I'm wondering if any of the companies that are currently producing FBL blades are going to put out some nice rigid 3D FBL blades in the 800mm size range(for a decent price too). The Logo 700 is supposed to accept 800's right out of the box, and my Ion X2 could take them with the edition of a longer tail boom and tail drive shaft. I for one would love to try 3D with an 800 size machine!

Check out the video of the new Shape 8.00. This is with NHP 800mm.

Very cool indeed, what a monster! The NHP's are not FBL though are they? Also, 800mm blades tend to be in the $300 range don't they? I'm hoping if they become popular enough, they will come way down in price.

v v v Yeah, they do look and sound good.

I don't believe he NHP's were specifically designed for FBL but judging from the video they work pretty well.

just as a comparison:

I had the 710 NHPs on my 3DNT flybarred and they were fine. converted to vbar and it still flew fine, but i couldnt get the cyclic response i was after.

i tried on a pair of radix 710 non-SB and it was a whole new machine. now, i understand the non-SB are not specifically FBL blades. But, they are what many used before FBL specific were available.

So, I'd have to think the addition of some proper FBL blades to that shape would be amazing.

if it ain't broke, break it.

If I'm not mistaken, there are some FBL 800mm blades being developed and tested...

Brand?
Would you mind mentioning which brand, so we can encourage them that there is a good market place for them.

I've been given the go ahead, EDGE Rotorblades sent me 3 sets of blades to test, 813mm, symmetrical, 14mm root, 5mm bolt hole, can be bushed to 4mm.

I tested them on both a Flybarred head and FBL head, that would be FBL NOE of course...

More details to follow, with some videos of testing...

Cool, I had already heard that Edge were working on 800mm blades, but I didn't know they had prototypes out yet. So how do they feel?

The 3 sets were all of different weights, so each set felt different in how they flew, both flybarred and FBL.

The set that I picked as my favorite flew GREAT, in both modes, and on one of our heavier cameraships, carrying a payload.

VERY Smooth, tracked beautifully, stable hover, at HS up to 1650.

3D flying on the FBL head, again at HS up to 1650, gave VERY predictable movements, great cyclic action, powerful collective (lots of "pop", but you'd expect that with this size rotor disc and only 11-12 lbs of helicopter under it.

NO idea of cost yet, I'm sure they'll announce it on their website when they're ready.

That vid of the Shape fying sounded like 2000 HS. Is 1650 about as high as you fly, generally Chris?

And are the 813's going to be good to 2000?

I did not test them at that high of a HS (2000), so I cannot definitively say. The heli I tested them on was setup, gearing wise, for a max of 1650.

I WOULD suggest that it is MORE up to the rotorhead, or, IOW, that I would ensure that the rotorhead is up to spinning the blades at that RPM.

We have spun V-Blades 810's up to higher RPM's, at similar weights as these EDGE Blades, so I know MY head can do it. And yes, stress test computer modeling has shown that our head is capable of handling these weights as well, with a comfortable safety factor.

I predict that EDGE has or WILL do pull testing to see how well their blade roots hold up, and at what point they give up the ghost, but that is NOT general information typically passed out.

My testing was simply to see how each blade flew with the different weights, picking my favorite from the group for both Flybarred AND FBL.

These blades are now being tested by another company, so you can be assured that they are getting plenty of feedback on them, and will work with a variety of heli's and applications once available for purchase.

I think those that purchase these blades will be VERY happy with them! I can't wait for my own set to throw around with...

Semi-symetricals
Have you suggested semi-sym to them????

For purposes of FBL 3D flight, semi's are not a good thing....

For my Industrial birds, cameraships, etc, I again prefer symmetrical blades. There is less tendency to balloon in the wind with symmetricals. If you ONLY fly on very calm days, then semi's are great!

I feel the lift advantage of semi's is minimal when I can fly up to 40 Lbs All up flying weight with symmetrical blades. If I need to fly at higher all up weights, I go with slightly larger blades, say 850's....

If 800mm is going to be the new 700mm, then that means 14S will be the new 12S. Are any of the ESC manufacturers developing 14S compatible ESCs to go along with these new 800mm blades?

Kon Power Jazz and some other German manufacturers I think will go 14+S.
