I had the opportunity to pick up an Audacity 50 heli and and a Align 450xl with a JR xp9303 radio. The radio is FM and in near mint condition as well as all the other gear. and have a good supply of servos with the unit. I picked it up for a song so thought I was getting a great deal for a beginner. My question is the FM radio still usable with current servos? I know I need a fm receiver but will current model servers work with a FM receiver. Long term I hope to build a y copter and am hoping I am not stuck. My only experience with RC was a sailpane 40 years ago. I am probably going to sell the Helis as I didn;t know how big they were. Any help,comments, tips would be appreciated,
