Hey people, just wondering if nanyone has used these and if they are any good. This is what Im looking at getting instead of an expensive 2,4 ghz conversion. http://www.hobbyking.com/hobbycity/store/uh_viewItem.asp?idProduct=6406&Product_Name=Corona_Synthesized_Dual-Conv_Receiver_9Ch_72Mhz Also, are there any known problems with being able to fly with 72 mhz in town next to a main road? Would I be able to fly without to much concern with interference. Except from posibly someones elses controls (should be unlikely though wouldnt it?) cheers
