Its 99.99% likely that Tridges recommendations will solve your problem.
I recently bought pixhawk and the last firmware version I used until recently was 2.67, since then a new method of elevon mixing had been introduced, which had me stumped for a day until I found this page
http://plane.ardupilot.com/wiki/arduplane-setup/first-time-apm-setu...
Make sure to read it carefully in particular the chapter - New style elevon mixing EEPROM setup (ELEVON_OUTPUT option)
yes i already checked this and tested using elevon_output option in manual mode it is ok. i will do next flight after recalibration and will update.
Thanks to every body specially Tridge / Gary
Just Tested with new calibration worked perfect tuned with auto tune. tested FBW_A and auto mode also worked perfect. The P gains were too low as default . will test auto takeoff and land and will update.

Today Auto takeoff worked perfect will try auto landing in next flight any suggestions on approach of autolanding height and distances.
Ahmed, Tridge has responded, it is a setup problem please undertake the steps he has advised.
Gary / Tridge one thing i cant understand it flew one mission with the same setting ok navigating all waypoints and then started orbiting over head.
Hi Ahmed,
Do you have the logs of that successful flight?
One thing to understand that may help you with the setup is that when you enable ELEVON_OUTPUT that is exactly the same as installing a hardware elevon mixer in your plane on the elevator/aileron channels. So all of the flight control algorithms, stability etc is the same on a flying wing as any other plane.
Cheers, Tridge
Hi Tridgell / Gary
If motor stops and plane is in auto mode loitering over head will it decent in glide mode or try to give elevator to maintain altitude . As in my last flight it nose dived after motor stops on low voltage.
