Just Superglue for mine.
Just cleaned the Lunchbox, which consisted of jumping off a couple of kerbs and shaking the loose bits off. 🙂
Looking slightly tattier, but works perfectly.
Oh, the grandaughter now wants a 'proper' car so she can race against the rest of us. Good grief.....
I think you'll do OK there, that Mario Kart wasn't shabby.
Done and ready to smash up so here’s a picture of it for posterity. Gone for a slightly stealthy look as I dont like the Mad Bull stripes.
Yay! Looks great.
Get it on some gravel, pull the trigger and guess where it is going to go!
Watch out for your receiver aerial wire. It is close to the pivot on the rear suspension and mine got nipped off at about half its length as a result. Doesn't seem to have harmed the range though.
You are right about the stripes. It looks like my duvet and curtain set from 1984.

Me and one of the yoofs had a blast on the local redgra / all-weather pitch. Already have more 3300mAh on order! Eyeing up the oil shocks too but having much fun on the pogo sticks it came with.
Put some of these on my Mad Bull today as it has been snapping the Pogo Sticks.
75 mm on the front, 90 mm on the back.
Initially it bounced like a bouncy thing, so I wound on about 5mm of pre-load all round and it is much better.
Looks pretty good too.
About to break.
Well thanks to Pete this thread has cost me £768.
Still its good fun 🙂
I'm at about £500 8-0
Harry_The_Spider - have you checked whether the shocks have any oil in them? Makes a massive difference to how they behave.
Err, about £850 down the rabbit hole so far.....ooops.
I really shouldn't have added it all up.
Ah well, finished the 2CV chassis last night, started looking at fixing the buggy and realised I need to order more bits.
Bum.

Not checked, but the description says that they are pre-filled and I'm not about to pull them apart to check. They are a vast improvement on the kit ones now that I've added some pre-load. Sharper turning in at low speeds and power slides at higher ones.
As long as they're performing that's all that matters!
Did a bit of work on the Lancia tonight: fitting the brushless motor. Easy to fit it to the motor mount and adjust the pinion alignment, had to trim the cooling cover a bit though to clear the connecting pins though. Actually means it'll get more airflow so possibly a good thing! Took a few goes to get the ESC into brushless mode though, thought I was switching it but I was actually just turning off reverse. Why do they make the orange and red LED's so hard to distinguish between?!? Oh and my soldering skills are very, very rusty. Could be the soldering iron as it struggles to hold heat so I'll blame that!
Got it running on the bench with the wheels off the ground, the auto brake was a bit vicious so turned that down before taking it out for a spin. First pull of the trigger and it took off like a scalded rat! Full-bore wheelspin, fully controlled but a lot more violently than the original motor. Top speed is only a little bit faster than the original but I can gear it higher now so that will solve that issue, should make launches a bit better too.
Got an issue though. After the first acceleration from switching it on and it comes to a halt it won't start up again unless you give it a nudge, whether that's forward or reverse. If I keep it rolling there's no issue, even going from reverse to forward or vice versa. Nipped it back in the flat thinking it was just an alignment issue but it's not. Even with the motor unmounted the shaft needs a little spin to get it going. It does move slightly, a degree or two but not enough to get it in motion. The motor has adjustable timing so had a play with that but it makes no difference (although advancing it does make it a decent amount faster). Could it be the ESC isn't happy getting it going? I chose this motor (Turnigy Trackstar 13.5T Sensored) as plenty of people on the RC forums have run it on the standard ESC (TBLE-02S) without issues. I know the stock one has some limitations so maybe worth getting a better one?
Haven't got round to fitting the shocks yet as I want to get it running and see how much of a difference they make back-to-back.
Traced the issue, a damaged sensor cable.
Was going into town this morning anyway so took the opportunity to nip into the local R/C shop, Antics in the arcades in the centre of Cardiff. They didn't have one as nearly everything they sell is sensor-less. Got chatting to them about stuff, as you do, and the subject turned to the differences between Tamiya and the RTR stuff. Had a look at a few different things and the difference is huge.
So to see if I like the other ones I left with this:

