Nice tips. What website sells for carbon sleeve and epoxy resin?

hi,

no there is no alarm ... might it be connected to the brand of the transmitter?

the legs would go up, doesn´t matter if i power up the transmitter first or reciever.

... but i also figured out, that if you loose connection to the reciever the legs go imediatly down - important for failsafe!

edit: i am stupid - i was setting this up in the transmitter with V1 ...

Aaalie thanks for sharing.
+1 waiting to see your next vids...

For us in America, I found this link:
http://www.fibreglast.com/product/Br...ow-and-sleeves

How many yards would be required for the 6 arms?

Regards

Roberto

WOW that was sad, all the way around! Imagine if he hit someone in the face...

As I stated before "not that this pertains to this event" Not all pilots poses the same skill set, and I believe unless you can fly YOUR Multi or Heli in FULL Manual Mode, you should not be allowed to fly close to people or property.

It sure looked to me the guy could have just cut the power while passing over the Field and let it smash the ground. instead of what happened..

I train pilots for a living now, and can tell you one our first lessons in flight is know your limits, know the limits of your equipment, and before each flight is carried out have a flight safety brief with your crew. Always be looking for a Ditch Point.

As we begin to train professionals, they learn how to do a risk analysts/assessment, how much is the shoot worth, how much risk is involved, can my equipment carryout this task we placed upon it, leave your ego at home, the minute you power up over persons you have now placed them at risk.

Not the smartest flying I have seen, the guys involved here just blew it all to hell...hope no one was hurt.

In closing People, use your head, safety is no accident!

This tops the cake in the Fail Department...

Thanks for the source for where to buy the sleeve. So, you think 1.5" is okay for an S800? I have tried the CF tubes beneath the arms and also filled the first 10 voids of each arm near the hub with J&B weld so they are pretty darn stiff but there is still just a little twist that my setup will not eliminate all together. Can you tell me what the best, lightest solution would be to impregnating the CF sleeves? I know there has been mention of a variety of ways of doing this but are there any final conclusions on the best product? Names, sources? I am going to give this a try because I am still not satisfied with this S800 and these flimsy arms despite my best efforts to stiffen them.

Thanks to both of you. For some reason I was thinking you put the sleeve on the arm and then coat it with resin. I was thinking I would make a big mess out of that. After watching the video, the only question I had was what size to get and heli001 answered that for me. Heli001, do you get your resin from them? If so, which kind? I also don't want to buy a huge quantity that I will never use.

Thanks,
Michael

This is what we used, cost was 71 dollars, plus shipping. and the Heat shrink tubing.


Sleeve https://www.acpsales.com/Carbon-Fibe...d-Sleeves.html
Mixing Kit https://www.acpsales.com/Epoxy-Resin-Mixing-Kit.html
12oz Resin https://www.acpsales.com/EZ-Lam-Epoxy.html

Remove your arms, prep by thoroughly cleaning the arms with 90% Isopropyl Alcohol, lightly scuff the outside arms with 220 grit, clean again. set aside.

Tape the motors and end sockets, cut the carbon braid to length, cut the heat shrink to over lap the carbon 1/2 inch or what ever you choose. just remember it will shrink and expose the carbon, so longer is better

Mix the resin, presoaking the carbon might help in making the resin even, carefully slide the carbon sleeve over the arm and while holding it in place slide the heat shrink over it. When you are happy with the placement, heat the shrink tubing till it conforms to the arms shape.

Thats it, you could do it different, and also apply the resign after you slide the sleeve over the arm, or even add more resin to the cloth after its in place. Just make sure you apply enough to achieve a full saturation.

Also after the fact we learned you could also add to carbon strips on either side of the arm aprox 1/4", gluing them in place first, then sleeve the arm, this might even give better results.

And you could mix resin and kitty hair fiber glass and fill some of the voids pryor to sleeving them.

As far as the Heat Shrink, you can leave it on, as its a minimal weight, and allows the user to not worry about achieving a perfect outer finish. or after its dried, remove the heat shrink, sand lightly with 220/400 grt and apply a finish coat of resin.

Thats my take on the mod.

Right on!

Sounds like most are in the same mind set...

I will say now with the mod done, it is a night and day difference with stability, vibrations levels are close to that of a rigid frame, and our video is much better, now we are doing dennys prop adaptors

Thanks! That's exactly the resin and mixing kit I was just now looking at. I have a couple of arms that I broke that I could experiment with as well. I think I'm going to give it a shot. I will probably just leave the heatshrink on since I'm lazy.
