This might even hydro-plane over water like those high power ski-doo’s.
If nothing else, I'm sure we'd all love to see it try!
i was thinking the same shit xD
It will definitely hydroplane. With those crazy motors and batteries and the huge surface area on those track I would really like to see it on water. Not sure how turning would go…
i have one of those ski doos and i can confirm that they hydroplane good you can even turn you just lean where you want it to go
One part of me thinks it wouldn't hydro, because while you are laying the front tracks down, water still has some time to get between them and on-top of them and quickly add a lot of drag to the back...but if it doesn't make it over them fully I think it would work, the under-chassis shape might even act like a lifting body.
It might need something that is equivalent to the front skis on the ski-doo that is a low friction gliding lifter to keep things angled up, else slowing down at all will possibly cause an immediate nose-down event and *bloop*
I love seeing the tracks act as reaction "Tracks" and correcting the vehicle mid-air!
this makes me think of old video game physics where you could slam into reverse mid air to change your pitch. i assume it's sort of a real thing?
@@ransomxvi well sort of, due to the law of conservation of angular momentum if the wheels stop mid-air, the whole vehicle will start spinning forward, albeit at much lower rpm due to mass difference between wheels and the body.
@@DiveTheseClips this is exaggerated if you pump it into reverse!
@@ransomxvi Yes! Stadium trucks also let go of the throttle mid-air to avoid landing on the rear wheels.
The same thing works on RC buggies. When you hit a jump, you can use throttle and brakes to control the pitch of the buggy in flight. Come off a jump and pin the throttle wide open, and the nose will lift and you'll land back wheels first. Do that on a jump that'll launch you fairly high, and you can get a full back flip in before landing. Lift off the throttle, or brake in the air and the nose will drop. When racing you modulate the throttle in the air to try and land as flat as possible. This lets the car settle onto all four wheels quickly on landing, and you can get power on and accelerate away earlier than say landing back wheels first and waiting for the nose to land before getting power on.
I'm really surprised about the amount of beating this thing could withhold
Especially since plastics tend to get brittle at low temperatures!
I would find it very interesting if you can add esc stabilization to minimize the pitch rate to prevent flipping it.
Hell yeah, have it maintain a perfect wheelie. (Trackie?)
Was thinking that'd be cool for RC cars. Set it up on a momentary switch of sorts. Guess we could try do it with a cheap Arduino and an IMU.
@@gem-squared What's interesting is that it could be set up automatically for any time it's in the air by just seeing when the IMU measures no acceleration (or below a threshold) which implies that it's falling, and therefore in the air.
interesting，if you are free falling, that would measure 0 G. I never thought of using that to determine being airborne. Perhaps adding rotational stabilization is necessary to keep it from flipping over
They have a anti wheelie system for drag racers who got tired of rebuilding the front end of their cars from slamming down all the time. I'm sure this dude could concoct it.
During the yard test portion of this video I saw a bunch of "normal" vehicles parked along the road and then there's just this one lifted Subaru Justy 4x4 converted from a station wagon to a pickup truck-like vehicle and I have a guess who that vehicle belongs to.
I still have an original one that I want to fix. It's going to cost but I think it will be worth it for myself.
hahaha yeah I spent the video thinking about that subaru
Impressed with those gears! 3d printed, hard on the throttle and stopping they kept on going.
The BMS doesn’t strictly need to be installed in the vehicle. You could have a multi-pin connector and an external BMS that is connected for charging only.
naw but discharge protection tho
@@fynnli6685 you’re right, but RC vehicles don’t normally have discharge protection. You can limit the ESC if you’re worried about overdischarge.
3:33 I spent about 30% of my life standing 50yds from that literal spot. Nice tech and cool vid!
Where is this? It reminds me of Whistler in Vancouver. I'm new to the channel
It's crazy how much air control those big heavy tracks can give it. Would love to see a huge drop to see it do a flip followed by stopping spinning in mid-air.
You have to design a modular snow cat with tracks than be swapped out for wheels in the summer for all year fun and maybe use torque vectoring to steer
Even just smaller tracks for the summer would make a difference
You should code something so when it's in the air it uses the tracks as reaction wheels to keep the vehicle level in the air. Could be a button u press while in the air.
