RC V8 Truck Electronics & Mods Installation!

[@paultinwell5557]

The RFI is caused by a high current spike in the high voltage cables each time the ignition system generates a spark. You may be able to help the problem by using inductive type ignition cables (typically a fibre core wound with a spiral of wire) or resistors in the spark plug caps (a few kOhms will be enough). A smaller spark gap at the spark plug electrodes will help too. Otherwise, consider trying to shield the entire ignition system... not an easy problem to deal with, so good luck!

[@Altprophet]

Shield the secondary ign wires!

[@Fix_It_Again_Tony]

I was thinking resistors as well. This is what was done with full size vehicles to limit radio interference. I think they are typically built into spark plugs. Not sure if the primary of the ignition coil has a capacitor, but that could also help. Copper shield sleeve is also available to fit on the outside of the ignition wires, but the radiated field is proportional to the current, so the resistor trick should help. Finally, he could try using a piece of coax cable for the antenna of the radio system. The outer jacket and shield would need to be stripped off a section (say 1/4 wavelength, though 1/2 and 5/8 may also work), but that active section could be elevated to get it away from the engine, with the lower section of the cable keeping the shield. Maybe even paint the inside of the body shell with metallic paint and stick the antenna up through with the shielding ending a bit above the body.

[@robot797]

why do you think rcexl uses a braded shield around there ignition wires

[@Wanted1069]

Or maybe try running a BEC🤷‍♂️

[@ethanmiller5487]

Came here to say this as well!

The spot welder is a game changer for you

[@robertblunden7160]

Yes, I like the spot welder idea myself.👍

[@android444L]

Что за аппарат он использует?

[@paracelse2983]

It's in the description of the video​@@android444L

[@microbuilder]

Seriously one of the coolest RC projects on youtube!

[@noname-kh7sg]

Wait until you found one old video of a V10 rc model, its just not well documented

[@Mr.MashenIt]

I don't even do anything with RC and I have been subbed for near a decade. I just can't get over the engineering and refinement he always strives for. It's masterwork every time when it is finished.

[@zerri08]

Spot welder works so good and the fact that you actually take the time to remove the flashes is amazing!

[@roboman2444]

To help reduce interference to the servos/radio, try adding a few ceramic capacitors (and maybe an electrolytic too) to each Servo's power wire (+ and -). I've had amazing results with this in the past. Also shortening the wires to the minimum will help, or even run them through the chassis tubes, so they have shielding around them.

[@ryborg123456]

I like this solution, assuming the problem is due to inductance. I think it is. Just an LC circuit that needs tuning, ultimately.

[@psyched91]

Can confirm. Adding a cap on my FPV drone significantly reduced interference caused by big current spikes 🙂

[@PLASMA_2005]

🎉always excited to see a new video here 😆 Idea for the radio interference, perhaps some copper shielding could help reduce or completely eliminate that?

[@airgunnut]

on the voyger spacecraft NASA used aluminium foil to protect the external cabling from the very high voltage (40,000v) generated by jupiters magnetosphere

[@tatra7132]

I think that if the effects are not eliminated by protecting the electronic elements with a shield (Faraday cage) as you said, then another cause would be the sensitivity of the integrated circuits to an unfiltered power supply.

[@bwest6275]

@airgunnut that’s the narrative they try to promote #IYKYK

[@wodsonheleno]

Put a resistor on each spark plug wire just like the resistive spark plug car cables. if it doesn't helps (or for some margin), try to shield the sensitive signals as servo pulses as well with some grounded sheath (microphone cable). Electronics engineer here. Amazing job, bro! ps.: you would love to learn how to TIG weld. Trust me. I tried to learn it and it changed all my projects because now I can weld any metal, even tho, this spot welder does almost the same, because you don't need to weld thicker stuff. Consider it anyway! Cheers!

[@Pittsburgh-412]

There isn't many people on earth that have this high of a skill level working on these small scale rc vehicles. Amd your machine work is unbelievable

Your custom fab and repairs is what makes your projects great! As for the RFI, twisting and shielding the low frequency wiring works in the automotive world. And the shielding is connected to ground.

[@rc4lifebnsf]

That thing sounds wayyyy better with the larger exhaust headers with the larger collector. Nice

[@ck2503]

That is gonna be one fun problem to fix, I cannot wait to see your solution, as they are always so cool. And typically pretty outside the box.

My dude, what is it you can’t do? This is the coolest build I’ve ever seen. A spot welder? Dude, even the welds are to scale for an RC. Awesome👍

[@Pascal_Robert--Rc_Creations]

I believe old school rc radios were better suited for interference. Maybe try an old, long antenna radio instead of a 2.4gHz one?

[@darkwater72]

Antenna length should be tuned depending on frequency.

As Always JohnnyQ90...........your builds are exemplary in watching how You cut,weld,install,etc. everything! I've been watching your videos for years! And am always left breathless when it gets to the end! This video obviously........things just weren't going the way they should! Am looking forward to your next one when you've hopefully found the cause of the problem and your able to put a painted body on,and RUN that thing the way it was designed for! Kudos Sir! And have a wonderful 2025!

