@rctestflight how much torque does it have? Could it pull/tow you in the snow or on the sand ?
I'm building a power wheelchair I don't have all the kinks worked out..but I want to use hub motors so I can do 40ish
what song did you use for the montage at 7:45? the description is sadly incorrect. clicking on the link leads to a different song for me, and searching for the song on youtube leads to a completely different one, neither of which sound like the song used.
Hey, idk if you see these comments but what if you made it a little larger and heavier so you could either put 2 motors in the front and back instead of just the front or put 2 in the front and 2 in the middle with a support wheel in between the and then have a dead axle kinda deal in the back where all the controls and batteries etc are
Seen goliath in battlefield 5? Imagine this shit wired with explosives cruising at 70 km/h towards enemy tanks.
Every new episode of the snowcat series we are getting closer and closer to a flying tank
technically the RC tanks can already fly, just not controllably
*ground effect tank
Oleg Antonov enters the chat
The Aerogavin shall be real!
Mike Sparks will finally be validated
I'm actually surprised that it survived for this long, I thought the tracks were going to disintegrate at such speeds. Awesome stuff!
The rc snowmobile community has had the tracks going 60+ mph it's insane how the links hold up! Note they are not rc test flights tracks
3D-printed plastic is solid indeed
That was my first thought - that the treads would stretch at high speeds, and any wobble would send them flying.
😲
Yeah, I was going to say "all that weight and plastic gears!!". Good going.
Those dogs enjoyed the chasing of your snowcat more than the drone did.. haha.. by the way.. great project and exceptional explanation of the building and learning experience..
I don't think you get enough praise for the beautiful locations where you test and film and how good the cinematography is in these videos, alongside the informative and fun science and engineering. Great job with the snowcat and I think this video convinced me to move to the PNW!
while he terrorizes geese and rips up the lawn at the public park...
@@travissabo8792bro is a lawn 😅 what he ruining??
I was so confused by the supersonic dogs running past and coming back instantly until I realized there were 2 puppers. Great dogs and fantastic build!
These snow-cats seem to make great hound baits to get the doggies running
Taking a hit from that snow-cat looks painful! Hope the dog is okay.
@@Mattle_lutra I was gonna say this, that thing's pretty heavy and getting hit with the moving treads can't feel good.
Imagine if they mounted a camera on one of the dogs :)
@Repent and believe in Jesus Christ Thnaks for this irrelevent fictional interlude.
The chase footage with dogs was very fun to watch. I thought outrunning dogs was impressive enough, and then you nearly doubled its top speed… well done.
Also, conversions to km/h:
9:32: 11.95 m/s = 43.02 km/h
13:06: 12.57 m/s = 45.252 km/h
13:38: 19.17 m/s = 69.012 km/h
15:19: 22.24 m/s = 80.064 km/h
I prefer m/s since they're much easier to visualise, but the unit most people in the world are most familiar with is still km/h.
Yes, definitely very cool, almost looked like a video game to me)).
1m/s = 3,6km/h
That's insane ! Basically highway speeds there. I'd definitely be scared to drive at those speeds without generous distance between me and other vehicles.
Also the acceleration! Probably because it's relatively lighter than a motorbike.
I wonder if it could reach speeds of gas powered ones on a tarmac with an appropriate track / wheel?
@@dmitriiar2178 definitely felt like video game footage with the drone recording!
i love how you show the metrics of the screws and the exact driver model and etc. Also your methods of measuring and drilling. It's something a lot of other makers leave out, which makes people like me who want to learn hands-on techniques really frustrating. You give me a better view of how each fragmented piece of knowledge can work together. Thanks whole lot!
I am not into RC/drone stuff at all, super into the tech aspects (the batteries, motor, 3D printed frame, etc) but nothing I’d do irl. But this channel is insane, It’s making me interested in stuff you love just because of how you put these videos together and how much effort you put in
So insanely quick!!! Definitely the world record. It's mad seeing the plastic start becoming brittle and chipping off in the snow test. I wonder if there's any real solution for that?
Solution: don't use plastic?
Softer/more flexible plastic, or tougher plastic. Something like Nylon.
TPU?
