differential Spoilers and elevon_output?

Posted by Andy Fabian on July 11, 2013 at 10:25pm

I can't get this to work.

I've set up elevon_output, and verified that the two elevon servos are moving correctly. I've added two more servos for the alternate pair of control surfaces, and attached them to output channels 5 and 6. I've set their rc_functions to differentialSpoiler1 and differentialSpoiler2. However, I cannot get those two servos to move at all, regardless of what I do with my rudder or aileron sticks, in any manual or auto mode.

Am I missing something obvious? I can provide my settings.

I've implemented (and flown) a fix for differential spoilers, submitted as Pull Request #1736. Source and hex files are also posted here: http://www.etheli.com/APM/ArduPlane_v3.2.0_etMod

  Can differential spoiler setup used to get flaps as well for landings?

Hi,

I'm having the same issue, I couldn't get differential spoiler to work at all.

Here is the detailed description:

Does anybody succeed on differential spoilers at all?
