Some pictures of the TERN build

Cutting of corner reinforcements. They will be glued into the fuselage to allow the rounded bottom shape without loosing the strength of side and bottom connection.

Start of the inlet duct for the fan.

Inlet duct ready cut.

Trimming of fuselage front with hot wire. If the temperature of the wire is high enough it cuts through the PU glue without too much of a hitch.

First try to shape the fuselage. I have to revert to the sharp knife for the time, because I damaged my nice power supply for the special corner cutting tool.

Fuselage with the two main bulkheads. I used a selfmade sandwich foam/glass because I just had it. Naturally one can use 6mm (1/4") plywood for those. The wing stumps are still to be made.

Position of fan

Behind the fuselage is the UC blanc which I still had from another project.

View from the tail end. The bulkheads are not glued yet.

Indication of how inlet ducting fits in the fuselage.

Razor 6DOF IMU + Arduino + DCM

I recently got SparkFun's 6 IMU board and played with it a bit. Basically I connected Arduino and Razor 6DOF board and ported DCM code. Code is ArduIMU v13 but just made to work with Razor board. I am not sure what to think about gyros on that board as it takes them a while to "warm-up". Below you can see run from cold start for over an hour and "zoom' on first minute or so (just raw ADC values). On the link referenced above, you can see same data plots for both gyros and accelerometers.

I also modified ArduIMU Labview code - mainly that "cube" is within main window rather then separate one. I haven't compiled the code but whoever has LabVIEW should be able to run it (developed with version 8.5)

ArduIMU V13 Officially Released!

Hi there, finally is here and includes many improvements thanks to Doug Weibel. Try it out! here.-Coordinate system has been corrected.-The gyros are now in order X,Y and Z.-Extra LED status, including no yaw correction (Yellow), GPS fix (Blue) and Gyro saturation (Red).-Improved Ground Station, with Labview 8.5 files and executable for windows.I also add some boards to the stock here. I have to increase a little bit the price because i'm really getting nothing. Also the demand is so high that i can't keep them stocked (more demand = higher price)...Thank you a lot for your support!

Is there a problem with the "old" ArduShield?

In my testing trying to get the ArduPilot to work with Remzibi's OSD, I'm starting to notice that the serial output of the ArduPilot is intermittent at best. For the most part, I show the blue GPS lock led, but it does turn on and off for no reason on occasion.Has anyone studied the ArduPilot source enough to know how much additional processor power is consumed with the ArduShield connected? I have two ArduShields (both "old" ones) and neither will return more than about 3% of the GPS data being sent to it.I'm using my GPS Emulator at 38,400 and I've varied the Hz from 1 to 10 with no significant change in output. All of my testing is working absolutely fine without the ArduShield attached.Anyone got a guess?

The flight previously known as roof crash

Reverted back to 2.4Ghz & got the footage which previously ended in a roof crash. Right click & you'll find a menu option called "View Image". Click on View Image to get a full 8 megapixel view.

Pointing towards San Francisco.

Pointing towards NASA.

Pointing towards Fremont. VicaCopter is itching to crash on 1 of those roofs, you can be sure.

Integrated 41 frames to defeat the haze. Since we haven't corrected the lens aberration with this camera, can only integrate a small part of the image.

The nose was actually centered on Onizuka Air Force base, where Major Marcy is believed to be until it closes in 2011. Then She's leaving the area & we're probably going to get depressed & quit flying again.

Had the C328 on 900Mhz for live preview. The video from the C328 was awful as always but good enough to aim.

The 2.4Ghz bitrate dropped out, but at least was recoverable by rotating the antenna.Information on the aircraft is on vicacopter.com.The image stacking software is on heroinewarrior.com.

80" Wing - suitable as a platform for UAV

Work has stared on a 80" Flying RiteWing - based on a TL60 with an added 20" centre Section.Powerplant will be 4S 10300 mah Lipo, at about 800 watts full throttle, but should cruize at 200 watts, so about 45 minutes flying time. Expected weight is 3.5 kg, and should be able to carry a fair bit more payloadThe wings remove, so transport is only 2 x 30" wing sections and one 20" centre section.The Wings only house one digital full size servo each, so nice an simple, everything else is in the centre section.Also will be running (removable) landing gear.Build photos so far :-)

The full build thread is here http://www.rcgroups.com/forums/showthread.php?t=1129487 and also here http://www.parkflyers.org.nz/modules/newbb/viewtopic.php?topic_id=557&forum=9&post_id=9869#forumpost9869After she is flying will use as a platform to get into auto-pilots, starting with a RTL function

Thats where I am so far. Yeah I know I have a long way to go!I found this member of diydrones today! I was really excited to see he was using the same basic platform.He is doing exactly what I want to do!!!!!!!!! How cool. Check out his project and you will see what I am trying to accomplish. As I progress, I will update this post. Feel free to drop tips and advice - they will be much appreciated.

