wow! that statement was taken totally out of context read the entire post fellas. if you have a transmitter that can be programmed for 6 planes why would you want a bunch of extra transmitters laying arround.
if they are diff. channels then you can not use them with your programable radio.
if they are the same freq then why have a bunch of transmitters in your car to get confused with.better get your labeler ready.
each one serves a individual plane they have slightly different clibrations and need to be set up for a individual plane thats why radios have multi model memory to set each plane up individually on there own set up #.
secondly transmitters that have multi model memory are computer radios , and are far better than your basic 4ch sky sport radio again why buy a basic reciever when most flight pcks come with 7 or 8 ch recievers not 4ch and can be used for advanced models if needed.
dave you live in Canada mabee you guys in the great white north can change your freq. christals but in the U.S.A. it is illegal to do so, you have to send your transmitter in for freq. change and recalibration at the factory this is the law for a good reason.
my post was for the questioner and to provide some information to vague and non specific question from his post it sounded like he had a transmitter and needed a reciever or vise versa.
