40 Year Old Porsche 935 Turbo TOY RC Car - Can I FIX it?
Вставка
- Опубліковано 23 січ 2025
- In this video I attempt to fix a car that was sent into a TV show, but didn't get chosen. Elliot from @TheRetroFuture@elliotcoll wanted to take a look at it and will do the bodywork, but he wanted me to look at the electronics. Can we get this much loved toy to work again all these years later? Let's find out.
Remember that this is just for entertainment and I am not an expert in these repairs. The processes in the video may not be the best way, the correct way or the safest way to fix these things. I do love fault finding and trying to fix broken things, so I hope that comes across in these videos.
Many thanks, Vince.
43:46 "people ain't going to sit through hours of me fixing a little toy car" - Turns out this people did! :) Great video xx
Cheers Kip 😎
What a Joy to watch! In this world devoid of Peace, these kinds of videos make us forget all that is happening outside the four walls of the self. Thank you. Keep posting.
"Devoid of peace?" My god, man, it's not that bad! Only a small minority of people continue to wreak havoc on others as they have done FOR GENERATIONS. Instead of speaking in generalities, point the finger at those responsible!
@@mitchd949 I am not talking of Geopolitics or Politics. I am talking about general life mate. Like normal livelihood things. I am not blaming anyone. I am just saying that world is devoid of Peace. I, as a man, seldom get time to explore these kind of things. Morning to evening Work, then fetch for family, then cooking, then sleeping strategically so that I can wake up early. No time to pursue the self. No time look at innerself. So many dreams have died like this
@@mitchd949 Btw, do they sell these kind of RC cars now? I never seen one.
@@mitchd949you can’t point fingers without getting into bother, and this isn’t the channel for politics 🤔
@@tsamgurkhan "General life" is devoid of peace? I'm afraid you are suffering some level of depression if you truly think this is the case. Enjoy what you have and quit dreaming about what you don't have. Life is largely toil. You have family - enjoy them! If you're cooking, do it well and enjoy your efforts! Morning to evening work is something pretty much every man around the world must do - so do it well and be the best at what you do! Seek some counsel if you truly feel like this - be it close friend, religious leader, psychiatrist, whatever.
Sometimes going that extra mile makes it worth it. You could hear the smile in your voice as you remembered playing with yours as a kid. So def worth going that extra bit.
You never cease to surprise in the amount of patience and care you put into all your fixes as well as your failures. Keep up the good work Vince I always loook forward to your next video weather it's the Rolls, some fix off e-bay or a veiwer project. take care matey.
Voice over Vince was wrong at the end, this was a super enjoyable video that's including its length
Another great fix. Love it when you bring old toys and electronics back from the toy graveyard. Best wishes from the USA.
I always say if its worth doing , its worth over doing . And this is a perfect example . Im glad you stuck with it and went the extra mile ... that little bit of extra work made a world of difference
“Won’t be a great video” in fact is a great video enjoyed Vince whatever the owner wants it restored for you did them proud with the work you put into it . Keep the videos coming interesting as you say on the steering how far remote control cars have come .
Vince like you say time using the car a lot with enjoyment, but time with wear and tear and winding down, exactly like us Humans as we get older. Vince great Video and great finding the problem and putting it some right for your Friend
Awesome video Vince, had the Jeep Renegade when I was a kid, brought back great memories.
Interesting steering design. I have never seen something like that either. But you put so much work in it and it worked out really, really good!
Wow. Herculean effort, Vince! How many could pull this off? This is why I love watching your videos.
Epic. Brilliant. As usual. You're the best, Vince.
A 3D printer would be great investment you can get small ones quite cheap now. Then you would be able to make these plastic parts that you keep coming across broken. Keep up the great work.
43:52 I sat through it all! Used to drive me nuts as a kid my toy RCs like this just stopped working, satisfying to know a lot why!
Never too long Vince.
Heat setting the gears on the shaft seems the way to do it to me. I would have tried hot air. Nice work on the fixes. Thanks for the video
Good job, Vince. I'm not really surprised that the TV show is more interested in cosmetic fixes. Judging by all the fake UA-cam restoration channels, that's what people are into these days. It's the TikTok idea of style over substance. For those in the audience, a flashy "before" and "after" shot will speak louder than showing a tiny crack in a plastic gear.
Keep doing things the MMV way, though. I don't want it any other way. I love to see how things work, and how they can be made to work after a breakdown.
Having just gotten into hobby grade RC myself, this was an excellent justification for getting a car with a brushless motor. I did go to brushless for my lest two RC's (for speed purposes) but now i see other reasons why brushless is preferrable.