Fully waterproof, oil shocks all round and comes with everything bar some AA's for the controller. Even has a 2S lipo with it!
Should be fun round the local park, battery is already on charge.
I knew this would get addictive!
My mate has the brushed version of that. Good fun, not the most robust of cars but it's a hoot when it's running

Got one of those last week, on a grippy surface it full on motorboats on acceleration and in the long grass tore loads of it up with rooster tails of decapitated grass flying up 😀
Oh and don't mess about with it in the kitchen while your stood close it hurts 😉
Well it's rather rapid! Pretty easy to wheelie it and it lives to slide around on the power. Doesn't like lifting off mid corner though as it tends to want to roll, a reapplication of power sorts it out and then it drifts nicely. Much more fun on grass although the electronic brake is vicious so it tries to forward flip if you're not careful. Completely different drive compared to a Tamiya, a decent purchase I'd say. Needs a decent field to play in though and let it stretch it's legs.

I now have a few dougnut marks to clear off the laminate... 😁
What were you saying about this thread costing us lots of money? Ooopps...
Timmys That is a very nice kit, from memory they are a fantastic build and super nice buggy to run.
My brother bought one of them (avanti) of his mates when we were at school (early 90's). He never got it running - reasons i don't remember. It sat on his shelf for many years.
So go on:-
When is that kit from (does it say 2011 on the box)?
How much?
Well it's the 2011 re-release, but don't know when it was bought as stock would have probably been around for a while.
I paid £500, but that included the extra hop-up steering parts. I had been tracking prices on eBay for a while and they had been going for nearer £700, so jumped on this Buy It Now. It turned out there was a reason the price had dropped suddenly...
...they are doing a re-release of the 2011 re-release later in the yeah :doh!:
https://www.modelsport.co.uk/tamiya-avante-2011/rc-car-products/38927
But the price I paid still looks fair based on that UK price - and I have it in my hands now 🙂
oh my! that avante looks ace
That's lovely, but what is it with Tamiya and terribly lame slogans on the rear wing?

I've always assumed it's just an Engrish thing.
Not Engrish as they're a Japanese company so not bad translations, just some sort of weird fascination with english words that make them snappy - see all the weird Japanese import car names - Mazda Bongo and loads more here https://autowise.com/nissan-homy-super-long-and-12-other-weird-japanese-car-names/
As for that Avante up there - I just thought all these kits were just faster / slower / more detailed but (that's my Mad Bull up there) it's like Duplo vs Technic. That thing looks ace!!
However glad I bought the Mad Bull as the primary driver is 5 years old. Thank the lord amen for a huge redgra all weather pitch down the road...

I'm at the stage of judging when my almost 4 year old (well, me) can be justified in running a Mad Bull. When did they get the feel for it to make it worth it?
Tempted to stick a crawler motor in to begin with...
Can you use a paperclip through a small drilled hole in the controller throttle that stops it being pulled all the way back? Works well for Scalextric. Instant swap out when you want it to go faster.
Well, let my 3 year old had a go at the Unimog the other day who managed to roll it down a steep hill. Resulted in a snapped exhaust snorkel. Tried gluing it but glue doesn't seem to want to stick to the rubber / plastic like material. Tried super glue / contact adhesive which did not work at all. Now have araldite which just about hold it on, but not well enough to withstand another crash. Only choice is to buy a spare.
It seems like it is really difficult to get hold of any Tamiya spares at the moment, suppliers are quoting 2-3 months lead time.
Well, when I bought it, I couldn't decide if I wanted the 406:
or 425:
I ended up with a 425 and when I was searching, a 406 shell came up on ebay so I thought why not. It did come all the way from NI and my heart sunk when I saw the box:
Luckily turns out to be OK and now have my work cut out:
Not very good at doing shells but had some practice on a cheap Phatbody shell for my mini 8ight t and learnt a few lessons:
At the moment, quite tempted to sell the mini 8ight t. Although it is ridiculously fast and sunk a whole load of money to make it as reliable as it is now, it just doesn't have the same sense of occasion as when I take out a Tamiya (where I started about 25 years ago). Saw reluntantjumper's Lancia Delta and seriously considering buying one to replace the mini 8ight t.

I'm doing my best to avoid his Lancia, I'd love one of those 🙂
Anyway, had a quick Google to see if Tamiya had been inspired by the real thing for their naff rear wing slogans, and came across this link with some great photos from the 70s:

Enjoy!

