CC3D spektrum problem
« on: June 05, 2020, 01:36:39 pm »
Hi All,

I am new to this and have a problem.
My racer is:
https://acme-online.de/en/rc-models/multicopter/zoopa-q-crosswave-290.html

recently its original radio broke down and I thought to bind it to my DX7 G2.
Bought the new spektrum satelite:
https://www.spektrumrc.com/Products/Default.aspx?ProdID=SPM4650

Made a cable for it and tried to bind, nothing:(
After few attempts I flashed the FC to betaflight and it broke down.

Now I have this FC:
https://www.banggood.com/CC3D-Flight-Controller-Openpilot-Copter-Control-Module-p-1218849.html?rmmds=search&cur_warehouse=CN

but the problem is the same, not binding.
I have tried with a normal spektrum satelite and nothing too.
It is like the board does not take the sat as a receiver besides the parameters are saved.

Please help:)

I do not own any Spektrum, but I think I recall that (for LibrePilot at least) to use a Spektrum satellite by itself, you must bind it using a full Spektrum receiver.

I Googled
  bind Spektrum satellite
and got some hits.  You already tried some of those I guess?

Of course, once you bind it using say a BetaFlight procedure, you can use it with any flight software; like e.g. LibrePilot.

I have tried that and nothing:(
This spektrum satelite for quadro has a button to bunding and it is already connected to my radio.
It is like the FC does not see the receiver.
Of course I set up the channels.

I use spectrum satellite receivers in three hells and it works fine with librepilot and with several boards, Atom, Nano, Revo.
I don't think is has much to do with the FC you are using.
Make sure you successfully bind the transmitter to the satellite.
Maybe this can help (there are other similar videos)


When binding is done the settings for radio channel type in GCS - configuration - remote control input, should be 'DSM (with the port you are using)' for example DSM (FlexiPort).
If there is no input after that, then I would check the cables for tx and rx are not switched.

The satelite is bound.
No activity of receiver.

Try change the setting from DSM (Flexiport) to DSM (Main port), in
the settings for radio channel type in GCS

Ok I changed the port but it did nothing still message receiver no activity:(
However I did some tests and I think the problem is with the connection to satrelite because I bound it thrue the brain fbl and it has stable connection but when I switch to the cable to FC it blinking- no connection.

I have this cable which was original to the previous receiver. The wires are ok I think. I checked the pins order with board.
It is like the signal between sattelite and Fc is missing.

Are you aware that Spektrum satellite rx needs 3.3V and not 5V?

All ports on normal LP FC output the same voltage you power the FC with.  Usually 5V.  And only when the flight battery is plugged in to the ESC/BEC.  USB power does not power the FC ports.

That cable probably needs a 3.3V regulator added in the middle (cut the red wire in the middle of the cable) with regulator input coming from the 4 pin red wire, 3.3V regulator output going to the 3 pin red wire, and common connected to the black wire.

I had forgotten about that wiki page.
The instructions their actually say you need to bind it using the Flexi port and @LechuW is using Main port.

No. The satelite is bound by heli fbl no by FC. I will check the voltage. Thanks.

Hmm I have checked my sattelite:


This one is for drones and it works with dx7 connected to the FC by main port but with the same issue receiver no activity.

It worked!

But it would be too easy of course if everything work correctly:(
The libre pilot does not see the yaw stick movement:(
Any ideas please?

Only yaw is broken?

From memory, go to Input page, and with transmitter on and flight battery installed so that receiver is powered, wiggle yaw stick and look at "receiver activity" box in upper right of Input page.  It will tell you if it works, which channel the yaw is on.  On this same page, set the yaw to use that.  Also make sure that type, number, min, neutral, max, and reversed are all reasonable for yaw.  Wiggle other sticks to see that they also show up in the activity box.

Or you can run the transmitter wizard from that page...  Maybe you accidentally skipped a step for yaw the first time you ran transmitter wizard.

Something is strange. When I move yaw there is activity on channel 4 but the movement is registered in libre as throttle.
