Title: hello and a little help needed
Post by: malloch on January 01, 2017, 17:49:51
Hi to all.

I got a 250 drone kit for Christmas and have spent the last week putting it together. 

(https://s24.postimg.org/yxqpawsrl/20170101_174104_1.jpg) (https://postimg.org/image/yxqpawsrl/)


I have now calibrated my motors on Clean flight and am now trying to set up the receiver but having no joy.   I have plugged in all the connections from my naze32 to the reciever in the correct order but when on Clean flight I have nothing showing.  The little red light on the receiver is solid and not blinking so from the videos that i have watched it means it bound? Correct? Im using a flysky fs-t6 controller.

I am learning as i go but seem to have reached a point where i am lost.

Any help would be great.

Thanks

No flysky expert but
Yeah guessing it is not bound
You would probably be better getting a ppm or ibus reciever rather than that PWM one too

i had a signal for a short while on one channel but then followed the instructions on one video and managed to loose that and now have nothing.  The receiver I am pretty sure is a ppm connection as this is the underside of my naze (picture taken from banggood)

i have gone over all the connections and everything seems to be in order so can only guess its me not doing the software right but dont know where to start on this bit.

Hi Malloch
on the flysky you have a receiver that will do PPM then select PPM at the tx but I don';t think the FlySky T6 can use PPM (happy to be corrected).
Set it up PWM first to check you can get a bit further, PWM less responsive but it would at least get you some airtime.

To bind you probably need to short the RX bind connector, power on, turn the TX on with the bind button held down (assuming there is one) then power off the RX, remove the bind plug, power off the TX and back on then power on the RX.
I';m sure there are videos that explain that better than I just did.

I';ve managed to get it to do something.  It shows that my yaw is coming through on aux 1. I have no throttle and nothing for roll or pitch at all

Are you sure the FC is in PWM mode, that TX and RX will only support PWM.

Ok so here is your problem, and powernumpty is spot on as usual.

Your radio reciever does not do ppm or serial protocols.
It puts out one channel on each pin. (1-6)

(PPM and serial protocols use one pin (and therefor 1 wire) for all the channels)

This type of protocol is PWM (and is quite old)

To get it to work you need to connect each of the signal pins to the corresponding pad on the naze (the one you highlighted is for channel 1, you have connected that to channel 1 on the radio reciever so that channel is working, you need to connect 2 to 2 etc, up to at least 4 to 4 but probably best to do all 6)

You don';t need to connect all the ground and voltage pins, you only need one set of those, which you already have, just the signal pins
Title: Re: hello and a little help needed
Post by: malloch on January 01, 2017, 22:21:04
I had the first 4 plugged in and could only get one response. I then plugged in 5 and 6 and got nothing extra. I then  swapped all pins from 1-6 to 6-1 and now have all but throttle. They are coming through on aux channels though.

Connect 1 to 1, 2 to 2 etc
If one channel isn';t working you either have a broken cable or a dodgy solder joint

Connect to cleanflight configurator and on the reciever tab you can see what stick does what. 1-4 should always be the 4 stick moves, they should match the channel map
Title: Re: hello and a little help needed
Post by: malloch on January 01, 2017, 22:43:26
Will swap all the wires back round on the receiver after work tomorrow and start again. Getting too frustrated with it now.

On cleanflight I can see that on the positions that they are in I have 3 responses but they are not the throttle label that they should be but aux 1,2 and 4.

Sorry for being a pain. It';s probably something simple that I';m getting wrong. I';m quite happy either the making and taking apart  (being a mechanic it';s how my mind works) I just struggle on the programming side of it

Right I think I am there now. Took all the connections off the receiver and started again.

Just got to put the LEDs on the underside of the arms and connect up to the PDB and put the last bits of the frame together then it';s maiden flight

Fingers crossed will be up in the air in the next couple of days

Post by: malloch on January 04, 2017, 19:07:14
So I have one lit up drone that spins it motors

After checking the correct rotation on cleanflight earlier in the build it now turns out that I have 3 spinning the wrong direction. As I';ve shrink wrapped my esc';s and tidied all my cables up, is there a way that I can reverse the motor without having to desolder and cut my shrink wrap off. I saw that it can be done on cleanflight but have no idea where the options for that are.