It's difficult for me, I went into the local model shop the other day to get some paint for the new shell and they have one there. It's a bit more expensive than online but reasonable enough for me to not worry about the difference.
Trying to avoid the shop now as I know I will probably have bought it the next time I go in. I have been reading up on the chassis as well. Knowing me, by the time I finish building it, it will be brushless, on Lipo and an upgraded drivetrain / suspension to suit.
I’m at the stage of judging when my almost 4 year old (well, me) can be justified in running a Mad Bull. When did they get the feel for it to make it worth it?
Back in the day, I set my 4 year old brother up with some of my old kit, (and restricted the throttle.) We set up tracks in the back garden.
A 4 year olds small hand size makes control difficult with most transmitters. Some can be modified, e.g sticks shortened as I did. A neck strap is essential to avoid dropping the transmitter.
The other issue with 4 year olds and driving rc is they are too short. If you watch any rc race, the drivers stand on a tall rostrum because you need to be looking downwards on the car to judge its position. As your vision gets closer to parallel with the ground you lose perspective.
Smaller kids need boxes to stand on to compensate for their lack of height.
If there were no distractions and if he was heavily incentivised with "cow-sheep-pigs", (Percy Pig sweets) my 4 year old brother after a few weeks of practice could drive a lap or 2 around our garden circuit at slow speed in a stop start fashion without crashing.
This was better than my middle aged parents could manage.
Unfortunately my brother thought that holding full throttle as much as possible and crashing almost every corner was much more fun than driving in accordance with his ability.
He viewed me as a hypocrite, because he regularly saw me racing, knew I drove fast, knew I sometimes crashed, and knew i sometimes broke things. He would stamp his feet and accuse me of being a "meanie" for telling him to slow down.
It is very difficult to get young children to appreciate the benefits of slowing down or braking. Excessive damage to the car is a given.
7 or 8 would be a better age to start driving rc.
9 or 10 will allow them to build a Tamiya kit with minimal assistance, and is probably the ideal age to start.
Well the new sensor cables arrived in the post today so plugged it into the Lancia and hoped that would solve the running issue. Nope, still refuses to get going unless I give it a push first. Have double-checked the connections, re-soldered the wires, reset the ESC and started fresh with the setup and it's still the same. I'm thinking it's either a duff position sensor or a compatibility issue between the motor and the ESC although over on the MSUK forum there's people running the same setup with no issues so have asked over there if I'm missing a step.
Oh and seeing those Unimogs up there makes me want to buy a crawler too. No more purchases until I've got all 3 cars running again though!
Hmm.
Not an issue with the throttle EPA on the controller is it?
I think this is a 'thing' with brushless?
Can you reset the ESC to stock settings, make sure it's in brushless mode and give it another go?
Stuff like this makes me annoyed that my local shop has closed it's high street business and looks like it's going online only. I could pop in for advice (and usually ended up buying something new anyway).
Been through all of that twice now and it made no difference at all. Will try again when I have time and patience to spare. Someone on the MSUK forum said that it can be hit-and-miss whether the combo works or not so it may be a case of getting a new ESC. Will have to ponder on it as it's annoying that it runs fine when it gets going but won't move off from rest unless it's pushed!
Got fed up waiting for the new ESC for the Lancia to arrive so took the Bugsta out for a thrash round the local MX track hidden in some woods. So much fun sending it off all the little kickers! Only problem was I had to stop every minute or so and let the dust clear, no sodding wind to push it away. Still a totally different drive to the Tamiya stuff, much more of a hooligan. The downside is that the battery only lasts about 15 minutes, will have to order a spare or two.