If it's on TV, it's fake.
Oha.. a collab with Elliot - very nice!
49:38 - "I think we've done alright". Speak for yourself Vince - I think I was bleedin' brilliant. Best fix I've ever done actually.
Steering by braking is easier electronically since they only need two transistors to drive it; to drive a motor in both directions they need an H-bridge.
Thanks Skonk 💪
Could have had two motors like Vince originally thought, that would work the same. I like that idea, though you'd need to add gearing etc which is a pain. The "turn by braking" and dragging a wheel feels a bit crude, even if it's cleaver and cheap.
@@j.f.christ8421
The braking is actually not locking, but rather increasing the respective wheels drag..
@@KorAllRBare Ah right. that make a bit more sense. Was wondering if you'd wear a flat spot into the tyre if you went round & round for a while.
Hi Vince. You might want to replace the capacitor across the motor terminals. It prevents the arcing which burns out the brushes and commutators. It also reduces RF interference.
You always deliver Vince, I can't help but think you should invest in an enclosed 3D Printer ( so you can use nylon) as I think it could help you solve a lot of problems!
So glad you didn't join the toy hospital. Loving fix it videos and the repair shop I tried watching it only to find It was awful. Basically unwatchable with no charm at all. Keep up the good work, the diversity of fixes on your channel is a source of pure joy.
Is this a Car Tuning Channel now 😀Big cars, little cars, cars all the way! Nice fix Vince!
Hahaha, I struggle on them all BIG or SMALL!!!
Well done vince for all the work u put into getting this fixed .
Great job Vince. Loved watching the whole video.
You have to scratch the metal shaft really good before gluing a gear to it. I just fixed an old dilbert candy dispenser like this and where I scratched the metal shaft alot the super glue dried almost instantly as it got into place and its really permanent.
First remote control car I ever got was a Trans-Am with that controller. As soon as I saw it, dang...nostalgia. You mentioned the perhaps not necessary effort, but I'm sure glad you did what you did.
Hi Vince, can't tell you what an absolute tonic you are and maybe one day I'll explain that in more detail. However, the plastic gearing issues you frequently encounter could they be resolved with 3D printing new gears... your intelligent and capable but maybe that's not a viable route cost versus video returns but was just a thought and my main point on commenting today was more over to express my gratitude for helping me through some tough times. All the best to you and your family.
Thanks Darren, I appreciate your kind words and advice. I hope things are getting better for you 😎
This was beautiful to watch. Definitely would watched if it was 2 hours long.
Hi Vince, great video as always! And what a surgery you did to get this one working!!!! You really fixed the heart of this one! :-) But, the main reason I'm posting this comment is something that occurs in alot of your videos. You know, when something doesn't work out very well or an attempt fails, you mix that childish "Ha haaaaaa" thing into the audio (not sure if there's also some visuals included in that clip). It may seem something unimportant to some people, but for me, it really puts a smile on my face every single time. You see, my smartphone is full of those little clips playing when I receive all kinds of notifications (a bicycle bell for a new mail, a little clip out of an old Belgian detective series saying 'How are you? I'm fine, what about you?' when I get a new Whatsapp message, another clip out of that same show saying 'Let's see what's on this picture tape' when UA-cam anounces a new video ... ); it is just so typical for a blind person like me to have that kind of sound thingies everywhere. So, when the "Ha haaaaa" thing comes around once more when I'm watching your videos, it's just so funny! :-) By the way: is it one of your children doing that "Ha haaaaa"? :-)
Nice fix Vince there’s no end to your talents 😊😊
Hahaha, there certainly is many ends, but cheers Gary. I appreciate that 😎
@@Mymatevince I was being serious, I’m down your neck of the woods next month 😁
Vince, I always watch your videos right til the very end so I can learn from you (even though you tell people not to recreate what they've seen in the video) it's good information to keep in mind. Thanks for another great fix it video, I never had one of these remote control cars as a kid but I love these fix it videos whatever they are.
Mike In Newcastle.
Thanks Mike 😎
I had the black Taiyo pick up truck with top lights that you can turn on and off, it was the most enjoyable toy I had. Mind you I used to go through batteries like crazy.
That's interesting 😊
That's annoying 🤔
Always good to have catchphrases..
Started to rewatch and count these.
Seriously though you've teached me a lot. I knew nothing of electrical components... Now, through your videos, I have a very basic knowledge. Which is amazing for me...
Keep up the good work/videos.
Cheers Vince 👍🍻
Ask yourself "What is the past tense of the word 'catch'?"
Bet you don't say catched.
Yet you say "teached".
