X-plane models don't snap to level in stabilize

Hi folks!I've just got my APM2 set up with X-plane 9 and before I've made any changes to pid settings, I find that every plane I've flown will not snap to level when stabilize is activated.  In fact,…Continue

Preparing to Buy APM IMU--should I wait a bit longer?

Hey folks, I'm just about ready to get out the checkbook and buy an APM + IMU.  Does anyone know of a pending revision/redesign/update I should wait for?   Thank you!ChrisContinue

No Serial Communication Possible

Hey folks,I'm on the final step of building an aircraft for my APM2.  It's not been out of its box much since I bought it a few months ago, other than to play with it on my desk, connected to my desktop via usb.  Just yesterday I connected my new xbee telemetry radio to it and was thrilled to see it all come together so easily.Last night, when I installed APM2 into my plane (a skywalker), I could no longer communicate with it via serial--USB or xbee.  I've not been able to since.  The only…See More

Jonathan Challinger replied to spagoziak's discussion X-plane models don't snap to level in stabilize
"Well, with default PIDs, there won't be any "snap." In stabilize mode, it should be attempting to level itself if the sticks are centered. Perhaps you haven't done the radio setup? FBW-A is a different story (and a better mode.)…"

X-plane models don't snap to level in stabilize

Hi folks!I've just got my APM2 set up with X-plane 9 and before I've made any changes to pid settings, I find that every plane I've flown will not snap to level when stabilize is activated.  In fact, all of them climb, some more aggressive than others.  Wouldn't the stabilize routine see the attitude of the plane and adjust pitch to correct it?  Or am I missing something very obvious?Thank you for your advice!spagSee More

spagoziak replied to Justin's discussion Skywalker users? - PID question
"I've read in several posts from Chris Anderson that the default PID settings are "woefully conservative" so that planes would operate safely before over-correcting themselves into the ground.  In those posts, he has advised to…"

"well Ive now  bench tested with a separate ESC and its even lower amps at 25amp where the others are all 30amp and the 25amp ESC now works really well as a 5v regulator and it doesn't get as hot as the one 30amp that was sharing its bec…"

"I didn't mean to suggest that my move to 6v was for brownouts.. .that's for more powerful servos.  I'm going to use a 10A UBEC and add a 3300uf cap on the line.  That'll do plenty to avoid brownouts :) I was thinking…"

"Or more precisely, the internals resistance of the large battery is much lower than the small battery, which is why it can supply the higher amperage with the same voltage. ;) As to the original question: I think I just came up with the ultimate…"

John Campen replied to spagoziak's discussion How to power the APM in the group ArduPlane User Group
"i don't think you need to go up an extra volt to make it 6 volts to avoid brown outs. You just need more amps. Look at it this way. a small 12 volt battery wouldn't likely have enough current to start a car where as a large acid lead 12v…"

"Probably best to buy a dedicated UBEC for that thing.  That's my plan; I'll use a bigger one to drive all the servos and probably power the ardu along with it.  If I need 6v then I'll use a second smaller UBEC to drive juice…"

John Campen replied to spagoziak's discussion How to power the APM in the group ArduPlane User Group
"The problem I am having is that the one BEC/ESC power feed gets that ESC very hot because of the load it has to supply to the APM,GPS,Xbee and RC receiver. Its a lot of load from a small circuit that isn't intended for this. I was wondering if…"

"Please refer to these posts, Telemetry issue, and MediaTek GPS and APM supply voltage, level shifter? both say that using a slightly over voltage will affect the X-Bee and the GPS, so be sure they are powered by a 5V source."