The Tamiya Ship must have finally arrived!
New body shell and driver have turned up for my Mad Bull, but I changed my mind about what I was going to do with them back in June.
Ho-Hum. Good to have spares though eh?
Does seem to suddenly be a load of Tamiya stuff available now, good for some!
Took the Bugsta out again this afternoon and it ran fine for a bit but then made that horrible sound of a stripped gear. Investigations found a stripped spur gear:

Photo doesn't really show it that well but in the back of the chassis you can see the plastic remains of the tops of the teeth! Have ordered a metal set of spur and pinions for it as an upgrade.
Shouldn't need a metal spur. Your Stripped gear has almost certainly been caused by the mesh between the pinion and spur being set too loose. You can see from the photo that only the tips of the gear teeth have gone.
When meshed correctly there should only be a very small amount of backlash between the gears.
The other possibility would be if you have changed the pinion and tried combining 48 dp (imperial pitch) gears as used by most rc manufacturers, with the similar but not quite identical 0.6 moduli (metric pitch) gears as used by Tamiya and a few other Asian manufacturers..
The motor mount looks quite rigid si you can probably rule out chassis flex as a cause.
Both pinion and spur gear are the originals and a known weak spot on the Bugsta when run brushless. It was a matter of when not if! Plus I want it to be reliable so anything that breaks gets upgraded, it's a basher after all.
Well, unfortunately, when I opened the Unimog shell package, turn out there is a bit of damage:
Decided get it build up anyway. My thought being it is usable and a shame to put it in the bin. The Ebay seller is opening up a claim with Hermes, if I get a partial refund, great, if not, it's just another first world problem that doesn't really matter.
Doesn't look too bad once painted:
Really taking my time with this one. Now that I am back at work full time and the work starting to snow ball. As I predicted, when I went back to the local hobby shop to get some more paint, I did buy the Lancia Delta. Well, I was going to buy to TT-02 one but they just sold it the day before. They then made me an offer that I can't refuse on the XV-01 chassis one that they have in (very slightly cheaper than anywhere else online) and this is now in my house:
Not going to make a start till I finish the Unimog shell. Have the paint, already have the electrics ordered and have my mouse hovering over some essential hop-ups. Going at this rate, I don't think it will be running till Christmas. Still quite excited though.
Yay! Another Lancia to compare to. The XV01 chassis is meant to be a fair bit better than the TT02 for a rally car, wasn't available anywhere when I got mine. Now I've got the Bugsta for ragging around fields the Lancia will be turned into a tarmac spec car like I originally planned. Pity about the Unimog shell but then a Unimog without a dent or two is the same as a perfect Defender, doesn't look right!
New gears have turned up for the Bugsta, fitting them in a bit once I've watched a video or two on how to do it and set up the slipper clutch.
Retrieved my Mardave Cobra from my mums house a couple of weeks ago. So far i have painted and fitted a new shell, changed the radio gear and servo to digital and bought a 3300mah battery for it.
It is running an old Mtronics ESC and 13 turn Team Orion Havoc motor.
LittleMissHall had a shot of driving it yesterday and she did no too bad at her first shot.
Damn you Nicholas. For gods sake don’t post any pictures of that xv01. Been resisting one for months now, this might tip me over the edge.
Anyone wanting this Grasshopper with upgraded engine, 2 superior batteries, charger, digital controller, everything.
A few battle scars on the bodywork, but £100+post sees it as yours.
LittleMissHall had a shot of driving it yesterday and she did no too bad at her first shot.
I wish the 2 littleMissYius are as good as her. My 9 year old is OK driving the Unimog away but couldn't get the idea of it coming back towards her. My 7 year old just driven it straight into the stream and didn't seem too interested after that. I did have fun finding its way back up the bank under its own power though. My 3 year old son being too young just giving chase. All great fun.
I think I am another couple of weeks away from starting the XV01 build. Bought a cheap Hobbywing brushed ESC and plan to run the stock silver can on the 3S lipos that I have lying around. I heard it's the cheapest way to get speed out of it and apparently they last OK as long as I am sensible. Aftering reading up on them, I think the only hop ups for now will be the metal suspension mounts, front CVD and the uprated drive belt.
I might want to increase the suspension travel at a later date but I think that will do for now as it is apparently not straight forward to do.
Fitted the new spur gear to the Bugsta and also found out why it had stripped: the slipper clutch was set way too strong! Have just spent a solid 2hrs adjusting the whole drivetrain and it now just about gets the front wheels airbourne on full throttle standing starts without spinning the wheels excessively, albeit on wet tarmac. Once it's dry I'll see how it is and can adjust it from there, gets full drive without slip after a metre or so which is what is meant to be right according to the online guides. Nothing in the manual about setting it up so will have a session experimenting.