For a first ever drone build I';m well happy with the way it looks. Just frustrated that at the last step of getting it up in the air I have to take 5 steps back.

I';m trying to upload a pic but keeps crashing out

Looks well built.

Power cable look a little long and may get caught up in the props .. But a few tywraps should sort that

You may be able to swap the rotation in software depending on the ESCs and the firmware they use.

What you got?
Title: Re: hello and a little help needed
Post by: Cheredanine on January 04, 2017, 20:18:35
As per Fletch.
If you have blheli escs you should be able to download blhelisuite, the. You can connect to the escs through the USB port on the flight controller and change the motor directions
Title: Re: hello and a little help needed
Post by: malloch on January 04, 2017, 20:54:03
How will I know if they are blheli?

Will attend to the power cable before I take it out properly just to be on the safe side

Just me but personally I would just re solder the motor wires so I could get in to the air ....
Then figure out if I had belheli esc and how to reverse the motors ..
Its easy when you have all the software on your computer and now how to use it
But fried my brain at first...

They are emax Simon series 12a ... they are not simple to flash ....

I did a post on flashing them a few years ago ... you';ll need an arduino uno

Just switch wires!
Title: Re: hello and a little help needed
Post by: Fletch on January 04, 2017, 21:31:43
They use a bastardised version of blheli... not Simonk as you may expect.

They can be flashed but it';s cheaper and easier to buy a new set of escs in the future once you start to uograde

Depends what motor/prop/cell count you are running (this governs how much power they will draw and therefore the amp rating of the escs, but spedix as a brand, something like this:
https://www.electricwingman.com/searchresults.aspx?q=Spedix (https://www.electricwingman.com/searchresults.aspx?q=Spedix)

Edit eep, are you powering the flight cintrolller from the escs? If so you will also need a 5v reg/bec
Title: Re: hello and a little help needed
Post by: malloch on January 10, 2017, 14:46:10
running on 3 cell. I have very basic set up as it wasn';t  an expensive kit.  The motors are "TAROT 2300KV".  You guys (and maybe gals as can never tell by user name) said that the ones that I have killed were 12A so jumping up to a 20A wouldn';t be a problem? 

The spedix ones have the 2 wires to the esc dont they? That means I would need to put a 5v feed from the PDB to the Naze to power them?
Title: Re: hello and a little help needed
Post by: Cheredanine on January 10, 2017, 14:49:19
Yes and yes
20amp will be fine
And you would need to put a 5v supply there to the fc

And so the cycle of upgrading starts!  Lol

As you are upgrading ESCs, you be as well put in a PDB with a 5v regulator onboard it ... Or pick a flight controller that accepts full battery input

These ESCs look exactly the same the armattan ESCs and they are good

So the new esc are here and managed to get some time this afternoon to get the wired in.

Now before I plug my battery in and blow more things up, what are my next steps? I guess that I will have to effectively start again and wipe the fc and start again?

Oh and I shortened the battery wire on recommendation from someone plus some red cable because I can

Some of the order is interchangeable but:

1.  Update the firmware on the escs (blheli suite, you should be able to do it through the flight controller)
(That first step could be left off or could be done last)
2. Check the motors are spinning the correct direction - if they are not reverse the direction as required in blheli suite
3. Calibrate you escs in configurator

Off you go, no need to change anything on he fc, the escs will auto detect the protocol

Ps, a bit concerned by your picture, make sure the bottom pads of the escs where the motor wires are soldered can not touch the frame, carbon is conductive, a short across there would not go well

just looked and at least 3mm clear of the frame. the bottom of the esc and the shink wrap holds it off. thanks for that tip though, hope not to blow these ones up


plugged into cleanflight, fc lit up blue and flashing orange.  no beeping and the motors didnt twitch like they did before? normal?