5:33-5:36
what the hell typa noclip voodoo was that? snowcat's got skills
Those slowmo shots were absolutely FANTASTIC. Well done!
Nothing says “PNW” quite like an Outback Sport with half its roof missing.
So true.
Impreza?
@@CraigTaylor yes, it’s an Impreza, but in the US they called the hatchback version “Outback Sport” for a while.
That's the NoBack.
Love the filming at 3:30 with the tracked vehicle in the background. It's like a Tyco Fast Traxx RC car commercial
That Subaru-truck at 2:35 is awesome!
I’d love to see a snowcat based autonomous solar rover. Would be a good way to test durability.
You shoud add suspension . You could do it so the tracking weels/un powerd weels are in sets of 2 sharing damper.
Btw love your videos. :)
Uploaded 7 seconds ago!
Edit: You should get a spot welder, direct soldering really damages the internals of the battery. Just check internal resistance of one before and after direct soldering to see.
Not if you do it fast. That way the heat doesn't have enough time to spread.
@@blake_schwanke Well sure, thats why a spot welder works. Super high heat, very short duration. It can be difficult to get solder to stick to the contacts without heating the whole contact up first though.
@@jacobgold5845 Yes that is very true. However some folks like me are too cheap to get a spot welder ;)
I wonder how effective one of these would be with FPV for Search and Rescue. Maybe in weather where you can't fly a drone? You could cover a lot of ground with something like this.
Maintaining a datalink for control and video is the obvious challenge there. With typical RC hardware you can't go much beyond Line-of-Sight. Maybe if you set up relays on a couple of surrounding mountaintops to bounce signal between.
@@JosephHarner Red Bull (Dutch Drone Gods) just did it recently with drones on the Mountain bike urban downhill in Valparaiso Chile.
@@JosephHarner you can get 4g lte adapters on drones now...that connects to your phone or laptop and then to your remote software for your remote you are using for flying the drone giving you unlimited range...the only limit is the battery life.
2,5 kW is an impressive number. Electric Cars can drive 120 kph with multiple people with 10 times that. Or at the same speed with the same wattage probably.
Nice to see the tracks themselves hold up, makes me wonder if larger projects could be built using them
I'm honestly surprised that there are not any RC Snowcat tournaments. Definitely a fun way to spend winter!
Watching it lift off the ground during high acceleration made it look like you’d achieved a snowcat with ground effect all-in-one vehicle.
I really have been waiting so long to see a snowcat with insane speed like this
You might like the video of my custom “rc bashing tank” on my channel then. I design a 3d printed tank to go fast and jump! It’s not as beautiful as the snowcat, but it’s fast and strong.
Love the slo-mo shots with the life-size Snowcat in the background!
It's so cool how when you stop the tracks mid air, it tilts forward and you can kinda control the rotation!
Yo what is that beat up Ute at 02:33 ! I'd love to see some of that thing on your YT channel!
Also great to see that your lawn wasn't completely screwed by all the endurance testing, I wasn't sure it could recover after watching that vid
Looks like it could benefit from a little yaw stabilization?
Maybe some pitch angle based power limiting?
I wanna see more on the Subaru in the background at 2:36
Invest in a spotwelder, don't torture lithium ion cells with a regular soldering iron, it can seriously affect their performance and lifetime.
Cool mate. I love how you control the jumps landing with the tracks powering. Your shoots amazing.
I got lego 2s ripsaw. Its looks like 1/3 or 1/4 of the power of your 12s ripsaw.
Its the 1 or 2, strongest lego tank ever made with lego. Markpex got lovely one too.
I love the diy Subaru ute!
Had a buddy in high-school with a 4runner chopped the same way
Equally as jank build!
I love how it has enough torque to initiate a wheelie on flat ground! Sweet vid!
Awesome machine! I learned from running Battle-bots that they get WAY easier to drive if put the steering mixer on the 'bot and put a helicopter tail-rotor rate gyro in the steering channel. Made me a drift master :D Even tried it on some ice and it still gave amazing control.
Needs a 'Flip-Me-Over' lever on the top you can operate with a switch on the remote. Excellent little unit right here!!!
