Question: are 2.4 ghz receivers interchangeable?
Answer: "Are all 2.4Ghz transmitters and receivers compatible? " No , there are several different protocols - DSM2/DSMX , GFSK , etc. If it ends up being too much trouble trying to make your transmitter/receiver work for a plane , you can get new transmitters ( with receiver ) for as little as $26 plus shipping .
