Atto, Europe, telemetry

[brakar]

While we europeans wait for Attopilot to become available i n Europe, anyone knows what will be the prefared telemetry solution? (longest range) brakar

Have just been searching for this and XBee seems t be the most used for most auto pilots including Atto and Ardu.
Most electronics sellers have them listed, check the web.
My only worry is that max range XBee is 900MHz and I have chosen 900MHz video transmission, not sure how that is going to work, if at all.

The setup I have been looking at is this:

XBee-PRO 868 modules are long range embedded RF modules for European applications. Purpose-built for exceptional RF performance, XBee-PRO 868 modules are ideal for applications with challenging RF environments, such as urban deployments, or where devices are several kilometers apart. The XBee-PRO 868 features:

* 868 MHz short range device (SRD) G3 band for Europe
* Software selectable Transmit Power
* 40 km RF LOS w/ dipole antennas
* 80 km RF LOS w/ high gain antennas (TX Power reduced)
* Simple to use peer-to-peer/point-to-mulitpoint topology
* 128-bit AES encryption

By deploying this and any XBee device, OEMs are leveraging the value of the XBee product family and Digi's unsurpassed Drop-in Networking offering of gateways, adapters and network extenders. In addition, XBee users can take advantage of platform agility, the ability to rapidly change their XBee solution with minimal development.

Product summary:

I plan to use it to transmit data from Atto and low res. video. My TX is a Futaba 7C 2.4 MHz

Any comments?

My guess is you will have problems using two transmitters of the same frequency, change your video to 2.4gig and your in with a chance. Transmitters dont get on very well with each other, even if the frequency is different they can still interfere with each other through harmonics, proper attention to aerial instalation ( ground planes etc ) also helps clean things up. The best setup I find is Xbee pro868 with 2.4gig video and a 35meg RC Tranny
Good luck
