Hey hey, you never mentioned you were in Australia!!! That changes… well not much, but still. Where about? I’m in Melbourne.
DX7 is fine, that is what I use. AR700 is a very good RX for FPV too.
For transportability (a word?) you want something like a flying wing or a funjet, both a pretty small. The easyglider is like a small cularis, the wings come off, but still its a little bulky. Then again it depends how and what you are traveling in.
If you have a solid setup it is easy to fly… at least I think so. You don’t loose orientation when you are looking from the planes POV.
The easyglider is a nice setup, and not too expensive either, especially the way I set mine up. All up (excluding the airframe+rx+lipos) it was under $100 for servos, esc, brushless motor.
1km is doable in good conditions with a DX7.
I use a 900MHz setup but would like to move to 1.3GHz but that is only so I can do tricky things with 900MHz modems.
I would say go with 900MHz as its more available, and longest range.
I get most of my gear from RV: http://www.rangevideo.com/index.php?mai … Path=35_21
