I'm writing a proposal for a $2000 summer stipend from my university, for development on an APM UAV.
For the project, I'm looking at the X8 wing. However, I foresee a couple issues:
Most layouts I see have the (3 or 4s) batteries mounted in front, with

Does anyone here use it? I'm trying to ditch mission planner because it's a .net application and it doesn't run properly in
Read more…I watch posts on this forum go for days with no responses. Is there a forum or email list with more activity?
Especially looking for a developer email list or forum because I'm interested in improving APM but I have the occasional question, for exampl
Read more…What's a good strategy to tune these params?
I'm having trouble getting it to hold target airspeed (it seems to stay below it), and I can also hear it changing the throttle quite a bit, even though it's above target_altitude according to the mission p
Read more…I'm grepping through the arduplane code, and I don't see anywhere that yaw is used to hold the course on takeoff. It looks like it uses ailerons to try to correct its course on the ground.
Since ailerons apply a yawing force opposite of their intended

I don't understand how the Parameters.h file works at all. I guess I don't have a full understanding of the C constructs used in it. Can someone ex

I currently have an e-flite apprentice, which gets something like 20 minutes on a battery. I'm looking to move to a different airframe and I'm hoping to
Read more…I would like to see an FBW mode with the following characteristics:
Throttle stick: changes throttle directly.
Rudder stick: changes rudder directly like FBW-A, but does not wind up turn coordination integrator (kind of a separate issue)
Aileron stick:

I managed to get a KMZ file from ardupilot and map it on google earth, but I cannot get it to display in 3d. It just shows a line.
I don't see any docum
Read more…I've mostly given up tuning my nav pid... I have no telemetry yet and my ardupilot isn't very easily accessible, so trial and error is very tedious, and I've never seen D explained in a way I could understand it.
My plane flies to waypoints, but it do
Read more…I'm trying to get my plane to fly the centerline of my neighbor's 1200ft (400m) runway.
So far, I've done all I can to tweak crosstrack, nav pid, etc., but it still gets way too far off for me to consider attempting an autonomous landing.
I've been rea

I've spent a while looking at it, trying to make changes that would make it follow a track better (mainly estimating wind from the difference between the ground speed/

Read more…I just noticed that when I throttle up on the ground in FBW mode, my servo outputs (aileron and elevator) suddenly get smaller (less deflection, like going from high rates to low rates) above about 50% throttle.What is causing this behavior? I would
Read more…I'm trying to set up yaw PID to keep the plane coordinated.
I've set rudder mix to 0 to isolate the yaw PID, and I have to set P to some insane value like 500 for it to have any appreciable effect when I tilt the plane on it's side (thus applying late

DX5e 6-channel radio
AR600 6-channel receiver.
AR600 channel 6 connected to APM channel 8. AR600 channel 5 connected to APM channel 7. APM channel 7 set to mode select. This way I can engage the hardware failsafe to go to manual mode by holdin
Read more…I just started tuning my new ardupilot in an e-flite apprentice. I got the servo pids tuned up well, but I was flying in a lot of wind so the nav pids seemed hard to tune. I didn't get to experiment a lot, because I ran out of batteries 2 or 3 flight

Read more…I've installed my ardupilot into my plane and flown in stabilization mode. I've looked at the tuning instructions in the wiki, and it says to tune the 'P' values for everything. What do the 'I' and 'D' and "INT_MAX" values do?Also, does the ardupilot
Read more…I'm planning on getting an ardupilot mega. My plane is an e-flite apprentice, will it install into it and is the 0.7A BEC sufficient for the ardupilot? If not, what do I need and how do I connect it?
