IT works!!!

I never did see that alttude tab when you put a placemark. Its super easy to change the altitude.

Here is a screenshot:

The screen shot you show affects the entire path. Unles "absolute" is selected, then the altitude data in .kml is meaningless for my/our purposes... need to know absolute altitude avove sea level, like is reported in the GPS nmea sentences... so only option is to use "absolute" in GE.

If "relative to ground" is selected, then inputing "100m" just reports 100 in kml file, not actual ground alt above MSL + 100 like I really desire.

So my only work around for now, is you move curso over the are of path and check the MSL altitude of that ground by viewing the bottom left corner of screen... then set absolute alt of path as some offset above ground alt, then do a 3D tilt to verify path is above ground... save path as .kml and plug through the windows app.

You are correct, though in my case I live at sea level so I guess i can do that relative to ground thing. But I still cant do that for the path, only individual waypoints.

I would really like to test the cross country ability of this autopilot. I was thinking for maximum duration, a stable F5J airframe. Does anyone have any thoughts/opinions on something like: http://www.soaringusa.com/products/p...ategory_id=267

I would plot the way points over old roads that are no longer used in the middle of no where and follow with my car. My buddy would drive my car and I would be in the passenger seat looking at video from the plane as well as looking at the plane while standing through the sunroof with my Tx ready to take command. I would also use APRS transponder to track the plane using a moving map display a la google earth with cached maps (or cell phone connection) and/or Microsoft MapPoint. Possibly send the GPS co-ordinates via the audio carrier every second to MS MapPoint and use a radio trasciever to broadcast the address to the local APRS repeater every 5 minutes. Another radio would decode the APRS broadcast data and map on Google Earth.
Opinions welcome.

Wow - that plane looks like a floater! Nice aspect ratio on the wings. You might need a few hundred waypoints, or not. Don't forget there is no distance limit between waypoints with AttoPilot.

I live in a relatively populated area, so I test high-WP "missions" by driving around in my car with AttoPilot interfaced to my laptop PC, and have ASCII character 7 ("Ding") sent to terminal server when I hit each waypoint. By the time AttoPilot is shipped at end of Sept, I'll have done some much longer flights than current 8 km, as I have friend that lives in desolate desert area South of Phoenix AZ.

Simo10 - what is the issue? Do you mean you cannot create paths, or you cannot set the altitude of a path?

There is no problem, but as you said, if you set the altitude for the path, the whole path will be raised. I cant do a gradual climb with the path method, but I can with the individual placemarks (waypoints).

While surfing the net for a new platform for my autopilot I encountered this bird:

http://www.warbirds-rc.org/artman/pu...r_Storch.shtml

Looks like the Miss2 but with 5 inch more wingspan.
I ordered immediatly one to test it with a picopilot onboard.

US based guys can find it here:

Update Sept 17


All - Personal messages to be sent to the beta testers in the next couple days. (my day job as Eng is Sunday-Wed, I get Thurs-Sat off). These PMs will be to get ball rolling on addresses to ship units to, forms to sign and fax back to me, etc...

I have trimmed the list of beta testers down a bit - but no worries if you are clearly an interested person... two people can't be found on RCGroups anymore (I'll search again), and 4 others have given no participation since an initial "count me in" 4 weeks ago, and/or they (only 1 person) want to use an airframe that is not consistent with what I stated in the requirements. That cuts out 6... down to 13 or 14, I'll have to check to be sure. I personally like the smaller number, it will be easier to handle all the feedback.

I took a quick look at that competetion, it is now closed

I've seen the Paparazzi project. A parallel idea I had (maybe someone's suggestion) is to have beside IMU upgrade, a thermophile upgrade. I have done some recent work on thermophiles....when my mind was tired of firware programming upgrades. It should be really easy compared to IMU implementation. I believe I have a thorough understanding of the implementation.

Hope I made the cut. I started on a new Stevens Aero Soarstik last night; the wing folded on the other one and it came down like an arrow through the trees. All I actually lost was the airframe and two servos. I made an aluminum camera mount with tilt and pan; the landing mode (and failsafe) has the camera aligned lengthwise with the fuse and the lens tilted up. The frame was bent but no camera damage! Picked up a Copilot to keep the wings level during testing.

Yes Vince I want you and your soarstik on the beta test list. I considered the people very carefully. Soarstik should be great. So you'll put co-pilot on the ailerons, and Attopilot on the rudder, elev, throttle?


The few people I decided to cut, I haven't heard a peep from them for 4+ weeks. A pre-requisite for a beta tester is that I know I'll get something out of them.

Hi Dean,

for you I thought more on the MAV08 next year , should be then in the USA again, as last year.

I think also, to integrate an optional thermopile sensor is a very good idea, I'm very satisfied with it so far. Don't know if you know this old development thread here of Mr. RC-CAMs MAHI project (virtual horizont based on FMAs thermopile sensor):

http://www.rc-cam.com/forum/index.ph...ic=294&hl=MAHI

Very interesting ! And if you don't know it already, the thermopile sensors of Paparazzi:

Hi Vince !

Since I'm also building my AS (Attopilot-Soarstik ) , I have some questions:

How much flight time are you getting with what weight/prop/motor/battery combination? I'm looking for 30min plus, with 200g payload.

TIA
Peter
