Thanks Dragonfly Joe. I love my Spark but the controller took a nose dive. I tried to repair it but at my age, eyesight and shaky hands its hard for me to work with those small parts. I can go up and down and rotate, but no left, right or forward or reverse. The joy stick is dead. Took it apart and found the ribbon cable broke loose. But I can't get that little bugger back into its socket.
