"Hello DIY Drones community! I am also interested in hearing experiences with APM 2.5, PX4 and the Paparazzi system. Has anyone tried multiple systems? Did one work better than the other for small fixed-wing UAVs?
Cheers,
Adam"

Jason Beach commented on Chris Anderson's group ArduPlane User Group"@Lorenz - I think there are bigger issues with using HIL simulation for gain tuning such as imperfections in the physics / aerodynamics models employed by X-plane and imperfections in the model of your airplane in X-plane.

Andrew Beckett replied to Jason Beach's discussion Autopilot Comparison in the group ArduPlane User Group"Howdy Jason,
The best place to look for system configuration information is in the APM source code. The configuration register settings for the MPU6000 are in the AP_InertialSensor_MPU6000 class; if you cross-reference the register settings with the…"

Manu replied to Jason Beach's discussion Autopilot Comparison in the group ArduPlane User Group"Hi, it would also be interesting to have some comparison also with the UAV Devboard, as it seems like a potential candidate as well... I'd be curious to have opinions on these boards as well. cheers"

Autopilot Comparison
I'm interested in comparing different open source autopilots such as the APM 2.5, the PX4 or any of the Paparazzis. Has anyone already done a similar comparison? Where's the best place for hardware technical information for APM 2.5 or PX4? (for example the actual gyro or accel sensitivities as configured on the APM--I see from the MPU-6000 datasheet it has several user selectable sensitivies, but which one is the APM 2.5 configured to use or can we still select it?)Thanks,JasonSee More

Jason Beach posted a discussionNew Flight Mode
How difficult would it be for a user to modify the ArduPlane software and create an additional mode similar to FBW-A--basically the autopilot would hold the roll and pitch commanded by the sticks and also maintain airspeed (but not altitude). The idea is that if the aircraft is maintaining a fairly constant attitude and airspeed and then suddenly starts to increase in altitude it is probably in a thermal and a good place to loiter.I want to become more familiar with arduplane/APM (I have the…See More