This build is so cool, and the fact that it's running on 12s now is crazy haha. I just built a twin 8s motor Armma infraction that I'm trying to break the RC speed world record with.
The only good thing Wargaming has ever done for anyone is to sponsor content like this
Cool stuff! Would love to see a sand performance!
Would be fun to watch you make a similar video to your autonomous tug boat pulling you around the harbor, but with this and a sled
you could add a distance sensor on the bottom at the front, so you could correct the throttle to avoid "wheelies", like a "tractioncontrol"
You could just make the BMS "plug & play". I didnt had space in my electric longboard so i had to plug the bms from the outside while charging. You could do the same and keep the upside down driving still possible.
Agreed. I don't think a BMS is really needed during use. There are lot of cheap battery alarms which will sound if the voltage of a single cell gets too low. One of these alarms would be smaller than a BMS.
man this channel just makes me so happy
This is a testament to the durability of the tracks. I can't wait to get my kit!
In the video where you drove the RC snowcat around the actual ones I could only think of the audio of ‘You’re doing great Dad’
excited for possible future flip-over-able 12s rugged electronics unstoppable cat action, cheers dannymane
I didn't think you could do wheelies with a tracked vehicle, but here we are.
maybe to prevent as mush bouncing round well on bumpy areas maybe add suspension to the top and bottom on the snowcat
Nice work on the 12S snow cat. I might suggest a stretch to the chassis to allow for the battery protection. It also might make it a little easier to drive.
I’d like to see a high powered version of the terrain twister. One of my favorite RC’s I had when I was growing up
that slow motion was cool AF!
Thanks for reminding me how much I can't wait till next season
Can’t wait to see more waypoint mission projects
i think extending this by only enough for a extra wheel and using tracks that are more studed than paddle and a bit more narrow would be super interesting cuz atleast in theory thats stop the back flipping and allow you to more reasonably control the vehical and even maybe, drift
i love souunds of motors when you rev up
Bringing back some of my favorite 90s memories. Tyco Fast Traxx!
I’m in love with the snow cat, what if you folded the design over and made it one track with a U shape from one side to provide a platform which a skateboard deck could be mounted to a stretched out version of this. Then put some foot straps on the skateboard. It’d be the coolest sorta electric mountainboard ever. Even more tricky and cool would be to sand proof it so it could be a sand skimmer / snowmobile - board
Or a tank track electric skatevoard
the orange section in the tracks makes it perfect for slow motion
Autonomous solar snowcat when. Long range South Pole solar snowcat mission when.
That's really cool. It would be nice to be able to go upside down. You'd be unstoppable!
I’ve always wanted something like this that was attached to my snowboard for when the terrain is flat!
Hell yeah! Since you like high voltage stuff, you should get into electric skateboards. I'm in the PNW also , I'm trying to make an electric skateboard using your tracks!
Ripper cat seemed pretty fun. With a good bit of nose weight, it could probably be setup for high-marking.
This would be a hella cool base to build a RC Tank on
At this point I won't be surprised if he adds suspension.
Keep up the great work!
Battery nerd here with some friendly advice:
I like the frames you made to hold the cells, and I like the space you put between each cell... however I'm not a fan of soldeing to cells. Soldering to cells vs tab welding can damage the cell. That's not to say you can't get away with it, but it's not great practice. We put so much effort into our 3D printers, gearing, and motors, we should put the same effort into the battery. There are cheap tab welders out there that do better work than overheating a cell with a big blobby blob of solder.
I like that you have a BMS for charging and balancing. Ideally all power would flow through a properly designed BMS, but I understand why you pull the discharge from the raw cells even if I wouldn't do it that way.
If your motor controller has an under voltage cut off (UVLO) you should set that to no lower than 2.8V per cell. If you are not using any discharge cutoff you should also make sure to unplug the cells from the motor controller when done for the day as the quiescent of the controller will slowly draw the cells to Zero volts and kill the cells (they often fail shorted as the chemistry eats itself.)
You should also put a slow-blow fuse between the cells and the motor controller. It should be inside the "pack" in such a way that you can't bypass it. It can be rated quite high, (1.5X or 2X your max current) but it should be there to stop the insane short circuit currents these packs produce. This prevents small shorts from becoming self sustaining plasma arcs.
