Tom replied to Alex O.'s discussion APM 2.5 Alt Hold (SCARY!..)"It looks like they are a little high. I would try to balance your props a bit more. If you have them 100% balanced then I would start looking at your motors and prop adapters.
Also, I would look at you Mag calibration (compass). You might have…"

After checking out the links above, I tried again and I finally managed to generate a graph of the accel values. Could you please take a quick look at the snapshot below and give me your opinion on whether the x, y…"

Here are some videos that Randy did that help with logs.

Michael King replied to Alex O.'s discussion APM 2.5 Alt Hold (SCARY!..)"I am very interested in this.
Just curious but would the Vel Max/max auto affect this?
The pilot Vel Max is 16??? but the auto settings are -16???
Is the negative correct? The pilot version is positive."
Marcel S replied to Alex O.'s discussion APM 2.5 Alt Hold (SCARY!..)"Hello. This is my first time writing, so I really hope somebody can help me. I'm a beginner in this field.
I have an APM 2.5 board with firmware 2.9.1b (and the latest version of Mission Planner) on a home-made quad and I'm having a very…"
Alex O. replied to Craig Elder's discussion APM Copter 2.9.1.b has been released"I wasn't aware of that bug. Is it an 2.9.1b issue?
At least you had the telemetry and recording tlogs; otherwise, you would have had nothing in your hands to work with.

Alex O. replied to Craig Elder's discussion APM Copter 2.9.1.b has been released"David Dewey's Crash!..
May I ask why wasn't there flashlog in the APM?
Is it because David disabled it? Or is it because there was a glitch in the system that prevented the log being recorded?
I think the flashlog is the most helpful…"
Alex O. replied to Craig Elder's discussion APM Copter 2.9.1.b has been released"Exactly my words...
I don't understand the rush to be honest. In a few weeks all these problems will be solved (Thanks go to Development team). I don't see a reason to risk my platform at this moment.
Still using 2.9.1 Not perfect!.. but…"
Alex O. replied to Craig Elder's discussion APM Copter 2.9.1.b has been released"I think you should wait.
I am waiting for the stable release.

Alex O. replied to David Chanel's discussion Hexa copter crash unexplained !"I looked at the picture. How is that possible you are missing a component?
Do you think it wasn't there to begin with? Or came off during your crash?"
Alex O. replied to adriano nocenzi's discussion telemetry and gps option"Are you looking for a telemetry over a video (embedded into a Video signal)? If yes, Eagle Tree makes good stuff. Not the cheapest though...
If you do not (and won't) have a video downlink system then just get the telemetry module made for the…"
Alex O. replied to Alex O.'s discussion What PID parameters do DJI settings correspond to in APM Code?"Thank Jeff,
I know it is difficult to do one to one comparison. APM give you the world of parameters, DJI gives you almost nothing. I have had other stabilization systems prevously and they would generally have one adjustable parameter called as…"
Jeff P replied to Alex O.'s discussion What PID parameters do DJI settings correspond to in APM Code?"I think what would be best for you is to read through the information on these forums. Ardupilot is very different then DJI Naza or WKM as far as editable parameters go. There are many more configurable fields in Ardupilot and it would be difficult…"
Alex O. replied to Alex O.'s discussion What PID parameters do DJI settings correspond to in APM Code?"I am not looking for detailed answer; just for some guidance.
I am pretty sure someone has the answer to this question:)

Alex O. posted a discussionWhat PID parameters do DJI settings correspond to in APM Code?
As I learn more about the PID tuning this question got stuck to my head.I have DJI Naza as well and Naza software lists all the parameters under two main Gain groups:1.Basic Gain2. Attitude GainsUnder the Basic Gain, you have Pitch, Roll, Yaw, and AltitudeUnder the Attitude Gain, you have only Pitch and Roll So are there all P gains that we are adjusting there? And if so, do the Basic Gain correspond to Rate_P of APM code and Attitude Gains correspond to Stabilize_P?See More

- I have always had interest in UAVs for as long as I have known myself. When I was a kid, not only UAVs but even R/C aircrafts were almost impossible to get. Nowadays with the advance technology, there is a big hope for the civilian users like us. I am happy and optimistic about civilian UAV development. I am mostly interested in traditional heli UAVs but any type of UAV could be in my interest...
