Set Alt_Ctrl_Alg to 1, and Lim_Pitch_Min to -55. The first tells Ardu to
make hitting altitude the first flight priority."

Can't seem to allow "Swooping" or steep descents

How can you get your APM to allow your plane to descend aggressively at high angles? We've been messing around with the MAX Pitch and MIN Pitch parameters; but, while we can get the plane to climb…Continue

APM Unexpectedly Stopped Outputting Gyro Data - Strange LED Behavior

My senior project group bought a new APM board set about a month ago and had been testing out waypoint flight/landing in the Xplane simulator and stabilize mode in real flights with a lot of success.…Continue
No APM servo outputs from any channel

I can't seem to get any outputs from the APM to the servos or the propeller motor.All LEDs are working as the should on the red APM board and on the IMU board. This includes the blue flashing light…Continue

Peter Cathcart replied to Peter Cathcart's discussion Can't seem to allow "Swooping" or steep descents"Yeah Xbee has been extremely helpful for in-flight parameter tuning and other troubleshooting, but we have not done anything with disconnecting the ground station, loosing the Tx signal, or experimenting with those fail-safes. But I'm sure…"
Dan Ho replied to Peter Cathcart's discussion Can't seem to allow "Swooping" or steep descents"By the way Peter, are you using Xbee? If so, have you tried disconnecting the ground station to see if the plane will go to RTL mode? I have APM v1.4 hw and v2.23 sw and have my RC Rx failsafe set to put APM into RTL mode if it loses…"
Dan Ho replied to Peter Cathcart's discussion Can't seem to allow "Swooping" or steep descents"Hi Peter,
Thank you for the explanation - that's interesting. I haven't used any conditionals yet and would not have known that the sw would look for a conditional that's listed after a waypoint before the plane even reaches…"
Peter Cathcart replied to Peter Cathcart's discussion Can't seem to allow "Swooping" or steep descents"Dan,
So we actually figured out a way to do this, though this might just be the "brute force" method, but it seems to work. We found that "swooping" is not actually controlled through the parameters but through conditional…"
Dan Ho replied to Peter Cathcart's discussion Can't seem to allow "Swooping" or steep descents"Great question Peter. I want to do the same. I hope Chris or one of the developers will answer.

My senior project group bought a new APM board set about a month ago and had been testing out waypoint flight/landing in the Xplane simulator and stabilize mode in real flights with a lot of success. Then all of the sudden, the LED's on the IMU board start acting differently when powered up and we realize there is no longer any gyro data output from the APM. On the "Flight Data" screen in the mission planner, no roll or pitch information is showed on the HUD. And when in stabilize mode, the…See More
