Hi

I have a Power box Champion RRS in my F4 that I plan to maiden this weekend. Everything is working fine but I have a bug that would like to clear out:

The Powerbox is working with 2700mAh lipo packs a 2 Futaba 6014 receivers. All surfaces are connected to the power box and are working independently, but the flap servos that use the same channel. I have then match the flap throws in that channel with the powerbox. everything's perfect but;

If I conncet the power box with pack II and then pack I, is ok. If I connect the PB the other way round, all servos, specially flaps start to jitter violently.[&:]

With both packs connected, if I disconnect either battery, will work fine

Any one as experience this? Have I something to worry about?

Also, seems there isn't a contact form in PB website to make the question[]

Regards

Nuno

Hi

Does anyone as an e-mail contact to report this issue to PowerBox. No e-mail contact in their web

Have you tried swapping the battery connections around on the PB unit so that the batteries are plugged into the opposite socket?

Nuno it sounds like one of your two receivers is left on HS mode.

Cross check that both are in normal mode (read the futaba manual came with your receivers)try again and let me know

Hi

Thanks for your replies.

Dave - Yes I did, but same thing happens in inverted sequence.

George - Ok, I'ill try that. But shouldn't the Power box work properly both in HS and normal mode, with the 6014 rx?

Hi Nuno!

I found their e-mail on a few pages of their webside, just follow this link and send them a mail:

Emmerich and Richard are always quick on replys and as they do their own development, they do know the products pretty well

Best regards,

Are both your receivers binded? Once a friend had a similar problem and it was solved when he found out one of the receiver wasn´t binded

Not sure if this makes sense but I have got the "jitter" in mine occasionally. It seemed like it had more to do with the batteries being at full charge. After I would fly it the "jitter" would go away.
It usually would happen if I had just taken the batteries off the charger.


Hope this helps,
Billy

Hi

Both rxs are binded and working properly. Have to check the HS mode and discharge batteries

Hello Nuno

did the promblem was the HS mode?

Nhalyn

I can't be OK with the overcharged batteries, as the PB regulate the battery voltage to 5.9V or 7.4V (user setting) to the servos and always remain at 5V to receivers whatever the voltage is on the batteries.

Seem's most likely receiver one is in HS mode, as when pluging accu #2 fisrt it will be the receiver #2 that will work, and doing that it's ok. Pluging accu #1 first, the receiver #1 is working and the servos are jittering...


That cause me an other question : I've noticed on my PB Champion RRS that one receiver is linked to one battery. That mean if I lost one battery in flight (fail, empty, etc. [:'(]) I also lost the redundant receiver feature ? I was thinking this should be a normal stuff that a full redundant system should work with downgraded mode, for exemple :
- 1 battery lost, the other one fly the plane and there's still redundant receiver 1 and 2 that can fly the plane.
- 1 receiver lost (fail), the other one fly the plane and there's still redundant accus 1 and 2 that can fly the plane.

What's going on if by a very unprobable mystery I lost accu 1 and receiver 2 ??? [:@]
Probability says this should nearly never arrive, so this don't prevent me to sleep...

Not 7.4 but 7volt.


No even with one battery you have receiver reduntancy.




[8D]

Nhalyn

That's the response I was waiting for, but are you sure ???

I've done the test with mine, and when I disconnect the accu 1 with receiver 1 active, it immediately switch to the receiver 2. Now all switched on. When I disconnect the accu 2 with receiver 2 active, it immediately switch to receiver 1...

Surely if you unplug the "failsafe channel" from the selected receiver you can check this? It should switch to other rx if redundancy is on both rx's with one battery?

DelGatoGrande

My Feedback: (23)

exacly you can swich from one receiver to the other by just removing there fail safe extension and you can see your self

jetnuno

Hi

I had one rx in HS mode and the other was normal. I have put BOTH in HS mode and works perfectely now.

It as nothing to do with charge in batteries

Regards


Nuno

My Feedback: (23)

No you must put both to NORMAL. NOT to hs

Moerig

Does this mean that one has to give up one channel for failsafe or can the failsafe channel still be used for another function?

Nhalyn

Why ? If all servos are numerics and other accessories are ok with hs mode ?
For the present case it seems to work now with both in hs mode...

DelGatoGrande

My Feedback: (23)

One same channel from each receiver is used for the RRS .This channel can not be used for any other function.

DelGatoGrande

My Feedback: (23)

Futabas "HS" doesnt work with PowerBox.Simple as that...even the own matchbox from Futaba are not working with HS,

So you have two opinions,

First not use the HS mode

Second : the HS mode is only on the first 5 channels of the receivers, so you can take the match channels from the PowerBox on the channels over the first 5, by the 6014 you have 14 channels and only the first 5 have the HS mode. From channel 6 – 14 the match channels are working.

Nhalyn

You are completely right George ! I have'nt think it this way before... Thanks...
