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!
🎉always excited to see a new video here 😆 Idea for the radio interference, perhaps some copper shielding could help reduce or completely eliminate that?
on the voyger spacecraft NASA used aluminium foil to protect the external cabling from the very high voltage (40,000v) generated by jupiters magnetosphere
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.
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.
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.
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.
u can use a soft metal like copper and a hard metall to build a clutch, but dont forget u need a high pressure to have a not slipping clutch, like that maybe u should use organic stuff like in the real car clutches
A buck converter + rectifier is probably more efficient than most series or shunt style regulators used on motorcycles. Series regulators are basically just linear vregs. Shunt regulators are even worse. For peace of mind, you should spin that BLDC "genetor" motor at the highest speed it will ever see (engine redline), and then measure the output of the rectifier with no load on it. As long as that is below the maximum input of the vreg, you should be fine. Or, you can look up the motor's KV value, and divide the redline RPM it will see by that. That "should" be the maximum voltage it will output.
It may be RF interfierence or ignition coil backfeed from the ground up. This can be tested by installing a simple diode between gound and positive leads at the radio connector.
Always a pleasure to see a New upload from the Best TH-camr, JohnnyQ90 !!.. Thank you for all the great videos my friend since it's much Appreciated. 👍🏻👍🏻😎
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.
I would sheath the ignition leads and enclose the radio receiver in a faraday cage with only the antenna being exposed. Additionally, since they appear to all be running on the same power source i would suggest trying a ground loop isolator/filter, they are quite common in car audio applications. The success will be unpredictable though since the crystal oscillators in digital recievers are very sensitive to emi, so i would prioritise shielding. I would be curious to see how the rtr petrol baja buggies combat this.
I think sadly you are going to have to put a wire for steering instead of the radio connection. Also aren't clutches not supposed to slip. your slips so much i=you could push it back word and your engine still run???
The spot welder is a game changer for you

Seriously one of the coolest RC projects on youtube!
That spot welder is kinda cool how well do they hold.
I enjoy these builds and watching you make the pieces
BEST CHANNEL ON TH-cam
9:50 *amazing v8 sound* plus all the nice details 🗿👌

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

always waiting for these project

Love your craftsmanship. Such clean work.
I believe old school rc radios were better suited for interference. Maybe try an old, long antenna radio instead of a 2.4gHz one?
This particular sponsor seems to be everywhere this past 2 weeks.
It fits perfectly, especially with the sound and design of the engine.
I liked new weld toy
This is really impressive ! nice work !
Maybe the exhaust gases will cook the rear tires.
Which spot welder are yoy using bud?

increible como siempre Johnny
Love these rc engine vids!

Amazing job👏. Congratulations👍. I have a question. What brand are these tires?
Some gremlins in there, you'll find them. 👍💪✌
sounds like a monster truck

Γειά σου Γιάννη με τα ωραία σου!!
สวัสดีครับ
2:40 throttle Not Full Open. And btw this is hole is to small for that Engine 😂
What is the name of this metal welding machine?
There is a link to it in the description.
Are the wheels or wheel hubs not round? Seemed like there was wobble on all four corners when you were testing at the end
Probably vibration showing up in the frame .rate

Always excited when bro uploads
Very Cool.
This is getting exciting!
I have complete confidence in you, and all your supporters. Y'all will eventually solve the interference problem.
Awesome🎉
why not buy a stick welder or a mig welder?
Здравствуйте! Как называется данный сварочный аппарат?
no 3

Nothing like a 20k dollar rc car lol

Thanks to the good carburettor this engine is a great example of turning fuel into noise. Nothing else.
Change the brand of remote control, the NB4 remote control from China has good anti-interference performance
i ghost to the down cool
nice project, but you have to learn a lot about machining and electronics. keep up the good work!
Nice work, but showing every bloody spotweld or turn of a screw is such an ugly style of video editing...
I enjoy it. Some of us...
