Really nice work Randi!!! the RC truck came out MINT ! ! ! Thanks for sharing your wizardry with all of us! God Bless you Randi. Fred

[@RandiRain]

Thanks a bunch

[@craigleemehan]

Great job.

[@RoeVenturesLLC]

Nice

[@stevecann3394]

Great video, thanks ❤️😀

[@RandiRain]

Thank you.

[@keithfulkerson]

I had that same Sears version as a kid. It seemed bigger in the catalog, and I never had enough batteries for it after the initial Christmas playing. Such a trip to see it again.

[@adamkalb1412]

Impressive ❤

[@RandiRain]

Thanks

[@_Majoras]

i love your collection

[@RandiRain]

Thank you.

[@gshingles]

Nice job yet again. Rather than those 5V regulators, you should see if the switching 5V DC-DC regulator modules work with the radio stuff (they might be too noisy). They're far more efficient than the regulators that just dump the voltage difference as heat. As for the difference in current to the motor, the only thing I can think of is that maybe the current through the base isn't enough to fully turn on the transistor, or if it's a mosfet, the voltage isn't high enough on the gate (Vth) to turn on fully. Or, the motors might just behave differently (like you mention below you didn't clean the one in the transplant patient).

[@mancavehobbies6213]

Awesome my saterday afternoon is complete now with you.

[@RandiRain]

Thank you.. Glad I could fulfill your Saturday.

[@Traxxbandit]

the reason could be they have different pinon gears maybe different. Also I am the same guy asking about my r/c Nikko trans am Pepsi car. When you are ready i would send you the esc brushless motor and the trans miter for it. let me know when you would like me to send to you. I am in no hurry to have it done been a shelf queen for a long time. I would love to watch you convert it all to modern power and control. thanks

[@JessHull]

yeah you can just change the crystal on some of the old radios. You change the crystal in both the rx and tx. Some of the higher end toy remote comtrol cars etc had this feature. The only thing that I'm not certain on is if the radio was never intended to have swapable xtals there might be some capacitor tuning and or coils that's required. The radios that have the swappable xtals have a circuit that compensates for different xtals, so you can change them without issue.

[@RandiRain]

That's what I thought. There is a crystal, and I have bought one to change out, just haven't gotten around to it. I didn't think about the variable caps in there too. There is those too, I'm pretty sure.

[@whawaii]

@@RandiRain - It's not so much adjusting variable capacitors as it's a matter of retuning all the filter transformers to resonate at the new frequency. These are the ones that are a wire wrapped cylinder with a square bottom & an adjustment slug in the middle. However, because one of them works in the 49Mhz range & the other is in the 27MHz range, it's going to take quite a bit more than changing a crystal & some retuning. Some of the surrounding capacitors (& maybe even a few resistors) would need to get changed out also, in order to operate on this different frequency. I used to rework/retune my old 72MHz & 75MHz RC systems for maximum range. And I'd help my friend, a licensed HAM operator, convert his RC equipment onto the 6 meter band (50/53MHz). Normally it takes an oscilloscope & an RC spectrum analyzer to get the tuning correct. I'd recommend connecting up with a local ARRL Club (American Radio Relay League) in your area. I'm sure someone in it would love to work with you & maybe help you learn more about RF. Some of these members really get into building their own equipment & should be outfitted with all the proper calibration/tuning equipment. Try the "Cowtown Amateur Radio Club" at: www.cowtownarc.org

[@MidniteTease]

I remember even out-of-the-package-new Stompers; sometimes I would get one that was slower. You could even hear that the motor wasn't turning as fast. I never really looked into it, though. Knowing *more* about electrics now, but not much, I just assume that considering those small engines were kind of at the edge of technology then (sort of) and also cheap; that sometimes the spool of wire for the windings or something ran out early, or got replaced with some REALLY cheap stuff or the wrong gauge.

[@RandiRain]

I also forgot to clean that motor too...

[@crushedcan5378]

I would love to have the truck but in real life, like it would look just great! so when are we seeing the mutant car repaired?

[@RandiRain]

Be like the fall guy... The mutant car is done. I just haven't shot the footage of it working yet. Probably in a month.

