New & Emerging R/C Helicopters > CX Programable Head set-up?

Hello Guys,

For those who are using the CX Prog head (Pete Niotis, "Chopper", Agusto, and others...) what is your set-up for extreme 3D? Can you post some pictures?

Regards from France

Olivier

PS : I've ordered mine and it has been shipped yesterday. Cool...

Define "extreme 3d"? Besides how Pete, Augusto, or anyone else flies for that matter may not suit your style. You can copy any of the pilots mentioned set-ups and not like how it flies due to many variables like radio set-up, servo/gyro selection, and etc.

Hi Carcrasher,

You're right. What I want is a good combination between cyclic response and good acro auto performance. I'm currently using the EVO head with the the thick delta spacers, CX dampeners "C" with no shims and 70 durometer o-rings. Blades are Radix 690, gear ratio 8.08 and my RPM is around 1950 (OS91 SZH with perry pump running on 30% with hatori 938). This combo is really good for my flying style, so I would consider to start flying the programable head with the same feeling for the biginning.

Thanks

You can start at this point:

1)Position 7 of the delta settings. (4 is Zero delta). That # 7 position is using holes number 3 on the bladegrip and holes number 2 and "A" on the bladegrip pitch arm. Lower numbers make the cyclics more responsive. Higher numbers make them less responsive.


(The pink dot indicates the location of the bolts)

2) Outer hole on the mixing arm's short side and middle hole on the mixing arm's long side. Middle hole for the double ball in the flybar ratio (side with a single hole)



3) Don't forget to adjust the phasing to match your blades and eliminate corkscrewing during rolls.

I asked Augusto the same question. I had the Avant w/ the x-spec head, CX dampers v2. It's hard to say what will get you close to what you have now. I went with the number 6 for delta spacing, the 5mm balls on the are set outside hole to the right and middle hole to the left.I also have the stock (60 duro) orings and the double ball for the fly bar in the middle. I'll see what this gives me. I I also have no weights in the stock paddles.

carcrasher,

You should flip the mixing arm so that the longer arm is on the right side. It allows for more movement of the flybar control arms. It will change nothing as far as the ratios is concerned.

Arky,
No we are not planing on making that a 12mm version. It would take quite a bit of re-designing to make it all work.

Can I fit this new head into Predator gasser? Since both heli uses 10mm shaft.

Cheers

I have no idea. I'm not familiar with the Predator head enough to give you an answer.
Sorry about that.

Hi Augusto and Carcrasher,

Thank you for your answer. I'll try this set-up as starting point.

You would have to drill and tap the main shaft on the Gasser to mount the head (4mm). The mechanics of the head will work, but you will need to change the washout block as well. Any Freya or Xpec washout block will work with the new head on your 10 mm shaft.

What is the maximum blade length that I can put on this new rotor head?

Hey Augusto, why do you make stuff that is Freya compatible only. We, non-Hirobo guy like and appreciate the technology you are making. So why don't you make stuff that is compatible on any brand of heli. Hirobo is not the only players on this game.

It is compatible. It is just not a direct bolt on.

Any weight advantage compared to xpec or evo head ?

The weight difference is not meaninful in this instance. The AVANT head will stay in track in all maneuvers. No boom strikes, not out of track. Very predictable.

Honestly I haven't weighted them myself but somebody that did told me his programmable head was significantly lighter than his X-Spec head.

Regarding the 12mm mainshaft question, it seems like it would be a rather easy thing to develop a ground mainshaft that stepped/tapered down from 12mm to 10mm(?) to adapt the head to other birds. The taper or step could occur either above the original swash to retain the original swash, or below the swash to use the hirobo version. Thinking about it as I type, I suppose even a steep taper would be preferred to a step in order to minimize stress concentrations along the circumference of the diameter change. Just a thought for someone interested in putting this head on your bird, or maybe for Augusto and corp to open up their market.

One thing I forgot to post:

The angle between the mixing arm and the rod coming from the swashplate needs to be 90 degrees when the blades are at zero degrees of pitch.

Many people make the mistake of trying to make the mixing arm level and doing so you won't get equal collective pitch right side up and inverted. You'll end up with more pitch inverted and your rod will appear to be shorter than needed because you're trying to incorrectly reach a point that is out of the reach of the rod.

Here's a drawing of the correct setup:



From a 90 degree point the travel of the swashplate up and down will give similar end of travel angles on both pitch extreme positions.
