My Telemaster UAV with attopilot installed
In my gallery are pictures with descriptions of my build. I will try to update photos and discussion soon.

Very clean installation. Looks great!

Thank you I am in th emiddle of programming and will hopefully have in the air later today or tomorrow. I have to go back to mapping next week.

Should not take long to setup in such a stable airframe, looking forward to seeing the first circle!

I have been programming the Attopilot and have had just a few hiccups. I anticipate that the test flights are going to go pretty smoothly. We will see. I had to make a few modifications to the final instillation. I decided I did not want the xy thermopile underneath to close to the ground and potential rock strikes on takeoff and landing. I am also covering holes from previous installations ( I have had this plane for a few years and have seen a few different configurations). Other than that I do not anticipate having to make many more changes other than trimming the aircraft out.

Make sure you use the ARC mode and record lots of data to help tweak things. I think you will be in for a surprise as to how easy it is!!

I am actually only planning on using the manual and the autonomous mode. Is there a reason you suggest that? Other wise I have the data at 50hz so that I can get all the info out as possible. I have all the sensors up and running so I should have a wealth of data coming down. Thank you for your help.

There is, if you put something dumb in the SET file and don't realise it, like say forgetting an R tag when you want to remap your waypoints and the aircraft sets off on its own to wherever that point was, you can bring it back from the edge of VLOS with stabilization, or turn it roughly back and wait for the maH trigger to bring the bird back into the circle hold.

Ok thank you I will try to make the adjustments. The problem is that the JR 9303 does not have a dial or four position switch. There are sliders but they are at the back of the radio so have to operate by feel That could be a problem of not actually having the flight mode set. i will rack my brain on it and see if I can get it right because I would hate to lose a bird like that.

Yes selecting different modes in all sorts of autopilots is an issue, you could use a three position switch if you have one, off auto and ARC, changing the gains on each position until that setup light flashes correctly for each.

"easy" may be an overstatement. AttoPilot is like all autopilots--it requires careful reading of the manual and a multistep test and setup procedure. Don't expect it to work right out of the box. I'm six months into mine and after dozens of flights and lots of very generous help from Dean and other users, I've got stabilization and RTL working sometimes on some airframes, although I haven't gotten waypoints to work reliably yet. No doubt this is all my own fault and I'm skipping key steps, but I'm no novice ;-)
A few lessons:
--Don't even try it on a rudder-only plane like the EasyStar.
--Make sure you check your sensor orientation and set the SET file accordingly.
--The Locosys GPS can take a long time to get sat lock the first time at the field (15mins is typical for me); don't launch until the light is flashing.
--It's a rats-nest of wires, between the crazy-long SD-card cable and the extra long GPS and sensor cables. Make sure that you haven't disconnected anything when you get it in the plane and make sure the wires aren't binding on servos (I had one tangle today that nearly brought the plane down)
--READ the manual!

I have the final installation and actually it is suprisingly clean and organized. If I choose to stay with this airframe I will actually shorten wires and make it a permanent setup. I have read the manual several times. I do expect glitches and of course have burned Dean's phone up the last two weeks. I have lots of rc experience and have been into UAV's the last few years. I am hoping that all these combined will give me the good luck I need to have this working properly fairly quickly. I have been doing aerial mapping for about a year and perform aircraft accident investigations. Have been doing this with the Condor on Micropilot. The Condor is my user photo. Wish me luck as the manual tests start tomorrow. Also I am uploading a picture of the finished nose and tomorrow I will take pictures outside so that everything can be seen well. I will upload a sample of my aerial survey product as well into my gallery.

Easy is a relative term Chris, compared to things I have used before it was easy! I agree about the rats nest of wiring, that came as a bit of a shock, but the IMU version has a few tricks up its sleeve to remove a few of them, not least the very fact that the XYZ heads are not there any more, so there's two off the bat. The microSD card cable will be a thing of the past as well I believe. As always, less is more, will be interesting to see how you get in UAVpilot. I do think Dean has very much sorted the unit out for wings. A set file from the MelborneUAV would not be very far out in setup I would have thought.
