Okay, Iā€™ve done that and Iā€™m now in WinGUI and Iā€™ve calibrated Acc but my Transmitter doesnā€™t seem to be connected to the receiver. When I turn the transmitter on none of the motors are working. Any ideas what Im doing wrong here?

Thanks

Please, make sure you did all the steps in the user manual as we will hit issues at each step if you donā€™t follow it. HERE
The motors will not spin unless you ā€œarmā€ your copter and will or will not turn at arming depending on the setting you selected in the FCT (Flight / Motor Stop).

24

I have been following the guide and everything seems fine up to section 2.5.2 but where it says ā€œYou should be able to make the signals move on each of the connectionsā€. I am not able to do this, how do I fix it?

Thanks,

Simon

Hi Simon,

How are you wired to the Receiver (picture)
Which system of transmitter & receiver are you using (picture)

:slight_smile:

26

Hi Eric,

I have wired the receiver the same as it is shown in the manual section 2.3.2. I have attached pics of the wiring to the receiver and a pic of the transmitter.

Thanks,

Simon

Note that the channel order might change since the user manual show a typical setup for the Hitec system.
However this should work even if the channels are not in the right order.

Whatā€™s the setting in the FCT for Receiver ?
It should be StandardPCM.

28

Eric,

In FCT my receiver was set to serialSumPPM, I will change it now to StandardPCM.

Do I also need to change this setting on my transmitter or should it change automatically? It says PPM on my transmitter currently also.

Thanks,

Simon

Hi Simon,

Your receiver is ā€œPPMā€ capable but i would stick with StandardPCM for now since it will be much harder to explain how to setup in PPM.
No change on the Transmitter side to do PPM out itā€™s a mode on the Receiver which involve pressing the switch to change mode. Donā€™t do it right now itā€™s in StandardPCM (default).

Eric,
Thank you for the DXe Transmitter advice. I removed the alkaline batteries from the transmitter, connected it to the PC with the USB cable and powered the transmitter from the PC. This then showed that the cable and device was connected. I was then able to change each setting to 120% in the channel setup. I could see no ā€˜saveā€™ option, so assume that it is still set at 120%.
So I now have the wiring setup as in an earlier image, have managed to flash the firmware successfully to the quadrino nano and have set the channels on the transmitter. I have tried using the transmitter to control the motors, but still no movement. A long time ago I tested each motor separately using the powered ESC and the transmitter / receiver and I was able to adjust the speed of each motor using the transmitter joystick, At this stage, there was no quadrino nano in the loop (at the time I was still having difficulties installing the quadrino FCT due to the local ISP blocking the flying Einstein FCT software). What do you think I am now missing or doing wrong to not be able to get some life out of my set-up? Thanks.

Make sure to use my file as it also cover the reversing of some channels.
Once the transmitter is setup, you can head to the WinGUI window and verify that you have signals from 1000 to 2000 on every channels. (make sure you donā€™t have any propellers on the copter)

If the above is confirmed, you need to ARM the copter prior to have any motor outputs to the ESCā€™s.
This is covered in the user manual as well.

Hi Eric,

Thanks for all you help so far, I think I have nearly everything sorted now. All my motors are arming fine now, however they are all spinning at different speeds and times. I have played about with the min throttle conditions in the FCT but this doesnā€™t seem to be changing anything. My rear left motor is spinning first and my front left is spinning last.

Any ideas of how to fix this?

Simon

33

Hi Simon,

When you test those RPM/Speeds are you on the ground looking at the propellers or you refer to the WinGUI motor outputs ?
Whatā€™s happening when you ā€œarmā€ the board and which setting is in FCT under ā€œOptions / Flight / Motor Stopā€ ?

34

Hi Eric,

Im testing with no props on so the drone is on the ground so I can see the motors and when they all start and stop but I can also see the values through WinGUI. When I arm the board nothing happens until I raise the throttle to 1040 then the rear left motor starts but the other three donā€™t, as I increase the throttle more the two right hand motors begin to turn and the last one to start is the front left.

In FCT under ā€œOptions / Flight / Motor Stopā€ the motor stop box is ticket.

Thanks,

Simon

35

Eric,
Thank you for the profile .srm file. Which ā€˜Modelsā€™ page do I import this on? There is the option to import a profile on the quadrino nano FCT software ā€˜Welcomeā€™ page, but it is looking for a config.h file and does not recognise the .srm file. I can find no ā€˜Modelsā€™ page on the WinGUI software. Thanks.
John

36

With that option selected (Motor Stop) the motor will now spin when you ā€œARMā€ the flight controller until you raise the throttle.
If they do not start all at the same time, raise the ā€œMin Throttleā€ a little in WinGUI (FC Config / Min Throttle) and save.

This file is for the Spektrum transmitter as explained.

37

Eric,
Thank you. I have imported your profile in the models page of the Spektrum software with the transmitter attached (and powered from the USB with batteries out I have flashed successfully the quadrino FCT. I have connected the system to WinGUI. I have gone through the calibration of the ACC and MAG and the Flight deck images change when I rotate or roll the copter around. With the transmitter armed, the Flight Control shows Thrust, Pitc,h Roll and Yaw values changing up and down when I use the transmitter joysticks, but the motors are not doing anything. What have I missed now?
John

38

Eric,
You will be amazed to hear that I have managed to get the 4 motors turning at long last! I had to dismantle to calibrate the ESCs with the transmitter, then armed the copter and the motors all spanā€¦ Off to try fitting propellers nowā€¦ Many thanks.
John

Make sure you have both the motor rotation & propeller right prior to lift.
Also, you can set the ā€œHORIZONā€ mode if you want level stabilization.

Hi Eric,

I have changed my min throttle to 1150 and the motors seem to be starting and stopping at the same time. But in WinGUI the readings for each motor are still different. I assume these readings should all be identical, and to make them identical do I just keep increasing the min throttle?

Thanks

Simon
