I'm running a WR super mini BEC at 6.0 volts, i have solder two heavy gage servo style connecters right to the board, one pluged into the programing plug, one into the forth servo plug thats unused, that puts power input on both sides of the power rail and it stays right at 6.0 volt all the time.

very solid power all the time !

I just purchased a Gryphon HV ubec (good to 18s) and it has 2x rx style output leads. I'm using 2x Dsm2 Spektrum sats and will reg the voltage to 6v.

I just asked Danny where to plug the 2nd output power lead into (1st to battery/head4) and he told me that most of the hc3sx power bus is common except output 2. So for me that means I can either use the PC socket, or either of the two below it.

Cheers,
TomC

I was gonna use 2 1900mah 2s lipo's wired in parallel to double the capacity, I usually use an align 6v regulator

That is correct, I have seen it more than once now.

Output 2 does not have a common power bus and cannot be used for input power.

Voltage
I run mine on 5.4v all day no issues with this power level. Even if I am autorotating and the voltage drops to around 4.8v the unit still works fine.

I have now installed, HC 3SX onto my electric heli. I am flying on oldschool 35mhz futaba, this heli has had a faultless track record for many years and was totally overhaulded 10 hours ago.
Helicommand setup was very straightforward, with a few bits I had to check on, all transmitter mixes, subtrims etc are off. All helicommand trims are set to defaults, the helicopter being mechanically set to the Helicommand, this is a bit unnecessary but just thought I would keep it simple.
Helicopter has flybar and I am flying in Horizon flybar mode which I also boot up in.
Power supply is 5.2v from 3300mah li-po.
First flight was perfect, ie it does exactly what it says on the tin,
It holds the heli perfectly level.
In forward flight there is no hint of the HCs presence, but let go of the cyclic stick and the heli returns to perfectly level no matter what angle of turn or attitude you are in. Very impressive.

Vibration testing to establish HCs robustness to a out of tune heli
.

Having completed the first 10 min flight test without event, I went on to UNBALANCE the helicopter by adding weight to one of the blades.
I progessively added more weight to the blade to monitor the Helicommands reaction to it.....It remained steady and perfectly mannered. So bad was the out of ballance forces at one point I felt that a 5 min flight was all I was prepared to do for fear of damaging my heli. Headspeed was also varied from 1550-1100rpm during these tests. Again Helicommand was faultless.

Next up was a Ground Resonance Test, this again was provoked by an out of ballance heli on a concrete surface, again after about 20 seconds of resonance in burts of 2-5seconds max the helicommand HC 3SX did nothing and was quite happy.

My own personal opinion is that this unit after a short period of testing seems to be very tolerant of a truely awfull heli that's Vibrating its Nuts Off!! That's technical speak folks!
So, so far so good, I have retuned the heli to it's proper in ballance set up and will now embark on some saturation testing.

will report back, Bell Bloke

Please note I am no kind of expert on this, so if anyone has any advice for me here please pipe up..

Hi Bell Bloke

I flight tested my 700 mechs for my Huey UH-1N yesterday with the scale flapping hinge head and extended-lifted TR, yesterday and had the same experience. I have mine set up so that on the Gear switch 1 = Rigid, 0 = Horiz and Trainer = Acro w/Pitch (Bailout). It lifted off perfectly in 1, then flew steady as a rock, very scale-like, in Horiz., then I tested bailout, set with about 3 deg. of change, and it just lifts right out of trouble. Amazing. I've also got the same set up on my aerial photo heli and its steady as a rock. Love it. I have MB and they're great FBL devices, but the HC3SX is in a different league. It does more. Thanks for your report.

