Summary :

- Hei in use is Gaui X4

- Having issue with the recovery ACRO with Pitch...loss confidence. All working including recovery switch and the heli will recover +ve or -ve when I just do a testing/demo where I am not really flying.

- Once I fly my normal routine with lots of piro(s), tic toc(s) and learning piro flips ... it seems like the HC3-SX lost its Leveling Position.

- Once I was flying my usual routine, I decide to hit the emergency while it is in normal upright fwd flight, the Heli just plunge down to earth and crash it. I have no idea what happen.

- Rebuild it and fly well for 10 flights , decide to check and realised that when just initialize the test on the emergency work fine +ve pitch apply when upright and -ve pitch when inverted.
But after flying my usual routines....I land and do the test flipping the switch...while the swash pitch up but it also apply some aileron on it. This is scary..here are two videos to show - part 1 (just initialized ) and part 2 (after 4 mins of flying ).

Part 1 : http://www.flickr.com/photos/26456268@N08/5460741719/
Part 2 : http://www.flickr.com/photos/26456268@N08/5460739751/

- you will see from the video, my telemetry is showing the receiver (aka esc ) stay at 5.5V to 5.6v through flights....

Do you see the same problem as I do ? ANy advice ?

Here are picture of my helis, you will see the HC3-SX is inside the frame while the two satellite is wired outside along witht he telemetry TM1100.

Guess I am right

Looks like they found the issue I am facing with :

=== from Helicommand website ===
Furthermore, using the HC3-SX and flying constant, long-range figures, a noticable drift of the internal horizon may occur. This may lead to a malfunction of the option "Acro with pitch" as well as the horizontal stabilisation (self-levelling). For this reason, as the manufacturer, the mode "Acro with pitch" of the HC3-SX is not approved and the use must cease immediately until further notice.
=====

But it have cost me at least two crashes already

I am concerned about this thing?? although i dont use the self level much. I believe i was told in certain modes, if you do too many maneuvers in a row it will confuse the HC3 SX?

I am liking that heli you have,how does it fly?(any flying videos?)

Settings

In reviewing your settings, I think it would be best if you set collective with pitch to 5 instead of 10 which is max collective. A slow gentle climb is much better than a breakout at bogging performance.

That issue that you talk about is being investigated and hopefully a solution will be out soon. I too own the unit and love it. In fact, it has already saved me once from disaster and saved my model, hence paying for itself.

Hi Jonathan,

the issue you are facing may not really be the problem we are currently investigating. What you should do is not only look at the swash tilting completely to one side after the flight, having the heli on the ground or bench. The thing you recognized means that the horizon is not 100% accurate any more and that the system tries to bring the heli into the "new" correct horizontal attitude. To see how much out of level this is, engage the self-levelling on the ground as you did already and then tilt the heli in the direction the swash goes, like if the heli would follow the systems commands, exactly until the swash goes back ortogonal to the rotor shaft again. The angle you are holding the heli now is the real angle in which the system would stabilize the helicopter in this moment. I assume a few degrees out of centre usually, which would be compensated again if you go on flying. There is always a little drift inside, totally normal, as long as it is not too high.
If it is far out, more than 10-15°, you may be affected by the issue we are currently warning about.

Let me know in case you manage to try the above. Would be interested in how far out of centre your HC is. And also a video of the flight would be nice.

Joachim

Follow up on Video

Joachim,

Good to see your updated post on the other thread.

Here is a video of how I fly:

http://www.youtube.com/watch?v=BOK2...n_order&list=UL

Here is the video done yesterday follow up to what suggested.
http://www.flickr.com/photos/26456268@N08/5525709263/

I try to do exactly as your post suggest...after landing I took the heli to record video. I hit the emergency switch and you see the swash tilt backwards....I then follow the swash as if the heli flown backwards to get the swash align to the main shaft. Then try to record the helicopter position.

Let me know what you think ?

I did previously have the same issue you share in other post that on hitting the emergency switch it actually give the wrong pitch direction and plunge it to the ground.

