[solved by new FW/SW 116/5.1] HC3 big issue
Hello, during March I bought an HC3-Xbase to put on my new Compass HV7.
During the first flight, maybe after 20 seconds, suddenly the heli started to go to the right. I fought a lot holding the aileron stick half way on the left and landed. I saw the swashplate completely tilt on the right. Then I went home and realized the following video (very poor quality, i'm sorry) but enough to show you the problem [ame]http://www.youtube.com/watch?v=IGeQ--ZXeWo[/ame]. So I contacted Robbe and Captron, and I return the unit to them for maintenance/repair/substitution. Yesterday I received it back and Captron representives wrote on the invoice that "the unit was checked and recalibrated and no defect was noticed. So it's ok". I retest the unit but unfortunately the problem is STILL THERE. I changed the radio, but the swashplate after some minutes started again to tilt right. I'm desperate, I've to buy a different FBL unit and trash this rubbish... but I can't believe that! Not from Robbe! Someone has similar experience or can have a clue to address this problem? Thank you all. Last edited by eriskio; 05-04-2012 at 02:32 PM.. |

Hi,
this is probably a problem/compatability issue with the transmitter or receiver. This is just my opinion but after spending £1000s on a 7HV I would never trust a crappy walkera tx with it. Get a DX7 or similar and plug in two sats directly into the HC and the problem will most likely go away. Staney |

Yes using a different radio is the next test I'll do.
But I'm satisfied by my TXs 2801, you known? They are not crappy actually, they have good range, simple programmability and some nice features (I have two of them so I've always a whole radio backup at the price of one) And I have no problems at all with others FBL units (2 microbeast, helicox, sjgd). Finally, as you can see in the video, is the HC3 software that shows all the commands received by the HC3 unit through the USB port: and here doesn't matter IF commands come from a cheap or costly receiver or a servo tester: in all cases what is failing is inside the HC3 unit itself. My personal consideration, obviously I would find a good person who can demonstrate that I'm wrong. |

Absolutley agree here. Youve spent good money on a HC3. Invest in a decent transmitter and receiver and you wont go wrong.

I can almost guarantee that this is a problem with the TX. I've got 5 of these units and use them with an Airtronics SD-10G with no issues. I've seen a lot of modelers use the Helicommand unit and I would recommend trying another TX to eliminate the radio from the mix.

Good to hear from you that your HC3 is NOT broken.
Do you have also a Compass HV7? Maybe is the heli that is not compatible with HC3 I'm joking, no way, I'll check in the next days with a futaba radio (and 3 servo tester so no radio will be involved and you all ends to go OT here writing about radios and not on HC3 issue... maybe ...I hope,,, ) The reason of my post was not to discuss quality of radio, but if there are others people who faced the same problem. And, as second options, to get some good technical advice, no advertisement. Anyway I accepted the idea to try other radio; thank you; what next now? Finally when I choose to try the HC3 my ideas whas to integrate HC3 in my own project/setup and not viceversa to create a project/setup all around HC3. But supposing also that HC3 has problem to getting signal from a radio (using the regular server ports to be clear, not S-bus or satellites) that is working perfectly with all others brands of FBL units, the problem is inside the HC3 not in the radio, doesn't matter the label it has on. |

This is exactly the same problem! absolutely. Mine also works right for some minutes (2-4 or so) but after that time, the swash tilt on the right and there is no way to get rid of it. It goes anyway down. The only thing to do is to shut down the units for a quite long time (some minutes maybe) and it start again to work, but only for a while. Is that correct? Please keep in touch, I'm really keen to know if you find any solution! As you know, mine was checked by Captron but with no luck. What do you think to try next? Oh! Please, don't try on your side a walkera radio... and I'll don't use a Spektrum DX8 on mine, I promise! I'm always sad... |

I'd say it's just something in the setup, I'd wipe the radio settings and start again .. might have missed something simple, just saying :-)
I have a few friends who just got the hc3-sx, ones on a jr the other a futuba and mine is on a bx8, all set with no issues, i did have some but it was just settings i had to change ,now it's fine .. Maybe if you know someone with a radio, set it up with there radio to see if it works, but i would think no matter the radio it should work, so therefore maybe a setting wrong ..' Also i set mine up in rigid mode first then sorted out the rest later .. Just an FYI Do the pots on your radio maybe need cleaning, just another idea .. Also update to the latest version 115 firmware if you have not already, and is the firmware in your radio up to date? If you swap the cyclic servo's (Plug) around does it then do it on the same servo or start doing it on the other one ? It could be many different reasons for it, to just flat out blame the helicommand unit is not very logical, but i understand where your coming from, it must be very frustrating ... Hope you get it sorted, it's an awesome unit .. |

yes, of course I agree with you: there is nothing wrong in your dx8 as there is nothing wrong in my radio.

It is hard to see on your video but it looks like the sliders on the Diagnose page are centered correctly when the cyclic stick is centered.
Is the swashplate level when the software is on the Trim page? Does the swashplate drift from center when the system in in the normal running mode? If so, how fast? Is it a slow drift or does it rapidly move to the side? What is the power source? Danny |

But when the swash start drift, then the problem is sistematic: you can power off and power on the unit but the swashplate (in normal mode operation, not diagnose or trim) always drift on the right side. How fast? I can't define it a slow motion, for sure about 1 second or less to go from horizontal position to the maximum position on the right side. Leaving the unit powered off for some time lead again to normal operation for some minutes. At the moment I power it with a 2S LiPo directly (no BEC). Thank you, Danny. Paolo |

It may be that your HC does have an issue. Please contact Joachim at Captron.

Problem gone with new FW/SW 116/5.1
Read the announcement of new software/firmware release this afternoon and as soon as I arrived at home, I did the following:
1) checked that the problem was still here. Powered on HC3, radio and software V.5.0: after 2 minutes the swashplate was tilted on the right as usual. 2) downloaded and installed the new software 5.1 3) upgraded firmware to 116 4) checked the zero positions of controls in diagnose window: found the aileron green bar out of zero to the left side (5 more points of subtrim to the right to get aileron 'zeroed' again). 5) left the unit working for more than 1 hour: the problem seems to be disappeared. Except for the subtrim I doesn't change anything else in my setup (and I leave the new deadband control to 'zero '). should I be happy? I hope...clues are that now my HC3 is working fine. I'll check it again tomorrow but I would believe that new software and firmare has solved the problem ( and I hope I will be flying my new heli the next weekend ) Thank you all for your help and support.
