RE: Range check each flight or day?
I range check my planes in between each flight and also check the control surfaces for a bad or loose clevis. My first range check is the recommended distance and then just 30 feet or so. Only takes a couple minutes and I'm usually alone at the field anyway. The reason I do this is because all my planes are kit built scale ones from .20 size to 30% giant, glow and gas. They all have great meaning to me. I at least want to know that I did what I could to prevent a crash. I haven't lost a plane "YET". An old-timer told me it's better to be safe then sorry. I would feel horrible if my plane went out of control and hurt someone.
