One other question for you Dave, the antenna on every RC reciever I have ever owned is 39 " which is 1/4 wave at 72 MHZ... But all the manufacturers also use a 39 inch antenna on their 50 MHZ receivers even though 1/4 wave at that frequency is about 55 inches... Im guessing its just easier to use an antenna from stock than make special ones for 50 MHZ. Is there any reason I should not leinghten the antenna to 55 inches on my 50 MHZ FS8 [sm=confused.gif]???

The more I think about your explination of narrow bandwidth of the FS8 and the possibility that my Transmitter may be a bit off frequency the more it makes sense[sm=idea.gif]. I will be sending my TX module and recievers to you to be tuned together ASAP. Thanks for the great support and I will also be buying a couple flight recorder units as soon as I get my range problem fixed
