Nice work. I built a quarter scale buggy back in the early 80s with a homelite chainsaw engine. Wish I had 3d printers and arduino boards back then. Still have the car on a shelf.
It’s amazing that you created this from nothing yourself. All credit to you. It’s great especially when you open it up! I was just thinking to myself ‘well, it’s slow but it’s still brilliant’ then you turned on the gas and I thought wow that’s so cool!👍
Parabéns pela idéia e pela construção! Estou deitado me recuperando de uma cirurgia e tive a idéia de um Carro RC com motor de motosserra, mas antes resolvi pesquisar se já existia e encontrei seu vídeo! Belo trabalho e fico feliz que disponibilizou o projeto para os construtores caseiros! Tenho vontade de fazer um RC Chainsaw Engine no estilo Ford Focus WRC AWD hahaha Congratulations from Brazil!! 🎉
The previous tenant of my house left a chainsaw, no idea if it works. I think it might be time to find out. If it does, I'll have to go over to my dad's and see if I can't dig out the old kid sized ATVs to cannibalize... this is summer is shaping up to be very interesting.
@@outdoorsadventures3722 Eh, figured there was a reason he left it behind. Not that I've been actively looking, but if I came across a used saw at the right time I'd definitely give it another go. Gonna need something soon actually, my brushless ESC caught on fire last week, so no more hucking the DT-02 around the neighbourhood, for a bit.
Now it just needs a pov camera, some paddle tires, and sand dunes ;) nice work I dig it. Great way to deliver pizza or whatever at little Sahara ha ha.
I was wondering two things the 1st if it was possible to have the 3d project of the servo box and the 2nd if it was possible to have the code you used for Arduino. Thank you very much and wonderful car
I don't know when you built it but since probably 2016 there's been mass market electric RCs that would leave this thing in the dust in terms of acceleration and top speed. Maybe not so much in the run-time but batteries are so much cheaper these days that that kinda doesn't matter. On the other hand those electrics don't have that delicious chainsaw sound.
Needs larger tires for sure. Plus chainsaws like higher rpms . so I would gear it way lower still with the bigger tires. I would know a few people who would love to run those on the personal dirt track.
That is SO COOL!!! How long did it take for you to make it? It's definitely the perfect size as if I ever built one from scratch, it'd definitely be 1/5th scale. As I think that's the perfect size before it gets too big. Is there a reason you stuck the steering in front of the axle instead of behind? I'm only thinking that it could be damaged if it got hit or it ran into something, that's all.
Thanks! I would say it took me about six months to design and build the first iteration of the car. Back then the front suspension was different and it had different electric components. Plus there are many other updates made since then so I'm guessing the car will never be "finished". In my opinion this is the reasonable maximum size for an rc car because it becomes difficult to transport with a normal sized car. The only reason the steering is in front of the axle is that there was simply no room behind for the linkage. You are right that it could be easily damaged in an accident. Also the steering geometry would be better if it was behind the axle. I was eager to have a test drive with the new servo setup so this is the configuration I ended up with. At some point in the future I might modify the frame a little.
Can you tell me where I can purchase oversized servos for a project like this? I want to weld a car with mild steel and use a similar power plant. I’m just not familiar with servo sizes. Do you know what you would call a servo like this and/or what size it would be? Thanks so much and great work.
Check ebay for chinese Happymodel SUPER 300 / SUPER 500 servo. It's the biggest servo I have come up with. Other option would be a Tonegawa Seiko servo if those are still available somewhere
The shock absorbers are some modified gas struts (oil filled and shortened). Calculated output of the steering servo is about 140 kgs, I have not measured it though.
If you took a shotgun shell that was only loaded with gunpowder, could you fire it into a compressed air tank to create pressure which drives an air motor? So for example, this car would have five shotgun shells which fire into a tank which powers the car. When the pressure in the tank falls below 50 psi, it automatically fire the next shell.
Nice concept rig, but racing 1/5 scale stadium truck, I'm gonna need 3 times the steering speed, and about 50° steering angle. This ain't a dis, just a thumbs up and a keep at it from an old guy that's been into RC for about 40 years. Look up nitro tether cars. Have fun
hello , nice project, i would like you to ask few questions: 1) max speed 2) gear ratio 3) rpm/torque of the engine (if you know first hand) thank you so much :)
Hi, and thanks! Here are the answers: 1) I have never measured the actual top speed but it may be calculated as follows: 2) The gear ratio is 9,63:1 3) According to Stihl the maximum power of the engine is 2,6 kW at 9500 rpm. The maximum torque is typically at lower rpm than maximum power, let's say it's at 6000 rpm. Because we don't have the exact power curve of the engine, we assume the power at 6000 rpm to be 2 kW (may be less than that). Now the max torque can be calculated and it is 3,18 Nm. Rear wheels are 11" in diameter and if we assume that the engine is running at 9500 rpm, the top speed of the car would be 52 km/h. In reality the engine should be running at even higher rpm (if it's tuned properly) and the speed should be around 60 km/h.

revamp it
Would love to see it man!!! That's awesome

i loved how you explained the servo mechanism :D
Awesome build! That bent front right rim shows how much fun you have had with it! :D
You have to do a top speed run with it. I'm sure others are curious as well.
That servo is amazing!
Now there's an RC car you wouldn't want hitting your leg. Well made.
What a beautiful place to live. And what a nice build
Really nice and I think can be further improved by adding negative camber at the front wheels to increase practical cornering speed
That is some really great work, one of my biggest challenges is trying to figure out how to turn a large R/C. Very cool project !!!