I love your work, Vince. I knew about your channel from Steve :)
You've got a new subscriber :)
I think the hole in the gears are made to exact measurements and if you put the gear in boiling water and the shaft in the freezer, the parts will lock up once they become the same temperature. The big boys do this with the big gear boxes in the D9 Cats :-)
I wonder if they did that in in the eighties in the Japanese factory. To me it seems a friction fit would be a much faster, cheaper and easier to assemble.
@@rogierius friction fit?
That steering mechanism is the most insane and unique thing that I ever saw, along with 4 speed synchronized manual transmission in Sucko (sorry if misspelled) Electro Real Mercedes (I think it's 230 model).
Enjoyed that one Vince. Thanks for sharing.
Such a great video! ❤
OK, not even watched the video yet. But here I go: battery connectors and small plastic gears. And when you use it the rest of the family Vince loose WiFi. Love your stuff NJLA
You should invest in a 3d printer and use abs to reprint those gears. It would take just a few minutes with high detail and they would work great.
Don't use ABS to reprint nylon gears - use nylon. :) It is a little bit harder to print, but the gears are very durable. ABS is not abrasion resistant.
Often you can get the 3d models for gears from sites like McMaster-Carr.
I have used petg and it seems to have worked. Easier to print than either abs or nylon....
@@greendragonmakerspace It will work in most cases and PETG is better than ABS in regards to abrasion resistance. Nylon remains best though. :)
@@TylerDurden-pk5km what about PLA?
@@goku445 Not ideal for gears, to brittle and not self lubricating.
Will run rough and wear down - at least if run often and fast.
Loved watching you fix this. Nice oine
It looks like you need to get some heat in those tyres for some grip Vince!!!
😂😅🤣
taio , dickie and all those brands , use 9v for recieving , all lower voltages are used to drive dc motors/and steering coils/motors (vary between models)
looking forward that you repair more of these because they are quiet valuable once repaired
Mr. Vince, I think you could have soldered a short piece of small brass tubing onto the end of the broken spring. That brass tubing with the solder in it would run for years more.
The toy has sentimental value because someone has owned and played with it. Restoring it to and 'as new' condition would take away its character. I hope Elliot doesn't respray it in Gameboy Grey with matching purple decals 😄
The braking solenoid design was novel. Maybe a 3D printer (from Margot) in your next stocking. You can use a nut-spinner etc to push-fit cogs onto shafts (better than the smash-it-with-pliers approach).
I have some consoles, I have seen you fix before, and I wish to send them to you, hopefully not too long into the future...
Very nice fix and look into how the steering works, that's unusual way to do it.
I've got wired controller version of this kind of Porsche in red colour, about 1/25 scale. I even have the original box for it.
It's my childhood toy from the 80's, but it doesn't work anymore. Plastic bits inside the controller are broken for both accelerator and steering, and also seems that wiring is broken as well between controller and the car.
If I inject power directly to the motors, they work, but from controller side, nothing works, no continuity between the controller and car.
Tried to make new plastic parts to replace broken ones inside the controller, but those broke as well. They are put into quite a stress by metal contact springs.
I just decided to leave it as is. Cosmetically it still looks pretty much like new, thanks to keeping it in the original box all these years :) I rarely kept any boxes, but for few toycars for some reason I did.
I’m so excited to my little car on the move. Nicky
Excellent, thanks for watching Nicky. It was working so smooth at the end. Fun little car! I think it would benefit from some donor battery terminals though 👍👍
I wonder if you dip the shaft in acetone before you put the gear on. The acetone will melt the inside of the gear and maybe glue it on.
Manufactures cool down the shaft and then the gear is put on. After the shaft get back to the normal Temp it fits tight
Fantastic work ethic with ingenuity and patience in equal measure. Pretty sure you didn't actually have to test it for QUITE that amount of time, alas 😉
Dear Mate Vince . Found this supercreative video once on how to deal with small plastic gears like that. Since im not allowed to post yt links i will just give you the name of the video. Its easier that you think. video Title is : Super Glue and Baking soda! Pour Glue on Baking soda and make gear wheel
oh i love those bultivibrator based controllers , capacitors are the key for scrambled movement but tuning it to correct frequency is a pain
walkie talkie reciever helps to troubleshoot the thing
i love how new toys have stearing working while not moving but the older ones only turn while driving :0
if you listen to the controller signal on the radio it is analog tone mudulation, one tone forward different tone backward and if you pulse width mudulate the ratio it will turn one side or the other while goung straight when ratio is 50:50 positive and negative
if i was fixing it with those chinese gears i would probably stack somedouble gears and cut off the bigger ones because they are the most likely to have hole diameter bigger than 2mm for that brass moving transfer shaft
I think those gears are injection moulded straight on to the shaft, thats why they don’t slip or have any play
If you need drill bits that are sub-sized, look for the ones made for PCBs. They are available in fractions of 0.1 mm. The shop I by them from in the US sells them individually.
