Fully 3D Printed TANK - Brushless Gear Drive 

Did you know there's a ratio of track size to body size that is optimum for tanks? You may want to do some research to optimise your build. 👍

Thank you so much for just being no nonsense, simple and straightforward. I've been watching you for many years now, and you haven't changed. You produce great stuff, share it and just do what you like. Stay who you are please and keep making these wonderful videos.

The Tupperware saga continues... Also,we need googly eyes

If you can ride a 200% version I might make one.

That was neat! Here’s an idea: I realized when you showed the aerial view, you could’ve drawn a picture (or write something) in the snow. Either use the tracks to make the design or have some sort of colored water sprayer to make a large dot matrix print. Your videos have been inspiring my students...thank you.

Take a look at herringbone gears, they're harder to design, but provide much smoother and reliable action.

Someone let Ivan Miranda know you can build a 3d printed tank without spacers.

Amazing amount of energy and work you put into designs, builds, and videos! Keep up the good work.

7:50 that's a cool sequence

Tpu tracks perhaps for more "grip" ? That or perhaps texture/angled sharpening/spikes etc?

Beyond impressive. You always seem to think outside the square, and the creativity of your design process is admirable.

Awesome! Really like those long endurance missions you put on your creations. This and the atuonomous boat have to be my favourite. Keep it up!

Very cool. I'm never going to be able to build something like this (I don't have a 3D printer), but watching you show what is possible to do with a 3D printer is amazing. Looking forward to seeing what else you have in store for us, to keep us sane in these crazy times!

Great stuff Daniel. Loved the hyper zoom-lapse drone footage during the ‘field’ testing.

Your videos are GOLD. I can’t get enough of that dry humor, and to top it off, the projects are always so innovative. Thanks!

Hey thanks for taking the time to share this! It's always frustrating to see designs not get past their 5 iterations. You don't do that! Problem solving is part of your mo. Good job man!

Always great to see a new rctestflight, Keep up the good work !

That gearbox is very impressive! I am super impressed that it held up to all that use. That failure in the muddy field is called throwing track. A twig or something got caught in between the wheels and the track and pried it off. The reason for *that* was not enough track tension. You could increase track tension by adding an idler wheel somewhere in the design, or make the wheel on the opposite end of the drive sprocket into an idler wheel. Warning: properly tensioned track will stretch out over time. This happens until it is loose enough that you start throwing track again. So if you have an adjustable track tensioner you need to keep tabs on it. Also, longer center guides on your wheels can help you recover from situations that might cause the track to come off. Nice work!

You’re a damn genius, this thing looks amazing

I recommend looking into nylon filament for making super durable gears. It's a pain to print but is the definitely the most durable 3d filament.

Seriously cool. Your engineering skills and ambition are impressive as always.

Really cool! I am in the process of making a 3d printed rc Tank so its cool to see other people doing it.

Man, thats amazing! Thx for sharing the stls!

What I find the most impressive is the accuracy you managed to get with your gear meshing distances and what not. Since it is 3D printed and you had to “help” the fitting of the rods and axles and still managed to get what I would consider a perfect mesh.

It would be nice to see more of the CADing/design process. Great video! Very nice tank.

for the gaerbox: lower rpm->more torque->larger gears, the warnout of gears is proportional to the pressure of conatact, less levage equals more pressure

Yet another cool Video by rctestflight. Thanks for the entertainment throughout the years

You have my heart every time I see a new video of yours that comes across my suggested I'm Blown Away

The narration during the montages had me in stitches! Great video!

Been super excited to see the result of this! Awesome work

Boy, tanks are in!?! Awesome stuff Daniel. Arbor press.....not necessary.....but certainly more fun😎

Tank ski’s next up. Good job. And that time with the vids must of taken ages. It works really well Daniel 👌

Hi rctestflight, love how the tank turned out, I had an idea for your concrete traction problem. And it would help overall too. On your treds you should glue or rivvet little rubber flaps on the edge that touches the ground almost like paddles?... it would dig into the snow and also the rubber would grip on tarmac, you could make these easily with only Bicycle inner tube rubber, cut strips and one by one add them to the end of the track sections. Hope this helps and happy adventures

Absolutely amazing!! Great tank, great design, amazing video

Another very cool project :-) Looking forward to the next video :-)

I found your channel tonight, and was browsing your older videos... solar plane V4 was awesome! Then I went back to your channel and had seen you uploaded this 4 minutes ago... the timing :D

The wonders of 3D printing, ingenious engineering! Keep the good work up!

Your shop is amazing!!!! Damn son! great video, great build, seemingly awesome skills. Great job!

Thank you for doing things that i would like doing unless life was in the way.. And thank you for making great quality videos.

Very impressive Daniel. Look forward to the next tank video.

That is awesome! - Nice work - We will be building / printing one of these soon!

Congrats! Great project!

Awesome video and sure usefull information on printed gearboxes. Great work !

Love those dramatic aerial shots.

After seeing this video you motivated and inspired me to finally get a video done of my 3D printed rover tank that I made. Thanks :)

How neat is that! You can tell it’s a 3D printer by the way it is.

