I like it when you turn around real quick and look at the camera every time you crash, as if to check and see if we're still watching. Also those signature quotes, "I know I look like a PRO, but don't be dis-encouraged, if you can't crash like this, it take years of training" "A taste of impact strength" "Our chances are slim, hmm non existent". Thanks for the chuckles.

[@simat565]

1:39 "it's also painted orange, so it fly faster"... yes that make sense 😂

[@CHRISGr33r]

I use 0.065" weedwacker trimmer line for my source of cheap bulk Nylon filament. For Nylon I also recommend "rehydrating" the nylon, since printing evaporates the moisture in the filament. After a print I submerge my prints in hot tap water for about an hour. This should solve your issue with brittle nylon. Dry it off, and use. Great idea. I might try it myself.

[@Henchman1977]

Have you tried not running the drone into stuff?

Hey! You came through on this endeavor! I get that it took a loon while with all those prints and testing them all one by one. But the more respect for carrying through on it. And what a result. Don´t you think it is time that you put an affiliate link for that filament in the description? I mean you deserved it if anyone does deserve to make a few pennies from that.

use truss structures in the gap of the arms of the drone frame. The Truss structure may help in distributing the impact when crashed to any obstacle.

[@ryanlarson5565]

Awesome video! Longtime watcher, first time commenter here. Polypropylene is an awesome material for flexible applications, but the other huge part of designing something that is flexible in the right ways and rigid where necessary is the geometry. If you know how the frame is most likely going to be loaded during a crash, then you can adjust the geometry and get all the behavior you're looking for, even with materials that might not seem flexible at first. There are examples of metal devices that are designed to be flexible. Some great resources are the video "Machines That Bend Are Better" by Veritasium and the books "Compliant Mechanisms" and "Handbook of Compliant Mechanisms" by Howell. I'm currently taking a university course from Howell and it's really good stuff. Edit: Apparently I haven't watched quite enough of your videos, because I just got recommended your 3D printed compliant vectoring mechanism video. So you're definitely aware of the resources I mentioned. *Facepalm*

[@maglev_]

What fpv monitor do you use

[@narpat007]

Thanks for providing such a vital information based on your own various tests and trials. So PP material is best for quadcopter frames ! thats awesome !

[@DomanStuff2022]

"Small PP", made my day dude XD

[@mannythehunter]

Neat to see it work in the end. Halfway through your video you got me thinking maybe adding "breakaways" spots on the arms that are made to pop loose when you impact something. Having a joint on the arm that pops loose on impact using that motion to absorb/use the energy of the impact.

[@EnergySeeker]

very nice , can you share the STL and setting , and where did you get the kit for the drawn?

[@markrutte66]

Simon, i think if you use a dual extruder, one with flexible filament and one with petg or pla, and lay the print down switching between layers like: flex pla flex pla flex pla you get both of best worlds. just like bones work. (collagen is flexible and lime is rigid)

[@safetyinstructor]

You gotta stop flexing man...

[@bobhawkey3783]

Come to Saskatchewan, Canada. We have few trees, just cattle and they're soft. Love your videos. Such great humour. For a Swede.

[@4DCResinSmoker]

The ground / grass gives some, which is why the impacts are less damaging. The tree on the other hand, isn't going to give much. Hence why you have a broken frame. Furthermore, the smaller the quad the more likely it is to survive a crash due to the square-cubed law.

[@BlitzaceLL]

I really liked the TPU aproach. I would probably explore that a little more. My idea would be to print the TPU frame but with slots along the arms and then print PLA (because its cheap) or a more rigid filament "flat sticks" to insert in those slots to make it rigid. If it hit something, the PLA would break but the TPU wouldn't, then just insert a new PLA stick and good to go! Print a couple of them and you would be flying for a long time I would say. Still a very cool video as usual and loved that fall at 6:00 xD.

[@Dangineering]

had the same idea! Have you given it a try yet?

[@BlitzaceLL]

@@Dangineering I have not, unfortunately as I don't own any drones atm. If you give it a try let me know if it worked!

@@BlitzaceLL I plan doing this is within the next couple months. I will let you know how it goes or just make video once I have the final design.

[@CupolaDaze]

The camera work and film making in this video was on another level compared to other videos of yours. The pace was great the little throw one drone into another and it magically comes together was a nice touch. Really nice work!

[@homan1]

Dina videos är bland dom bästa jag har sett på KZbin!

[@arawinters304]

Try OBC, it's by DOW. I've been switching some of drone part prints from TPU to that when I need stiffness but able to take a hit. I haven't gotten my slicer settings totally dialed in for it but the material properties are perfect for drones. plus, 30% less mass density. It needs packaging tape or magigoo-pp for bed adhesion.

[@domowysurvival]

The composite idea (using two different filaments) was pretty good, I think, maybe you should try to make some kind of inserts from one material to the frame made of another material. Like carbon fiber rod in a fixed wing of an airplane. You could even introduce steel rods to the drone's arms by melting the plastic a bit and just putting it, like a stick in a wet concrete.

[@edfroxt7294]

I experimenting with elastan d70 now. Very strong material, also have a little flexing. On my ender 3 prints very well

[@Dr_MF]

Your friend is great .. he crashes with no trees at all wow

[@ShaunCullen]

One idea I have is use carbon fiber tubing along with a central rigid piece where the tubes all meet. Then have a the outer part of the frame be full TPU where the carbon fiber can slot into, just under the motors. The carbon fiber should give it enough rigidity and the TPU is indestructible. Glad the PP worked for you tho! I wonder if a different type of Nylon would work, or maybe Armadillo from ninjaflex, its their most rigid filament. Love your videos, keep up the sarcastic and fun style!

[@nickg6312]

metal frame but in segments like body and 4 arms all separated but connected with cheap plastic pieces. so when it crashed it breaks the plastic, not the metal frame. bring replacement plastic connectors (3d printed) after each crash replace the bad ones (make it modular)

[@magneticanimalism7419]

With a little practice I think you could pull off a half decent Christopher Walken impersonation. Thank you Simon for the awesome entertainment value and the 3D printing tips. You're doing it right by my books.

[@laytonblance]

I’m impressed with your line of sight flying, very nice!

[@CJ_Bones]

Try having sacrificial arms that will absorb the energy of the impact but are very easy/cheap to replace. This way you come stocked with just this replacement part and don't need to remove the entire rig from one body to another one.

[@H3zzard]

Spicy impact experiments with trees. Nice! An external frame for the electronics and props made of flexible material might cushion any misadventures... but might add weight.

[@madladdan]

You should put holes in the tpu frame so you can put carbon fiber rods down the centre of the arms instead of pla on the outside. The rods will snap on impact and take the stress off the rest of the drone.

[@hugocatbro13]

As an FPV pilot this is absolutely hilarious, and I don't even know if that is an insult

You gotta add fillets to those corners. Those sharp corners result in high stress concentration, causing it to break in light impact

[@BurtMeister]

You could probably make TPU/PLA work by printing one inside the other with a dual nozzle/extruder. I suppose it might make more sense to have the TPU on the outside for shock absorption and have PLA or similar used as the structural bones for rigidity and strength? I guess you could go even further and have rigid exoskeleton of PLA/PETG as an addtional shield, but this might be adding excessive weight to your quad.

[@kevintrumpf4156]

after printing u need to put the parts in the oven at 150-170 celsius for 30- 60 minutes that process helps to inforce the structure