@@ldub0775 ah yes, just add a zero to the cost. The optimal solution.
Polyurethane
Dang, that IS fast.

@@YoursUntruly lol
I've thought about doing this but seems like the bolts holes that strip out are always in the worse areas where I can't put a drill. But happy to actually see this in use. An old mechanic told me about this but never have had to use it yet. But one day in sure it will come. Glad to know if will work Great video
Mannnn, this thing is awesome! You should totally make a version with rear suspension, either with some small rc car spring or another soft filament wheel. Since the thing is driving almost always in a wheelie I think that have the rear axles dampend will really improve the handeling and make it not flip. Also if you go for a soft filament wheel, the torque will be latend but also released faster, making it so wheelies are easier from a start. Which would be cool in my opinion.
It's amazing how stable this is at high speed on grass, it's been great to see your snowcat evolutions
First thing I noticed... Other than happiest dogs alive finally giving chase to a worthy adversery XD
it was well built, motors are sync and the board is long enough to reduce the derivation
Probably too much of a risk but I would love to see you try and drive this across a lake!
Its likely it could stay on top of the water for a short time because it's mad of plastic and the tracks are reasonably wide. Probably not waterproof though...
Some pontoons to keep it afloat to test?
@@Gainn nah, this thing has enough power to skip right on top of the water, I'm not sure how stable it would be. but the speed is more than enough.
@@MrGuliton I'd agree it has the power. The problem is if it stops.
@@Gainn the problem is *when* it stops
Brilliant work! Thanks for sharing it.
Awesome build. two things this reminds me of. First the rc mini ww2 tank busters some were tethered. The really cool thing is that this model it can be anyway up to move forward - it remined me of the game rollcage, the way it can move forward- no matter if it is upside down.
The sand issue reminds me of the different approaches the AK-47 and the AR-15 take to handling debris. The AK has lose tolerances so sand can't get stuck anywhere. The AR has tight tolerances but uses those tolerances to keep the interior well sealed off from debris so long as you have a mag in and the dust cover closed. When you do something in between, you get the issues you had with sand scraping the motors.
The AR platform rifle tends to perform better in the muddy and wet environments then the looser tolerance AK style rifles. While the AK performs better in the sand. Both perform pretty awful if you let them get really wet and then freeze though 😂.
@@BodilyFunction I've heard the best thing you can do for freezing conditions is to strip all the lube out so it can't freeze
@@Synergy7Studios it kinda depends on the kind of lube. A bit of oil based lube is ok in some areas but water based lube is no go. It also depends on actual temperatures aswell as just where the water gets to.
@@BodilyFunction I just remember the soldiers in Korea found that their garands ran better in the harsh winters when they ran them dry. Their oil must have had a high freezing point.
@@Synergy7Studios makes sense but also garands are a bit different to ARs.
I've built skid-steered battle-bots and the best upgrade I ever did was adding a steering rate gyro. (just a V-tail mixer and a tail-rotor gyro to start) Took a bot that was a nightmare to drive that never pointed in the right direction and turned it into a drift master.
I think doing the same with the flight-controller software will dramatically improve high speed stability and turning.
Yes! As a bonus, add in pitch control to hold a perfect wheely for max acceleration!
@@ericcmcgraw thats what i was thinking, since he already has an ardupilot install. I THINK Rover has pitch control in one of the modes. I know it has yaw control that countersteers when you get too much roll because I'm using it right now.*
*although it's a little laggy and gets into weird oscillations on rough ground that lead to rollovers anyway
You're a really good engineer. I love how you identify and fix problems without complaining and bitching. You just get shit done.
Outstanding achievment and vid !!
Especially the part with soundtrack + DOGGY's !!!
13:33 are we just going to ignore the "Strongest Shape" he drew in the grass?
thank god someone else saw it too
FYI, you can also use thinned down silicone caulking (with 30+% vinegar, mineral spirits or toluene) as a waterproof coating and it can be removed/doesn't flow into everything quite as much as epoxy. I've seen that done on some outdoor equipment I've dealt with in the past, that had to be repaired onsite. One thing we did though, is use a multimeter on the wet caulking and choose a brand/type that did NOT have any continuity when wet.
