Hardware that I use:
- RCTimer ArduFlyer 2.5.2
- Spektrum AR600 reciever
- Turnigy 9XR transmitter with Orange DSM2 module
- Dell Precision M4600 with 64-bit Windows 7 Ultimate.
Software that I use:
- X-Plane 10 retail. The free Demo version can be used to test that it works, before buying the full version.
The Demo stops accepting joystick inputs, and puts a splash screen on the main window after 10 minutes, but funnily enough, the APM still have control.
- ArduPlane 2.76 HIL firmware
- Mission Planner 1.2.84 build 1.1.5044.12328.
You will need to change firmware on your APM.
If you are using an APM in a flying model for this, save your parameters first for an easy roll-back to flight configuration.
1. Upload the HIL simulator firmware to the APM2.5 using Mission Planner.
2. Reset the APM to defaults by using MP terminal - setup - reset, and reboot the APM with the reset button on the board.
3. Connect a reciever to the APM. It will be powered from the APM, so there is no need for a battery to it.
I use 6 channels PWM, but PPM should also work.
4. Switch on your Radio TX, and calibrate radio in Mission Planner.
Radio calibration only seems to work when Sim-Link is running.
4. Install X-Plane 10, and any scenery you want. Scenery is not...Continue Reading

A diagram on how to connect the MinimOSD to the APM2.5 S0 port, and parameter changes needed for it to work.
This is a way to get the MinimOSD to recieve data from the APM, without having to connect to Mission Planner, or placing a switch between telemetry radio and MinimOSD, when using the regular telemetry port.
Although I have drawn straight cables, I recommend that you put a connector somewhere in between for easier maintenance.
You also want to keep the pins on the MinimOSD input for connecting your FTDI-cable to do configuration and updates of the MinimOSD.
Never connect the FTDI-cable to the MinimOSD when the APM is also connected.
I didn't include the camera, vTX or 12V-power as that will depend heavily on your setup, but how you connect those have no impact on this mod.
The MinimOSD I used for this diagram is the 3DR-version. If you have another MinimOSD, pay close attention to the signal names printed on the MinimOSD.
Regardless of which OSD you are using the connection should always be:
APM 5V - OSD 5V
APM GND - OSD BLK
APM TX - OSD RX
APM RX - OSD TX (You might not need this connected. See edits below.)
Next, change the parameters in Mission Planner - Adv. Parameter List for SR0 as shown in the other pic.
After you are done, the MinimOSD will always initialize, and recieve data from the APM. It does not matter if you have telemetry or not.
As with all changes and modification of the hardware,
check, double-check and check again, until it...Continue Reading

Here's how I spent mid-winter:
One of these:
But the booms in the kit were a bit short for my taste, so they got replaced by 14mm CF tubes.
Those have now been replaced by 15x15mm Alu, as I never liked the vibrationlevels with the CF-tubes.
Cut them to 400mm which gave me a CC between motorcenters of 650mm.
The motor mounts sucked, so the got replaced by homemade 2mm alu. See pic. below.
After working hard to reduce vibration, it flies really good. Vibrations are down to +/- 2 on all axis.
Alt.hold and loiter are solid. Missions perform flawlessly.
RTL, and Circle tested OK. Radio and battery failsafe working as advertised.
Follow Me with an Andropilot Cell Phone tested OK.
The AVDome and the CN06 Plus bundle made a noticable difference on flight and navigation performance. Highly recommended.