Hi Jonathan,

yes, that video (the second) shows just what I tried to explain: the horizon is actually by far not that much out of centre as you may think when the swash moves backwards all the way. This is related to the Rigid system, which is not giving absolute servo ways, but turn rates. And it wants to do this attitude correction as fast as possible.
So the real horizon is only a few degrees out of centre. Happy flights :-) Just take care about news regarding the 'acro with pitch' mode. Rest seems to be fine.

BTW: nice flight :-)

Joachim

Joachim,

So now I just wait for the new firmware that will be better for "acro with pitch". I can test the beta software also if you want :-)

Hello All

I will be recieving an HC3-SX very soon. I will be posting videos as well

I never got the change to video any flights with this system but it does fly really nice. And for my the auto correct to upright with no vertical climb always workded. I do not like the vertical climb because it dissorients me more the smaller the heli gets

Resolved

With Joachim verification, more confident to try out something through programing. And it work out well, very much do what I want it to.

Day one I wasn't sure if it can have practical usage since you need both stick to be in neutral to work ( with this test , to work properly ). I am not sure if i can get my collective/throttle stick to neutral when emergency arise to hit the switch.
I believe after the following test, all my previous issue could arise where I might have not knowing have my collective/throttle stick at some position that lead to funny reaction.

so here is the fixed that I do to make sure the collective/throttle stick is always zero when I hit the emergency switch:

1) Program the emergency switch (SE) that I have been using ( not idle switch ) to have both position not trigger the "acro with pitch" , orange light instead of green.

2) Program the pitch curve on Idle 2 to be all zero on the curve, to ensure it is neutral position.

3) Program my Idle 2 position to be the emergency switch that I use to trigger "acro with pitch". This is done with program mix#1 to have the orginal emergency switch (SE) to have an offset value when idle switch is in Idle 2...this offset is also the value that drive the horizon gain value...the diagnose screen is very useful in aiding the programing as you can see the value live.

Now everything work perfectly....when I hit the switch , idle 2 , position in any flight condition ( piro, flip, fwd ) it just goes upright or invert and stay there with a slow pitch up to the sky. And I actually now have the time to just steady myself and decide the next move as the heli just seat there and wait.

And as Carlo said, it fly very well. And now it recover very well also.Loving it now , not for sales anymore:-)

If the collective is set on the bail out switch to be 0 pitch wouldn't the heli sink? Doesnt there need to be some pitch in the blades to maintain a hover?

luckyflyer,

No it won't as the acro with pitch will add the correct pitch input depend on weather it recover the heli upright or inverted. :-)

Hello

This was explained to me back when I first flew the system and the collective pitch stick must be set to 0 pitch(mid stick) BEFORE you hit the bail out mode...

This is one reason I prefer to use the mode that corrects to up right with no bail out. All you have to do is hit the switch and control the collective yourself.

With acro with pitch, you have to remember to center the stick AND hit the switch...which is a little much for me when I am in a jam. Also the heli asending throws me off.

Carlo,

I am with you there that it is too much for me to remember center stick and hit the switch. With the programming using idle 2, I by pass the need to remember center stick and it work out really well for me at this point. Hope I don;t bump into those problem they are trying to solve on acro with pitch now. I set it then the climb is not much just through programming on the tc, and it seems now that it just apply anywhere from 4-5 degree of appropriate pitch, and I find the heli just seat there dead on with minimun pitch up.

If these continue to work well for me over the few days of flying...then I wouldn't recommend other to do the same. And also for helicommand team to probably programming in to bring the pitch to zero while leveling and then pitch up.

Hi Guys,

Just like to find out from you, what should be the correct behaviour when the bail out switch is activated? Currently, the mode Im using the "Goes to Pos" option. When I activate the switch, although the heli will level itself, it will still continue moving in a certain direction. Is there a way to minimise this effect? As in, let the heli hover or move in a slower fashion?

Thanks

This is normal as the system does not have a means if detecting and canceling drift. It only self-levels. Check that the Horizon gain is set to 100% in the Diagnose tab. You can also lower the "Self-leveling end phase" in the Horizon tab. This should help it level quicker but the machine will keep moving a bit if it has any appreciable velocity.

I just got the HC3 SX in the mail.

I will set it up on my own personal machine.

I will fly the piss out of it next week and let you guys know how it went via a few videos.