There are also hard acrylic conformal coatings designed with high electrical resistance as well.
that one dog is fast as hell, he went counter curve on it and caught up to it twice lol. great video man, this brightened up my day, i needed that
Most EXCELLENT ADVERTISING!!!
Absolutely flawless.
The snowcat series has been amazing to follow along to! Any reason why you aren't doing any more batches of the kit? cost? hassle? - either way, this project has been REALLY cool!
Yeh, really a shame this isn‘t a product you can buy. Maybe outsource the whole packaging and distribution to some rc-company?
I‘d love to build one if I ever find some time to do so..
How much would you pay for this?
@@johnjallen The initial buy in I remember being good value, I would have jumped in if I wasn't tight on cash at the time
Looked faster than 15mph
Super cool! Have you tried using 58D TPU for the tracks? Extrudr even has one hard TPU mixed with carbon fibers which should make the tracks semi indestructible.
I think he's using cast tracks and not printed so they sould be plenty strong as is, it's just that hey are too wide to cope with the forces of such high speeds on solid ground, though on deeper snow wich they are designed for they seem to do just fine
Lmao, watch the latest Zach Friedman filament video. That stuff is awful
@@FayezButts Are you talking about the "CF-TPU by SmartMaterials"?
Because that's a completely different filament.
The standard hard TPU from Extrudr is one of my favorite Materials ever.
It's super tough, easy to print and I'm pretty sure that the CF stuff is awesome too.
the dogs are so excited ! they are enjoying the performance of that tank lol
Outstanding build and dronework!! BRAVO
I laughed like a maniac when it effortlessly popped the wheelie at what seemed to be the max speed prior to the upgrades. Awesome vehicle, very scary as well. I feel we are seeing a battlebot origins story unfolding before us, even if extreme speed may not exactly be a factor in the arena... Perhaps the world is ready for battlebot jousting; then we have a sure winner!
These look fun to race. I'd love to start a racing league with home-made rc vehicles like these. It looks like it'd be super fast but would need a lot of skill and finesse to drive at their limit
Just make sure everyone uses the same motor as the only limitation. And then let them race!
@@AndreyAntonchik Why not open class? Push it to the limit. May the best builder win!
@@pineapplepenappoodlepen while fun, that also quickly becomes "may the builder with the deepest pockets win". Definitely would still want a class with spec limitations in order to get more people to participate.
@@pineapplepenappoodlepen People would just build buggies or truggies similar to what you can buy right now as those are basically proven to be the fastest designs.
I know Paul Short from NZ!!! He taught me everything I know about drones as we live in the same area of NZ. Awesome friendly guy to know, knows his drones and electronics through and through!
Nice video! You should make a 4 motor version to even the weight distribution, widen the tracks some, and lower the track depth a bit. Awesome project!
its awesome to see way more uploads. ive still been building ground effects rc planes because of you.
Let’s see some of them!!!
@rctestflight I'm curious how much did this cost you to build this little RC tank?
@@Nightowl5454 easily $1000-$2000
I never heard of a tank so fast it needed a wheelie bar. This is awesome.
Awesome build!! You’re a genius! Super impressive!

Doggos chasing the snowcat are so cute. They are probably so happy to chase and run at their limit.
did you not see 8:46 ? rip doggo

Love onshape! Cant wait to check out the file
Maybe you can use the IMU in the ardupilot unit to create a coarse type of ABS, but for acceleration rather than braking. So if the RPM of the motors exceed the vehicle speed by some margin you can forcibly slow them down to maintain traction. I think part of what makes it so hard to control is that if you turn hard right, your left track can lose grip and net you will actually turn left. Traction control could help what that, especially on the ice.
To reduce internal friction you could print the track guides out of a filament composed partly of teflon. There's a couple out there now and supposedly they feel so slick that they almost feel waxy.
I also wonder if you could reduce the air resistance of the snowcat by deflecting the airflow upwards before the treads. Downside would be reduced downforce and therefore traction.
