"Hi Gregory,
Did you manage to get telemetry and minimOSD to work at same time?
If not, try this parameters setting (works for me on Arducopter 2.9.1 with 3DR radio and minimOSD):
Not sure why but it seems that for Arducopter firmware you need…"

Hello,I'm totally new to this. I wonder how to define the speed APM2 uses to fly from one waypoint to another or during loitering. I read about a parameter called cruise_speed, but I do not find this…Continue

Gregory Keeler replied to Dirk's discussion What are the SR0... and SR3... parameters for?"What parameters do you need to set to have the ArdiCopter APM output telemetry data to the MinimOSD ? I am having problems with no data going to the MinimOSD while using a 3DR radio in parallel. I have tried numerous SR3 settings and I…"
"SR3 is by default the Telemetry. On ArduPlane if you set these params you don't need to request the data. So you can disconnect the Tx from your MinimOSD and the data will still be output on Serial3. But be aware ArduCopter is…"
Max Turnoff replied to Dirk's discussion APM2: How do I set cruise speed?"Hi Mike,
Related question: what does TRIM_THROTTLE do? It seems to be dependant on other parameters and gets changed when I change e.g. WP_SPEED_MAX. The hint balloon relates to other (probably deprecated) param.

Gábor Zoltán replied to Dirk's discussion Plane starts pumping while descending. Altitute oscillations"Also possible that the throws you set on your transmitter are too small. ;)

In some sample setups (for example the Skywalker) they are set to special values...Thanks and regardsDirkSee More
Dirk replied to Dirk's discussion Plane starts pumping while descending. Altitute oscillations"Thanks to all of you. I changed a lot of the parameters and will check them in flight ASAP."
James masterman replied to Dirk's discussion Plane starts pumping while descending. Altitute oscillations"As mentioned, the skywalker params on the download page seem to be way too high.
The other thing to note is in version 2.34 of ardupilot, an i term was added to the default pitch pid params. This caused my bixler to oscilate pitch quite badly with…"
david.collett replied to Dirk's discussion Plane starts pumping while descending. Altitute oscillations"Actually, it looks like there is a newer skywalker.param than the one I last saw (skywalker062311) with more sensible servo PIDS ( ~1 vs ~3).
So you could start there and just turn them down further (try halving to 0.5 and you should see behaviour…"
david.collett replied to Dirk's discussion Plane starts pumping while descending. Altitute oscillations"Hi Dirk,
It's probably "Servo Pitch PID" that is too high.
However,
I'd suggest you may wish to reset the arudupilot and start again with the default settings following this page to tune the PID's…"

Hello all,had my first flight with an APM2 (arduplane 2.34) yesterday. Great experience ;-)I used the parameter set for the Skywalker from the download section.But when descending in automatic flight, the plane started pumping quickly and the wings of the Skywalker were bending up and down like crazy. Really scary. So I switched to manual flight.This is, what it looks like in the log:…See More
Michael Pursifull replied to Dirk's discussion APM2: How do I set cruise speed?"Do you have an airspeed sensor?
Now, to answer your question, there are several different parameters that control things like the speed range used in fly by wire mode B, and there is a MAVlink command to change airspeed. But what you are…"
