I just purchased this low cost 2.4 G Computer Trasmitter/Dual Receiver
that is cheap because it does not have the LCD, etc. adjustments built in, but uses your computer to set up and change the settings. It's seems similar to the FASST or Spektrum. (Here is another place to get it from
Of course I promptly broke off the small (about 2 inches) antenna wire on the receiver. My question, before I solder it back: can I add a longer length antenna to replace the broken one (since I will need to take it apart anyway) so I can potentially increase range? If yes, it would increase range, how long of an antenna should I make (between 5-12 inches)?
