How do you set max cyclic pitch?

[Lynx.1677]

Okay, perhaps I have figured out the issue, bit dark to test it out now but................

When I go to point L, it says to give as much swash movement without any binding. So I goto maximum. However, when I measure it at this point the cyclic pitch goes off the scale, as in, more than 15 degrees cyclic pitch.

Should I limit this point to a value that I want? I set it to 9 degrees but now my light is red where it was blue before.

Thanks,

Dan

No, once you have set the 6deg in J, set max/min pitch in K set swash tilt limit in L without measuring anything as this does not change the 6deg or the max/min pitch already set previously.

At point L, I set mine quite a bit less than the maximum available cyclic pitch as I figured it would just end up bogging the head (or stalling the blades?) if it could give 15 degrees cyclic (and even more when you factor in additional collective pitch). Can't remember exactly what I set mine to (TRex 500) but maybe something like 8 degrees.

Just get a min Vbar Blueline and be done with it.

You will be seriously impressed.

Sell the BeastX for £150, rx for £30 and you are only £40 off a Vbar.

And seriously out of pocket, you'll still need two satellites aswell

1 sat @ £15-£17, hardly breaking the bank.

Hey chaps, let's not go the vbar route just yet as I don't want to be beaten.

In point K you can only set collective pitch, not cyclic, so is point L where you set maximum CYCLIC pitch? Mine was cranked all the way up to give the system as much as poss as it states in the manual. When I measure it at point L though it goes off the pitch guage, probably 16 or 17 degrees cyclic pitch but not sure how that equates into what the system actually uses. I went on the beastx forum and it states:

"Make sure that in Setup menu Point L the cyclic deflection is set to absolute possible maximum. You should have at least 10 - 14 deg of cyclic pitch there."

Which seems a bit vague to me, how much will the system use?

I have 6 degree's at J and the famous blue light.

Hi Lynx,
It seems that you have been struggling with this for a while but I think you are probably on the right track now.
When I setup the Beast on my 700 I had a ridiculous amount of collective pitch. I am talking around 25 deg or so! Of course this much pitch would easily cause the head to bog as well as put a massive strain on the servos.
So, firstly make sure that you have a mechanical setup such that you can get the blue light on menu J when at 6 degrees as this ensures that you have the correct resolution required.
I see that you have already doen this.
I then limit the travel in menu K to +- 14 deg and I think this might be the root of your problem as you are probably over pitching.
In menu L I have not needed to make any adjustments as I don't get any binding when at the extremes (well only a tiny bit). I did find that if you did adjust this menu then it affected the whole range of the pitch not just at the extremes (like a cyclic ring) and this was undesirable. On a side note the Vbar apparantly has a double cone where this function only affects the extremes of the pitch curve.
Here is a setup video explaining the process.
Hope this helps.
Ade.

If you think about it Dan if you have too much then coupled with mad collective you can easily reach stalling point, what is it about 16 degrees. I set my cyclic to 8 degrees as I would normally giving a little extra just in case the system needs it.

Okay, thanks guys I think I am getting there. What is unclear is where do I set my max cyclic pitch? Step K only allows me to setup collective pitch which I have set to +/- 12 degrees which is fine.

Do I limit cyclic pitch at step L?

Yes. But I didn't need to do this on mine. i.e. I left mine with +-14 on cyclic as well.

Even the videos make the instructions a bit ambiguous. In the video it says to max the cyclic out without binding. I must admit it is a bit confusing.

Hmm. Also on the BeastX forum, even the experts can't tell me what the issue is and why I have to fly it so gently to avoid the beastX making the heli do a chicken dance. They just tell me to set max (without binding) swash movement at step L.

Makes no sense that you don't need to know what cyclic pitch range your heli is running yet you setup your max collective movements. I think there is a definate programming issue with this unit if that is the case and it's somethiing I am not sure there is a soultion to. As it stands, I would rather go back to the 3G unit, it wasn't as stable but at least it lets you setup your max cyclic pitch range which is just logical.

As far as I can tell it is definitely step L where you set the amount of cyclic pitch. It's not just acting as a 'cyclic ring' at the extreems of travel because it seems to work all the way through the collective range -just like setting your cyclic pitch with a flybared head. Even though the manual seems to suggest you should set it up for the maximum possible pitch I just can't see why you would set up for 15 degrees cyclic -this would mean a blade could end up being at close to 30 degrees with full collective AND full cyclic i.e. way beyond stalling point. Got to be worth trying lowering your cyclic pitch and see what happens.

You see this is what my issue is. The guys from BeastX are adamant that I have to have max throws here. I'll lower it to say, 13 and see how that feels. There's just far too many 'read between the lines' information from the BeastX guys rather than 'this is where you set max cyclic pitch'. Heck, I don't even know where to measure what cyclic pitch. When the heli is powered up and ready to fly I measure the cyclic pitch when my throttle stick is at 50% and it reads 11 degrees. So yeah.................totally confused.

Thanks mate.