The FPV shots were exhilarating, great show of the speed!
well great job man on your project and yes im one of those unlucky ones that are here late and first time but glad you make your dream come true
I swear this has become my favorite UA-cam videos. I respect the brain power you would need to do everything he does. I love it
This chase footage is the best I've ever seen, and I've seen a lot of them. But then the video goes on to show more awesome fun stuff in snow and sand. Seriously cool stuff.
The M.1000 is pretty nice for what it is. We have a fully kitted out one at work. We don't use it for metal, though. That edge on the aluminum looked rough.
Crazy fast! Love the drone footage with the dogs running with it
If you add skis to the front (rear) it will prevent the digging and keep it riding above the snow. You can also use them to add directional assistance.
Love this series!
Would you have better luck if you could find appropriate rubber tracks?
And swap it to motors as the front to help with weight distribution?
The only issue i see with this is that the side of the track in contact with the ground should be under tension, so a long toothed belt would be needed to transfer the drive from the motors up front to the track drive sprocket at the back.
That said, the track tension could be high enough for it not to be a problem! It worked well in the snow going backwards! 😄
I like your calculations for the motor requirements, it pushes a skateboard at 3:1 so direct drive rc should be fast! It’s the best kind of engineering! and I’ve got to say it’d be more than capable of running with most rtr cars too! Some drag or even a flat track racing between cars and the tank would be entertaining!
That's so cool....!
What about adding fins or spoilers to keep it pressed to the ground?
Omg! I just got hit by so much nostalgia! I currently live in North Carolina. During the part in the icy snow i was sitting here thinking "Is that Snoqualmie beside I90?". And then the part at the beach north of the entrance to the locks... That's my home! I miss Seattle. I left for reasons and Seattle isn't the Seattle i grew up with anymore but i still love it. So funny that I've watched multiple of your videos and had a feeling that where you lived seemed very similar to Seattle, but maybe you were in BC or something? Who knows? Alot of places look like alot of other places around the world. But this video answered it for me and that it happened to be where i grew up is awesome.
Look at the drill bending @ 2:48 😱😱😱😱
That thing is seriously insane. Have you ever considered using brush on Silicone conformal coating for your electronics? I have had very good luck with it and one advantage is that if you need to do a component level repair it can even be soldered thru without much trouble. It is much less permanent that the epoxy seems to be. I saw what appears to be a bulldozer on the floor of your shop....hoping I can find a vid of that on your channel now!
Ahtrack-ted all the kids and dogs in town.
Nice build. Thanks for sharing.
Weekend Stuff
i do have a soft spot for tracks. idk what it is about them but theyll always be my favorite impractical drive setup.
That was incredible. The drone shots. Wow!
That was really cool. Great design. I will say that when I design things for 3D printing, I try to put things like ribs or runners on all large surfaces to give them a bit of extra strength.
I dunno if you want to try it, but I'm wondering if the tracks are going fast enough to aquaplane on water. It might be able to cross a pond.
I've always wondered if you could put this type of equipment onto a snowboard to help for flat surfaces or even uphill.
Given that your feet sit spaced apart there is certainly room to place the mechanisms.
Hell you could even look at some method to raise / lower the tracks off the board so it doesn't affect normal boarding. Then when you need it can be places down and push you along
Would love to see you try!!
That so sick tank I ever see even when n sand love those roosters if he build seal no dirty or sand get in then your golden keep up great work
I hope you build a marketable version of this someday. I would pay similar pricing to an XMAXX for this. Serious fun right there
Man that looks so BRUTAL but yet so FUN!
Strangely the first thing that came to mind when seeing the drone footage were the tentacle monsters (Mimics) from Edge of Tomorrow with Tom Cruise :D
I think the slight upwards angle, sleek "cigar" shape, fast paced filming and especially 2 colored tracks contributed a lot to that.
Also the video was done great with the music and action drone footage!
I hope this takes off like a rocket, creates a new subspecies of vehicle type and will get it's own small community/scene!
I read that as testicle monsters from Mimic😅
Had to re-read it realize what you were talking about 🤦♂️
it looks like that scene at the end of the movie with the water and the damaged plane.
@3:10 maybe it doesnt matter or maybe im misunderstanding, but i would slide a hella-thin washer onto the shaft before installing the coupler. That would help eliminate gouging if there is any wonkiness, and reduce any sidewall friction when the wheel is supporting side-loads.
