAr9CqmoRH199qZG7

[MHeadling]

That's belt skip, have you got the rollers touching the belts on the centre pulley??

Can you show us where you have the eccentric diff cams positioned??

[guinness]

Rollers are like 0.5 away from belts ...
Diff cams position is with the dot perfectly on top at the rear and one slot forward in the front .

[MHeadling]

Ok, get the rollers running against the belt, not too tight but just enough clearance so it turns the bearing

Maybe try the front belt a notch tighter and give it a try, maybe take your brake down to 75% or put back the EPA a touch on the tx

I ran my 511 with fairly loose belts on carpet and not had belt skip

[The Doktor]

You have the front cam one notch looser than the manual advises. I found that if its in the position the manual states it can slip under heavy breaking at the end of a straight. So the position you have it, its deffo gonna slip.
I have it one notch tighter and its perfect.
Check page 23 of the manual.

[SiR_Dave]

Yep... you can run the rear belt looser than the front I have found out from making a mistake before:eh?::D

[GRIFF55]

Might also be worth checking the pulleys for any dirt in them

[MHeadling]

Does anyone know the part number for the Proline phantom 503 body ??

[SiR_Dave]

There isn't a specific Phantom body for the 503... you have to use the one for the B44.2:).. fit's on the 503 perfect... ( so does pretty much every other b44.2 body ;) )

[MHeadling]

Thanks for the info Dave :thumbsup:

Any tips for this 503 car on high grip carpet guys? Just made a few changes from last weeks terrible showing where i really suffered massive grip roll.

Front, yellow roll bar/600wt oil/Yatabe purple springs, links and shock positions as per kit. 2mm droop limiter.

Rear, blue roll bar/450wt oil/Yatabe orange springs, links and shock positions as per kit. 2mm droop limiter.

Running a carbon chassis and 2.5mm top decks, 6.5 Fleta motor, 4wd yellow staggers, venom rears.

Car felt fast and smooth, but cornering, albeit softer than the above change, was awful, so much grip.

Opinions for a noob 4wd TRF runner? Maybe i go out on the above, and ponder laying the shocks down?

Bests.....lee

TRF cars is too soft for high grip tracks.
Tamiya cars need harder all plastics... (2wd is same).

And tire preparation is big part of racing on high traction carpet. Cuting pins, glueing walls...

[ralphee]

Yet my 211 is amazing on high grip? OK buddy, thanks for the helpful info!

Lee

[akime]

My 211 is terrible on high grip.

[ralphee]

Then your set up is way off, mine is epic, traction to spare, aggressive, and jumps sweetly, im faster than my YZ2, a car that didnt suit me at all!

Lee

[spenner]

What sort of carpet are you running on ??

Ran my car at the first round of the Silverstone winter series, car was awesome!!

I have a feeling the carbon chassis is not helping at all, can't fault the car on any surface..

[akime]

ralphee:

This is all about your competition level...
TRF211 cannot be competetive to low riders or cheaters cars, if traction is really high.

No doubt.

Its that grey Primafelt i think? Car was silly fast, just excessive roll, and subsequent traction roll!
My Bmax4 could suffer the same when grip came up!
Ive heard others running the carbon chassis with improvement!
Ill try this revised front set up this Friday and see how she fares!

As for the 211, no, it wont beat a YZ2 or XB2 at higher level racing, but im happy at my level where the car is very competitive Akime, you are obviously racing at a much higher level than I, against more talented drivers too, in any case, i love the 211 :)

Lee

Lee

[akime]

i love 211 too :wub

[ralphee]

Post your set up in the thread on the 211 Akime, ill post what im running, never know may help?

Lee

[SiR_Dave]

Lee ... You might want to think sbout a piston change on the 503.... Possibly a 1.5x2 front smd 1.6x2 rear..:confused::)

[ralphee]

With some great help from Dave Bristol and Mark Headling, i finally got my 503 working on high grip carpet.
Car was initially very unstable, with so much front traction, and very little rear.
So back to the drawing board, and we came up with this set up.
Its still not perfect, still some slight front inside wheel lift on corner entry, but a stiffer front ARB and adding some droop may help this.
One huge improvement was using a shorter rear link, really helped stop the rear of the car rolling in an excessive manner and going to 20K diff oil in the front, was originally 10K at either end.
I did this meeting on front slicks, that were made from Yellow minipins, first run on additive, which was very good, but i think if you went this route, id apply every run as it was starting to push a lot by the later rounds.
Next time out ill try some tweaks, and do some runs on 4wd staggers, but overall the car was very stable, and very quick.

Just to note, i used the outer most hole on the rear arm, and, im running the Fibrelyte carbon chassis and 2.5mm decks.

Thanks to Dave and Mark, and a few other nice fellas, I now have something to start with on high grip.

Been tinkering for an age trying to get this right on high grip carpet. Getting very close to a set up i like now. Try it out by all means.