Oh, and never ship a home made battery pack anywhere ever.
Nice trackie moves (track vehicle wheelies). Wonder if could use a drone gyro to limit maximum pitch-up angle, so could do prolonged trackie runs? Such an option (combined with a foam belly pan) might allow crossing small stretches of open water. A trackie day at the beach. ;)
Regarding cell balance and protection, you could save a bit of weight by wiring in a balance lead, and only connecting the balance and overcharge protection when charging.
Looks like you drag-racing snow cat needs a spoiler to keep the nose down. But this video was so much fun.
That looked like fun, could you add some sort of flipper to tip it over again when it ends upside down?
A suspension might help part last longer that does not handle impact such the battles longevity from jumps and drops. But, looks cool.
Wow! Amazing video!!👍👍👍
I have an idea for this Winter and this build. What if you use Mission Planner to write or draw something in the snow. Then people can see messages printed in the snow. It could be used by ski resorts to print something on the slopes. Who knows maybe a laser could add details.
If you extended the body of the snowcat just an inch or so behind the back tracks you could eliminate the tendency to flip over, like a wheelie bar on a drag racer. As the whole vehicle tilts up, the tail end of the body would slide on the snow and help maintain a wheelie.
Another thought: run a curved bar over the top, so when it does land upside down it wants to roll back upright, or at least to the side so one of the tracks touches the ground and the tank can spin back back upright. Right now it is highly stable when upside down, so anything to disrupt that can help.
Snoqualmie pass has snow in may??? Great project dude!
I think 2 of these mounted to the bottom of a snowboard would be very interesting!
How to obliterate your knees in 3 easy steps. Would probably be fun as hell though yeah
Always a good day when RCTestflight uploads....
Yeah, especially when on that same day Think Flight uploads as well! Love the content coming out from both of you guys. And what an awesome collab on the ecranoplan!
Impressive for Christmas 🎅
One great visual feature (which has been there since the early prototypes) is the contrasting colour segments of the tracks. Makes it look dynamic any time it is moving. How about three colour tracks, RGB?
Im totally getting one at about v5 lol. Super 10/10 awesome work and style! Mucho enjoyo
lawn has grown back well
Thanks!
I was going to say remove the BMS using some connectors so it's "flippable". But I actually think you should add a lever which can flip it back over in the case of overturn. Even if it takes 30 seconds, it's better than hiking to the machine.
Impressive. Gone are the days when we'd see "RC Testflight" written on the body in Sharpie ink. Now it's engraved direct on the top panel. I'm trying to think like Daniel here, so consider this... Since the latest mod won't allow the cat to run inverted, a long hinged arm on a servo needs to be added to the top. Then, whenever it flops on it's back, a flip of a switch on the radio deploys the arm from it's lay-flat stowed position to umm... "fully erect," so it flips the body over and off it goes again.
I had fun watching!
3:30 Nice shots！！
Aww I wanted to see how it handled a steep incline climb
That’s amazing with all that power!
It would be soo cool if you could control the pitch during the "flight" by changing the speed of the tracks so it would always land completely flat.
Really cool. A bit conserved about soldering and not spot velding the batteries at 1:50.
You'll now be able to catch up with the big snow thingies
Sick! make the next version able to ride upside down also, would nail it :)
Your first test drive footage is kind of what I envision how the testing of the USS Defiant from DS9 went... "Put simply. It's over gunned and over powered for a ship its size. When they tested the engines at 100% it nearly tore itself apart."
very cool build!
this for filming slalom skiing fpv, ugh would be so amazing
Jesus how much suffering do this gears experience :D
man the fact that it tanked that fall is a really big testimet to your design
You should put a servo in the top part to make it rotate when you flip over to get back on track
Awe thought it would be
RAAAIIIIIIDDDDDDD
Also thinking the batteries could be hot-swappable looks like they're soldered in place
5:40 whoa that's neat it's able to re-orient itself in the air like a reaction wheel ha
6:54 wires look thin
it needs a trailing ski on the back, kinda like how drag cars have one in the back to limit the wheely
Never thought you would need a wheelie bar on a tank ! Lol 😆 that things rips!
Just call it a trench crossing tail like on WW1 tanks
