Default TB03 Chassis, Any Good?, What hopups?

I have a TA05. But unless its a perfect track, or indoors, the belts and gears get a hammering.

So im looking at a shaft drive. There are not a lot of reviews about the TB03 chassis yet.

Ill be putting a LRP AI Pro Reverse Brushless ESC and LRP Eraser 9.5 turn brushless motor.

What are the opinions on this chassis. Also what upgrades would I need to handle this brushless system.

I see the TT01 was popular in its day. But from reading the TB03 has already a few hopups out of the box.

Also does it come stock with metal shaft mounts. I read it did somewhere, but the photos and specs dont indicate this.

This would be for racing and drifting.

I hear the TB03 is basically a shaft drive version of the TA05. It also comes with the IFS front end with inboard shocks

So, if you like the TA05 and want a shaft drive I'd say go with the TB03. It's also pretty cheap for what it is I believe

Probably the best choice you can get, competitive racer and a good basher. It is fairly new, hence the lack of reviews.

Default RE: TB03 Chassis, Any Good?, What hopups?

Hi , I got a tb-03 3 month ago and so far I love it. Its my first R/C and I chose the tb over the TT because of the price (got it for 200 $can) and the upgrade part in the tb-03.

The tb-03 have a lot of hop-up and now they got the tb-03D out so we have more part like the spool.

The negative point so far is the steering , the Hole in the link between the steering are too large for the sleeve and that make it a little loose. The tb-03 really need the steering and link upgrade or a least a homemade fix .

The tb-02 have a weak ball diff screw and its break easy but the tb-03 got it fixed (I Broke the plastic frame when I was trying to tight it a little too much but the screw did not break)

OK thanks for the comments.

Group B Monster

Yes I read on another forum the steering was sloppy. But the thread did not advise how to fix it. Will look out for tamiya or 3rd party steering upgrades.

What metal parts come with the TB03 as standard.
I believe it has a metal motor mount. What about drive shaft mounts. Are they metal or plastic.

Will the standard gears handle a brushless system or do they need to be upgraded.

You say the TB03 is pretty cheap. Please explain. They seem to be quite a bit more than the TT01, TB02, or are you comparing to other makes of cars.

Cheers

Hi , the tb-03 do not have a lot of metal part .. tamiya want you to buy them as hop up . the only metal part that come with the kit are the drive shaft , the motor mount . but you can buy some more metal part. so drive shaft mount are plastic but you can buy them in allu if you want. about the standard gear I dont know cause I never use them , I went with aps gear and pinion ( the tb-03 allow many size)

I said its cheap because if you add the basic hop up of the tb-03 on a tt-01 the result will be 80$ + just for the hop up and yout tt-01 will not have all the tuning posibility of the tb-03 .
In my case the tt-01 were around 120 $can and the tb-03 198$ and half the part needed to make the tt-01 a not so bad car were out of stock

the way I fix my steering is a easy one , I remove the link and put some CA glue into the hole where the sleve go , and put the link on a paper , after 2 minute I lift it from the paper to remove the CA glue and that make a ca glue wall around the hole , lets it dry and try to fit the sleeve , repeat if you need more wall tightness. So far this trick hold for 2 month now, but im still buying the steering and carbon link im waiting on them to arrive at our lhs

Group B Monster,

Thanks for the info.

So if I go with the TB03, to improve it to race and handle a brushless system, I should buy the metal motor mounts, the steering and carbon link, and better gears. I will have a look at the ap gears you mentioned. Do you have a link with a part number. I havnt heard of those gears before.

Thanks for the feedback.

Cheers

Default RE: TB03 Chassis, Any Good?, What hopups?

the kit come with a metal motor mount and a 1 piece unit, with greater heat dissipation. you dont need to upgrade it. For the gear I dont know if they good or not with brushless ( I run brush motor) , i saw one guy recommend them over another forum , so I chose them. there some light weight pinion and I got them over there http://www.muchhobby.com/shopping/index.php?cPath=79

if you get a tb-03 I recommend you the carbon and steering, the 2 servo holder in allu (plastic strip easy) and the motor adaptor ((54054) they strip easy too), for the rest its all up to you, also dont tight the diff screw too much or like me you will have to get a allu diff join set for replace the plastic broken one.

OK Thanks.

