I added dip switches for both TX and RX modules to change operating channels, also i made the transmitter base bit better. But the most important thing i did is that i made some better quality ( comparing to my first ones) cloverleaf and skew planar antennas.
They say that these antennas work best on the 5.8 ghz band because of the frequency characteristics, and you certainly can feel the difference. Video link was solid , thus i did not fly too far because im still not comfortable to fly only with the live video. Anyway, if you have a 5,8 ghz tx rx system, i suggest you to make these antennas, your first or second attempt may not work as good ( fourth attempt for me till i managed to make them look good) so don't give up if it does not fulfill your expectations
