HC3sX dialed in and tested bailout Woohoo

[Sambuka]

Finally got the blade 450x with hc3sx dialed in and programmed in bailout at
-50% (half speed bailout level) set it to the gear channel in my dx8 with aux3.

The guys at the club were quite interested in finally seeing the bailout work as they were used to crappy older systems that never worked well. I flew the 450 high flipped it to knife edge and hit bailout gear switch the heli just flipped itself inverted and did a slow climb till I flipped it off. Kind of surprised me as I wasn't sure if it was going to level inverted or upright. Obviously it does whatever is closer. I tested it some more and the guys at the club had teased me about doing a 45 degree fall out of sky and save it. So I thought ahh screw it and went high and just did my first death spiral not 100% even being ready to catch the heli trusting the hc3sx. Flipped the switch just over the trees it levels inverted perfectly and gently climbs out and I keep flying. Now this is why I wanted this system over others it really does excel in the bailout. And it flys nicer than the beastx unit in Rigid too. I fly inverted a lot and am learning 3d and after doing $350 damage to my trex 500 last month I'm getting a couple more of these units for that heli and my 550 too they will pay for themselves in time no doubt and let me keep pushing my limits.

Hc3sX was not easy to dial in it was a real pain in the butt Took 3 weeks but the final result is awesome. The horizontal mode is quite impressive sure puts training wheels onto the heli for new pilots.

Lol , I had all the same poo hoo's down my local club, but now that they have seen it in action and understand better what the unit can now do, there are 7 units on order for other people down the club, the helicommand really is the HOT topic at the moment.

It can be a bit of a pain to dial in, but once you have done it once, it's now easy, It was super easy to get dialed in on my 500 but it took me longer on my 450 ..

Thanks to F1 Rocket (Danny) i will always use this procedure in the future .. It was really EASY ..

On the Rigid page set the Initial response to 3 and the elevator filter to 2

It is not recommended to fly in the horizon mode until the machine is trimmed and the head gain set correctly. For this is it much easier to keep the aux channel assigned to control the head gain.

This allows quick head gain adjustments from the TX. The trimming sequence is:

Set the head and tail gain to 50% as shown on the Diagnose page. Hover the machine in the Rigid mode and manually adjust the swash plate links for a drift free hover. If the machine drifts forward or back check the CG before you adjust the links Raise the tail and head gains until the machine starts to oscillate after a sharp stick input, then lower the gains approx 10%. Read the resulting head gain on the Diagnose page and transfer this setting to the head gyro default gain slider on the Rigid page.

After the above is set you can go to the Horizon page and reassign the aux channel to control the Horizon modes.

However, a good starting point is to download : Preset-Files for the HC3-X

http://www.helicommand.com/index.php...mid=97&lang=en

IMPORTANT : If you do USE a PRESET FILE FOLLOW THIS CAREFULLY >

When using these preset files, it is recommended to start with a head gyro gain (sensitivity) of 50%, doing the fine tuning from this start value, lowering or raising the gain. In first instance, these preset files are meant to be loaded and written in the [Tail Gyro] and [RIGID] menus ONLY.. SO make sure your NOT in the ALL menu when you load the file.

It does not matter that the files are for HC3-Xtreme it's the same thing as it's only loading in the tail and head gyro settings.

I have a windy flying field, and almost never no wind. I can't do the hover in Rigid mode and check for oscillation as the machine is constantly on the move by the wind. Is there any other measurement to setup Rigid mode with this condition? Currently I just put the head gain at 70%. It flies well in horizon mode, but since wind always blew the heli I don't really know whether the setup is optimal or not.

[F1 Rocket]

The machine will feel more and more locked in the higher the head gain. You will know when the head gain is too high. The machine will start to rapidly oscillate (shake) side to side. This being said don't fixate on a number. It will be different depending on the machine and personal taste of the pilot. If you are comfortable with the way the machine is flying at the head gain setting you are at, go fly and have fun.

That's the problem Danny, the heli always shake side to side by the wind blowing it to one side and me giving counter input

So you're saying the head gain is something of preference, it won't give me any unexpected trouble?

You will know for sure when the gain is to high, get in to a decent hover and give quick collective inputs. The head will shake rather violently side to side when gain is to high, then reduce it around 10%.

[Tyler]

There is a very noticeable difference between wind blown and high gain setting oscillation. Think of it as rapid tail wag on the aileron channel. Don't let it spook you, though. You will still have control, but there will be very fast oscillation until you drop the gain a few points.

[pabbas]

Thanks for the input guys, I will try to check it again tomorrow.

You mean rescue mode with collective, or just self-levelling?
If you talk about rescue mode, then you MUST apply -100% for that. In any other case the collective pitch is not fully automated and depending on your stick position the heli may not climb enough to rescue it from a crash when close or fast towards ground.
On the positive channel side, for horizontal mode only, you can use whatever gain you like.

Yes I was just testing the bail out with collective at -50%. Read others say
-100% was to aggressive so set it at
-50% and it worked great. Was the end of the day so couldn't try -100% but will this weekend as I tune in my 2 new hc3sx's.

[Joachim HC]

Just that you do not get me wrong: I am always talking about the percentages in the Diagnose page!
So, when using rescue mode (negative signal in diagnose page), you MUST set -100%. For the rescue action it needs to be the fastest and fully collective overriding signal by the system, and this is -100%.
In positive signal range, only using the self-levelling (coaxial mode), you can use whatever percentage (gain) you like.
