CC HV85 issues on my H550

[probe3]

Hello everyone,

Ran into a brick wall during my build...While setting up the HV85 ESC with my Medusa 6v BEC, the speed controller will not arm. I took a few photos to explain:

While connected with the BEC, I can't arm the ESC. I checked my low input endpoints (changing these values does nothing) also checked to see if Channel 3 was reversed, again changing the value did nothing. Still get a nonstop blinking red LED on the HV85. The picture doesn't show the battery connected, but when I plug the ESC to the USB, I then plug in the 6s battery.

My other question is setting up the ESC via CC USB Link. Here are my current settings, do these seem correct for the V2 Gaui short staff motor ?

Thanks a bunch !

The speedo is not reading your throttle endpoint properly.

1. Set the speedo to "Heli Fixed Endpoints"

2. Set your throttle Low and High Endpoints to 50% each way.

3. Plug in your speedo to your battery with the reciver powered up.

4. Move your throttle stick to the low position.

5. Drop your throttle low endpoint until you hear the speedo arm.

6. Unplug your speedo and move the throttle stick to mid point.

7. Plug the speedo in again.

8. Go to full throttle.

9. Raise the throttle high end point until the LED on the speedo goes solid red.

10. Unplug your speedo.

Next time you power up with your throttle stick down your speedo will arm and oprate normally.

Everything else looks good.

You can also watch the Finless vid :D
Lot's of good info

Thanks for the Step by step Adrian !!!

While going down the list I can't get past number 5, the ESC won't arm. I shot a short video to show you what is happening.

Seems like no signal coming in

What throttle curve are you using in the tx? 0 - 100?

Maurice

[probe3]

Hey Maurice, my Throttle Curve on the TX is:

Normal 0,85,85,85,85
Idle 1/2: 95,95,95,95,95

i just tried hooking up my hv110 without the red and black wire connected to the receiver like you have in your second picture and got the same results as you get. when i plugged them back in all was well again.

Probe3.
Thottlehold is off?

[dutch_anykey]

For seting the end points the curve should be set like 0 -50-100 in normal mode. Else it wont see the real endpoints.
But strange though it should see the lower endpoint anyway if set to 0.
Like Patrick says throttle hold is of? (Idle switch perhaps)

Probe:
Did you watch the video's from Bob b.t.w.?
I watched them and had no problem at all when my Esc arrived last friday. It was like i knew this ESC already :D

You only need to cut the red wire if you dont want to use the Bec on the ESC. But you guys have the HV versions? They come without bec anyway isnt it? Then you don't need to cut anything. The black wire and signal wire should always be used. Only using the signal wire without the 0 or blackwire isnt right. The siganl needs a reference to zero voltage. That's where the blackwire for.

Probe 3, I got the same problem when I first use the cc 85HV. The ESC can arm if you trim the throttle down a bit by the slider switch.

[Finless]

OK first you need to set your throttle normal curve to 0,25,50,75,100.
The ESC needs to see a normal throttle movement.

THen either follow my video or Adrians instructions
BUT Adrian has something reversed.
Set you HIGH throttle first then do your low throttle. Doingit the other way around you might spool up as your low throttle ARMED the ESC.

But you problem is what folks are telling you here. You need heli fixed endpoint in the ESC, you need a linear throttle curve, then you need to set your high throttle end point and low throttle end point per my vid or Adrians instructions above.

Hey guys,

Thanks a mil for all the good info ! Yes, I watched Bobs HV85 setup videos plenty of times. I think the MAJOR problem at the moment is running the Medusa BEC along with the ESC.

I just tried connecting the positive of the bec and using the negative from the ESC. Hoping the ESC will read it's own negative zero. This didn't work because the Rx needs the pos and neg from the BEC to power on.

So my next question is...Do I connect the neg wires together from the BEC and ESC, then just use the pos from the BEC ? and connect all that to the Rx ?

Once I get this part down, where the Rx is getting power and sending my Tx inputs into the ESC , the rest should be easy as pie !

[dutch_anykey]

Yep,

put the neg. wires together.

Maurice

[probe3]

Sweet Jeebus it worked ! I first tried just connecting the black wires together but still no go. So I said screw it and additionally connected both pos wires together and finally it worked ! The endpoints worked and the ESC arms!

Now all I am waiting for is my tail servo to arrive (tomorrow) and I'm ready to tack headspeed then switch back to governor mode.

Thanks everyone for all your help! :cheers

Awesome work guys helping Probe3!

Glad you got it sorted Mark!

Bob

[probe3]

Yes ! Thanks everyone :)

So I'm about to go to the local park and give this heli a test run ! I do have ONE question about the ESC before I go. When I switched back to Heli Governor High and set Normal to 72% and Idle Up to 86%...the ESC LED turns on when the motor reaches full speed. Is this correct ? The ESC light turns ON when motor reaches target headspeed ?

Thx !

Probe 3,

I just read about the red wire. even tough there's no BEC in the HV version it still needs the red wire on the HV version. The esc actually is taking power from the rx/external bec to power the optic isolators in the ESC. Didn't know that as well

As for the lights.
Is it steady on? or flickering.

The red light indicates that govorner process has reached 100% throttle. This shouldnt be while hoovering i think. I guess it's all right if it blinks a few times in heavy manouvres. (Finless, correct me if i'm wrong)

Maurice

[probe3]

It's a steady on....?

Speaking of this..I have a problem with my ESC and BEC on the Hurricane. I did a work around but I am not sure it is a good work-around.

I have the stock 50a ESC and I wanted to use a BEC that is powered directly from the main batteries. A friend gave me a SportBEC from Dimension Engineering and I set it to 5volts so I would not need a step-down for the tail servo.

As per the instructions.

I connected the throttle wire from the ESC to the throttle input on the BEC. I then connected the throttle wire from the BEC directly to the throttle channel on my AR7000 receiver. And paralleled the power wires on the BEC to the ESC main power wires.

My problem is, I have no throttle control at all when connected this way. All other servos work, the receiver is powered and working. Finally I removed the throttle wire from the ESC and connected it direclty to the throttle channel on the receiver and Bingo, the throttle works fine now. So for some reason the BEC is not passing the throttle signal through it.

Any thoughts on my by-pass ? Should I investage further on why its not working as per the manual ?

Thanks

Tom
