"Thanks Chris for taking the time to explain in detail. I suppose there is so much happening "behind the scenes" that we (i.e., the users) don't see. BTW: is it anyhow possible to join the dev mailing list in order to stay informed? As…"

I'm really hoping that someone in the community can help a fellow drone hobbyist figure out this GPS mystery.I have an Ardupilot Mega 2.0 (Ardupilot 2.50) with an external MediaTek MT3329 GPS…Continue

Ger Harris replied to wraith's discussion question on fpv spotter"Roll of spotter:
AMA rules (Yes but there are reasons for the rules)
FPV is disorienting if you need to switch out of FPV in a pinch. A good spotter should be able to reorient you quickly or give quick commands in an emergency.

Andre S replied to Ger Harris's discussion A Humble Request for Software Versions"Hi,
I've been thinking along the same lines and didn't want to raise it because I was feeling bad about asking for more work of those dev volunteers. But in principle I think having a "stable" and an "experimental" line…"

Ger Harris replied to Garrick Merrill's discussion Loss of RC inputs during flight"It looks like you lost RC input within seconds after you throttled up, and at that point your stick positions appeared to be fixed. To me, this appears to be a "brown out" type situation where your receiver didn't like the…"
Ger Harris replied to Ger Harris's discussion A Humble Request for Software Versions"Thank you Chris for the response. I'm not going to disagree with you, I'm going to merely embellish what I would like to see.

"1) There is. Public code (in the Mission Planner) is stable. Trunk code (in Git) is development.
2) There is. It's on the Wiki Project News page.
3) See above

Ger Harris posted a discussionA Humble Request for Software Versions
I am actually fairly new here, but I am one of those people who follow the threads eagerly looking for the next software release with bug fixes and feature updates. To be sure, so far I've had some great success with my APM2 Bixler FPV drone. Right now I am a little uncertain whether I should attempt to fly with the current software version I have installed, and it seems that this answer SHOULD be a lot simpler to find out than it is currently. Right now I have a lot of time and money in my…See More

Ger Harris replied to criro1999's discussion APM2 - Rudder position on Stabilize mode"There is something wrong here:
1) I am not familiar with there being a stabilize function where it uses the rudder. My successful setup only uses ailerons and elevators - Not rudder. To my knowledge the only reason why you would use rudder instead…"
Equipment:
Hobbyking Bixler
Ardupilot Mega 2.0
External MediaTek MT3329 GPS
3DR RadioTelemetry Kit-915 MHz
3DRobotics Bixler electronic chassis
Spektrum AR8000 Receiver (Spektrum DX7s Transmitter)
808 #16/#11 HD Key-chain Cameras
Velcro Secured / Carbon reinforced wings
6x4E Propeller
Weight: 786g Drone / 1100g full FPV
Modifications:
Carbon Rod installed inside stock Bixler Wing Rod
ESC installed on outside right for heat control
Removed cockpit magnets due to possible interference
Reattached wing horns with Gorilla Glue (bad crash with pre-attached horns)
Reglued wing spar with Gorilla Glue (again, bad luck super glue here)
Packing Tape over wing spar
Velcro/Fishing wire secured 808 #16/#11 Cameras
Electronic chassis secured by rubber bands!!
Balanced to 61cm
DX7s Channel 8 - Gear channel control APM modes
DX7s Channel 6 - AUX1 - control Geofencing enable
Throttle failsafe modified below throttle normal range - RTL Activate
Future Modifications:
Lost Plane Alarm + Low Voltage Sensor
FPV Transmitter - Security or GoPro?
I found my best balancing point is 1.5mm forward from the center wing spar line. Yes, I fasten my electronic chassis with rubber bands as the stock magnets seem to interfere with the compass.
I had a bad crash were the ARF Bixler wing spar became completely unglued in flight. The resulting crash completely tore off the front nose. (Unrelated to anything having to do with the APM modules) Using a heat gun to melt and reform the nose, and Gorilla glue I was able to get the Bixler flyable again.
1) AR8000 receiver on the bottom right with satellite receiver on the top left perpendicular to each other.
2) External MediaTek MT3329 GPS module on the top. (Required extension cable)
3) RadioTelemetry Kit-915 MHz top right
4) 808 #16 Spy Camera for in-flight video
5) APM2 module with 10cm servo extensions for easy installation and removal.
6) Lost plane alarm below telemetry radio.
Better view of hole drilled out to serial/USB access to the APM2. Also, you can see the lost plane alarm underneath the telemetry radio.
Servo extension cables feed out the back and are labeled for easy installation in the field. APM2 module fasted to bottom with nylon screws.

Combining Live View / Telemetry / Mission Planner
Posted on August 24, 2012 at 5:00pm 15 Comments 3 Likes
This my version of seeing everything working together without an OSD. I used this video view to tune the Bixler from the stock parameters, and to get a good idea of how everything all works together.
This video focuses on way point missions (auto) and geo-fence breaches (guided). Please note that everything is not as smooth as I would like it to…
