Quickly browsing through, I would answer the Gyro/IMU question by saying if you are flying the Twinstar you wont need it.  The airframe is tame enough, IR sensors will give you enough stability.

I want to build my first paparazzi aircraft. It would be nice if you
could look over the following list and tell me if you have any
suggestions or recommendations.
I took two frequencies for data and video (868 MHz and 2,4Ghz) to avoid

What I already have:
* R/C Controller with 8 Channels (40 MHz) and a 3 state switch
* 8 Cell Ni/Cd battery pack
* R/C receiver with 8 Channels (40 MHz) (I looked into it and found
the 4017 IC so I think it should be fine)
* Equipment for measuring, soldering and so on

Although I have the RC Controller I'm a total beginner.
What I'm planning to buy is:

Multiplex Twinstar II
including 4 servos and controller
for 157 Euro at

Tiny with LEA-5H GPS
including IR-Sensors
fully assembled
for ~240 Euro at

Gyros / IMU
-> Are they necessary for a good performance of the autopilot ?

Aerocom AC4868-250
250mW @ 868MHz
80$ = ~ 50 Euro @
-> I'm interested in the 15 km line of sight communication

Ground Based Modem
again the Aerocom AC4868-250 as above,
-> I haven't found any module with a metal case (stand alone module
for 868 MHz)
-> If you know where I can get the stand alone module please tell me

Video Transmitter and Receiver
200mW @ 2,4 Ghz
150$ = ~ 95 Euro @

12mm x 12mm x 12mm
Color, 370 Lines
80$ = ~ 50 Euro @

Alternatively I have another video solution but with a bigger camera:
470 Lines with night mode
32mm x 32mm
MTV-53X10HP-K @

FM2350TSIMP + external Control Chip
200mW @ 2,4 GHz
66 Euro @

Video Receiver
90 Euro @
50 Euro @

Do you have any experiences with the different systems and dealers?.
I'm open for ANY recommendations.

I live in Germany so I can't use the 900Mhz modems.

Thank you VERY much
