Hi,
If anybody interested in making his own 100 mtr distance tx and rx, check out May Month EFY (Electronics For You). the project is based on Arduino and you can control 3 servos and one esc with this.
Thanks

Nice, just went through it... replacing the 433 Mhz with a Frsky DIY module should be a simple way to extend the range... throwing out ppm

 i had seen rf modules available for arduino specifically (NOT XBEE).. try contacting tenettronics bangalore, they might be able to help you..

Hiiii,  Can you upload the details of that EFU copy please

EFY content is copy write protected, How ever,as this is a perfect solution for beginners with low budget, I will upload the Details from the EFY -
The range of transmitter relys only on the radio module used, A 433 Mhz Transceiver gives 100 to 300 m range,
Where as a costly Xbee PRO gives 1.5K range, with antenna mod, even up to 20KM range can be achieved.