Nice piece of at home engineering. You have some talent.

Well...? Did it work?
@@matthewclark6239 Haha, unfortunately no. The Husqvarna had zero compression, and a piston kit to fix it cost as much as a used saw that ran.
@@K-Anator that’s sad

@@K-Anator you can get chainsaws at yard sales for really cheap I've gotten 4 at once for 20 bucks and only one did not run from a bad coil
That thing is massive dude, that’s awesome
FANTASTIC BUILD FOR YOUR EFFORTS, WELL DONE.
Ave idea . Liked seeing the hamdle in the cab
Now it just needs a pov camera, some paddle tires, and sand dunes ;) nice work I dig it. Great way to deliver pizza or whatever at little Sahara ha ha.
Rack steering is great design. Modern full size Autos using electric steering. Your software and mechanical engineering is good.
I never thought about that! Badass brotha, that's an awesome ide. Great fabrication skills too!!
This is freaking awesome man I have a hpl 5b I have often thought about building my own chassis for it good work man I love it
Wow , i like the repurpose of the parts , dope 👍
Not to bad!!! It6 hard to make something from scratch. Much respect.
Very beautiful place and rc model!
Wow that looks like it built really nice looks like it’ll last forever lol. Awesome
killer work on the servo! great job man!!!

Nice. Combustion seems more real than battery power. Love seeing 2t smoke and smells good too😷😀
Biggest problem with this is that it's not in my shed! Nice work brother! 🙂

On the other hand those electrics don't have that delicious chainsaw sound.
Very nice work, man. I love the sound of it. Chainsaw on wheels lol.
2 scared to hit the throtle
Hello man,
this is awesome, I love this. Do you have any plans for built it? I can pay for it...
GOOD JOB
Can it have a smaller rear axle sprocket? I got the sensation that it can be faster. Great job too!
This is pretty cool what you made. 😄 My only suggestion put some wider tires on it for better traction.
Nicely done man, very cool 😎
Thats pretty neat. Thank you for the video.
I like this thing. Sounds like a saw for sure
Great build. Sounds like my like my little Peewee i had as a nipper.
Incredible job! I love it and I’d like to show you how to drive it sometime
So you have driving school?
Nice build.
Incredible work
Not a steering servo, its rack an pinion, very cool! Would love to have the CAD files!
next, adapt mower blade, your tops buddy. great rc buggy!
really nice car and video!
Thats beautiful, what an inspiration!

The steering servo design is Bad Ass!!!
Handles and runs as good as it looks (:
Reminds me of the Raco 1/4 scale cars! Love it!
As of right now there's a new need in my life.
What engine is that i was wanting to use a sthil 500i engine that fuel injected for my baja
Nice build man
RCtestflight did a longevity test of some RC cars. They lasted a few weeks I think.
I give this one 10 years.
This is amazing but how did you Create the clutch system ?
This is awesome, i love that engine sound.
Wow thats pretty fast, imagine a V6 made of those
I wouldn't mind having one of those running a Saito or OS 4st on gas. I would think a 150 would do the job.
thanks.
That’s the way the hobby should be nice work 👍
Awesome build man !
What song is that playing?!?!? It sounds like good trance.
Cool build. You need to build a full size.
Bravo excellent Job I give 🏆🏅for job well done
Fantastic job 😎

@@willaa303 you rule 🙏🏻
50cc rc car, that's freaking massive
How did the front inside rim get such a big bend in it???
That's the result of one of the numerous accidents I've had with this car.. don't remember what I hit that time though lol
what are the shock absorbers?
how many kilos is the steering servo?
The shock absorbers are some modified gas struts (oil filled and shortened). Calculated output of the steering servo is about 140 kgs, I have not measured it though.
Great build.
this is awesome, you just got another subscriber!
Home grown RC 👍💪😀🇬🇧
Should've left the chainsaw blade on the rig.lol. cool for sure chase the bears away
how does it break
Steering servo ?? How 🤔
Love the engineering
That expansion chamber looks pretty small for a 50cc
If you took a shotgun shell that was only loaded with gunpowder, could you fire it into a compressed air tank to create pressure which drives an air motor? So for example, this car would have five shotgun shells which fire into a tank which powers the car. When the pressure in the tank falls below 50 psi, it automatically fire the next shell.
That's awesome! Good job. Whats the top speed? Why go so slow in the video?
Thanks man! Top speed around 60 km/h. The driving space was very limited in this video so it was not safe to drive any faster
Hi, did you share somewhere the arduino code ? ( PID and Receiver-Arduino link )
Really interesting project! Looks great. How much is this car weight?
Thanks! It weights 41kgs / 90lbs.
@@willaa303 wow weighs a lot! Nice.

Mad skills. Impressive.
Make more videos.
I’ll be looking for the video where hopefully you actually open her up. That thing is sick
Dude that servo you built is fricking awesome man.
@@kravenkrawlhobby5438 Thanks!
The sound is fking awesome!
Good job!
And what about the camber of the front wheels? It's wrong.
Not optimal, but balloon type front wheels can handle it.
Is a Solidworks model?????
10 out of 10 bro
GREAT JOB
Very Innovative project 👌👏
Can you tell us Arduino how to setup ?
In this case ?
How much you charge to make me one
Whats the top speed?
Quelle est ca vitesse Maximale
cool build but really kind of slow. Maybe change some gearing
what! this thing is amazing!
I would name it flip fire.. on account of what its destined to do.. lol
No differential?
No differential. It has a solid rear axle just like some smaller ATVs
Like to see it wide open on a long road
