Supersabre driveshaft should be readily available - it's the same as the Boomerang, which was rereleased in 2017. The hotshot one might also fit, tho you may need different outdrives. Nice Madcap! You can also get some spares for that should you need them, as Astute parts also fit...
You still can't have it. (-:
Of course you're invited. 🙂
This Sunday, I think?
Let us know where and what time Harry.
I think I'll have two working cars, possibly three and maybe even four.
New car!😁

Is that cake?
Just finished a bit of a session sorting out the Lancia as it has taken a beating recently!
First task was to hoover out all the crap that had collected in the chassis and stick the ESC and receiver back down. They both had come loose during a skate park bash, that 3M tape isn't unstickable!
With that done it was time to sort out the body wobble at the rear. Thought about using some alloy braces but that costs money so dug out some old craft wire and cross-braced the mounts:

The top wire is just to replace using two clips to locate the shell as they were rubbing through the paint.
Next job was to make something to stop the gravel and dirt flinging off the front wheels and collecting around the steering arms, stopping them moving. Seen a few people online putting foam in the traps but thought I'd try a different tactic: internal mudguards:

Hard to see as I used some thin clear plastic sheet but it should stop the vast majority of the dirt flinging off the front wheels from entering the steering arm area. Did the same to the rear too:

Won't be as effective due to having to leave space to change the battery but should stop some dirt flinging in.
Talking of the battery, it rattles while in rough ground so I decided to pad out the chassis and the retaining arm with some purple foam sheet I had lying around:

Rather fetching I think!
Too late now to take it for a test spin so that will have to wait.
Got some oil damped shocks on the way too so that should help the handling. Then it's decision time on the motor. The stock 520 is fine but a bit slow so considering options. Do I just fit a Sport Tuned one and maybe up the pinion size or go for something brushless? Don't want to touch lipo batteries as I'm not happy with the fire risk if they're stored or charged incorrectly. Thoughts?
And yes, I am aware the table is filthy, a lot of dust, gravel and leaves came out of the thing as I took it apart!
Well the mods work really well. Body doesn't wobble and no more grit getting stuck in the steering arms!

Trouble is I have killed the motor. It was fine but then stated to slow down like the battery was running low then as it started to cut out on full throttle it jammed up. Thought it might be a stone stuck against the prop shaft but couldn't see anything obvious. Got it home and removed the motor to find it jammed, ended up pulling out this:

