"Hi HK & Kim,
The idea of transmitting all the telemetry over the video link seems like the way to go as it would reduce cost, weight and power - every little bit helps. Have either of you found any further information about it or tried it…"

The file that needs to be hacked is the control_modes.pde file.
The dipswitch settings are controlled by the following lines:
mix_mode = (PINL & 128) ? 0 : 1;

ModeratorPaul Mather replied to Kim Halavakoski's discussion ArduPilot telemetry downlink to GroundStation?
"Typically, you would just split the ground and the TX from the GPS to both your auto-pilot and your OSD. Then hook your X-Bee to your auto-pilot. There are two products that do what you're asking. Melih from Flytron came up with a way of…"
Kim Halavakoski replied to Kim Halavakoski's discussion ArduPilot telemetry downlink to GroundStation?"Hey HappyKillmore,
Do I just need to split the the signals with a Y-cable or similar or do I need something else to split the signal?
I guess this is the standard way to go, however, it would be nice to use the Video TX for downlink to the…"

"You can split the data stream from any of the GPS units and send it to both your OSD and your APM. Then have the APM send the telemetry stream to the ground via X-Bee. If you just send the GPS data down as telemetry, then you won't get any…"

Hello,I'm a UAV newbie and I am investigating the myriads of possibilities in building a UAV platform. I have chosen the ArduPilot mega + IMU as my autopilot platfrom and all is good with that. The next thing is to figure out the groundstation setup. There seems to be many ways of doing this, and all solutions are not compatible with each other :) Now to the question: - I will use a 1500mW 1.3Ghz video TX on the UAV for the video feed. - I will use a OSD to display "telemetry" data on the video…See More
Kim Halavakoski commented on Jordi Muñoz's blog post How to boost your 2.4Ghz Spektrum/JR Transmitter signal!"Hello,
has anyone modded Hitec Aurora 9(Spectra 2.4Ghz) module/transmitter with this? I'm just curious about how to connect the antenna cable, since the HItec modules have no U.FL connectors visible...probably inside the module case but has…"

mighty interesting project! :) I'm trying to do the same thing and have a long-range signal between my ardupilot and my UAV, and was considering Xbee 868 modules but due to some problems with the duty cycle I started searching for other…"
Kim Halavakoski replied to Reto's discussion Xbee Pro long range made affordable until end of February 2009"Hello,
has there been any progress with this duty cycle issue with the 868:s? Has anyone tested the "solution" by Noth666?
Does it work reliably?"

- Regarding EasyStar vs Twinstar -- do you want ailerons? I have no flight experience yet, but it seems that ailerons and straight wings are likely to give better waypoint navigation, but you will have to figure out how to hook up the twin motors (the extra motor and ESC will also cost extra money). I decided on the EasyStar because it looked easier, and the airframe is only about 1/5 the total cost, anyway. Also, the pusher-prop seemed recommended for greater durability during landing (can't break the prop on the ground). You could always change to a new airframe later.

- HD Pro 20A ESC

- Ailerons planned, but not implemented yet. Ordered a new set of wings to make the aileron mods on(+the current wings are getting quite dented from the numerous crashes while learning!)
I also got a GoPro HD camera for filming the flights in HD and also video tx/rx 1.2Ghz 1500mW transmitter with a MSH-36 camera. I have not installed all FPV gear yet, but I am testing out flying with the GoPro mounted with this setup
Here are some videos of my first flights(No FPV/UAV yet, just basic flying / learning with a GoPro mounted):