Love it. It's a scary thing you have there. The part with the dogs, people, and music was beautifully done but, I was flinching pretty well.
That is incredibly fast. i think it might be worth checking out giving the middle rollers a dampened suspension.
Also, I've been using onshape for about two and a half years and I can confirm that it is really good. they also have a free learning center that can very quickly teach you how to 3d model
any suspension would reduce the acceleration and the battery, to much energy lost in the suspension. Maybe if you just find a way to allow suspension only when not accelerating or under 90% of max speed, since suspension could improve durability at max speed ^^
@@alixhascour1715 I wouldn't be so sure, if it has more constant contact with the ground across the length of the tracks it could actually improve on acceleration simply due to better grip, especially with the high torque of these strong motors. Battery life loss probably will be mostly negligible.
You should try to add an IMU or distance sensors and limit the rpm while accelerating so it doesn't go into a wheelie for stability. Kinda like traction control
Its so violent in motion, i love it!
That aerial footage with the dogs chasing it was amazing!
I have a suggestion, maybe try out tracks printed in tpu, it would give them a little more durability and wear resistance factor, a little added flexibility as it seems one of the limiting factors are the tracks, so maybe using tpu printed tracks would benefit it, another thing you could do is make little servo controlled downforce wings that pop up at a certain rpm and fit flat and flush to the center of the body and between the tracks so they aren't damaged when not in use in the front and back of the vehicle, it could help with speed and control
The tracks are cast. Idk what exact material they are, but 3d printing will be worse.
Doesn't tp lack stiffness and strength though? I think you could get a lot of mileage out of a dual-extruded composite of tpu and something strong like PC or PA. But maybe figuring out how to make the best gcode to tune the mechanical properties you want is a PhD-worth of work.
@Charles Lambert TPU 3D Printer Filament Definition Explanation (Thermoplastic polyurethane) is a type of flexible and elastic 3D printing filament. Its rubber-like elasticity, resilience, and durability make it suitable for uses requiring impact-absorption and a soft-touch surface.
@VulpeculaJoy they are not cast, they are 3d printed, he shows in previous videos he 3d printed the entire tracks
Couple things...
1) I'd love to see some sort of TPU track option, both to further cut noise, as well as making it combatible with concrete, asphalt, and packed clay/dirt
2) can we see if it can hydroplane?
3) that "digging a nest" thing is awesome, and reminds me of a way that fullsize tanks can "bed down" for extra cover and concealment.
Imagine this thing as a remote-operated anti tank mine in a non-permissive enviroment that precluded manual placement... Drive some in manually and then remotely "dig them in" to get them slightly below ground surface... There's plenty of room in the design for a simple pressure pad and an EFP- and the underside of a tank and its tracks are the most vulnerable parts.
You may have accidentally invented an effective anti-armor tool
Love the drone footage!
Awesome! I started to think about centrifugal force, track linkage bearing friction starts to be a thing I guess at this point. Can be reduced by lower track piece weight or some suitable bearing in the track pieces.
Bearings arent possible with all the dirt and sand they fail very quickly, even real tanks and bulldozers dont have bearings in there tracks.
Mechanical roller/ball bearings would not be a good fit for this purpose, but a bronze bushing would fit this purpose very well
@@jonasstahl9826 You're right that the large tracks used on excavators and bulldozers don't have them but the OP's point was about the centrifugal forces tracks experience at significant speeds. Even fairly fast tanks are unlikely to face stress from centrifugal forces that even approach the forces from the usual driving torque acting against the vehicle weight/inertia and a bulldozer clearly _never_ would.. I don't know if bearings are the only solution but I don't buy the idea that sealed bearings couldn't be *a* solution -- if a slightly costly one.
@@whatelseison8970 The problem is the weight of the bearings, if I remember correct each of his tracks has 60 links, you need 2 per links, means for both sides you need 240 bearings.
The cheapest sealed I have found are roughly 0,60€ means 144€ in total. Also the weight lets say there are 10 grams each that makes 2,4kg/ 5 pounds.
You also need enough material thignes to fit the bearing, that makes it even heavier.
