F75 Pro Max Knot© Tutorial

In some builds with some ducts, the frame could benefit from some added stiffness.
One way I've found to do that in a lightweight and durable way is by tying a thin nylon fishing line around the side ducts.
This tutorial video shows you how to.
Apologizes for the vertical format; I had planned to make it a short, but found out editing it down to 1min would have compromised the explaination
If you're having tune issues please try it out and report back!

Great vid Yves! 👍 I need to get some fishing line.

[@8BiT_fpv]

heck yea cool idea man, i could probably use dental floss in place of fishing line?

[@fractalengineering]

I guess you could try! Don't see much reasons why it would't work

[@fokusfpv]

what do you think about using a solder iron and melting them together - similar to what we do with the printed carbon fiber ducts to connect the struts and ducts?

[@TyranttFPV]

Do you find that you break ducts or bend props less with this knot?

[@fractalengineering]

I am yet to break a single duct, motor or even prop with that build, with or without the knot 😅

[@djs134]

Hard to tell in the video but are u basically making a knot on each side of the duct strut ?

[@fractalengineering]

no; one knot on top after the first loops, then double knot after the tensioning loop, again on top
