APM servo reversing

Posted by Fred Briggs on October 23, 2010 at 9:40am
I am setting up a APM with a F27 Stryker that uses elevons. I am working with code revision APM 1.0 Public Beta. I have everything working well in manual mode and I used the reverse dip switches to get the controls to react properly to the transmitter in stabilized mode. The issue I have is that in stabilized mode when I pitch the APM reacts with one elevon up and the other one down which is wrong. When I roll the plane it reacts with both elevons going up. No doubt the solution is to reverse one of the servos but I cant figure out how to do that. I have been using the config

#define REVERSE_CH1_ELEVON        0


 I have been putting this into the APM_Config.h tab.


I have had similar trouble trying to reverse the throttle. From what I can find the command is

#define THROTTLE_REVERSE    0

I also define this in the APM_Config.h tab with no success in reversing it.

I know this is a simple thing but I spent the last 2 days scouring the forums and trying things on my own with no success and I am going a bit crazy at this point. This is the final adjustment I need to make before I make my first flight so I am very excited to try it out!!

    I think the way is crossing the input channels or output channels , some transmitter in the past require this trick if the elevon mix was not tuneable,not allowing minus values.

    You should be able to do all the servo reversing with the DIP switches. Sometimes it takes a little trial and error. I've tried to show a typical delta wing setup in the manual.

    As for Throttle, the way to do it is to change this in the config.h file:

    # define THROTTLE_REVERSE DISABLED