Use the 3M or scotch (I forgot) grey tape with red backing you can find in Walmart
Joachim HC so do you agree that this tape is better than the tape that comes with the unit, am i getting this right ?
NO way, I will not be able to agree to something we did never test.
Which does not mean that this is a fact maybe on Raja's machine. But in general, from me as official support I will recommend using the supplied tapes. But again, ss I said, "in general" !! Not speaking about the one or other heli which in fact may work better with a third tape....from Walmart ;-)

Another question for the gurus.
Is it allowable to mount the HC3SX vertically on the front of the mechanics? that is with the servo leads facing forwards.
This is for a scale application and would be the ideal location for the unit.
Thanks for the support, Raja...but sorry.... NO is the correct answer !!! As only mounting on side frames is featured by the unit, not vertical with the soecket facing front or rear, only left or right.
And yes, Raja ;-) in all 90° possibilities: socket side (the side is the important difference!) facing front, rear, up or down when mounted vertically on a side frame.

Hope this was not too weired....let me know :-)

On HC website, it indicates satellites used should be at a minimum of 5.5v. If it falls under that is signal lost?
No, not lost at once. But the quality of the signals my be reduced, so we recommend this. With almost all BECs or batteries, this is no issue at all these days. Only a 4-cell NiCd or NiMH should not be used.

Fyi: you can use any of the servo sockets, as well as PC, S.BUS (sum signal) receiver and ESC output sockets. They all have the same power bus running through. And in case noone is available as you run 5 servos, S.BUS and ESC/BEC and want to keep the PC socket available at any time, well, simply use a Y-cable on any of those ports. So you are all more than flexible in the way how to get power to your HC ;-)

Oooh sorry
I knew you could mount it vertical just looked at the software again and see vertical L. anr R. which is left or right side of the frames only.

My mistake apoligize I didn't remember the L. and R. in the software.

Thanks Raja....
And: If all the answers all of you guys give in here were always 100% correct......I could loose my job :-)
How did one (crazy) guy tell me a short time ago (one of the nicest presents I got for Christmas): "I seem to be a guy only being employeed by my boss cause I can type" ....and he would like me to forward him to someone in here who knows about the HeliCommand systems :-)))))

This being said...have a great day folks....I am out of here for today :-)

Recently
I just realized that when you run s.bus to HC then all your cyclic servos are powered with 1 lead coming from the sbus cable from the receiver.

I put a 2nd sbus cable from a free port in the receiver to the helicommand throttle crossover port to double the wire current capability. Was not sure if the signal from the receiver would mess anything up so I pulled the siginal end of the wire out of the helicommand side and folded it back.

Was that the right thing to do?

OR, should I put the power cable into helicommand somewhere instead of the receiver and have the sbus cable carry power back to the RX where the speed controller is plugged in?

Thanks Joachim. I now know Spektrum satellites will reset at 3.6 volts. The satellites can operate sufficiently with 5.2 volts.

wow sorry ! when i read this......
They got Walmart in Germany?

Well...I thought about importing the tape....but...laugh or not, yes, we do have Walmart here. They made it across the ocean ;-)
you talked about "importing the tape" it made it seem like you really like it ?

thats why i asked ! the "NO way" was unnecessary when a simple no would do.......

Yes, always to the HeliCommand first then from HeliCommand to RX or from the power source to both the HeliCommand and the RX at the same time.
where the speed controller is plugged in?
although you can bring power into the HeliCommand though the ESC plug you would have to have just the one signal wire from the ESC and two wires from the power source all in one plug.

For power into the HeliCommand it would be best two use one of the following possibilities:

a) Battery connection / head 4 (in case no 4th head servo is used).
b) Programming connection (in case the PC adaptor is not connected; for programming the supply via receiver is ok).
c) In case of supply from a BEC controller, route a parallel supply cable (e.g. Y-cable) to either battery or programming connection
of the FBL system. This connection must not possess a signal line, i.e. the third pole may have to be cut.
d) For using only the tail gyro of the FBL system, you can either do a setup with deactivated head gyro (still using the internal mixer),
or only connect the tail gyro cables, plus one of the three-wired connectors (aileron or elevator input) only for supplying the receiver
with power from the FBL system, connecting it to any vacant socket of the receiver; preferably with disconnected signal-wire.

So... If using a separate spektrum/JR rx, I run power to the RX, then back. To the rx? How? With a servo extension? Is there a " power output" slot on the unit? Greg
