Looks like the lower wishbones can pivot fairly low. That was my first thought. Front motor layout looks great, if suspension has enough travel (or can be replaced by standard TC or XV01 suspension), it could be decent rally car. Thing that I dont like about this chassis are integrated differential gearcases... Stripped thread means whole chassis disassembly (interesting how Tamiya used drop-in nuts in most parts, with exception of gearboxes) instead of swaping gearcase. Also custom chassis (for long wheelbase F1 for example) is impossible 2 Share this post Link to post Share on other sites

As is it seems to offer NO protection for the internal components from debris. Was actually thinking that it looks as if debris would be able to fall out of the chassis rather than accumulate in it? The drive train is sealed and the sides are open, (I'd pop some foam under the steering arms to stop them jamming) so maybe just a skid tray rather than a full undertray? I'd not be bothered if underneath got a bit battered though! Looking forward to the first run report 😁 1 Share this post Link to post Share on other sites

Yes, ample openings to pass through debris, and you'd probably be just fine. I'm in a Desert... Our Sand is high in Silica. Personally, I'd like to avoid the risk if I could. Regardless of how small. If I was just going for a Desert Bash.... I'd grab a TT-02 FIRST. Otherwise, I'm really curious about how hard WOULD it be, to make my own Lexan Undertray. In fact I may start with one for my TT-02 modified "Rally Special". Those are KNOWN for collecting pebbles in the Steering! 😉 1 Share this post Link to post Share on other sites
wtcc5 4688 Posted August 24, 2020 I don‘t know if it is necessary to go through this trouble. There are dust cover nets for bashers that work very good for different vehicles and are attached easily by velcro. 1 Share this post Link to post Share on other sites

I just like to look for excuses to create things. 😉 The Dust Covers are pretty effective. They just don't always LOOK so great... To ME. What I'm considering is something similar to what the Avante, Schumacher, and an option on old Kyosho Mods and Ultimas (aftermarket on the Kyosho) A made to fit, full Undercarriage Tray. Not only prevents debris from being forced up by spinning Wheels, but also add a layer of scuff protection for the lower Chassis - especially if you've got CF or Aluminium Plate under it!! I promise, this isn't a sales pitch!! Just tossing up an idea.💡 IF I'm able to get my FF-03 - you can BET I'll be making one!!! They don't weigh very much, and don't get HEAVIER when it gets WET! 😊 Share this post Link to post Share on other sites

Carmine A 2046 Posted August 24, 2020 Didn't mean to be part of the "Threadjacking Conspiracy"!!! 😜😄😂 Looking underneath - I can now see clearly the need for some underbelly protection. Thanks so much for sharing this in such detail. I would still want to try to get the FF-03 FIRST. But this Beauty is definitely on the List! 😎💯👍👍 Share this post Link to post Share on other sites

Superluminal 3729 Posted August 24, 2020 If you get hold of a wheel and waggle it about a bit is there any more play in the steering and suspension joints than you would expect on a traditional suspension set up? Share this post Link to post Share on other sites

ChrisRx718 4464 Posted August 24, 2020 Suspension is very.... TT01/2! Eek. Are the pivot balls the same size? Tamiya made an upgrade low-friction pivot ball set for the TT02, I wonder if that is compatible? (#54559) Is there provision for a little LED in the rear housing above the diffuser? It looks like there should be (not that Tamiya makes a single red LED kit...yet...nor are you going to be able to place an LED control unit anywhere!) It's cool because it's new, but I do feel a little disappointed. It's more expensive than a TB05 Pro but offers no advantage and surely a higher CoG? I say all this but give it 4 months and it's Christmas time I'll probably end up buying one... 1 Share this post Link to post Share on other sites

Nicadraus 6130 Posted August 24, 2020 I'm surprised to see a box stock build from you. Not a single hop up parts was added. Is it really you wtcc/Kevin? Seriously, nice documented build. Like I mentioned before, I can't wait what you'll transform this into (soon?). 2 Share this post Link to post Share on other sites

No. The suspension is super stiff. No bending at all (remember the F201 in comparison 😂). Slop is good, just a tiny bit more than a good race tc. The steering has too much slop for my liking. The steering bridge is stiff as a wet towel. It needs definitely the aluminum upgrade 💴 1 Share this post Link to post Share on other sites

I say all this but give it 4 months and it's Christmas time I'll probably end up buying one... The suspension is flawless like it is. Indeed there is a provision for a taillight there. I for myself was very disappointed with the chassis design of the TB-05. The price is in comparison to TB-05 pro just a tad more expensive. But I don’t think Tamiya made the TC series to compete against chassis. It is just to have more freedom for upcoming body sets. The TB is more of a racer chassis. The topic with the cog is not that easy. Having weight so far inboard also reduces tilt. So maybe both chassis are even here. 1 Share this post Link to post Share on other sites

But at first I want to drive it stock. So the body will come at the end of the week. And then I start with silly upgrades.

lowspot 299 Posted August 27, 2020 Sehr coole Foto Story !!! Thanks for sharing the detailed pictures - clearly better than any Youtube Video and it makes me want to have one.

ruebiracer 1024 Posted August 27, 2020 Yesterday evening I had the opportunity to inspect the TC01 of my friend, who finished it this week. Kevin did really give all the infos on it! I´t´s mch more than I expected, and probably a scale chassis, that fits in betwenn the Tamiya TA / TRF And TB chassis range. Although I´m no Formula E fan in any way, the assembled complete look is outstanding and I can´t find any comparisons on the market. And everything is way more solid and worthy as on a TT01/02. For 229€ at Seidel in Germany at the moment, you get real bang for the buck. By the way, the pivot balls are not the same as TT01/02 and made of solid aluminum. Also, you get body pins/ bumper mount and everything already within the kit to use std. touring car bodies or the Tamiya LMP body. Go on Kevin, body work is a lot of work, my friend refused to do another for the next days. 3 Share this post Link to post Share on other sites
Carmine A 2046 Posted August 27, 2020 @ruebiracer Couldn't agree more!! He did a magnificent job of presenting this Build! 👍👍👍👍👍 He easily sold this Chassis to several People who might have been on the fence. And yes, considering how it's designed, it's a bargain!! 2 Share this post Link to post Share on other sites
