Well, Perhaps I should come clean and say a little of what we are up to in this direction. We are currently testing in almost final form an on-board CCPM mixer and we have several pilots assessing the use of this in conjunction with two SL720 gyros. We have been encouraged down this route by promising results of tests of a pair of SL720 gyros in a non-CCPM flybarless machine. Of course the gyro control needs to be rather different in cyclic applications to that used on the tail but the adjustability of the internal settings of the 720 means we have not had to do any changes to the core code of the gyros.

I would very much like to gather people's opinions of how they would like to see the system but I'm aware that this may be a diversion from the intention of the thread originator here. Should I open this discussion in a separate thread?

Best regards

Open a new thread Colin. I'm very interested in this technology. Do you mean you might make a version that uses 2 720's on one board?

Sorry Scott - I have been 'told off' a few times for diverting threads so I thought I should be careful! Thanks for the permission anyway.

Hi Scott - yes, my feeling entirely. I am, it has to be said, one of the worst thread manglers around.

I don't think anyone will have anything bad to say about the Flybar system , all I was saying in the beginning was that $1200.00 dollars is hefty price to pay . Especially when you can get a RTF heli for that or little less . It looks like Colin has something to in the works that is on the same lines ( i leave that to Colin ) But much cheaper . So that would be more on my type budget . There is no way at all I could shell out $1200.00 not with my last son going to college . That is just one big lump at one time , all at once . Well that's my 13 cents so I will close now and ponder yet other things of life changing consequence .
Good Luck To All

If I can be so bold as to ask, why do we need one? is there limitations that a flybar can not provide?

Dont get me wrong, if I had the extra money to dispose of, or I was an expert 3d pilot, I would get one.

I think its about the drag the traditional flybar adds to the whole system, not to mention possible tiny missalignments that will affect performance without you ever noticing it.

I chased a little problem on my evo 50 for about 2 days (it had the tendency to dive during FFF) and finally I found the problem in the flybar paddle alignment. I'm sure the flybarless setup will have other problems but it can't be any worse than chasing a 0.5 degree off paddle.

Another advantage would be for scale flyers. Its a pain to fly standart flybarless (scale) heads.

You dont need one and you probably dont need a 14 MZ either

One reason to get it is if you have an electric heli and want more power or longer flying times and all ready have invested in motor, esc and a pile of lipos.

Another reason is that your head will be extreemly configurable. You can also exchange setups with friends (through XML) if they have a similar setup as you - should be interesting for comparing blades, lipos, motors and stuff like that... as you can see I am totally hooked on the concept

I agree with Lorents all I can and ever said was the price is just to much for me . Now after it is out awhile and the price comes down we all will have them but this is the first out starting price . Remember when VCRs were $1200.00 and they had the push button keys . Now you can get them for less than $100.00 . This will (maybe) do the same .(I Hope ) So I think the only thing holding us back is price . The unite itself I would love to have but it's the cash flow or lack of it that holds me back . Let us know Lorents how you make out .

Hi Lorents

Well done. Some video would be good if you could manage it.

BTW did you see the Dave Nolan's thread

http://www.runryder.com/helicopter/t303432p1/

about his first flights with the mixer and 720s? He has posted a video on his 3D heli Ireland site and there is a link on the tread to that.

Best regards

Thanks Colin, I saw the thread and it looks great

I havent really flown it yet, but one thing that surprised me about the Vbar system is how familiar the helicopter was to fly. I am looking forward to get some time in the air with it.

Are you running the 720's in HH mode on the flybarless heli or do you use rate mode?

Hi Lorents

The 720s are set up to have two heading lock modes which at the moment differ only in the heading lock decay times. Mode 0 has a short decay time (1 second) intended for ease of hovering manoeuvres while Mode 1 has no decay.

Ah, so you would have a stable setup in idle up one and a fast setup in idle up 2?

When the helicopter is on the ground will the swash plate "creep" like the tail does since its controlled by the 720's?

That's the bit that scares me. I suppose if you control the gyro gains in parallel, then you can lave it in normal mode until you are about to take off. Same as what I do with my tail gyro just so there are no supprises.
