Silver can budget rally build off

Just drove my modified TA02 in the snow. What a great car. Huge drifts and lots of control. I only managed 5 minutes before my hands went numb but it was great fun.

Has anyone ever considered the TT02 Type SR for Rally or is that really a road only version of the chassis? Tamico have a reasonable price at the moment.

Well, I have a TT-02 SR on the way from Tamico. However, the kit alone will stand me at minimum £175. That's with my estimate of vat and duty but without attributing a share of the £12 fee or the postage to it, on the shaky-even-for-Bernie basis that it just sort of hitched a lift with the other stuff I was buying anyway (it kind of did. Kind of). 

So, in the spirit of the budget rally build, I think really it's not playing the game. Perhaps it could be argued in - I have just secured a £5 poor condition body shell, receivers are well under a tenner and motor, wheels, tyres and ESC are parts bin, but even with this level of Bernienomics I'd still need the world's cheapest servo and to spend absolutely nothing on other mods. Better, I think, to use it as intended (straight up road/touring car) and look out for eBay bargains. Also, I read that the SR requires more invasive surgery to increase ride height than the stock TT-02, so I would be doing more damage to a nicer kit. Essentially yes I think it is more road specialist than the fundamentally versatile basic TT-02. 

So most likely if I'm going to take on this challenge it'd be with a second hand stock(ish) TT-02 or something like a TA-03, of which I note there are a few available, but I have no experience. Would any TA-03 do? I quite fancy the idea of a front motor mounted TA-03F but I'm not sure about buying a nearly 30 year old car. Is a chassis of this age really OK to use and abuse? Will the plastics have deteriorated too much for rally treatment?

Do it!!!! Give it a good home. Was a great build that one

In my hands for an RC car should probably not be considered "a good home"!

I don't think I'm going to do that, because (and I accept my logic here is pretty flawed, so flawed I can barely explain it) I feel like I want any car I have to be "mine". Like, built, modded, repurposed, refurbished, whatever, even if there isn't really any modification from stock, by me. I suspect I'd only either make Cy's car worse or keep it as it is.

I admire your economic honesty. Probably after though that the SR is more touring car than Rally car.

I think a TA03 is fine for rallying. The plastic on mine seem okay and it’s stoutly built. On the other hand, the TA02 is an easier conversation with better parts availability. I’m very happy with my recent TA02 mods and can’t wait to try it out somewhere off road. It was great in the snow yesterday.

Even as a touring car though, curious how you get on with your SR.

I will most definitely post up on here somewhere about it. I have done the sensible thing and bought an old trasher of a shell for a start, and good tyres, so it'll be all about the driving. I'm quite excited about it. I might build the M chassis first though, for postal racing. From zero I've suddenly gone all in on road.

My TT-02SR has arrived. No extra fees, so it has come in at £147.70 with postage pro-rated across the ordered items by value. So my number there would pass the scrutiny of even folk who might have even higher accounting standards then the good Bernie himself (should such people exist, which they may not, pillar of the financial compliance community that he is). 

So it could be a budget rally build. However, it probably won't be, sorry. At least not initially. It may however pave the way for another TT-02 of some sort. It's making the second hand prices I see rather hard to stomach.

With my package from Japan, got the invoice from Fed-Ex   a few days after it arrived.

Im not sure how the TB05 compares to the XV01 just yet as the weather hasn’t been up to much since I finished the XV01. The one trip the TB05 has done so far was fairly successful. It seemed to handle reasonably well, though I think more ground clearance and suspension travel would be good for the forest trails we took it on. Going to try a fairly gravely car park for its next outing when things aren’t so wet/freezing. The chassis is really, really, good at picking up debris and dirt so if I can I’d like to try and design/print some cover sections for it so it doesn’t need to be kept for nicer/dryer conditions. 

I can give a bit of an update on this now as I managed to get a little time today to get both cars out together. 
 

