Cruise speed
Hi,I want to adjust cruise speed.At default settings I have a ground speed of about 42km/h (without airspeed sensor), and I think the optimal speed should be lower. In the mission planner I have value "Cruise speed", default 12m/s. I updated it to 9.5, but don't see any change in actual cruise speed.How to set cruise speed?Are these different settings with RTL speed? For RTL I prefer keep it as is - less efficient, but more reliable.Is it possible to adjust cruise speed during flight, providing…

How/where do I access the 'config' area to add in rssi code thing?
#define CONFIG_APM_HARDWARE APM_HARDWARE_APM2
What things should I be warned about doing in there?
Thanks
thanks for your attention..and hope your's help

Ok Im a dummy...I did have MP on my lappy but it wouldnt connect to the apm (would& get 224 of the 235 files & time out). In frustration I removed all MP programs. Now I dont know if I have downloaded the right ones 2) all the software.)
My l/top is 32bit XP. I got .net installed. and MP32-1.2.13.msi but wont install.
something about verify a valid windows installer package. Also tried the zip files but no idea what to do once I open the folder.
Thanks in advance
dear all
just start with APM 2.5 .......
all values about GPS and compass are ok.....
but values about vertical speed, altimeter, etc........ crap! the numbers are rolling..... and no variation of bank if I move the mock-up....
any idea what and where to investigate??
TIA
Just purchased Ardupilot mega 2.5 so i am excited to get started. i am a newbie but i want to design a HIL system with x-plain sending the UAV dynamics to a test bench ( comprising of motor, esc, control surfaces). I will then use matlab simulink state-flow to run the control algorithms. So its exciting and will be sharing the progress. Any advice and suggestions will be appreciated. mega thanx!
Jerry, depending on the gain value you have set for roll to pitch feedforward, you may be seeing normal behavior. Many airframes require some "back stick pressure" while banked, which is the purpose of that gain term. In an elevon configuration it can produce the behavior you describe.
I don't know if this is the right place to ask this question. How do I set the P-I-D values for my CAMERA GIMBAL using APM (Mission Planner). I use APM-1 board.
If it can be set, I would save tons of my time...
Hi, I noticed in stabalize mode, in a turn my elevons only go up, not down, but when I pitch the plane up they move down. I've tried every combination under configuration, and can't get them to work.
I went ahead and launched my x8 and put it in stablize mode, I noticed it turns a little to the right. I tried to trim it, but didn't help. Is this related? I did set level before taking off.
Thanks!
Hi guys,
I was wondering if you lost Radio signal, will APM 2.5 switch straight to RTL and bring your plane home and circle until you have radio signal again?
Do have to program that in or will it do it automatically?
Hi Doug,
Wow ! Flight testing UAV autopilots ! I can't disguise some envy. Thanks for the explanation, my knowledge of PID control dates some 20 years back and I wasn't that lucky to use them in my every days' job. My guess was that a PID loop that fits for a system with inherent delays would show some instability if those delays are removed. But it was based un uneducated intuition.