[@MarkHahn]

It sounds amazing! Im sure you can work out the radio issues by getting a higher end radio. My Nitro RC done the same thing and I made sure the receiver is completely wrapped in foam and not touching any part of the body. Thats is SO COOL! I cant get over the sound. Very cool

[@gruffrc]

Yeah I was was wondering if an ELRS system might avoid these issues such as the Radiomaster MT12. Would be interesting to try.

Do be honest I wouldn’t even have noticed the sponsor part if it wasn’t for that big bar at the bottom. This is most likely the most non intrusive ad I’ve seen so far.

[@mr3748]

Solution for the interference: If possible, try common ground between the ignition circuit and the RF circuit. Use a "pi" filter in the RF circuit. Otherwise, just use low Farad ceramic capacitors 0.1uF across ground and V+ as well as ground to servo signal wire. Lastly, put a metal mesh sleeves over the high tension leads, these should be connected to common ground.

[@AlmightyEye]

[@MultiBigDenis]

you have a digital radio control system, you can safely throw out the unnecessary mechanical compensation unit for the extreme points of travel on the steering machine, you can safely adjust the extreme points of movement on the equipment, removing the extra spring assembly, you will ensure that the response to the gas trigger will be clearer.

[@Silverturky]

It sounds so cool!!! What are you going to do to isolate the receiver from interference?

[@HBFTimmahh]

Johnny, the radiolimk radio is a rather strong transmitter. When you have it closer than three feet to the receiver it can overwhelm the receiver and other electronics on the rc. Keep the transmitter away from the rc when bench testing/working on them and you'll find less interference and glitching. I try to keep it a minimum of three feet away whenever I'm working on the rcs.

[@corsair149]

[@billymacomb]

You will need to add an orifice device to the oil cooler to slow the flow. Just like the coolant if there is no restriction the fluid will never have time to cool! Prolonged periods of use will degrade the oil. Did you ever come up with a design or an idea for a thermostat?

[@OnlyTheEd]

Did you try shielding the radio in aluminum foil? Basically making a Faraday cage?

[@laymanengineer7502]

I was thinking maybe some stainless woven heat shield around the distributor and wires like a loom to act as a faraday shield? Problem is trying to find something small and thin enough. Really nice project bro!

[@DhatLex]

Would love to see one in a car platform. Maybe modern or old school muscle.

[@brianlackie5093]

Really cool build. The engine doesn't spend enough RPM to engage the clutch. A heavier clutch shoe and softer spring might help. The clutch u got looks like 8 scale racing clutch, maybe try just a basic three shoe clutch and flywhee for something like a Mugen mbx with aluminum clutch shoes and softer springs or design your own

[@OldCurmudgeon3DP]

That spot welder seems like a nice piece of kit for it's use case. A little pricey though.

[@eightsprites]

Haven’t seen more than the thumbnail.. but that’s a really cool idea!

[@ukaszsmoa8416]

Could you do teardown of this spot welder, to show how it works?

[@clayrobbirds5361]

I’d definitely figure that clutch out. If it was me I would want full engagement at lower rpm’s for realism and save the clutch itself. Just depends on what you want to do with it.

[@bigfatgigerkid]

Awesome.... Damn that radio interference

[@TailSpinRCSpain]

A 'failsafe' would be a good idea, in the quadcopter/multi-rotor hobby we always have an emergency motor kill, if signal is lost.

[@LTV_inc]

What a cool project!

[@sheldonhall4572]

Try and see if there is something you could sleeve over the spark plug wires that could help cut the interference in the control system. Not exactly sure where the remote control sensor is mounted on the chassis try putting a ground to it or remount somewhere near the back.

[@ФеликсПеткун]

Автор привет у тебя такая крутая машинка с таким мощным двигателем, но когда ты ее тестировал, как то странно она стартовала необходимо будет сделать КПП с сцеплением по мощнее😊 тогда она будет плавно стартовать и поедет бодрее так как у нее двигатель много весит

[@ligius3]

Regarding the buck converter - this is a nice option as it outputs a stable voltage, but you have to make sure you don't exceeded the maximum input voltage. There are small regulator modules for motorcycles/scooters, they only cost a few bucks. They are a lot more rugged. The interference is a bit hard to track down. I would suspect first the point ignition / distributor cap. You can shield it in aluminium foil or replace it with a solid-state one. If that does not work, shielding ALSO the spark plug wires should help a bit. The radio module has to be moved away from any ignition point and preferably some metallic plate or foil should be between them.

[@TheDeveloperGuy]

About noise: spark plugs are a huge issue in cars! Changing to thicker wires was not the best idea. Last time the ignition died on my car, I checked the resistance to find out the cable was at fault. It had a nominal resistance of few kiloohms by default to limit the current of the sparks. (And the dead cable was over 100k?) So I’s replace that for starters (maybe add the series resistors as already suggested), and add some shielding. But the power line of the ignition must be filtered AF! Sparks are high-frequency noise sources, so beefy 10-1000uF caps are useless here. Use ceramic caps.