[@Traxxbandit]

yes you can change the crystals. It is pretty easy. they are basically cb crystals. so you should be able top change them. just order the cryostat numbers.

[@RandiRain]

I did buy some, just haven't gotten around to change it.

[@alain99v6]

you could change crystal it would be probably easier on the receiver board because the crystal itself is part of a tuned circuit that usually include capcitors and coils dropping by almost half the transmitter frequency would be way out of tune and a lot of the tx RF power will be lost

[@RandiRain]

Hmmm... I see. I don't see a crystal on the receiving circuit, but there is one on the transmitter. That's why I figured changing that one.

[@alain99v6]

@@RandiRain if the 27 mhz and 49 mhz use the same transmitter pc board as the ones in this video you could swap the crystal PLUS the 2 tuning coils and maybe the capacitors

[@jeffreyhickman3871]

All retro RC vehicles will have 1️⃣ problem or another. For example, the once soft rubber tires 🛞 will get hard from age. Plastic gears can crack. Capacitors on the circuit board will become out of tolerance. Yes, that’s a long story. The motor bearings will need to be re-lubricated. Gears may need to be replaced, and greased, with hobby grade grease. Same goes for oil. Very nice retro style RC truck 🛻. Your friend, Jeff.

[@RandiRain]

You say that like I don't know any of that and haven't made hundreds of videos fixing those very things.

[@jeffreyhickman3871]

@@RandiRain I wasn’t meaning it offensively, even I’ve learned about things I never knew. I learned about electrolytic capacitors in 2016, in old radios 📻. I knew that capacitors or transistors can burn out, but I never knew that they went bad from age. Your friend, Jeff.

[@hydroxacte]

From the sound, the slower truck's motor is running at a lower RPM. (well, duh, it's slower) but what would restrict the peak rpm of a simple little motor? You might swap the motors to see if the slowness goes with the motor or stays with the controller/gear-train setup. If the latter, you have to figure out if there is binding in the gear train (unlikely) or else the controller is delivering less juice, and what you do about that I have no clue. If the slowness moves with the motor, then maybe poor brush contact?

[@RandiRain]

Yeah, I didn't even notice it until I was editing, but I forgot to clean that motor. It could be that.

[@sideburn]

Hmmm what chip is the motor controller? Could you try a power transistor as a test to rule that chip out? Or connect the motor directly to the battery to rule the motor itself out? Only thing I can think of off hand is the motor itself or that motor controller chip 🤔

[@RandiRain]

It's the L293D. While editing, I did notice that I never cleaned that motor either like I did with the other one. It could be that.

[@sideburn]

@@RandiRain yeah. I don’t know a whole lot about that chip and only a little bit of experience with H-Bridge drivers but I assume you are sending power directly from the battery to Vs (pin 8 I think) to supply the motor and not using any PWM to control the speed so yeah could just be that motor! If you get it sorted I’d love to hear what it was. Unsolved mysteries make me go bonkers 😆

[@sideburn]

@@RandiRain oh and yes you should be able to swap that crystal out and be good to go. I used to do that all the time with those old r/c controllers as a kid in the 80s.

[@generic53]

"Retro Rebirth: A DIY Odyssey of Electronics, Leaks, and Radio Control Triumph!" I LOVE when you talk dirty to me.

[@RandiRain]

You can thank ChatGPT for that.

