IVE GOT ANOTHER PLANE COMING- SUPER SPORTSTER. I WAS GOING TO USE THE RADIO FROM MY ELECTRISTAR (PURCHASED SEPERATE FLIGHT PACK FOR SPORTSTER) UNTIL I WAS ABLE TO SELL OFF THE ELECTRISTAR. WILL I BE ABLE TO BUY THE TRANSMITTER ONLY ONCE THE TIME COMES? OR SHOULD I RETURN THE FLIGHT PACK AND JUST BUY A COMPLETE RADIO PACKAGE.