Yeah it comes with a metal motor mount. I meant metal main shaft mount (to handle brushless) or is the metal shaft mount not required.
Is there anyone running a brushless TB03 can advise.

Ok will also look at "2 servo holder in allu (plastic strip easy) and the motor adaptor (54054)"

So extras are:

Steering and link upgrade
Servo Holder in Alum
Motor Adaptor (54054)
Alum Shaft mounts ???
Gears and Pinions ???

Cheers.

I just started accumlating a parts list for the heck of it to see where it would lead. But if as you say the belts on the TA05 are that much a pain outdoors, maybe my pipe dream ain't such a bad deal after all...

That car would cost a fortune with all those hopups.

Which ones are really required to handle a brushless system.

The TA05 is a good car even outdoors on a well prepared track. But not unswept parking lots with small stones.

Of course I may be a little jaded...so far I'd say I spent $1500 on my Tiger 1 and haven't seen it move under it's own power yet...lol...but it's getting closer...
The list was just everything I could possibly find (so far) that would be TCS legal...but as no one here in Cali seems to run indoors, the idea of a full boat shaft drive tub chassis "seems" reasonable...

Thanks Chatty.

Out of that very long list, What are REALLY required hopups for racing and to handle brushless and which are more for Bling.
Thats assuming your on a budget and cant buy them all.

Ah, shucks, who knows, I'm a noob at the track...my basic theory has always been that if an engineer somewhere was able to convince the bean counters somewhere that a hop-up was economically viable enough go to market, it must be "'necessary", right? All I did was make the list...you'll have to ask smarter people then me which ones give you bang for the buck... my bucks usually seem to go the way of the proverbial drunken sailor and then sit on the shelf after one or two runs...

OK Thanks.

The TB-03 is new so very few have it yet.

Ive asked on the TB02 thread believing they are similar chassis, but there are some big differences. EG engine mount.

However I would imagine many of the parts likely to break on the TB02 would be weak on the TB03.

I only really want to get whats required when I order the kit. Not the bling.

Default RE: TB03 Chassis, Any Good?, What hopups?

looking back at the list, yeah, most of it seems to be .01% gain over stock except the steering linkage which everyone seems to think is generally bad, and me personally I'm a fan of carbon reinforced or FRP parts, so for a basic build I'd focus on the steering, A-parts, K-parts, CF damper stays, the rocker arm bits, and the CRF chassis when it comes out...

but then again, I AM a noob...lol...listen to the smarter (more sober) voices out there...

cheers,

My thoughts now are, if it ain't broke, don't fix it. The only real upgrades I agree with there are the shocks and steering assembly. Other than that it's mostly bling.

Default RE: TB03 Chassis, Any Good?, What hopups?

I agree druss , if its not broken dont replace it . For the carbon reinforced part A part its the diff case K are the rear tower + motor cover .. I dont see the point to change them if its not broken. these carbon reinforced part are really at the bottom of the list for me.

the only hop up I have on mine so far are:

the DIff joint set ( I broke the plastic one by tightening the diff screw too much, and that why I think tamiya change the diff screw for a better one in the tb-03)

the carbon link + steering ( for fixing the lose in the steering)

the motor mount ( bottom one that slide, mine strip and my brother one too, so I recommend you this one for peace in mind)

the 2 servo holder ( the right one strip for me, If you get them there 2 option for the left one, the standard one and the one for the transpoder if you use it and want to put it there)

the rear propeller shaft ( I got that because im planing to put more power into my chassis and the allu shaft mount look better than plastic one)

The next part im gonna buy :

the spool

the main shaft (to handle more power)

the trf shock

I saw you still asking yourself wich one to get a tb-02 or tb-03

Lets me tell you what the tb-03 got and the tb-02 lack .

The tb-03 got a sloted engine mount that allow many spur and pinion and the mount is really well done with the vent at the bottom, changing the pinion take what 1 min max.

An improve diff screw

you can get a spool ( I saw on a forum that tb-02 owner have a hard way to find one)

MUCH better suspension arm ( tbevo05) reversible with many attach point ( tb-02 got 2 only, tb-03 got 4) to fine tune your car and ready to get a stabilizer bar

the diff cassing of the tb-02 look weak compared to a tb-03 they are really different, look at both pdf you will understand what im talking about , the tb-03 have 3 propeller shaft , and the tb-02 have only one shaft and they really different at the end, Im looking at that right now and by the design im pretty sure the tb-03 can hold more power.

tb-03 got a some nice C hub carrier

and you got some vent under the chassis

So far I really think the tb-03 is really supperior to a tb-02 by design.