Heard me for what I might look like being lazy but are you in Canada or the US? I keep ending up with remote control toys people throwing them out usually. Anywhere from the 1970s up. Part of it I deal with a lot of vintage toys. As an example I had a remote for the Radio Shack Red Claw tank held on to that remote nearly 20 years and about 6 months ago I got a red claw at a thrift store for $2 remote worked with the tank same frequency and everything and everything was fully functional and I sold the whole thing to a guy here in Nova Scotia. In a nutshell I've got a crap pile of mostly parts that are vintage and other stuff that's modern every so often people buy some of it here and there but I thought I'd see if you were in Canada mailing the stuff to the US is ridiculous. I thought I'd see if you were in Canada in case I've got some stuff that you can use or that you're looking for. Reason I thought I'd ask was that Trans Am I might actually have a remote for it not necessarily vintage but I might have one the right frequency and I've got a really old Radio Shack remote laying here on my desk for a Radio Shack Ferrari from the early '80s I don't have the battery cover but I'm pretty sure I think it's the same remote that goes to that Firebird I'm trying to find out what the frequency is in case it'll run your Firebird I've also got a whole bunch of new bright remotes from those remote control toys from Walmart probably 20 one of them might be the right frequency for that Firebird those new bright remotes are super basic like those old 1970s Sears remote vehiclesI've got a robot that I've been meaning to reach out to you to see if you've got the hand and your junk pile robots not worth me fixing and trying to track down the remote going to eventually clean it and put it on a shelf and I'm trying to find the hand where it's just going to be a decoration at some point pretty sure the electronics are screwed and it wasn't that long ago I could have got one in near mint condition with the box remote and everything for like a hundred bucks so the robots not really worth much other than it's a decoration just been looking for the hand short of trying to get one on eBay because to be brutally honest eBay they usually overcharge for just about everything.ive been dealing with stuff like vintage toys and video games for over 20 years and you don't want to know the stuff I bought on eBay for next to nothing despite what people actually charge on eBay. One of the tricks is a lot of what's on eBay people charge high prices but people don't actually buy at those prices lol. As an example I've got a Masters of the Universe vehicle that one or two pieces if you were to buy them you'd pay more than I paid for the whole vehicle and I still bought the vehicle in two or three pieces the vehicle completes like two or three hundred bucks and I'm into it for I think 60 bucks where I got it with the cockpit door missing and little bomb that goes on the bottom and I think I paid 20 bucks for that piece with the wings stupid Wings they want like 50 bucks each LOL cockpit cover I got for 5 or 10 bucks the bomb that goes on the bottom they want 50 and 100 bucks guy had one up opening bid for $9 and nobody bid on it so I ended up getting that for $9 I think shipping and everything I'm into it for 50 or 60 bucks it's still missing the two little tiny lasers that go on either side people try to charge 30 and 50 bucks each for those two lasers I literally have to go through a bunch of little toy pieces that are in a couple of Rubbermaid storage units in case I might already have them they're like an inch long. Otherwise I can get them 3D printed for like five bucks again they're a 1-in piece of gray plastic anybody wants to start paying $30 and 50 bucks for a piece of 1-in gray plastic they're idiots. Myself I mostly repair GI Joe vehicles and a few other toy lines and what people are charging for little tiny pieces would just make your head hurt. Little top of a tank the size of a Canadian $1 coin they're charging 30 and 40 bucks and I got one in a miscellaneous box a GI Joe parts that I paid 10 or 15 bucks for where it was like 50 or 60 parts and was listed on eBay just as miscellaneous GI Joe parts so like I said people off and overcharge. Been selling remote control vehicles to people for years that rebuild them like yourself every so often I run into somebody that buys a bunch of them. As an example I've got I think six Tyco terrain twisters a couple of flex packs that I don't think work anymore and a few Chargers and between them I might have one remote they take a really offset remote! Normally Tycho Vehicles go pretty quick but for some reason the terrain Twisters aren't very popular around here LOL usually when I get Tyco stuff it goes within a couple days of being listed especially if it still working I had and sold a few Radio Shack tanks a while back to a guy down here and I still got a remote for a Radio Shack tank that I'm hanging on to because I swear the tank is still somewhere here in the house I'm almost positive I never sold it back when I had an ebay account I know the remote goes with a tank that I had that I got at a yard sale but I might have sold the tank without the remote back when I had an ebay account. Haven't had an ebay account for selling in years since that postal strike they had here in Canada. Just figured I'd reach out on the off chance you're a Canadian in case I've got some stuff laying in a Rubbermaid container that goes with something you're working on or that you can use for parts for something you're working on where are the majority of what I've got is no name New Bright type stuff I've even got a bunch of helicopters and whatnot that nobody seems to want and I haven't got the first clue how the hell to work on stuff like helicopters

[@stevendunn264]

Measure the voltage to the two motors. Is it different?

[@RandiRain]

I haven't got around to it. It was a late discovery during editing. I did remember that I never cleaned the motor on this one like I did the other.
