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/
  • The SDK-AC4868-250 FINALY is on my DESK!

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
