What is stated is the HC software is: " Allowed only for models with exactly symmetric c.pitch range (positive = negative,
in the diagnose tab, and at the rotor blades' angle of attack)".
Yes, that's it. The only points of interest in the collective curve is symmetric end points at 100% and centre signal at 0° attack angle, speaking of the 3D modes.
If flying "hover&scale" it is not that sramatic.
I am terribly sorry for this and apologize for any inconvenience it may have caused you. I've slapped myself twice (OUCH!)
Next time we meet, remind me to give you another one ;-))
Seriously...I agree with GetToDaChopper: you do more than a great job here, so no need to hurt yourself ;-))

You said,

it is not that urgent to watch for a linear pitch curve. Actually if linear or not isn't of any interest for the HeliCommand and is not stated as this in the manual anywhere. Only the end points of the Diagnose's collective bar should be reached, so the HC knows the full travel.
In the case of flying scale it is even ok to use Dual Rate to tame the heli and get the curve down. Everything will work fine for sure. Expo of course is also allowed to be used in the Tx.

So just to clarify are you saying a linear pitch curve is not at all neccessary so long as the diagnose collective bar is met at both ends.
In saying that does the diagnose bar have to be met in all flight modes for this to work or just a one of in the initial setup.
Buy this I mean can the pitch curves be reduced at both ends to reduce the amount of pitch available for a beginner so to speak. will the system still work this way.

thank you

the hole point of diagnose bar is to let the Helicommand know what the control range of your radio system is (futaba, jr, ect) and for that you must use linear pitch and throttle curves then adjust your radios end points to hit the lines on the diagnose bars then you never adjust those again, ones that is done then you can go back and adjust your throttle and pitch curves to however you like, you could have a pitch curve of lets say "50-50-50-90-100" with no neg pitch if you like because when you hit the rescue button the HC3-SX will ignore your TX pitch curve in favor of the pitch % you've set in the setup GUI just remember to not chop the throttle when ingaging the rescue feature (acro with pitch) because the HC3-SX does not ignore the throttle curve in the TX, i would make sure you give it enough throttle because the more throttle you give it the faster and harder it will preform the rescue.

is this correct Joachim ?

Well Folks, having lived with this unit for a few days now I would say that you can feel the unit working with horizon mode on in fast forward flight and in fast turns. This is because the unit is trying to stabilise the helicopter at all times. However it is not that intrusive and certainly takes no practise or getting used to. Remember this is with horizon mode on at all times which you can switch off with a flick of a switch and then you are in normal flying mode.
I will be posting a video soon to show how fast you can fly with horizon mode on all the time.
I have to say so far I am seriously impressed with this unit, it makes the heli have the stability of a contra rotor heli but with the flying capabilities of a normal heli.
This means that a novice could be flying any heli fitted with this unit in a very short space of time since in horizon mode all one really does is to steer the helicopter about like a radio controlled car, rather than actually fly the helicopter.
In this respect it could be a very good beginners tool making learning safer for the pilot and those around.
Just my thoughts so far.
Hope this helps, all the best Bell Bloke

Mr. Bell Bloke, Sir,

Thanks for posting. I love my HC3SX's. Your reporting has been very helpful - having that particular assessment coming from you is meaningful to me, at least. I'm wondering what gain you were using in Horiz mode? You had it on a 450 if I remember correctly? Have you had a chance to try it on a larger heli? Finally, I've almost completed an AP bird and I'm using a HC3SX on it. I like the fact that one can steer it around whilst taking photos/vids. I also have one on my Century Bell 47 and it's really fun. J

I am getting my Reactor X2 this week so I be setting up the HC3-SX. I will have some questions I am sure. I will be using the new DX7s.

Thanks in advance.

Well Gents, like I say I'm no expert on this unit and so I have just got it on the default settings for a flybarred heli.
I have not done anything clever or complex with the settings at all, this unit has worked perfectly out of the box without anykind of fine tuning at all.
Hi Jockobadger, the heli I am using is my old Century Hawk 50 which I converted to electric years ago, it's on wooden blades, so a real back to basics set-up. This is for me a way of testing the robustness of the unit with a machine that is deliberately not perfectly in tune. As you will see from the video when I post it, the unit does a great job, to be honest it may be hard to see how stable the heli is in the video, but take my word for it I am no longer flying the helicopter I am only steering it around the sky.
Once I get some more flying time on the HC 3SX, I will start to play with and fine tune the set-up just to see what it does but to be honest it's so damn good I can't really see how it can get much better.
The head gyro is set to 50% on flybar by the way, and the hawk mechanics are the same as your Bell 47 as you know.

All the best Bell Bloke.