Damn! I’m so jealous of that cnc machine, if I even had access to one I wouldn’t have nearly half the issues I have with building any of my rc projects!
Look up your local maker spaces and go talk to companies that might have cnc machines. My local machine shop went belly up, but guys that worked there put up their own company and owners dad that was going to retire still works there as a hobby and to help out. I can get machining jobs done fore fraction of the cost since i'm not in hurry to get anything done so they can fill their schedule with my jobs when there is spare time around in shop. Same thing with welding jobs and anything really. Most welders dont mind doing quick job on the coffee brake or afterwork if its not that time sensitive or large and usually pack of coffee (around 5€) is fine for them as they get more life juice into break room. So my advice is to talk to people. This is how you learn about possibilities around you.
For making RC parts, most can be done with basic CAD (cardboard assisted design), jigsaw, hacksaw, grinder and some files. Holes with drill press specially if you are using aluminum. Just be patient.
Use the no limit software. Turn the abs cutoff time limit up. Turn battery amps and phase amps up. Turn on field weakening. Also connect nrf51822 for making changes over Bluetooth. Then connect the controllers over canbus so they talk to each other.
That is so cool and fast. Oh and Scary!
Hilarious when the dogs were chasing it on the field .
How cool would it be to sync the quadcopter to the car so that you can drive in 3rd person view?
Very interesting project. Great work. Enjoyed watching. 🍻👏🔥
And you say putting oil into the usb-c prevents the port to get unusable until coating?
This video was really entertaining… I can only imagine how much fun you had making all of this. You get to be in the hobby and here on UA-cam as a content creator at the same time. Pretty fun you should consider yourself so lucky. Anyway it was fun to watch big thumbs up from me
Imagine this but full scale. You're a russian soldier just trying to not die because of vladdy and then suddenly a tank with a top speed of 300kmh /180 mph approaches
AMAZING! awesome build and i love how RC cars double as exercise machines for dogs.
It's an rly cool rc! maybe you should also explore the idea of a hole digging rc, it was quite impressive how fast it dig itself into the snow and sand
Damn how am I so early? Also damn that's fast
Do you think you could improve this if it had a kind of independent suspension/sway system? So when you turn, it would kind of lean into the turn, and angle the tracks to sort of carve its way through turns? That way it wont high side and flip over if you turn too sharp
Damnnnn you did hell of a work there 🎉
I loved when you dribbled those dogs there😂
Super impressive build! Can't believe it can handle that deep powder.
Seemingly small mistakes like epoxy in the usb c slot are the ones that can be the hardest to overcome. Unforseen, unpredictable, and it completely throws the project off the rails until it’s fixed. Sometime you don’t have replacement parts and the fix is going to be a whole project in itself. People don’t appreciate how satisfying it is when you find a good solution to something like that. From the outside it’s nothing, but to the person encountering it, it’s like defusing a bomb you didn’t see coming. Cutting a bit off the end was genius
Long time viewer, just payed for your bandcamp tunes, love your stuff!!
So cool! Great build.
I've how it flips and keeps going. AWSOME
I love the add inserts very well done 👍
I'd love to see you design a Battle Bot 🙌 Thanks for the video! Awesome build!
Snow cats usually have tails. maybe yours can also be done so that it does not roll over when moving quickly, and if you still work, then the tail could help turn. Like the rudders of a ship. A tail that would drag behind the cat on the snow/ground.
Hi. Love your channel. Do you think a wing of sorts on the front for some down force would help with the flipping? I wouldn't print it though 😁
This thing looks like the Tasmanian Devli from Lonely Tunes when it goes throug the deep snow :). Awesome build!
How did you work out the speed differentials between the left and right sided tracks? Just curious.
Now id love to see u iterate on this and make it super robust, easy to repair, easy to build, water and sand proof and maybe also work on the tracks for different Environments. Would be content id enjoy
I did a lot of work to my e-revo to get it up to 70mph yet I think this is superior in all departments. 6s lipos are scary efficient I can't even imagine what 12s would do
Subscribed purely because you listed out every part. Really makes me want to go fabricate something.
The dogs chasing it was sweet!
the droneshot with the dogs was very cool