I fixed my Radicon 1970s beetle that I've got off of eBay the other day, it has a similar steering mechanism. it basically locks the wheel on the left or right depends on the input
really interesting design!
You need a 3D Printer and then with practice you can print your own gears, great work on the videos
I enjoy the corrosion videos, somewhat satisfying 😂
Good Job Vince ;-)
My first thought about the turning at this point in the video is something about pressure applied from the weight releases some kind of saftey switch
I got a load of Tandy returns from the 80s -90s. When I worked 5here I bought their dump bins so there a few toys and rc cars. I am happy for them to go to something like retro toys etc. if in the Bristol area, they can collect the lot.
Loved Tandy back in the day. What a blast from the past. Did they get taken over by Maplins?
@@Project0-944 Naha .. they were a franchise from the USA Radio Shack and went bust. I believe some stores in the US have taken on the Radio Shack name as a loose group like SOAR stores in UK. I did enjoy working there as a Saturday lad but probably spent more than I earned … LOL
CA glue (cyanoacrylate, AKA superglue etc) sets by reacting with the moisture in the air. I think I've said this before, but storing opened tubes/bottles in a modern fridge where the air is dryer due to the dehumidifier will ensure they last many times longer; you should be able to pick up a cheap beer fridge for the purpose if M objects to using the kitchen one :) I've had tubes of CA in my fridge last for years with no problems
Slantnose porch IS 🔥
Haha love your vids, and this one especially, seeing as its RC, my favourite content 😄
Great job vince😅
Brilliant job! I did wonder if heating the bar (with no other gears on it) would help "bind" it to the bar? Just dont heat too long? End result is excellent though - it runs so smooth compared to how it was!
AND the steering works better than expected!!! I wonder if heat and also roughing up the bar a bit with some sandpaper would help melt the gear on and give a key to make it stay in place. Smooth plastic against smooth metal with all the forward and reverse action will surely make it slip over time if it is just friction fit. They DO appear to all be friction fit on these toys and apart from the cracking from age they DO work reliably so I don't understand how they don't slip. Cheers for watching Chris 😎
@@Mymatevince a lot of plastic gear box toys i had taken apart as a kid i distinctly remember the metal shafts were rough or had deep groves gouged in them sometimes with cross-hatch patterns (could possibly even use a file or pair of pliers just something really rough to scratch it up). same with everything else for gluing i suppose, just want to increase surface area, and in this instance, increase friction too. sorry to hear about the toy hospital not going your way and think they must've had a very difficult decision. both yourself and elliot are great in your own unique ways. fingers crossed something else comes your way!
@@darkstar_448 Thanks Darkstar, I'm going to rough them up from now on, and now you mention it I do remember seeing those cross hatch bits especially on toys where the metal axles meets the wheels 👍👍
A TOY FIX! Yasss! I love these!
Always love your videos, but this one especially as my brother had that exact same Porsche but in red
When I was a kid in the 80s our parents got us a cheap remote controlled car that was designed to only turn in one direction. So, the cheaper ones only turned in one direction.
I used to replace small broken cogs like that (like, broken in half) with-peace of rubber from the printer roller. It was the main motor cog on a banknote counters that had that problem. Friction to other cog was sufficient. Slippage was non-evident (everything was synchronized after that cog!)
The trick is that you have to drill a small hole in the rubber to fit a spindle, not just puncture it (as rubber will crack).
Yes seen that steering before as a child in the 80s had a Knight rider Kitt trans-am with that very steering. Seem so over complicated to a servo but Because it was not propositional i guess it kept the electronics of the time simple
nice fix. I guessed about 10 seconds before you regarding the brake steering lol. Have you tried the fireball yet?
Not yet Emma, I've been in a blue mat/car/editing tunnel for what feels like since Christmas, but at long last I have some videos finally coming together and awaiting release. So hopefully going forward a bit of normality can resume and the Fireball will be purchased 🥂
he is so exited droping stuff and all 😂
Hİ Vince, turning mechanism is not by motor but by electro magnets. I had the same car but a VW Gold in 80s. When you want to turn right magnet at right wheel powered and keeps the wheel and same for the opposite
4:20 i usually assume, the springy contact is neg. Solid contact is positive. Am i wrong?
