Music wire for flybar? Flybarless queries too

[fab_chan]

There's been so much talk about adding weights to get more rotating mass so I thought, can I just replace the CF flybar rod with a heavier music wire? Before I jump into this, I need some expert opinion from you gurus out there. Also, I've been toying with the idea of flybarless-ing. I'm considering cutting the flybar rods until only 5mm protrude from either side of the rotor head, CA a ball socket to each end and connect the flybar push rods to them. I assume that this would allow the head to tilt with the swashplate and result in better response time. The issue here is will this method stress the balls on the swashplate and snap them off?
Thanks guys...

wow....
cp uses a music wire for the fly bar rod. not sure if you shorten it like that how it would response but though i'm not very sure, i think the longer the flybar the more sensitive the picc is to cyclic response but finer adjustments must be made to the alignment. anyway just remember to buy some spares before trying it out!!

another experimenter has joined the ranks!!

go ahead and use the music wire flybar. i would use it except for that fact that i want to use J's flybar head bearings

i like the carbon flybar better. if you want to add weight to the flybar for stability, use wheel collars. they are available at the local hobby shop.
i use the music wire because of the flybar bearing mod. the music wire is a perfect fit to the flybar bearings mod.

What size of music wire are you going to use? I was going to try some brass tube or the like next trip to the hobby store.
I did buy some bulk cf from Sky Hooks and Rigging on the 8th, but its not here yet... I'm a little impatient at the moment.

2mm, i suppose. That's the diameter of the original CF rod.

Ok, on the fly bar issue. Here's how the original concept works. Servo pushes the fixed star of the swashplate causing it to tilt. Pitch-change links (push rods) on the rotating star rises and fall according to the plane of the swashplate. The up-down movement of the rods changes the pitch (angle) of the FB paddles, causing them to rise and fall as they turn. This creates a rocking movement of the FB CF rod which in turn, pivots the main blades.
To trim the process, I was thinking of pivoting the blades with the swashplate by shortening the FB, CAing some ball socket and connect the FB links to them, effecttively creating a direct link between the swashplate and rotor head. My question here is, are the balls on the swashplate strong enough to rock the rotor head 1,000 times a minute?

2mm yea, ok. I didn't know if you had anything special up your sleeve.

which means no paddles...
wait you have to fix the flybar to the rotor head or there'll be no effect. next, you'll lose one rotational degree of freedom from the head as you're only left with the teetering of the rotor blade unless you mod the main blades to accept pitch then if that's the case you'll get Collective pitch flybarless but instead of pitch control you are doing it from the teetering side.
From what i can visualise the movement of the rotor circle (formed by the rotation of the blades) seem funny.. dunno.....just hang in there and wait for the gurus to answer

anyway the flybar paddles for fp controls the virtual pitching to provide directional change that's why when tracking is out for the main blades the next step will be to adjust the flybar paddles.... [img]/ubbthreads/images/graemlins/smile.gif[/img]

I use a steel music wire flybar, if you cant get hold of one i sell them on my site.

This just came to my mind out of nowhere:

What if flybar paddles were replaced with another set of blades? Of course all the blades would have to be cut quite much to get the head speed high enough. I was thinking of a very short (same size as the rotor head) flybar that the control arms would be attached to. New blades would be somehow attached to the ends of the flybar.

It would be sort of flybarless 4-bladed FP thing, but I don't know if it would actually work. Stability and blade tracking could be quite interesting. It could be cool, tho, with a fuselage like RAH-66 or H500 or something like that.