The motor now runs but very lumpily, either it was going to die anyway or I overheated it doing dougnuts and the plastic bits compromising cooling. Will cut the plastic back a bit and buy a new motor.
Question is do I go for another standard 540 at £17, a Sport Tuned Tamiya at £28 or something else? Anyone have any recommendations?
3pm Sunday afternoon, weather permitting, for our Razz in The Park?
Philips Park Whitefield. Meet in the car park then head off down the hill?
Sounds good. 🙂
Car park over the motorway bridge?
@reluctantjumper , I’d go for a Sport Tuned. Not sure where you’re looking at prices but you can pick them up on eBay for £20. I’ve a Torque tuned which is nice but not too fast. They can be had for £12 ish. Both work with standard Tamiya ESC. Other cheap low turn motors available, but you’d need a different ESC.
I went brushless in my Racing Fighter but it couldn’t handle it so I swapped back. Thinking of maybe changing to Sport Tuned but not sure how much of a difference it would be.
The prices for a Sport Tuned are from from sellers I trust on eBay and Amazon, plenty of places that will take my cash and then put on back order though for less. I want to get it up and running quickly so don't mind spending a few quid more to get one from a reputable seller who has one.
I've got the Tamiya TBLE-02 ESC so can fit most sensored brushless motors that are between 10.5 and 16.5T. It limits me to 25T or more for brushed. The chassis can easily handle a lot more power, especially once I've go some damped shocks on there, so just looking to not waste money putting a brushed motor on there only to jump up to brushless quickly afterwards. I wouldn't think of brushless for your Racing Fighter or any other 2WD car as that would be a lot of power to control through them (but fun while trying!). From watching a few videos on the differences while mulling it over I think a sensored brushless would be the way to go as they seem to have good control at lower speeds plus a good top end. Plenty to think about so if anyone else has experience of something it would be appreciated.
I can see me making this Lancia into a should-have-been Group B power machine...
Philips Park Whitefield. Meet in the car park then head off down the hill?
I know precisely one landmark in Whitefield and it's the Metrolink car park round the corner from Morrisons. Is it anywhere near there?
Google suggests Phillips Park Prestwich, is that the same thing? Where's the car park of which you speak?
It's too far for me to travel from Berks. Please post some pics.
TBH the tamiya motors are decent quality but nothing special, all the "tuned" stuff really just denotes the winds.
Happy memories of different windings/gauges of wire on slot car motors from over 40 years ago. Seem to recall Mura motors were good in those days. Raced on a 6 lane 150 foot wooden routed track at what was Reeds Paper Mills model engineering club.
After reading some of this thread it makes me want to get my little maverick ion working again after water messed up the electrics. The obvious thing to do would just get another cheap ready to run set but that seems wastefull as I already bought a new flysky gt2 transmitter with reciever and the car is basically quite new. Could someone who knows about rc cars perhaps talk me through what new parts to get to make it go again? What should I buy to make it all new motor and esc to run on 2 or 3s lipo?
For example would this
fit in without access to special tools and knowledge and would I also need to buy some new motor output cog? Would the original servo plug in to the flysky reciever or would it need replacing too?
I think I have a spare motor. Just standard mind but will get you going.
If it suits, PM me your address and I'll send it off to you.👌
I realise this is a n00b question, and I could probably find the answer with a bit of digging on tamiyaclub or some other Googling, but if my ESC is overheating when powering a brushed motor, is that likely to be because the pinion is too small - or too big?
(this is on the Mad Bull mongrel with, AFAIK, an unknown upgraded motor)
I'm confused because I'm guessing the ESC is overheating because a high current is passing through it, but I don't know whether the motor spinning up faster (with a small pinion i.e. a lower gear) would draw more current, or the motor having to work harder with a larger pinion and higher gear would draw more current. As a relative newbie to RC electronics I'd appreciate any advice you have.
FWIW I'm running the transmitter with the settings at 75% max power, which seems enough to keep the thing just about controllable - it will roll when turning hard at higher settings, but that may be because the shocks are pants. The main problem at the moment is that we can't run it continuously for more than about 4 minutes at a time because the ESC shuts down. Of course, maybe I just need a cooling fan...
Google suggests Phillips Park Prestwich, is that the same thing? Where’s the car park of which you speak?
Park is in Prestwich, south of the motorway. Entrance is in Whitefield, north of the motorway.
Google Sedgley Park Rugby Club (M45 7DZ) and carry on for a further 100m. The park gates will be right in front of you. Follow the road over the bridge. The carpark is on the right as you go up the hill.
Car park over the motorway bridge?
Yis.
I'll bring two cars, a spare battery and a hairy 12 year old.
@Pierre what ESC are you using? If it’s the standard Tamiya (TBE 02?) then its only rated down to 23T motors. Could be your updated motor is lower than that which could cause problems.
Bigger pinion may help but not by much.
@Merak - thanks for the offer but I've got the Lunchbox to play with for the time being so not in a major rush. Have been recommended a sensored brushless motor from HobbyKing via one of the Tamiya forums so waiting for that to arrive, should be here early next week.
@clubby It's that one, yes. Looks like it's time to look into either a new ESC or find out what the difference in turn counts means for motors. Which means being tempted by brushless, which means potentially putting too much power into a car that was never really built for it, which means breaking lots of stuff, which means being tempted to buy a whole new car, or maybe a couple...
I see what's happening here. 😉
Sounds good Andy, will be there.
Lunchbox and the Crawler. 🙂
Cougs, might be able to give you a lift if not meeting up with the daughter and grandkids - will drop you a line, just waiting to hear back from them.
That's very kind of you, but I think we're going to kill two birds with one stone as my better half's sister is out that way so we won't be coming directly home.
No worries mate.
Looks like we'll be meeting up with the family too.
I don't suppose you have a power kite you could bring, by any chance?
🤣
I've a cupboard full of the buggers.
Cheers HTS for the directions, I think I know where I'm going. Whereabouts in the park though? It looks kinda... not small.
Meet in in the carpark. We'll walk down together.
You mean I have to be... on time? Ye gods man.
If I wasn't on call I would have been up for this, only got a crawler "at the moment" 😉
Just told my OH, she asked what time, I told her and she replied "well... you'll probably be up by then."
Cheers for that guys, it was a giggle.
It took me to walk through the front door back home to suddenly realise, I could've brought my car and borrowed a battery...
Wasn't it? 🙂
Lovely to see everyone and nothing broke (too badly).
I think we'll be doing it again.
Good fun.....
Yeah, it was a hoot.
Cars cleaned and damage assessed. Nothing too major. Broken shock on the Mad Bull (again) but I've got better ones in the post.
We'll definitely do it again!
I've still got my Thunder Tiger 1/10 nitro R/C car under my bed. The only problem with it was finding a car park big enough.
Gotta say, I don't envy you having to clean those cars, it was minging underfoot. Are the buggers waterproofed these days too?
Any pictures?
I didn't think to take any, sorry. Something else I kicked myself for when I got home.
Though in my defence I was fighting with Aspie brain "argh strange new people!" and mostly trying to pretend to be something approaching normal.
Not waterproof, I think we were just lucky!
It was a trifle moist. 🙂
Not cleaned mine yet, carried on building the new one when we got home.
It'll brush off tomorrow....
A spot on afternoon, thanks all.
Cheers for the pictures. Shame I live too far away glad you had a good time.
Looks like fun was definitely had judging by the state of the cars!
To counter you lot having fun I've had some goodies arrive for the Lancia:

Now just got to figure out how A/B/C corresponds to the blue/orange/yellow wires, find my soldering iron, clean the chassis up and get it all installed. I've read that some people use Bring Your Own as a way of remembering A=blue B=yellow and C=orange, does that sounds right?
Finally getting around to building a Mad Bull and wondered whether there's anything I should be thread locking (Loctite 2400 Medium Strength is what I have). Instructions say no, but I expect there's some metal-metal fittings here that could use it e.g. the grub screw holding the gear onto the motor shaft, and the screws that hold the motor through the gear box casing.
Also what about this tyre gluing - what glue, what method? It's the standard 540 brushed motor so if it doesn't need it then I'm fine with that.
Glued the tyres on my Mad Bull as I've had them roll off the rim. I used Rocket Hot.
I haven't Loctited the wheel nuts on, but they do work loose over time so I nip them up before a "razz". Gearbox and motor screws have been fine. I wouldn't glue them anyway as you need to get in there to grease every so often.
