hi all, i just bought a hanger 9 F-22 raptor, just for something to play with. anyway i already have a matt chapman 580,a chipmunk and a nexstar. so the F-22 comes with a jr sport sx600, and has a 10 model memory. i was wondering how to put my other planes on it ? the manual tells me how to change to different models , but thats it. do i need to buy new crystals or receivers ? and by the way it flies pretty stable as a trainer, and with the added flaps and a little tweaking on the throws its a nice sport flier as well. thanks again for any help setting up my remote
