Awesome video man! Still waiting to get ahold of the commercial version of your 4” long-range. Sold out everywhere! Congrats on the awesome design, and it's success!
Dave this was fantastic and would love to see more tutorials in Fusion. Can we see a tutorial on canopy design please?! Oh and where is that PDF?! 🤘🏻🤘🏻
Hey. Great tutorial. Gave me everything I needed to start my design. And also please could you share the cam model so I can make sure to design the frame right around it. I don't have a nano cam to get the calipers on to yet. It's hard trying to guess and I dont want to get it wrong. Many thanks keep up the great work.
Lotsa good info and techniques for us Fusion beginners. I watched it twice! I got a little lost when you started manipulating forms on your canopy video. Any chance of expanding on the use of forms in a future vid? Thanks a lot man!
interesting, i do it from the inside to the outside so i don't have to constrain myself to a specific diagonal i have a timelapse of a frame design on my channel
Btw, for the weight estimation. You can define the physical material to CFRP (plastic) and directly get something quite accurate. Weirdly fusion don’t have CF materials 🤷🏻♂️
cfrp means carbon fiber reinforced plasic, which is exactly what cf is, too the carbon fibers are encased is resin, which is just a special sort of plastic
So you do absolutely give carbon cutters a headache I would suggest explaining the common size radii, and the smallest, that can actuall be cut with a cnc router: 1mm, 2mm, 3mm, 4mm diameters are common. That being said having a design that will need multiple radii end mill bits will cost more. Also quasi-isotropic refers to how the weave in conjunction to the layup patterns (how the thin layers of carbon are stacked during production). Just because the top surface layer is oriented one way doesnt mean the majority of the layers are oriented that way.
Wouldn't they just cut the whole thing with a 1mm radius tool? We are talking about pretty small parts here. I never said you can always draw conclusions from the cosmetic top layer about the layers underneath! But the CFK commonly used in this hobby happens to have layers with a 90degree orientation relative to each other so it's still important to design in a way that in principle allows a proper orientation of the parts
@@DaveCFPV 1mm is small and there are good rules of thumb in machining not to mill too deep too fast with a small bit. So if you can increase the radius you can decrease the machining time and since most cnc carbon cutters charge mill time - you save money. And regarding carbon is it really tough to tell. I have a studied carbon fiber and advanced materials for a while now and carbon sheets are tunable and unless you know where your carbon sheet distributer sources their carbon and can track down layup diagrams it is a crap shoot on your orientation of you plies. It is not that hard to mark carbon sheet flat ( you just mirror the layup pattern across the midline).
@@ian4447Short answer is because while aluminum is isotropic (same material characteristics everywhere in the material), composite materials including carbon fiber are anisotropic (differring material characteristics in areas in the material). As a result if the anisotropic material characteristics when the ductile material (usually a 2 prt epoxy) is added it needs to be cured in an autoclave under heat and pressure. Curing the epoxy and carbon fiber composite can cause those anisotropic stresses and strains to display unevenly which causes the composite material to warp. In order to distribute the stresses and strains better and improve direction operational performance the plies are rotated every layer or several layers and then mirrored over the mid plane - which for 1mm thick carbon sheet would be at 0.5mm, hence midplane. It would help if you looked up a video of carbon fiber layup process or google quasi-isotropic carbon fiber layup pattern it will help you.
@@zachcarrizales5038 You are assuming we use quasi-isotropic CF for quad frames. If it's not quasi-isotropic then the orientation on the outer layer is also what's inside.
You need more of these. I have a few crazy 4" designs in my head that i want to get sketched out in 3d
a video with a 3d style frame like your longrange dead cat would be very helpful since that is a unique shape

AWESOME man, i have been looking for such a tutorial for LOOOOOONG time. Thank you so much for such post.

Are you going to do another one of these? maybe a multi piece frame? Super helpful stuff.
Yes I will do more tutorial probably in June or July
Great videos session
Where is the pdf sheet?
Thanks!
pdf: bit.ly/35ncqsb
Thanks!! Very useful :)
Will you share your pdf too?
Thank you!
Finally someone making a good Tutorial about Frame designing ! Thanks Dave
Great video mate once again and thanks for the shoutout.
I will definently learn how to use Fusion360. Thanks for tutorial.
Your Mircoblivion is great frame. I like it a lot. Thanks.

Oh Thanks ! Good to know ... Seems like CF varies quite a lot. Maybe that's what they didn't include it
Dave_C FPV you’re perfectly right on that. Depends on cf type, quality, etc
cfrp means carbon fiber reinforced plasic, which is exactly what cf is, too
the carbon fibers are encased is resin, which is just a special sort of plastic
Btw why you don’t use construction lines it will be more helpful when selecting areas
Good point! Not sure if there a shortcut for them tho
@@DaveCFPV x is the shortcut
And now onto FEA!
Thank you! So many good tips here. I've been doing this so wrong haha
Haha thanks! I don't think there really is a right way. Just trying to show how I personally approach it
Pretty interesting, dude!!! 😃
This is a great channel!!
PDF for the right references :P ? link
