"Thanks for the suggestion!
The project supplies all are Geroge Mason University's property. I will probably buy a Pixhawk for future projects. "

"Thanks to everyone who helped me with this project. The video below shows our Quad following waypoints (of a lawnmower pattern). I will consider the advice on z axis vibration.
Thanks again!"
Thanks again!"
"Here is the video!"
"Today I balanced my Props and flew with INS_MPU filter at 20. I still get pulses while on Alt_hold but the APM seems to compensate it while on Auto mode within +/- 2 meters. I got some data for my presentation which is tomorrow. I will also try…"
"Thank you for the response Randy. I have attached IMU log here for reference.
I believe I have the Kyosho zeal vibration absorption Gels which should be good enough but according to log (attached), my Z axis accel readings have a high (0 - 20)…"

"X and Y vibration levels seem fine (+/- 3):
the Z vibration level, however, is a bit abnormal:
Would this much vibration effect the alt hold?"

"The quad shot directly up whenever I switched to ALT_HOLD. the logs show that the desired value was at -15 meters. Interesting. "
"I couldn't find AHRS_MPU6K_FILTER but I found and changed INS_MPU6K_FILTER to 20 (was 0).
I am going to set alt hold param to its default value of 1 and go fly right now even though it is like 9:53 pm. :)
Thanks Much!"

"Yesterday with the downgrade I was able to get waypoint navigation to work well (EDIT 1) with jerky alt control. I am not trying to fix alt_hold mode to work. The only value I am playing with is the Alt_Hold P gain (EDIT 2)."
"Should I try downgrading to an older firmware? the barometer problem is really annoying. "
"I flew again today first with an Alt Hold P gain of 1 and then I increased it to 3 and tried it again.
Stabilization when Alt Hold P gain = 1:
Stabilization when Alt Hold P gain = 3:
Both flight logs are attached.
Alt hold controller seems…"

"I think the only thing that I had not calibrated yesterday after downgrading was the accelerometer.
I will do it now and give it a spin this afternoon. "

"My Alt hold P gain was set to 1.5 so I decreased it to 1 (which I assume is the default value). I will give it a spin today and see the results.
Wouldn't more P gain give me a faster controller."