OK Folks this was my first time out with the HC 3SX and it was a little out of trim at the start.
The idea was for me just to get the hang of flying the heli in Horizon mode, I was also trying to unsettle the HC 3SX while it was constantly in Horizon mode which it remained in for the entire duration of the flight.
I was not planning on putting this video up as it was my first go with the unit, however this was the only time my girlfriend was there to film it in action.
In a way it's good because you get to see my first attempt warts and all. Obviously this is no 3D heli it just doesn't have the power and anyway as you can see it's an old cameraship from yesteryear.
On the first lift you can see the heli is drifting slowlyish to the left, by the time I do the piroettes I have clicked in some trim on the tranny to stop the drift and all is well.
You will notice that the 'Hands Off Cyclic' text comes on even when the heli appears to be in fast forward flight. This is because the HC 3SX is a device for leveling the helicopter in Horizon mode or 'Captain Bailout.'
That means that if I am in a fast turn and I suddenly let go of the cyclic the helicopter will as you see go perfectly level...however the momentum it is carrying in the turn gets carried through into forward flight and so the helicopter remains perfectly level but it is still travelling forward. Given a big enough field it will run out of momentem and stop on its own.
Please note also this was not an exercise in smooth flying, quite the opposite in fact as I was trying to provoke the unit into doing something odd, which I am happy to say it never did.

Hey Guy's, Flew one of my trex pro's today for the first time with the HC 3Gsx. One of my friends set it up for me and I wasn't quite sure what to expect. After just a couple of flights I found myself really liking this unit.

A couple of flights I kept the horizon mode on the whole flight. He dialed the mode down to 2, but it still fights to stay level. With the unit off it's just as good as my BeastX.

The cool part is after you start to get the feel for it, you can do fast forward or whatever while in level mode. You just have to keep some push on the elevator during transitions. No fear of losing orientation. It wants to be level

I'm getting a Logo 600 in a couple of days and I think one of the first things to go on it will be the SX. Great unit!

Thanks Bell Bloke - that was great (where did you get the undercarriage on that baby?) AerialSkyCam - You may already know this, but when it comes time to set up your Tx, be sure to check out several threads on HF - there is a goldmine on programming the mixes so that you can get Horiz/Rigid on one switch and level with pitch (bailout) on the trainer button. I'd be happy to send them to you if you like. It works great, but it was a bit challenging to figure out - for me at least. Thanks again BB.

Yes, not at all necessary. BUT: not only the end points but also the 0% center signal = 0° attack angle is very urgent for especially "Captain Rescue" to work correct!
And yes, you need to have these particular settings correct in all flight modes.

From what I read here I think I have to clarify one thing, which seems to be misunderstood very often.
URGENT: The HeliCommand systems DO NOT learn anything and "save" it, never, neither in the Diganose page nor any other stage of the programming!!!
What the Diagnose gives you is a possibility of checking and setting up all your Tx signals to fit the HeliCommands needs, meaning you set all signal so the HC does what you want him to do. But once again: at no part of any settings the HC will "learn" anything...he only "looks" for signals, never learning them.

Hope I made it to point out this one clear enough now.

Hi Bell,

you exactly pointed out the more than 10 year old initial idea, causing us to develop these units :-)
But also, nowadays I have to say, that we do not only serve beginner needs, but a lot more.
But anyway, good to hear that the basic idea seems to be seens as what it is :-))

Hi Jockobadger, the UC and pod is just something I made ages ago.

The video really doesn't do justice to what this unit is actually doing, it just looks like I am flying around, but trust me I was constantly letting go of the sticks in hard mid turn etc and watching the heli instantly level itself...perfectly and with no drift at all that I could detect. And thats' on this old helicopter with 35mhz radio and wooden blades, so you boys with your posh carbon and titanium sky burners should be laughing.

Hi Joachim, this is the unit my friend had the trouble with, he is now looking at his power supply, so it looks so far as the fault lays with him. I have to say it's great to be able to talk to someone on the phone if you have an issue, your service is excellant as is your advice and of course your latest creation the HC 3SX.
I will be getting me one of these asap as I am pretty blown away by its performance and it's elegant constuction. No plastic cases for you guys, METAL is what you use and that really gives one a feeling of quality the moment you take it out of the box.
I bet you could drive a car over the HC 3SX and it would emerge unscathed....now there's a test!.....No just kidding.
Ultimately this units capabilities will bring new people into the hobby I think, as it makes things far more accessable and safer in the beginning and probably later on even with more seasoned flyers.
All the best Bell Bloke.

Thanks Jockobadger. I have been following this thread everyday reading all the info. Unglucklicherweise, my bec has not arrived yet so I cannot set anything up yet. Should be here Wednesday.

Bell Bloke, I see you are powering with 5.2v. How is that working for you?

Well, I think I answered this 5 posts ago already. Let me know if there is still anything not clear, as all is in that post actually.

The main thing is, that the HC does not learn anything and afterwards you can do whatever you like. This is a common misunderstanding which I again and again try to eliminate :-)
All you can programm is the Tx, not the HC regarding signals.

i'm sorry but i'm still not clear on some things here

it does save "settings" like % of pitch for rescue mode or tail servo travel limits when you "write" to the unit does it not ?

so it does not "learn" anything but you "save" a lot of "setting" when you "write" to the unit ?

things like % of pitch for rescue mode or tail servo travel limits or mounting side or swash type or main rotor direction and the list gos on and on, all those "settings" have to be "saved" in the unit when you "write" them to the HC3-SX because there def are not saved in the TX, correct ?

if those "settings" were not "saved" in the unit you would have to input all those "settings" every time you turned the unit off and on ???

EDIT : this is for anyone that might think i'm trying to pick a fight here, this is NOT my intention at all, i'm just trying to understand my HC3-sx as best as i can and i'm thinking that there might be a bit of a "language" prob here but make no mistake picking a fight is NOT my intention at all, please understand this.
