I have a radio already setup with lots of mixes and throttle is on channel 1.
I plugged it to my pixhawk via SBUS, so I can't move channels around by swapping cables.
I told APM that throttle is channel with RCMAP_THROTTLE set to 1.
However when I go to radio calibration in mission planner (windows) or APM planner (linux) both show throttle moving 'roll' and not 'throttle' (and the other channels being similarly mismapped).
Is it a known problem that the radio calibration ignores channel remappings?
Thanks,
Marc

The radio calibration screen will always show the throttle control, for example, as the throttle raidio control indicator.
If you look at the failsafe setting view, you can see each output of each channel without translation. Maybe that will help see what each channel is doing?
you can pick up this daily build http://firmware.diydrones.com/Tools/APMPlanner/daily/2014-08-09/ and it should have the correction to the Radio Calibration view. If you can test that, it would be great.
Thanks for reporting the issue. It's now fixed hopefully. It's not the easiest thing to configure and test (well time consuming) Others will benefit from this like Gary who use JR and cannot reorder channel outputs. I assume you have a Taranis (or OpenTX/er9X compatible product which allows changing the channel ordering)
@Gary, if you want help to make it work, pm me, as I'm sure I can make it work for you.
@bill: you are correct, I have a Taranis. Changing channels was easy, but after I spent a whole day setting up careful mixes and 30 functions to do fancy stuff, changing the channels then was a pain in the butt :)
I just went out for my first flight with my Cularis Glider after installing the pixhawk, and everything worked well, or at least well enough :)
I have just seen this thread update, thanks for the kind offer Bill. I'm downloading the beta right now and will confuse myself when I get up in the morning. Most splendid! Thanks once again.
I wanted to use the opportunity to thank you for your fine work on apmplanner. I think the only thing it misses over MP is not showing the full help for settings when you edit them (like knowing which numbers you can feed to RC5_FUNCTION and what they mean). Given that I can look them up in http://plane.ardupilot.com/wiki/arduplane-parameters/, it's not a huge deal and it saves me from having to deal with windows/virtualbox.
So thank you for your work (and your colleagues')
To see the function descriptions for the RC channel you can view them in the Standard Params View or the Advanced Param view. You can search for the relevant ones at the top. For RC5_FUNCTION you will see a combobox with the values you can set.
Hi Bill, thanks for the tip. Indeed going in standard params showed me the info for RC5_FUNCTION
but it would still be good to have the full non truncated description in full parameters.
As another example: ARMING_CHECK is a bitfield and your method doesn't work to set it, I need to read the description, add up the bits and set that by hand. I'm totally fine with that, but without the full description available in full parameter list, like it is in MP, it's not easy to do and not possible on the field if you have no internet to look up the web page.
Hi Bill, I very much appreciate that you fixed that so quickly, had I known you were doing it, I would have waited before repgrogramming everything to move back to AETR.
Unfortunately, I did do that, and it took 2H of work (7 channels, lots of mixes, failsafe settings on both the controller and APM side), and to be honest, I'm not really looking forward to spending another 2H on this or 4H if I need to revert (very busy with the final plane build and testing on a deadline).
I'm not sure if there is an easy way to test this with a simple 4 channel model without mixes you have lying around, I apologize for not being able to do this easily here.
The channels are mapped one to one as expected, that works fine, it's just that I don't know if APM will try to use my throttle as a rudder.
