I am Szilard Fulop from Hungary, who is familiar with sw, linux, GNU and rc, but new on electronics.
I keep in the air some planes in the last one and half year, what was very interresting, but not enough :-) Now I want to expand my p-13 glider to be able to made photographs, videos and allow to made FPV flights assisted by autopilot controll and autonomus. This is a great 2,5m wingspan, 1.4kg weight electric glider, which is now under reconfiguration.
Completed:
- I complied and installed the paparazzi3 on Ubuntu/Dapper environment.
- Rebuilded my p-13 and achieved the first flying test with simulated weight.
- Captured the video system: CAM520 line, 1W 2.4GHz transmitter, diversity receiver with thwo 12dBI patch and a GD520 google. Now I am in building this together.
- Replaced the 420 with a 520 CCD, because the first delivered was failed.
- Rebuild 2nd time my p-13 after a crash during the first flight with FMA Copilot
- Tested the video system on fly! ;-) it was a dream!
- Tested the FS8CPI from FMA in an EPP plan. The sensors make great works, but the receiver is very weak in range!
- Buildup pan/tilt servos and test. Some EMI detected, but solved.
- Capture of assemled Tiny boards! :-)
- Retest of FS8CPI failed, replacement to a Futaba R168DF, which works well
- Replacement of video encoder AV100U to a Plextor Convertx TV402U
- Build up of my notebook and finishing the mobil base system
- With new 168DF I switched my RC signaling to PPM from PCM and now I am able to use the AeroPix gyro over FF9 training connector and hopefully will be able to catch PPM signals to Tiny...
- Achieved the first full imotion FPV flights with perfect video and full orinted piloting!
- Captured the final platform a Blizzard from Reichard! The wingspan is 3,5m...
- I switched on my tiny!
- I installed it on my old estarter http://silas.fornax.hu/album/flying/200710/tiny/
On going:
- Calibration! I have a lot of question on this area...
- Ordering of an SDK-AC4868-250 or a separate receiver and a ConnexLink...
- Deal with IR sensor to produce a correct artifical horizon
- My first flight plan plans: failover return to home, simple circle around home
- Fly it in AUTO1, AUTO2 and if stable transfer it to p13

Some captured answers
Q: what are this time the most problematic things over the EMI? just in sentences.
A: - everything
- the GPS is sensitive to the distance and orientation of the video and modem antennas
- and the IR sensors, gyros, and wires to these sensors are sensitve to the video/modem emissions
- and of course the R/C is affected also - mostly from the modem
- the video sends a continuous wave at a very high frequency, but the modem sends "blocks" of data, so even though it is operating at high frequency, it is "turning on/off" at a much lower frequency, frequencies similar to R/C or analog sensors
