HC3sx/DX9 tx settings ?

[tonystevens]

im setting up a helicommand on a friends 700, hes using a DX9 which im not familiar with. were going to be setting the horizon bailout up tomorrow so im looking for some settings for the DX9.
Id be grateful if anyone using this tx could post a copy of their tx settings to setup the bailout switch etc here for me or could point me in the right direction. only setup vids ive seen are using futaba 8fg?

cheers Tony

I used this for mine it's for a Dx8 but should be useful

Hi Tony,

Sorry I don't have a Dx9 so can't help with a setup file.

I always refer to this link when setting up a HC3SX:

My HC3sX and DX8 setup - HeliFreak

Hopefully this will help you get up and running quite quickly. I personally would not use someone else's file and prefer to set up from scratch.

Let me know if you get stuck on any part of the setup. I'll try and guide you through it from memory.

It's not too difficult to set up from scratch.

Surinder.

The Futaba videos were useful too in conjunction with the link in my previous post. Just watch the videos to grasp basic the principles and then translate the setup to Spektrum. That's what I did to setup on my DX18.

I see you've posted on the helifreak forums. The DX8 guide in the stickies will give you some decent pointers. To set the horizon and bailout you just need to set the correct positive and negative numbers in the channel and it depends on which switch you want it setup with so copying someone elses setup may not be the switch you want or the rapidness at which it Self levels or Rescues.

I take it you have already set the tail and head gain before programming the horizon mode? (Recommended)

Guide in post 43 will give you enough options depending on which switch you want to activate SL & rescue.

I have a DX8 and swapped the bind button around with the gear switch so I can press it easily with my left index finger. Quick press to SL or hold it down for SL and climbout. I guess it's possible on the DX9 if your freind is happy to take it apart.

cheers guys, i appreciate its always best to use a scratch setup but its just the settings needed to assign the switches to work correctly for the rescue features that i need. we have done the initial setup already, doing the flight parameters tomorrow at the field and hopefully get the rescue working.
Ive scince found some DX9 switch settings to get me started. For the purpose of the thread can be found here: Spektrum DX 9 settings for Rescue & Self Level - HeliFreak

I just wondered how you got on?

I just wondered how you got on?

After much collective swearing and chin scratching Tony sussed it with a little input from me. LOL

Must say its a good bit of kit, a bit over complicated to get the bail out and self level working, but that could be just me n Gadget confusing each other LOL

Am in the process of finally trying to set up the BD3sx for the first time and figured i would put it on the chase (since spares are hard to come by and it is likely to be my new trainer).

Have to say that it isn't easy and the instructions from BD are rubbish.

I sold my last helicommand without ever using it because i couldnt figure it out. Wonder whether this one will go the same way.

Swap for 2 vortex?

[woodsta888]

BD3SX was my first FBL unit I ever set up. The wizard is strauight forward and if you follow it you shouls have a fying heli. Lots of presets to borrow for different sized helis around the net.

Which part are you struggling with?

[Jez N]

Pretty sure i will have a flying heli. But assigning channels and setting up mixing for the bailout function is where i am not 100% certain. I have it now that the switches i want to use move a slider in the wizard, but not sure how that will equate to real life bailout.

Happy if i get it flying first and then will sort the bailout.

Compared to using the datapod and the vortex it is proving to be a relative ball ache!

Is there a way to test that the bailout is working on the ground? Dont want to flick a switch and find it does something silly and the model crashes!

[woodsta888]

Yep, The light will go green solid when in Self level mode and flashinggreen when in bailout. It really is just assigning a number to that channel which takes the gain for that channel to the numbers required for each. Solid orange is normal flight with no self level / bailout. Always make sure the light is orange before 1st flight.

I think before you set horizon and rescue modes they recommend you tune the head & tail gain. though it depends on how many channels you have spare.

Which switch are you assigning the rescue to? On my DX8 I have swapped the bind button with the gear button (physically moved them) and have rescue on that. Quick press on the button will show the heli quickly pop into the air. What you may need to consider is that cyclic can still over ride rescue so some people mix out any cyclic when the rescue is activated as naturally for some they still try and help with the cyclic.

The stock climb out on rescue is quite aggressive, especially if you use large blade pitches. Be careful if you are assigning rescue to a flip switch in this case as you'll need to switch back to come out of rescue and heli can get high quickly. Hence why I have mine on a push button so that rescue is deactivated on release of the spring switch. Self level I dont use except if I get something in my eye.

Something else to consider is that you can set self level for a failsafe too so if you brown out it will level and with a bit of neg pitch it will come down skids fiirst.

Sounds like you are fine with this and it's just the additional functionality the BD3SX offers with self level and rescue that you have been unsure about. So really, not that hard to set up at all eh?

Before first flight, make sure teh swash and tail operate in the correct directions bit tilting and turning the heli. Swash is level before spooling up and the light is ORANGE.

[AlastairC]

Just to add another thing to check before your first flight with it. To make sure you don't enable the infamous "rescue mole" mode. Go back to the tx diagnose tab and make sure your stick move the bars the correct way. Some folks to get the swash servos moving the correct way in the mixer step go back into the transmitter and reverse servos. In the mixer tab you must use the buttons on the software to change the servo directions not the settings in the tx.

As woodsta888 says above the rescue by default is very aggressive. So for the first few times I dropped it down a little.

Cheers,Alastair

[Jez N]

Thanks. Got the initial setup done and all the swash and tail move as they should. So reckon i would have a model that flew ok barring a few adjustments on the gains.

Was really hoping to set up the cyclic and tail gains to the L and R trim switches on the DX9 and then have the self level and bailout set to switches A and H.

I can really see the sense in having it set to a button that depresses, but the bind switch really is awkward to get to for a bailout switch. The one behind TH would be the easiest (although possibly the stupidest when i accidently hit TH instead of bailout!)

[woodsta888]

Yes the bind button is awkward. I had to take my DX8 apart and swap it with the gear switch. Some cahnge the lever switch for a sprung loaded lever switch. There si nothing wrong with using a switch that you have to physically switch off again, especially on the cyclic side of the radio as this has the added benefit of taking your fingers off the cyclic and not over riding the rescue. So it's not a bad thing. I used the aileron dual rate switch initially and they are still bound to that too as I dont use dual rates.