Look at both pdf , and both part avaible and make your mind.

I Agree. Thats why im asking what do i really need for brushless.

These sound like a good idea,

Alum Racing Steering Set - TB03 #54095 or 3Racing 7075 Steering Racks For Tamiya TB-03
TB03 Aluminum Servo Stay - Left #54091
TB03 Aluminum Servo Stay - Right #54090
TB03 Aluminum Motor Adaptor #54054
HPI M2 x 25 Screws

These are possibles.

TB03 Aluminum Spur Gear Mnt #54094
Aluminum Diff Joints 54056
Heat Sink 54056
Gears and Pinions ???
Alum Shaft mounts ???
Gears and Pinions ???
Rear propeller shaft ???
The spool ???
The main shaft ???
TRF shock ???

Group B,

Thats good rundown of differences for those of us that dont have the TB02 or TB03 yet.

It sounds like for me the TB03 would be the better bet although its a bit pricier at the moment compared to the TB02.

the 2 servo holder ( the right one strip for me, If you get them there 2 option for the left one, the standard one and the one for the transpoder if you use it and want to put it there)

the rear propeller shaft ( I got that because im planing to put more power into my chassis and the allu shaft mount look better than plastic one)

The next part im gonna buy :

the spool

the main shaft (to handle more power)

the trf shock

I saw you still asking yourself wich one to get a tb-02 or tb-03

Lets me tell you what the tb-03 got and the tb-02 lack .

The tb-03 got a sloted engine mount that allow many spur and pinion and the mount is really well done with the vent at the bottom, changing the pinion take what 1 min max.

An improve diff screw

you can get a spool ( I saw on a forum that tb-02 owner have a hard way to find one)

MUCH better suspension arm ( tbevo05) reversible with many attach point ( tb-02 got 2 only, tb-03 got 4) to fine tune your car and ready to get a stabilizer bar

the diff cassing of the tb-02 look weak compared to a tb-03 they are really different, look at both pdf you will understand what im talking about , the tb-03 have 3 propeller shaft , and the tb-02 have only one shaft and they really different at the end, Im looking at that right now and by the design im pretty sure the tb-03 can hold more power.

tb-03 got a some nice C hub carrier

and you got some vent under the chassis

So far I really think the tb-03 is really supperior to a tb-02 by design.

Look at both pdf , and both part avaible and make your mind.


Group B,

It appears you are the only one on this forum with the new TB-03 Chassis.

Thanks for the rundown of differences.

Thats the sort of info im after.

I think its worth paying the extra for the TB-03 rather than going with the older (and cheaper) TB-02 looking at some of the improvements.

I may order it soon with a fews hopups. Is the 3Racing steering as good as the Tamiya.

Some of the hopups do not fit perfectly.
I had a non Tamiya motor mount in my TA-05. When I put in a LRP brushless recently, the gap between the motor mount screw and main spur gear was uncomfortably close.
I put in the kit motor mount and problem was solved. So the hopup was not really suited for a LRP brushless. Some of the hopups are slightly different fit from the original they are meant to replace. Its just something to be wary of.

Has anyone had problems with the plastic 'Drive Shaft' mounts. (on the TB-02 or TB-03). Would metal one be required for brushless or am I waisting my money.

Default RE: TB03 Chassis, Any Good?, What hopups?

Hi plane, I think you will not regret it , its a nice chassis and its competitive. About the steering .. I hear on another forum rc-tech i think , that the 3r steering was not very good.. so because I dont want to buy it twice .. I chose the tamiya one.. and corect me if im wrong but I thing Tamiya part > 3racing part.

About the close fit of spur , I dont think you will have a problem, to be sure i just check mine (a 64 picht 96 spur) and the motor mount (plastic stock one, I dont have my 54054 my lhs is pretty slow) you have a good gap you dont have to worry about I try many pinion some really tiny and the gap was OK the spur and the mount are not in line anyway.

Group B,

OK thanks. I will look at the Tamiya Steering.

Ive gone through and selected some of the parts I thought would be good. Its added up to as much as the car (160USD). So i think ill stick with the absolute required for now.

Cheers