I just found my internet home!

I can't believe the treasure of information, and people that make up this website. I am so excited to have found it. I plan to be an active member from this day forward.I am an eager beginner to all this. I have been flying RC Airplanes for only about 3 years now, and have always had my eye on the goal of using an RC airplane to get aerial photographs and video. I am completely obsessed with accomplishing this goal! :)Here is how I progressed so far in the hobby.I started with Air Hogs brand two channel planes. They were cheap and gave me the basics of flight.Here are the ones I have had or have:

Next I bought this "Fastlane Avionic", a two channel plane with rudder control for turns and throttle control for climb. It was fun, but hard to control. It didn't have throttle differential so controlling altitude was a challenge. I crashed this plane badly, and when I went online looking for parts I found out the product was discontinued. BUT - it is now sold by Megatech and is called "Cosmic Flyer". I ordered the parts I needed to fix this plane up recently and am excited to fly it! Again this was a cheap plane and it helped me get better understanding of flight. (Lost Cosmic Flyer/Avionic in a tree after the rebuild - I will miss this little airplane.)

Next I bought a Hobby Zone SuperCub.

This is an excellent 3 channel trainer. I took it to a high school football field near my house and taught myself to fly there. The plane has a "auto pilot" feature that uses two sensors to see the ground and sky. If you dive or climb, or turn too sharp it takes control and gets your plane stable again. I found it to be disasterous for my first few flights so I removed it. Now I fly pretty well...and I am ready to put a camera on this plane and get some pictures.Most recently I bought a 102" powered glider called a Super Easy Fly.


Another of the same plane but in french.It is 4 channels with full throttle, aileron, rudder and elevator control. I am interested in using this platform for my photo/video but I have been reading terrible reviews on the plane. People say the dihedral on the arelons causes the ESC to get super hot. I haven't flown mine yet. It is all put together and hanging where I can look at it, but so far I haven't been able to arrange a good day off from work to go try it out.I am still looking for the perfect platform.Lately I have seen the HawkEye system to be FANTASTIC and have been saving money to get one.I wonder if it could be set up with all the fancy autopilot stuff?Also, Mike Powers from Whispershots.com has AMAZING platforms. He has been very kind to tell me where to get his plans in kit form and I am going to be ordering very very soon!The one I like the most is the Passive system.

You can see it here http://whispershots.smugmug.com/gallery/8254126_gnHh7/1/505079989_XuKY2/MediumI have also been told by Mr. Powers that the LoRyder system is really good for flying in congested areas. Ill be looking to get as much overtime as possible at work! :)I have two teenage sons that are also interested in UAVs, We want to some day operate a small business together doing low altitude aerial photography.As I pursue the attainment of my goal, I look forward to meeting members of this community and learning from your experiences, and sharing mine, as limited as they may be. I have a massive amount of information to digest here, but this community seems to be the resource I have needed so badly.Feel free to contact me about any thing at any time.James

Problem with Hobby Zone Super Cub FOUND!

Since I bought my Super Cub, I have had a recurring problem. During flight - and ONLY during flight, sometimes the rudder or elevator will just do its own thing - locking up in full deflection one way or the other and. Usually this leads to a downward spiral into the ground and a trip to the hobby store. My girlfriend thinks I just suck as a pilot and should give it up - lol - but its not me! Its an electronic issue that has now been solved (3 days after I ordered a brand new replacement plane from HZ).Anyway, if you own a super cub and have had this problem....here you go. This is the answer.http://supercubclub.proboards.com/index.cgi?board=motors&action=display&thread=1631

That sinking feeling...

Above the Fog from Jason Short on Vimeo.

This is a video of me loosing my plane into the sun and fog for almost 5 minutes. I was just testing my AP that i've been working on over the last month and a half and it was my first flight with working waypoints. I tuned everything way down, but it was working ok so I let it run loops around the T3 course. One thing I turned off for debugging was altitude control. In hindsight, that was a mistake. I could have just dampened it down more, but I shut it off entirely.The plane slowly climbed the entire time and before I realized it was pretty high. Eight minutes into the flight she turned right into the sun and fog bank and I didn't see it again until four and a half minutes later. I was panicking I couldn't take over manual, because it was in the fog. I even thought about running to the car and chasing it until I realized I had no idea where it was. Last I saw it was headed out to sea. I had nothing to do but wait and count the $ to replace it.I stared at the sky for what seamed ten minutes and all of the sudden I saw it gently doing the T3 above me. I put it in FBW and brought it straight down. Enjoy the video, I edited out the 4 minutes of circling. You can hear me fussing with the radio, and I one point I put it in Manual and turned it left in a futile effort to find it. I just put it back into AP and hoped I did a good job. The plane will fly again.
