I just started flying UC after a 40 year lay-off. Fuel up and see how long the engine runs. Don't launch it until the flight time is about 1 to 1.5 minutes (to start...or whatever you are comfortable with). As you get used to it, just extend the time. I built this Deweybird for my wife, Diane, for Christmas to teach her to fly UC. I am using a cheap Carl Goldberg handle with the line it came with and it works fine for the purpose.
