Why buy if you can build it.
That said. we are tempted to also build our own R/C based of the Arduino.As I am and IT professional I'm tempted to use WiFi for the wireless communication.However I know there are other Wireless R/C technologies out there andperhaps those are better suited for R/C (Like RF22).
If I suggest details chances are the the feedback would be biased, related to the my suggestions, making my request null and void ... sadly that point got lost in translation.
@Hogan,What are your experiences with the RF22 ? Looks like the RFM12B module is cheaper than the the RF24.There is high-power version as well 500mW RFM12BP and according to EU regulations I could find, it isallowed @ at 500mW between 869,400 and 869,650MHz. Not sure though is the 250KHz bandwidth is enough.Thanks for the info links.@PeterHI feel the wifi range would be to short. Most wifi's claim 300m ... but at that distance there are a lotof lost packets. If I could get a decent reliable signal up to 500m I'd be very happy. Hence the <1000m on paper :-)We all know everything looks good on paper ...
