Did anyone catch this the other day -
HobbyKing Daily - Orange RX 433 MHZ Module (http://www.youtube.com/watch?v=K0PHaOAVDbg#ws)
I have to admit, I've never really thought about a long range system (mainly because my quad's battery won't last long enough for it to get that far). But talk about simple - module fits into a 9X and away you go. I'm presuming it will be cheap as well.
The only thing it seems to have done so far is upset the OpenLRS dev, as it's a copy of this... I must admist I haven't looked at the details, but my first thought was that (depending on the specifics of the license) you pretty much grant people to use your code both recreationally or commercially.
Any opinions... I did note that all the LRS's I've seen have great big whip antennas, and this has a tiny stub in comparision, will this be any good ?
433MHz is not legal in the UK for model control, however 459MHz is legal.
433MHz is only legal for model to operator telemetry.
Yep, although OpenLRS did produce a 459Mhz version IIRC - although who knows if you can flash the firmware on this.
Looking at the antenna for the Tx side it will be a lot shorter on range than most other UHF solutions. A quick swap over of the antennas should / could get more potential from it.
It is though limited to 100mW and with that stubby antenna I`d say it would have around 3-4km range max in stock format only.
Says it can be programmed from 400-460mhz.
Got a be worth a pop at that price.
Cheers, Mark
I believe this is an OpenLRS clone - a bit more info here: http://www.diydrones.com/profiles/blogs/how-about-open-source (http://www.diydrones.com/profiles/blogs/how-about-open-source)
probably has the arduino bootloader so can flash any firmware you like.

Yep, its on the HK site and tells us we have to be programmers to use it :D still do nt understand the issues with openLRS, open source generally means that people can clone it, and commercialise it unless there's specific exclusions in the license.
OpenSource is generally free to use, but not to make profit.
But as it's china, and they don't have copyright laws.......
Most OpenSource are generally under the GNU or CreativeCommons license, and you can't sell the material.

Believe it or not, in China they do have very restrict copyright laws but only applies to Chinese products normally :)
The OpenLRS was released under GLP so it's perfectly fine to copy and sell.
Do you mean GPL? Yes, I've just been reading up on this, infact the GPL license itself states that it is totally ok to re-sell any code, but two conditions must apply:
1) You must state that it is GNU GPL
2) You must make the source and code freely available.
This means someone is perfectly allowed to then buy a copy from you, and sell it on themselves! :)
