I'm calibrating the radio through QGroundControl, but it gets stuck every time I get to a point in the program where it asks me to move the left stick all the way up. It doesn't seem to register. Left/right/up/down on the right stick work, and left/right on the left stick work, but up/down on this stick doesn't work. I tried Mode 1 and Mode 2.
With the positions that work, I can feel resistance against the stick, like I'm pushing against a spring, and when I let go it returns back to the center. When I move the left stick up and down, I feel no resistance and I have to move it back manually. This tells me that there is some hardware problem with how the stick is connected.
Is this something user serviceable? If I unscrew the back of the DXe, will it be reasonably easy to fix this stick, or should I return this DXe for repair/replacement?
Thank you for contacting Intel Customer Support.
Are you following this guide?
Could you watch the video below and let me know if you see a different behavior?
Hey, thanks for the response.
I am seeing a different behavior than the video. When the person in the video moves the throttle up and down, channel 3 on the channel monitor moves up and down in response. When I move the throttle up and down, there is no response on my channel monitor.
The channel monitor responds to left-right movement on the left stick, and it responds correctly to all four directions on the right stick.
I replaced the Spectrum DXe with a new one, and I'm still seeing this same issue.
We've also experienced this behaviour at one point.
It's not necessarily a hardware issue.
You can try reflashing the firmware for the flight controller and make sure it's up to date.
What OS are you running on Aero?
Have you installed the PX4 firmware or Ardupilot?
Thank you for your reply.
What device are you running Qgroundcontrol from to do the calibration?
I would advice you to change the host computer/ device you run Qgroundcontrol from.
Try a different computer or a phone/tablet.
You can also install Qgroundcontrol directly on the Aero and run it from there if you have Ubuntu installed.
Do you have any more ideas?
I can't arm the motors with the DXe by holding the throttle in the bottom right position, and I suspect it's because the drone isn't receiving the up/down position of the throttle stick. I can make the drone take off and land by using QGroundControl running on an Android tablet, but I can't do anything with the DXe.
I think you need to make sure that you set the lower right switch to "arm" and set the rate to "high" on the controller.

Additionally, it is important to know that the throttle on the left stick intentionally doesn't have springs and that it's designed as such, not an issue with the controller.
I hope this helps.
I'm following those steps exactly. I don't believe the drone is receiving input from the throttle control. The radio calibration procedure in QGroundControl gets stuck on the step where it tells me to move the throttle up, because it can't tell that I am moving the throttle. All of the other stick movements (left/right and up/down on the right stick, and left/right on the left stick, but not up/down on the left stick) are reflected in the slider widgets in the QGroundControl app.
The orange led on the receiver on the bottom of the drone and the orange led on the transmitter are both solid, which I assume means they are paired correctly.
Can you please try to follow the steps in the following link:

The orange LED on the remote control receiver is blinking:
Let me know if this helps.
I did nothing differently, but I tested again today and the throttle control is now working in the calibration screen, so I am now able to calibrate the DXe correctly.
However, I am still unable to arm with the DXe. I have all of the switches in the forward (away) position -- flight mode=0, motor/throttle=arm, aux=0, flap=09, and rate=hi -- and I held the throttle/yaw stick down and to the right for a full minute, but the motors would not arm. I double-checked to ensure that the orange led on the bottom of the drone was solid (not blinking) and it was solid.