Great job love seeing all your projects. I remember an old kyosho car video that suggested using toothpaste to run in the gearbox to remove the burrs on the gears then switch to grease. Also I've had good luck with the gear generator in inventor, I generated and printed 40:1 worm gears and printed in pla

That's a really simple desing and at first i though: That seems a little easy... But it looks like it works great and even better than some of the overengineered designs i've seen here on youtube! Great Job!

Awesome job man, Round of applause 👏 👏

This is cool as hell Daniel!

Great job as always. I love your creativity.

Now that's a nice project thanks for sharing 👍👍👍

Very nice design. You chose a good material for the gears for PLA has high resistance to abrasion wear. The only disadvantage is slow biodegrade with water over time (years), but the #1 for you would be that PLA gets more brittle with UV from the sun. I paint or at least clear coat my outdoor projects in UV resistant paint which doubles as waterproofing as well. You have some clever features: the nested gear layout, heat dissipation fins that double as cool factor, Good track width /support ratio, Large front driver wheels, and #1 is it's simplicity. As for PLA gear lube, I've used white lithium grease in production gears. It's friendly with PLA, and the tiny little layer grooves made by FPM machines such as yours hold the grease well like an impregnated industrial plastic. Very little is required. Very Nice! I look forward to your next video. -Boone Brandenburger

You could make a spot on front could put a mop handle into and have it push you along on the skis using your hand to provide down force, there is some commercial motorized ski thing that does it for cross country or going up shallow hills. Handle would stick out front at like 45 or 60 degree angle so pushes you forward and you can provide down force or in the commercial version it attaches to a belt.

i love seeing printed parts, especially pla, stressed like this. so awesome.

Epic filming mate! Well done!

Great project, The gearbox did really well!.

“Ah yeah look at that torque” hahaha amazing

i just watched few of your videos, im totally impressed by your creativity and skills. So young ! i would not be surprised if Hollywood hire you. i really loved your video in the desert with the bike rider, and 16mm video on Kodak 50T. Cheers from France

Nice work mate !!!

You could look into a coating for your tracks like a bed-liner coating or Flex Seal. Maybe only coat the ground interfacing sections of the tracks?

Besides the cool content, your video making techniques, abilities and skills are great!

Yours is the only channel I consistently or should I say ever hit the like button on.

Awesome, love the design.

For some reason functional gears have been my favorite thing to print. I am curious as well to see how the PLA holds up.

What an excellent engineer. Well done!

I'm pretty sure it'd be able to climb vertically if traction was no issue. Unless you're planning on a lot of cargo, you might want to make your gear ratio such that the force at the radius of the driven wheel is less than tank's weight. More battery or more speed!

The track repetition in the snow is really cool to see it's consistency.

That tank is awesome dude, you are a genius!

Amazing work👍

The level of excitement here is top notch, how neat is that

This is the creativity I subscribed for in full action.

the random track color is cool. i know you did it because it was whatever color you had, but its still jolly. Looks like tracks made of old scarves

Great job!!!!! Very Clever!!!! Bravo!!!!

Idea if you feel ambiguous. Some may think it's dumb but felx-seal has a rubbery texture to it and if you take off the you don't want felx-seal on you could spay or brush or roll it on to the trad for more grip!!!

This video was extra sarcastic. I love it. I'm curious to see where this little tank goes next

I would have really liked to see you put one of those lower-ratio gearboxes in there and have it go crazy fast

I found that using TPU for the tracks really helped out with the traction. You might also try nylon for the gears.

This is amazing... You'll probably be the reason I will get back to modelling at some point... This time to software-controlled thingies

Nice build! PLA pretty durable. I ran pla caterpillars, joints were even pla instead of wire, and they lasted about 30 half hour runs on my TinyTrak tank...they never snapped just stretched...

That was simply flipping awesome!

really really nice project 👍🏻

Great video, great thumbnail. Subscribed

very cool, I'd consider making a hollow groove in the tracks and fill those with a rubber shape cut to fit.

Love this build

that's quality stuff. Keep on doin GJ!

Realy good design work.

Your videos are incredible keep up the great work

Definitely my favourite thing you've made.

Nice vid. I'd love to see how tracks printed from TPU would turn out

Tanks for releasing the files for free

Rover: "What is my purpose?" You drive in circles

I have been following you since the beginning and you amaze me, the bible tells us to treat younger men or women as sons or daughters, older as fathers or mothers and the same age as brothers or sisters and son you really have it going and it pleases me to no end to watch your videos and marvel at your ingenuity and I thank you for all you do.

Kool camera patrol tank? Lol that was an awesome run time.

This man makes everything big

That is awesome! You should build an autonomous lawnmower to run the waypoints first, get rid of those thorn bushes!

Would love to see how it would fair if the tracks were made out of TPU instead of PLA. It's abrasion & chemical resistant, and depending upon the brand/shore rating, that extra little bit of flex for the grooves would probably help it bite/grip surfaces you experienced issues with even better. Looking forward to what else you have in store! Keep up the great work!

Proof you don’t need top quality prints to make a great working and functional machine! Love it

This was an awesome video!

surely you have a soccer field in the area. You know, I nice level, even and spacious area to put your awesome creation through its endurance test without external influences.
