HC3SX connection question

[Hummingbird]

hi all,
Have any of you got a Blade 450 3D (THE FLYBARRED HELI) with a HeliCommand HC3SX? I know it's a FBL unit but it can be used with a flybarrred heli. My question is: can I use it with the stock receiver or do I need to buy satellites? And what plugs into what. Yes, I have read the manual but, as others have also found, it's just too confusing. I think can make sense of the setup once it's all connected, but I would appreciate some guidance on plugging it in. Is there a wiring/connection diagram anywhere for the stock receiver (Spektrum AR6115e)?.

I also have a Blade 450X FBL and a Trex 550e Flybarred. My plan was to practice with the HC3SX on my battered 450 3D then, once I'm happy with how to set it up, put it on my 550.
Any thoughts welcome. Thanks in advance.

You can do either - connect the sats directly to the HC and not use any receiver at all or you can use the receiver and hook it up to the FC.

The wiring diagram is in the manual on page 5 - I can email you a copy of the revised English version rather than the German translation if you wish - just PM me your email address.

Its a confusing manual - you will need to read it at least half a dozen times !!!

Thanks Skipper Billy, I've sent you my email via PM.

Setting up the HC3SX for a flybarred heli is almost identical to a FBL. The only difference is that you turn off the electric flybar on the Rigid tab.

So, you have to set up the TX exactly as if it is a FBL heli using the DIAGNOSE tab and then from then on you don't adjust the tx except for D/R or Expo. You centre the servos and level the swash just as with a FBL and then set zero pitch and pitch range. When you have set it all up you can then turn off the electronic flybar in the RIGID tab and you are then ready to fly to set the gains. Once the gains are set you can then turn on Horizon mode and set up the S/L and bailout.

You must remember that although you will be using the flybar on the heli to provide stabalisation it is still the HC3SX unit that is controlling the heli. It is much more like a FBL set up. The benefit of this is that you still have available to you the self-leveling and bailout features.

If you have 2 sats (ideally DSMX) it makes the wiring a whole lot simpler but it does work fine with a receiver using the wiring harness that cames with the HC3SX.

If you want me to pop over and talk you through it then just ask... I only live in Saltash. I could bring my heli along and my laptop and show you how to set it up. I recently did a flybar setup on my 600E and it all worked fine. PM me
