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.
  • Repbuild 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! :-)

On going:

  • Introduction with Tiny board .... cables ... power ... molex .. sensor connections ....
  • Retest the FS8CPI! or change to another receiver.
  • Buildup of the ground system, antenna placement, AV recording, digitalizing, etc.
  • Figuring out, which radio modems fit to my plane?

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