From the running we managed to do, on a mostly frozen mostly hard pack dirt car park, I’d now go as far as to say that the TB-05 is very different in character to the XV-01. Both handled very well and could happily corner and power slide with very little driver effort. But the TB-05 is definitely a much more aggressive car to drive compared to the smooth and compliant XV-01. It is possible some of this is down to the TB-05 running a set of soft rally block tyres,which may have been better suited to the conditions than the HPI clones on the XV-01, but I get the impression it’s a little more than this. 
 

I can also now confirm that the TB-05 is going to be a much higher maintenance machine that the XV-01. You can see the difference in how they look after both being run for the same amount of time today. Though, again, tyre choice may have something to do with this. Really have to get the 3D printer up and running to try and make a few bits to help.

Yuk! I wonder whether a lexan cover designed for eg the tt-02 might fit? If not, I have my eye on a sort of fabric mesh thing with an access zip for another buggy. Cheap as chips on aliexpress and probably adaptable to fit. 

I wouldn't be surprised if you found the tyre difference to be quite big. I think the soft rally blocks on my XV-01 are grippier on tarmac than my visually identical rally block clones were, although I ought to run them back to back to check this - I have changed some other things since.

That TB-05 looks just like my TA-03(Ra) after today's run!

It was sand yesterday, about half its body weight worth of sand.

I did pick up some mesh to try and make something like this but with the chassis being built the way it is there wasn’t anywhere good to fix the sides down. I’ve started modelling a few solid sections to try and cover up the main gaps on the sides and can then either go with mesh on the top or do another solid section there.

Been mulling over the idea of a TT-02 rolling chassis as a base for a budget rally build. Budget appears surprisingly comfortable, bearing in mind the PJ items could perhaps all be foregone (but also what will their postage be when they start offering surface again?), so what am I missing? Would it need different gearing options?

PJ never offered surface, only 1999 does that.

My mistake, not surface but I think PJ postage is about to get cheaper?

No rush for me. PJ prices with cheaper postage might enable a lot of in-budget tinkering on this. 

My thinking so far on a base TT-02 for rally is:

60mm YR shocks, partly because 65mm ones are suddenly £15 more (2 sets of 2 and slightly different shocks I think, rather than 1 set of 4 which are probably already totally satisfactory for this), but partly because I actually think mid level ride height on my XV-01 I like more than >20mm.

Probably do need front universals to keep the dog bones from falling out, but... 

I might do some learning with TT-02SR longer suspension arms before I commit to how to change a base TT-02.

If you did want something closer to 65 mm these LC Racing shocks may fit and are pretty nicely made, shame about the colour of course.

I never went near a basic TT for this challenge as they require too much to "put right", which will probably blow the budget.

(I based my calculations on new/unbuilt kit, not second hand where parts can be flipped)

What were the expensive shortcomings that put you off? I haven't gone all that deep in research. So I think I'm missing something.

My initial thinking was (after bearings, pinion, shocks obvs), that I mainly just need to cut and file a little for ride height, cover to keep the muck out, and add front universals. With then the option to add some parts to bring in camber and front toe adjustability (and actually the cost of this appears fairly modest). Are there other major shortcomings that are expensive to address? I figured with silver can the metal motor mounts, prop shaft etc wouldn't really be needed, and I could slow the stock diffs down with grease.

Big 3, the base kit has none of it. Take the TA-02 for example, has CVA. Then alum drive shaft, motor mount, rubbish steering. All these will probably blow the budget.

Edit: posted the last reply in haste. What I am meaning is I will probably consider the prop shaft and motor mount to be essential.

I haven't yet really experienced functionally enhancing steering with hop ups (except modding a little for Ackerman and bump steer with ball position at the uprights). Gotta learn about that.

What is it that's not liked about TT-02 steering? Slop and a bit of flex mostly? 

The budget (assuming LC shocks) could take YR aluminium steering and motor mount, but then nothing else. Or I could see if I can bodge sufficient steering improvements instead (tape and shims for slop seem in keeping with the budget build ethos, adjustable tie rods already in the budget). Then maybe I could blow the budget creating rear toe-in instead.

Gave it a bath. 😁 Everything is waterproofed. If you read further back, I had a non waterproof RX that took down the BEC on the ESC so now I apply a waterproof coating to the RX and the car can take a bath just fine.