Same here, these ones just seemed so wrong. If it wasn't for the sticker I wouldn't have had a clue how to insert the batteries👍
I had one of those as a kid but it was in the Rothmans colours. No idea what happened to it.
I wonder if they use acetone on the metal axle then push the gear on so it chemical welds itself on.
I think this was a mid way point between the ones who only turned left on reverse and the watch and pinion type. With single motor.
Nice repair Vince if you’re probably going to be fixing older gear boxes like this, a good investment would be a 3-D resin printer I don’t know if a regular 3-D printer would work. I would have to try on mine but I know a resin printer does more detail. Printing, possibly gears in the future.
Thanks Q 👍
have you ever tried 3d printing parts like the gears
Childhood dream, to fix a RC car.
The steering it achieved by induction braking a bit like a skid steer but in an electronic version.
Hallo Vince. This is a nice and interesting video as always. Carry on with this fixes. I every day look forward for a new video of yours. But there is one thing that is annoying for me as a german. The pronounciation of the brands name PORSCHE. As the most english and american native speaker you say PORSCH. Without the E at the end. But in fact you have to speak the E at the end. It is PORSCH-E. Its not only a brands name, it is a familis surename as well. So please speak the E. 😉
Greatings from Germany.
Thomas
Nice old Porsche I like Porsche cars
I do not have experience with this, so I apologize for my ignorance. If someone had a 3D printer, could they scan the cracked gear and 3D print a replacement? Would 3D printed material be strong enough to do that? I would think so but not sure. Enjoyed the video, Vince! *Edit: I think I should have looked at the comments prior. Looks like it could be done. :)
The reason I think they went with two electro magnets as brakes to steer is cost; a motor is several electromagnets on a spindle, surrounded by magnets, that's got to be more expensive to make than two simple coils.
Wow, I had that RC-controller too. For a totally different car tho'.
I think the reason it doesn't apply the turn-brake when it isn't moving is because it has to reverse it for forward/reverse? If you are moving forwards and want to turn right, you'd brake the right wheel. If you are moving backwards and want to turn right, you'd brake the left wheel. When you aren't applying throttle then, it wouldn't know which one is correct? I am also impressed by the cleverness of that mechanism! 😄
When I first of all read this on my phone I tried to work that out in my head, and in my head whether it was forwards or backwards right was right, but you are of course completely correct. It needs to brake on different wheels depending on whether travelling forwards or backwards. Makes more sense now, brilliant comment, thanks for taking the time to post it. A nice clever (but strange) work around for steering on an early RC car 👍👍👍
I had one but it used c cell batteries and went pretty fast!
Hi Vince and others. NICE Work, You're Hired! Fun even if i got lost in mechanics. 44:00 lol had already typed this ..
Curious. re: gears \ axle turning. One gear anchored or tight fit to hold in place on axle. [re: next idea] attached for specific job .... Excellent - I'm not only one wanting to know what grips gears to do job. PLUS, i see there's axle & hollow 'shaft' with gears tightly fitted.^^
21:12 Steering: motor[s] Left & Right. ["Brakes"] 1st, those tiny motors are cool; 2nd idea as Tuning^ Radio; Not 'braking'. If gear attached to wheel, free to slide in\out of motor, that ^'tunes' speed. lol silly, ok, but. Signal affects power, one side faster = turning
Have no idea what Gluing operation was. 24:58 "Q-bond", you "not have", but used? not baking soda'? ^^ glued to axle?
No worries, thinking out loud, hoping brain cell sparks. nope. hahaha i'm leaving thought - just for laughs.
*Thank You very much.*
"mechanics" - more like engineering. _what do i know_ : }
By braking a wheel to turn. It will wear out the front tyres quicker because the braked tyre will scrap across the ground.
Vince, you got me with that title because i thought you bought a Porsche
Sorry Jason, one full size car wreck in my life is more than I can currently cope with 😂 Once the RR is done though!!!!!
@@Mymatevince Vince in 3 years:welcome guys to the cheapest rocket in the UK,we are going try to rebuild this and go to the moon
I wonder if you could cast a new gear? Make a silicon mould and then use baking soda and super glue.
Another interesting video Vince. I’m wondering if freezing the shaft for the gearbox would shrink the metal enough to get a gear on? I know on a bigger scale it works but not sure about something this small.
Interesting, maybe it would. Hopefully someone will know how it was done in the factory, relying purely on friction against a super smooth metal shaft seems like it would lead to more failures, but yet these gears on various toys on the whole seem to be NOT glued????
Maybe a video on modifying the jeep with a new motor next?
Now I wonder how long it would have taken me to figure the front wheels out... Clearly longer than you :)
